After upgrading from 6.3 to 6.4 starting a pre-existing x86 virtual machine causes the libvirtd daemon to SIGSEGV. The VM is running CentOS 5.9 x86 and is sharing both physical LAN interfaces using macvtap virtual interfaces in bridge mode. At present one physical LAN interface is disconnected.<br />
<br />
I also have a CentOS 5.9 x64 VM with almost identical configuration which runs fine after the upgrade. Both worked fine on 6.3.<br />
<br />
The top of the /var/log/libvirt/libvirtd.log log is shown below. The remainder seems to be info about cleaning up after the failure to access the macvtap4 interface.
