Re: [libvirt-users] installing and accessing a VM? - newbie question maybe

You just need to setup connection to the remote libvirtd instance. For example if you use ssh, it could be s simple as qemu+ssh://root@that_server/system, in virt-manager you can set it up as connection, for virsh and virt-viewer you can use it as an argument to -c parameter, and so on. If you're still craving that pure-terminal pleasure, though, you just need to setup serial console in the guest. I don't think you need to setup anything in libvirt for the VM, because otherwise 'virsh start --console' wouldn't work then. Quick "ubuntu serial console" [1] shows what looks like chicken and egg problem. The thing you need to do is make sure the console is used by the installation process. It is usually done automatically by most distros, but it looks like ubuntu doesn't do that. I have no idea how the installation process can be configured on ubuntu, my guess is just that it won't be there merely due to the target audience of the distribution. Again, as Google is your friend, even with bad words used for the search, some old guide [2] is still around fourth result. And that's something virt-install can do for you as well, just open the manual and look for "location allows things like --extra-args". To try it out, I had to run it with DISPLAY= nad --graphics none so that it does what you wanted, of course you can/should remove those options. But this works for me: DISPLAY= virt-install --os-variant ubuntu16.04 -n ubuntu --memory 4096 -l \ http://mirror.vutbr.cz/ubuntu/archive/dists/yakkety/main/installer-amd64/ \ --disk none --extra-args console=ttyS0 --graphics none Just so you know, you can use libvirt as a non-root user as well (without sudo) if configured properly. And you might need it if trying to remotely connect to the daemon.
