[Bug 771227] Re: Domain save/restore does not work (kvm)

[Paul McEnery]

I've been trying this out every time a new version of Ubuntu is coming up for release, and it has never worked! However, this is the most promising result that I have seen to date. Maverick version of virt-manager seems to be able to correctly save the running state to a file, however it prompts you for a save location. It does not default to the location down /var/lib/libvirt. However, there appears to be no way to restore the VM through virt-manager on maverick. Despite this, I could successfully restore via virsh as follows:

$ virsh restore debian.save

In this case, the console springs to life inside virt-manager - with the
VM in the running state that I saved. This is the behaviour I would
expect to see.

In terms of reproducibility, I have a Fedora and Debian guest. Neither
are restorable on natty. They both simply start booting from scratch on
restore.

I am very encouraged by the how good things are looking on the
virtualisation front on natty. As I was saying, this is the closest that
I have come seeing this work seamlessly since libvirt and virt-manager
were included.

I suspect there is an issue with this particular version of libvirt. If
I get some time I'll try rebuilding the 0.8.8 package with the 0.9.0
source and put it in my PPA.
