Today after updating kernel-xen to 2.6.20-1.2933.fc6xen on one of our host I got kernel oops and machine rebooted, when it come back again i have no other choice but to edit grub.conf and make the last working kernel ' 2.6.19-1.2911.6.5.fc6xen' the default one which working fine.
DemU(s) working fine with with same kernel 2.6.20-1.2933.fc6xen, we use loopback mounted fs for domU(s)
Here are the messages i found on screen before machine got rebooted (Note: machine is remote to me thousands of miles away therefore i can't check its boot screen :-S )
Now I am reluctant to update kernel-xen on our other remote hosts, never got into such issue on FC6 while updated kernel-xen. In help/suggestion will be greatly appreciated.
