[Xen-users] Hard powered off, now domU hangs at boot. Help.
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: Started domain server Bootdata ok (command line is ro root=/dev/VolGroup00/LogVol00) Linux version 2.6.18-53.1.14.el5xen (mockbuild@builder6.centos.org) (gcc version 4.1.2 20070626 (Red Hat 4.1.2-14)) #1 SMP Wed Mar 5 12:08:17 EST 2008 BIOS-provided physical RAM map: Xen: 0000000000000000 - 0000000020800000 (usable) No mptable found.

The domU filesystem was screwed up a bit, but fsck was able to fix. The reason it appeared to hang at the console is that I had forgotten that I had configured the domU to popup a VNC session; all the interesting information was being written there rather than to the console. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
