Guest OS won't boot, how to boot from cd

Postby dguilbeau » 2010/08/03 17:52:48

Here is my getinfo.sh data: http://pastebin.centos.org/33998

I have 1 guest os, windows 2000 server. It was running fine, then gave me an error that it could not read c:\??? and please run chkdsk. (Sorry, I didn't write the message down.) So I shut it down (properly, start, shutdown, etc. not just turning it off.)

When rebooting, it hangs on what looks like a BIOS screen:

HVMAssist BIOS, 1cpu, Revision <...snipped...>
ata0 master: <...snipped...>
ata0 slave: <...snipped...>
Booting from Hard Disk ...

Is there a way to boot the guest os from a cd or cd image (.iso file), so I can try to run chkdsk or a recovery install?

Thanks,

If you are using Xen as your virtualisation mechanism then you can edit the /etc/xen/whatever config file and change the line that says

Code: Select all
boot = "c"


I think "d" means to boot from CD. You'll then have to hack the file around to point the virtual CD at an iso image.

If you aren't using Xen then there should be a similar way to do thigns for KVM/Vmware etc.

Thanks for the quick reply. I guess I just needed to step away from it for a while. There is a "Boot Device" option under the hardware settings for the Xen guest. Yup, boot from cd-rom is an option.

Thanks again,
