Re: [Xen-users] CentOS ISO how to boot in Xen guest system
2008/10/13 James Corteciano <linux@xxxxxxxxxxxxxxxxx>
Hi Steffen,
I try to mount the partition in dom0 and however this is what the error message said:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
dom0:~# mount -t ext3 /dev/server/centos /mnt/temp
mount: wrong fs type, bad option, bad superblock on /dev/server/centos,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
dom0: dmesg | tail
...............
VFS: Can't find ext3 filesystem on dev dm-14.
...................
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I have got a wrong entry in /etc/fstab inside the domU system which cause of not booting properly. Is there anyway I can do to mount this /dev/server/centos in dom0?
What you try to mount above is a whole virtual disk. You have first to make its partition seeable from your dom0 by using "kpartx -a /dev/server/centos". This will create for you entries (one per virtual partition) in /dev/mapper. Then you have to mount the entry that corresponds to your virtual root.
Thanks!
James

You don't have to.
Just mount the partition in dom0 and repair there!
