Hyper-V is an awesome native hypervisor for Windows, and It works surprisingy well with not only Windows but also Linux, freeBSD and Docker. But when using Hyper-V, it used to be not easy when you want to get information about your VMs and interact them with SSH. But now, with
hvc command, these problems can be solved really easily.
Not all feature is available to the platform. This tutorial only tested with Windows Server 2016, Windows Server 2019, Ubuntu and Debian. Please try yourself whether your VM works.
Also, use an elevated console when executing the command. The easiest why you can simplify this process is to download scoop and install
scoop install sudo. Now you can simply type
sudo hvc instead of opening an elevated console.
hvc allows you to show basic information about your VMs. Using
hvc list can show you a list of Virutal machines you have:
You can also get specific inforamtion about your VM such as VM ID, its IP address and its current status using
hvc id <Name of VM>,
hvc ip <Name of VM> and
hvc state <Name of VM>:
As for the name, if your VM have a name that contains space, you shoud quote it:
You can complete some simple management of your VM such as start or stop using
hvc <command> <name of VM>:
|start||Starts a VM.|
|stop||Shuts down a VM.|
|kill||Powers off a VM.|
|restart||Reboots a VM.|
|reset||Issues a hard reset to a VM.|
But keep in mind that nothing will be shown if the action is successful.
You can connect to your virtual machine using different ways via
hvc, like socket or ssh.
You can connect to your VM’s serial port using
hvc serial <VM>; You can also connect to your VM via a socket connection using
hvc nc [options] <VM> <port>; You can also directly open the VM Graphic Console using
hvc console <VM>.
Here I will mainly talk about its feature on SSH.
scp, which works just like normal
scp but you can just input its VM name instead of its IP address. Here is a small demo:
To use this command, the only thing you have to do is to setup SSH server on your VM. for Windows, you just have to install OpenSSH Server to start; for Linux, besides normal SSH server setup, don’t forget that install Hyper-V tools before using the command. For example, Debian 9 need
hyperv-daemons package for
hvc ssh to work. For other Linux, please check here for the supported Linux distros.
These command really simplified my life and I no longer need to pin Hyper-V Manager in the taskbar. Just have a try, you will love it.
