Virter SSH Integration

The simplest way to connect to a virtual machine that was started with Virter is to use virter vm ssh .... However, you may also choose to use ssh and related tools to connect. This can be made very convenient by adding the following to your ~/.ssh/config:

Match exec "virter vm exists %h"
    User root
    IdentityAgent none
    IdentityFile ~/.config/virter/id_rsa
    KnownHostsCommand /usr/bin/env virter vm host-key %n

Now you can easily connect:

$ ssh foo
[root@foo ~]#

Name resolution

Depending on your configuration, ssh may or may not be able to resolve the VM name to a hostname. If not, you will see an error similar to:

$ ssh foo
ssh: Could not resolve hostname foo: Name or service not known

Fix this by installing and configuring the libvirt NSS modules. In particular, you will need to install a package such as libvirt-nss or libnss-libvirt. Then add libvirt_guest to the hosts: configuration in the file /etc/nsswitch.conf.

SSH integration with qualified names

If you have configured a network domain in your libvirt network, you can also connect to the VM using the fully qualified domain name (FQDN). For instance, with the domain name test, you can use this configuration in your ~/.ssh/config:

Host *.test
    User root
    IdentityAgent none
    IdentityFile ~/.config/virter/id_rsa
    KnownHostsCommand /bin/bash -c 'virter vm host-key "$(basename "%n" .test)"'

Now you can easily connect:

$ ssh foo.test
[root@foo ~]#
