如何在不访问主机的情况下将 ssh 连接到 KVM 来宾 VM？

Question

I have set up a VM and the VM is accessible from the host through the SSH also.

The host has a public IP and accessible through SSH. the guest VM can access the internet like pinging to google is working with the bridge connectivity.

For example: the host IP is ( xxx.xxx.xxx.xxx) The vm IP is ( 192.168.yyy.yyy)

Is it possible to SSH the VM without accessing the host from a different network?

Answer 1

As explained here , you find out an IP address of Linux KVM guest from Linux host itself

$ virsh list
$ virsh domifaddr rhel7

But that does require access to the host.

You would need to configure libvirt, which comes with its own in-build DNS server, dnsmasq , as explained in " Automated DNS resolution for KVM/libvirt guests with a local domain " from Roland Wolters in order to reference the guest VM directly, through a FQDN, instead of an internal IP address you cannot have without host access.
