since upgrade from qemu-kvm 0.10.5 to 0.10.6 (Debian Lenny, Packages from
http://www.corpit.ru/debian/tls/kvm/, kvm module from kernel 2.6.30)
live-migration does not work anymore.
After "migrate -d tcp:192.168.0.2:4444" info says "migration completed",
but "incoming" kvm machine dies.
Any hint how to debug this?
What do you mean exactly by "dies"?
Not sure if this is related but this is what happens on my system when I
try to do a live migration with kvm-88 and the latest kernel 2.6.30
(gentoo 2.6.30-gentoo-r5).
