Are the needed patches in 2.3.0-rc0? Is it possible to backport AHCI migration to RHEL 7.1 qemu or will it be too much work?
The patches that improve the stability of AHCI migration are in 2.3-rc0. We still have not /enabled/ migration upstream, but editing to code to allow it is fairly trivial -- it's just a true/false value in the code.
I built 2.3.0-rc0 but also added RH patches which applied (mainly for pc-q35-rhel7.1.0 machine type support) from http://ftp.redhat.com/pub/redhat/linux/enterprise/7Server/en/RHEV/SRPMS/qemu... After suspending and restoring VM prints the following and hangs: [root localhost ~]# [ 43.595571 irq 23: nobody cared (try booting with the "irqpoll" option) [ 43.596004] CPU: 0 PID: 0 Comm: swapper/0 Not tainted 3.17.3-200.fc20.x86_64 #1 [ 43.596004] Hardware name: QEMU Standard PC (Q35 + ICH9, 2009) .

I will try with a pure qemu w/o RH patches later. Regards, Nerijus
