[Qemu-devel] qemu/qemu-kvm-0.12.1.2 - migration still very slow

[Nikola Ciprich]

Hi,
few months ago Pierre Riteau reported regression of exec migration in qemu.
(http://lists.gnu.org/archive/html/qemu-devel/2009-08/msg01557.html)
There was some discussion, but there is no clear conclusion.
Today, I tried qemu-kvm-0.12.1.2 and migration is still very slow (using
libvirt save command, which internaly uses migration) to suspend vm
with 4GB of ram can take almost half an hour, although system is not loaded
at all.
Is there some way to speed things up?
Any tips would be greatly appreciated...
with best regards
nik
