Hey guys,
next try is without libvirt, but still no joy.
After issuing 'migrate -d <url>' on my sending host (qemu-kvm 0.11.0), I
get the following output on the receiving host (qemu-kvm 0.12.4):
(qemu) Unknown savevm section or instance 'slirp' 0
load of migration failed
... leaving my vm broken.
Am I doing something wrong, or is the format of the savevm file just
different and should I abandon all hope of ever doing a live migration
to a newer version of qemu-kvm?
Thanks in advance,
Nils
