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.
