Systemd segfaults after live migration

[Mateusz Kwiatkowski]

After live migrating my virtual machine it panics because of segmentation fault in systemd (see attachment).

Software used (on archlinux):
qemu 1.7.0-1
libvirt 1.2.0-1
linux 3.12.7-1

This is configuration of this VM:

Hi Mateusz,
  How are you migrating? If you are using the compress/xbzrle option, try turning it off and see if that helps, there are some corruption fixes for xbzrle in 2.0.0.

Can you still reproduce this issue with the latest version of QEMU and libvirt?

[Expired for QEMU because there has been no activity for 60 days.]
