Re: [Xen-users] CentOS ISO how to boot in Xen guest system
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?
Thanks!
James

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 > > > On Sun, Oct 12, 2008 at 7:16 AM, Steffen Heil <lists@steffen-heil.de>wrote: > >> Hi >> >> > How to boot the centos dvd image (/download/centos/centos5.2.iso) in xen >> guest system to let me do linux rescue command? >> >> You don''t have to. >> Just mount the partition in dom0 and repair there! >> >> Regards, >> Steffen >> >> > > > -- > Linux Registered User #380364 > > > _______________________________________________ > Xen-users mailing list > Xen-users@lists.xensource.com > http://lists.xensource.com/xen-users >_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
