A failed UPS caused the physical server to go down hard.  Someone in the office attempted to restart the server without the external SATA drive containing the domU images correctly attached. Now when I attempt to boot the domU, it hangs. The same problem occurs if I try to boot the domU into single user mode as well.  I’ve run fsck on dom0 and didn’t find any problems.  Does anyone have any suggestions?  This is rather urgent.


Both the domU and dom0 are running CentOS 5.1 x64. The console output is:
