I know there are some patches that are already accumulating for qemu 2.1.2 that I think are migration related. mst, does that assertion `!n->vhost_started' sound familiar? yes, a known bug, will be fixed in 2.1.2 qemu-2.1.1-2.fc21 has been submitted as an update for Fedora 21. https://admin.fedoraproject.org/updates/qemu-2.1.1-2.fc21 Package qemu-2.1.1-2.fc21: * should fix your issue, * was pushed to the Fedora 21 testing repository, * should be available at your local mirror within two days. Update it with: # su -c 'yum update --enablerepo=updates-testing qemu-2.1.1-2.fc21' as soon as you are able to. Please go to the following url: https://admin.fedoraproject.org/updates/FEDORA-2014-11180/qemu-2.1.1-2.fc21 then log in and leave karma (feedback). qemu-2.1.2-2.fc21 has been submitted as an update for Fedora 21. https://admin.fedoraproject.org/updates/qemu-2.1.2-2.fc21 qemu-2.1.2-2.fc21 has been pushed to the Fedora 21 stable repository. If problems still persist, please make note of it in this bug report. Because of that BZ, the latest QEMU packages for fedora21 are broken with pseries booting from a virtio disk.
When looking at the source RPM, I have spotted the following patch file:
0006-virtio-pci-enable-bus-master-for-old-guests.patch

Subject: [PATCH] virtio-pci: enable bus master for old guests
commit cc943c36faa192cd4b32af8fe5edb31894017d35
pci: Use bus master address space for delivering MSI/MSI-X messages
breaks virtio-net for rhel6.[56] x86 guests because they don't
enable bus mastering for virtio PCI devices. For the same reason,
rhel6.[56] ppc64 guests cannot boot on a virtio-blk disk anymore.
Old guests forgot to enable bus mastering, enable it automatically on
DRIVER (guests use some devices before DRIVER_OK).

This commit has been reviewed as toxic and reverted from the QEMU master branch upstream:
http://git.qemu-project.org/?p=qemu.git;a=commit;h=45363e46aeebfc99753389649eac7c7fc22bfe52
If fedora21 is supposed to act as an hypervisor for pseries guest, you should consider reverting
this commit as well.
