Dear libvirt community,
Using recent Ubuntu Stein Cloud Packages, we are observing random libvirtd live-migration crashes on the target host. Libvirt is having a SEGFAULT with the qemu driver. Transferring block devices usually works without issues. However, the following memory transfer is causing the target libvirtd randomly to close down its socket, resulting in a roll-backed migration process.I can reproduce this with large VMs, which have a large memory pool. Could you please also attach the backtrace of the libvirtd process once it crashes? That would be helpful.
