I am running KVM on Centos 6.3 and am seeing an unexplained shut down of
two guests. The libvirt package was upgraded to
libvirt-0.10.2-18.el6_4.4.x86_64 at the time of the shutdown. Only the
two guests shown below was affected, while 9 others running on the same
hypervisor were not.
Can some one help me to find the cause please ?
Regards
Chandana
