Re: [libvirt] libvirt-0.9.1 to 0.9.3-r1: managedsave/save won't start/restore at saved state

I'm seeing strange behaviour, here.  Any guests saved using both

- Tested against libvirt v0.9.1, v0.9.2, v0.9.3-r1 (Gentoo)
- Confirmed on three different hosts Gentoo amd64 systems.
- Tested with gentoo and ubuntu guests.
- Nothing relevant in /var/log/libvirt/libvirt.log or

The "state file" /var/lib/libvirt/qemu/save/<dom>.save exists and is
deleted when 'virsh start' is called.

The new boot sequence is confirmed by :
- VNC console checks
- previous screen sessions lost
- uptime

I've open a bug at https://bugs.gentoo.org/show_bug.cgi?id=376333 but
had no answer.

Any idea on what could happen or how to inspect it?

Does /var/log/libvirt/qemu/<dom>.log show the qemu process getting started with the -incoming fd:nnn flag? While you claim that nothing appeared to be relevant in that log, it might actually help to post a few lines of it for confirmation.

It's working for me with libvirt 0.9.3 on RHEL 6, so I'm not sure what to suggest that you try next.
