Hi,
I understand that Vixen does not support migration at this stage.
Does that also mean that save/restore is also not expected to work
for PV guests running with Vixen?
I tried it and it doesn't work, whereas it does when the guest is
started normal PV. I thought I better check expectations first.
Cheers,
Andy

Migrate and Save/Restore are identical operations (to a first approximation)
One is serialise the VM into a network socket, while the other is onto disk. It is the same algorithm actually doing the work.

Hi Andy,
Correct, save/restore/migrate is not currently working.
