[libvirt-users] Cannot recv data: Connection reset by peer

[Javi Legido]

Bonjour Guillaume.

There's a particular reason to compile libvirt rather than install the
package for Ubuntu Server? And, there's a particular reason to use LXC?

I'm not an expert, but if you just want to start using KVM and install a VM
I can help you through a simpler method.

Regards.

Javier
