[Xen-users] expanding img file

[Paul Eskello <paul.eskello@xxxxxxxxx>]

Hi,

I use xen on centos 5.2 x86 and used virt-install to create a few
virtual machines.

A few days ago centos 5.3 emerged, but I did not allocate enough
diskspace for these virtual machines, only 2 gb. That's way too small
for running yum-upgrade.

So I tried to increase them. With no luck. I found a howto that
instructs me to mount -o loop /mnt /vm/foo.img, but that fails:
"mount: you must specify the filesystem type" .

Specifying ext2 says:
"mount: wrong fs type, bad option, bad superblock on /dev/loop0,
       missing codepage or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so"

In dmesg:
"loop: loaded (max 8 devices)
hfs: unable to find HFS+ superblock
VFS: Can't find an ext2 filesystem on dev loop0."

Another option I saw was just appending a gigabyte of /dev/zero using
dd. I did that, but the diskspace in the virtual machine stays 2gb.

I think I ran outta options.
Any hints or advice ? Besides building new machines from scratch using
the correct sizes ;-/

Regards.
P
