Hyper v shared folder linux

Общий каталог на хосте Windows Hyper-V с виртуальной машиной Ubuntu

Только что установил Hyper-V на Windows 8 и гостевую ОС Ubuntu 12.04.

Исходя из VirtualBox, я ищу лучший способ для совместного использования каталога на хосте / Windows с гостевой Ubuntu.

Я прочитал это: https://stackoverflow.com/a/1386764/913295 и я знаком с самбой. Поскольку этот вопрос не относится к Hyper-V, я поднимаю этот вопрос здесь.

Плохая новость заключается в том, что, в отличие от VirtualBox или VMWare, который позволяет вам определять «Общие папки», которые являются каталогами на вашем хосте, которые доступны гостю, Windows 8 Hyper-V вообще не предоставляет такую ​​функцию.

Хорошая новость заключается в том, что, поскольку в Hyper-V нет такой функции, как «из коробки», для нее не понадобятся специальные инструменты, например, для монтажа. vboxsf файловые системы. Вы просто проходите официальный / стандартный путь, получая доступ к общим папкам вашего хоста как к сетевым общим папкам.

smbclient командная строка SMB/CIFS клиенты для Unix, это инструмент командной строки для доступа к общим папкам хоста Windows. Ниже приведены два примера, которые я нашел. Опять же, ничего особенного, доступ к нему так же, как и к любым другим общим сетевым папкам Windows.

Я отправлю репост в разделе «Настройка общей папки» по второй ссылке:

Нам нужно поделиться папкой на хосте с гостем. Гость может смонтировать это при загрузке. В этом уроке я предполагаю, что мы делимся им из этого места %USERPROFILE%\workspace

В ВМ отредактируйте /etc/fstab :

Кроме того, добавьте файл учетных данных для монтирования для работы. Поместите туда следующее содержание:

Это должно быть так.

Дополнительные ссылки для монтажа на основе графического интерфейса:

Если сначала это не сработало, попробуйте сначала с клиентом на базе Windows получить доступ к общим папкам хоста. Опять же, ничего особенного, доступ к нему так же, как и к любым другим общим сетевым папкам Windows. То есть, некоторые инструкции говорят, что вы «Должен быть создан внутренний виртуальный коммутатор через диспетчер виртуальных коммутаторов» использовать общий ресурс хоста, в этом нет необходимости, и он вообще не дает никаких преимуществ / преимуществ, поскольку мы просто обращаемся к нему как к обычной общей сетевой папке Windows. Напомним, вот шаги:

На хосте Hyper-V создайте общую папку и назначьте всем пользователям разрешение на изменение.

На виртуальной машине, работающей на хосте, откройте Центр управления сетями и общим доступом и включите общий доступ к файлам и принтерам.

На виртуальной машине нажмите Пуск и введите \\host_name\share_name где host_name имя вашего хоста Hyper-V и share_name это имя общего ресурса, который вы создали.

Нажмите клавишу ВВОД, и в виртуальной машине откроется окно проводника, отображающее содержимое общей папки на хосте.

Теперь вы можете копировать файлы с виртуальной машины на хост и наоборот при необходимости.

Hyper-V

Hyper-V is a hypervisor that is included with some versions of Microsoft Windows. It is capable of running an Arch Linux virtual machine. Hyper-V is generally oriented toward enterprise rather than desktop use, and does not provide as convenient and simple of an interface as consumer virtualization programs like VirtualBox, Parallels, or VMware. However more recent versions and builds of Windows 10 and Windows Server 2016 include easier configuration options and better compatibility for Arch Linux. Networking features such as NAT for internal switches, multiple NATs and port forwarding have been added without the need to set up Internet Connection Sharing (ICS). Generation 2 virtual machines also now work properly for Arch Linux.

Contents

Installation

Hyper-V is included with Windows since Windows Server 2008 as well as Windows 8, 8.1 and 10 in the Pro versions. It can be enabled from Control Panel at «Turn Windows features on or off» under «Programs and Features». Activate the «Hyper-V» checkbox, apply the change, and follow the directions on screen.

Network configuration

First, you must configure a new virtual switch so that your virtual machine will be able to connect to the Internet. Once Hyper-V is enabled, start the Hyper-V Manager (search for it, or start it from Command Prompt with the command

Set up a virtual switch

In order to connect your virtual machine to an existing network, either use an internal or external network switch (virtual network adapter). An external switch must be bound (bridged) to one of the host’s existing network adapters (e.g. Ethernet or Wi-Fi). An internal switch can be used for network communication between the host and virtual machines, without the virtual machines having access to the external network. Adding NAT functionality to an internal switch makes the host act as a router for the virtual machines, enabling the virtual machines access to the external network.

Not all networking features (e.g. NAT configuration) can be set up through the Hyper-V Manager GUI. Using PowerShell, run as an Administrator, permits better control over configuration.

External switch

To create an external switch, in the right sidebar, select «Virtual Switch Manager. «. In the left sidebar of the dialog that opens, choose «New virtual network switch». Under «What type of virtual switch do you want to create?», select «External», then «Create Virtual Switch». Type a new name for the virtual switch. Under «External network», choose the network adapter to bind with the external switch.

You will be prompted about network disruption; continue and your network will be briefly disconnected as the switch is configured.

Using PowerShell (run as Administrator), the above steps can be done with the following:

On an Arch Linux virtual machine, choosing the external switch as the virtual machine network adapter effectively bridges the Windows host’s network adapter with the virtual machine’s eth0 interface. The interface can then be set up in Arch Linux through the usual ways (systemd-networkd, netctl, etc.) with a static IP address or with DHCP. The virtual machine will act just like another host in the external network.

For example, if you want the Arch Linux virtual machine to use a static IP, and the Windows host is configured as 192.168.0.100/24 , then the Arch Linux virtual machine interface should be configured like 192.168.0.101/24 , with the same gateway and DNS servers as set up in the host.

If using DHCP for the virtual machine, the IP address will be assigned by the DHCP server in the external network.

Internal switch

As of version 1803 («Fall Creators Update»), Windows 10 has a NAT Switch built in (named «Default Switch») that gives you instant internet access after installing your virtual machine if you set it up to use DHCP, see this Technet blog post, so you do not need the instructions below to get a working NAT switch.

To create an internal switch, follow the same steps as the external switch, however replace the relevant choices for ‘internal switch’. Starting with Windows 10 Anniversary Update (Version 1607, OS Build 14393), native NAT support for internal switches was added to Hyper-V. For earlier versions, Internet Connection Sharing (ICS) can be used to enable network access for virtual machines on internal switches.

To find out which version and build of Windows you are using, on a command prompt or PowerShell, run:

Using PowerShell (run as Administrator), an internal switch can be created with the following commands:

With the above steps, the host and vritual machines can already communicate with each other since they will be on the same virtual network (192.168.3.0/24). The virtual machines however will not be able to access the external network until NAT or ICS is configured.

On Windows 10 build 14393 or later, internal switches can be configured for NAT and port forwarding:

Consult Microsoft’s NetNat documentation for a complete list of commands.

For earlier versions and builds of Windows, Internet Connection Sharing can be used. Open Network and Sharing Settings, and Adapter Settings, where you will need to enable internet connection sharing for your internet adapter that you normally use. Once the connection can be shared, add it to a bridge together with the virtual switch that you created in the previous step.

Virtual machine creation

In the left sidebar, select your computer under «Hyper-V Manager». In the right sidebar, select «New» > «Virtual Machine. «. In New Virtual Machine Wizard, you may in general specify whichever settings you like, but some must be specifically configured.

Under «Specify Generation», you may choose «Generation 1» or «Generation 2». Generation 1 virtual machines emulate a BIOS-based machine and legacy ports. Generation 2 provides a UEFI-based machine. In general, use Generation 2 unless for compatibility or portability reasons you need to use Generation 1. Also, when using Generation 2 for an Arch Linux virtual machine, make sure to disable Secure Boot in the virtual machine’s settings under Hardware -> Security.

For «Startup memory» under Assign Memory, choose enough to ensure Arch and any programs will run properly.

For «Connection» under «Configure Networking», choose the virtual switch you created earlier.

For «Connect Virtual Hard Disk», choose «Create a virtual hard disk», and make sure the «Size» is appropriate for your use case. The virtual hard disk is sparse, so the virtual hard disk will only use as much real storage as is necessary to store what the virtual OS has written to it.

For «Installation Options», choose «Install an operating system from a bootable CD/DVD-ROM». If you are installing Arch from a disc or USB device, choose «Physical CD/DVD drive» under «Media», and select the appropriate letter. If you are installing Arch from an ISO file, select «Image file (.iso)», and select the file in the «Browse. » dialog. For Generation 2 machines, booting from a physical CD/DVD drive is not supported.

Virtual machine configuration

Next, you need to configure the virtual machine’s settings.

If you like, you can add more virtual processors to your virtual machine. This allows the virtual machine to use more than one of your processor cores, which will increase performance in many cases. If you plan to use the virtual machine intensively, you may wish to allot up to half of your processor cores. To change the number of virtual processors, select «Processor» in the left sidebar, then adjust «Number of virtual processors».

Change any settings, then select «OK» to apply your changes and exit the settings dialog.

Arch installation

Once the virtual machine is fully configured, you are ready to install Arch. In the right sidebar, select «Start», then «Connect. «, and a connection window will open. The network should work automatically when the Arch installation media is running; check by using ping on an address you know is responding, e.g.

If no response is received, the connection is not working. If this is the case, you are probably experiencing a bug Microsoft has acknowledged. You can try installing the hotfix from the Knowledge Base page, or just wait a little while and try again.

In general, you may now install Arch as you would on any other system. The Generation 1 virtual machines are BIOS-only (no UEFI), so you must follow the BIOS-specific instructions for the various boot loaders.

Post-installation

After Arch has been installed, you can continue to configure features.

In order to use Hyper-V integration services, install hyperv and start/enable the services hv_fcopy_daemon.service , hv_kvp_daemon.service and hv_vss_daemon.service .

Shut down the virtual machine, open the Settings dialog again, and in the left sidebar, select «DVD Drive» under «IDE Controller» or «SCSI». Under «Media», choose «None». This will stop the virtual machine from trying to boot from the install media on every start.

Shared directories

Files can be shared between the host and guest with very little effort. First, on the host, choose the folder you want to share with the guest, or create it. Open the Properties dialog for the folder ( alt + Enter or right-click and choose «Properties. «). Go to the «Sharing» tab and select «Advanced Sharing. «. Activate the «Share this folder» checkbox. By default, the folder will have read-only permissions, meaning the virtual machine can read from the folder but cannot write anything to it. If you would like to modify these permissions, select «Permissions». Here, you choose which users can access the shared folder, and what permissions they have. In general, you will probably be sharing in both directions and should check «Allow» for both «Change» and «Read». Before exiting the Properties dialog for the shared folder, note its «Network Path», which should be of the form \\computer name\folder name .

Next, you need to find the IP address of the host. Exit the Properties dialog, and open Command Prompt or PowerShell. Run ipconfig . You should see an entry whose name ends with the name of the virtual switch you created (e.g. Ethernet adapter vEthernet (New Virtual Switch) ). Under this entry, look for IPv4 Address and note it down.

Next, you need to mount the shared folder from Arch. Boot the virtual machine. Once it is running, you will first need to install cifs-utils , which will allow you to mount CIFS shares (CIFS is the protocol Windows uses for shared folders). Next, you will need to decide where you will be mounting the shared folder. A reasonable choice would be somewhere in /mnt , like /mnt/Hyper-V .

In the command to mount the share, replace any backslashes in the «Network Path» from earlier with forward slashes.

You will be prompted for the password for the user you are authenticating as. You can specify the password in the command options via password=password , but this is not a good idea in terms of security as the password for the host will now be in your command history file; or if you are running the command from a script, stored in the script indefinitely. Instead, you can use a credentials file, which allows you to specify your username and password in a file with restricted access rights. It can be called anything; for an example, if it were called .credentials and stored in your home directory, it would be of the following form:

After creating the file, change the permissions to restrict read access:

Then you can add another option to the mount command: credentials=

/.credentials . Now, when mounting the share, your username and password will automatically be applied.

For a more concrete example, let us say you are mounting a share with a Network Path of \\PC\share at /mnt/Hyper-V , where your username on the host is «John» and the host’s IP is 198.123.151.23. The mount command would thus be

One problem with this method is that if the host’s IP ever changes (e.g. it has a dynamic IP assigned via DHCP, or moves to a new network), every instance of the host’s IP on the guest must be replaced. However, the smbclient package provides nmblookup , a utility which finds the IP address associated with an SMB host. Thus, in the case of the example above, you would run

You only want the IP address, so you can use head and cut to parse it:

Then you can simply replace the IP address in the mount command:

More ways to mount shared folders, including automatic mounting on startup, are detailed in the Samba article.

Graphical programs can easily be run via Xorg via the xf86-video-fbdev package. Simply install it and the window manager or desktop environment you wish to use, and you should be able to start X without issue.

Setting resolution

Screen resolution is fixed after start-up. It can be adjusted by changing the boot parameters, up to a maximum size of 1920×1080 (the actual limitation is 8MB of frame buffer memory). When booting with GRUB, this can be done by editing /etc/default/grub and adding video=hyperv_fb:[desired resolution] to the end of the line GRUB_CMDLINE_LINUX_DEFAULT . Afterwards, run update-grub to write the changes. An example line may look like:

If you are using systemd-boot to directly boot the kernel, simply add video=hyperv_fb:1920×1080 to the options in the entry configuration instead. For example:

Enhanced session mode

By default, you may suffer from poor mouse and desktop experience. Enhanced session mode features better mouse and video experience and integrated clipboard. This mode utilizes Xrdp and hv_sock kernel module. Run the following code to enable this mode in the guest:

/.xinitrc to start your own desktop environment when log in a Xrdp session. Refer xinit to configure

Then turn off your Arch virtual machine machine, and then using PowerShell (run as Administrator), you need to enable hv_sock on you machine:

After enabling the enhanced session mode, Hyper-V client automatically connects to a Xrdp session after booting.

You can permanently disable enhanced session mode by running the following command on Powershell (run as Administrator):

To connect to a TTY virtual console, you can temporarily disable Enhanced session mode. The Enhanced session mode feature can be enabled or disable for individual machine right from its View menu.

Tips and tricks

You can also do X-forwarding to get a better experience than Hyper-V’s default client. One way to do this is by using a VNC server like TigerVNC and connect to it from Windows. Alternatively, a better way to do this is to install a Windows X Server like VcXsrv (free) or x410 (commercial) and do X-forwarding to get a faster GUI experience. X410 has support for vsock which is more reliable than TCP/IP connection.
