Hi,
is live migration between qemu-kvm stable-0.15 and stable-1.0 trees possible?
When I live migrate a VM from 1.0 to 0.15, the destination side 0.15 qemu-kvm
exits with:
(qemu) Unknown savevm section or instance 'i8259' 0
That's expected, since commit i8259:convert to qdev

Hi,
I am getting a frozen guest when migrating from an Opteron 6274 host (amd

the guest is frozen: vcn screen is still there, but no input is possible and
no kernel output is seen. Trying c on the

The SeaBIOS change is okay with me, but the qemu/kvm change needs to
be accepted
to handle the CPU_DEAD event
in Liu Ping Fan's cpu lifecycle/destruction patchseries, see:
http://patchwork.ozlabs.org/patch/127832/
This ACPI implementation can be used instead of the cpustate virtio/pci device
in the original series.

Hotplugging a vCPU with kvmclock enabled can cause a guest stall/hang. When
the stall happens, pvclock_clocksource_read() is called for the new vCPU and
pvclock_get_nsec_offset calculates native_read_tsc() - shadow-tsc_timestamp.
shadow-tsc_timestamp contains a value larger than native_read_tsc(),
