How to manipulate xen image size
...is an image file
of 4GB.
We want to use this image file as a template for creating Xen guests which
their disk will be an LVM device.
The disk image file is of type:
file /var/lib/xen/images/rhel52.img
/var/lib/xen/images/rhel52.img: x86 boot sector; partition 1:
ID=0x83, active, starthead 1, startsector 63, 9221247 sectors;
partition 2: ID=0x83, starthead 0, startsector 9221310, 19438650
sectors, code offset 0x48
By dd/cat this image file to an empty LVM device
cat /var/lib/xen/images/rhel52.img > /dev/VolGroup00/rhel52
and by using this configuration file...

I tried opening it with virt-rescue, but for some reason the zfs-fuse

work. I opened a bug to look at enabling ZFS:

Merging os and updates
I've been able to successfully kickstart CentOS 3.9 from the base
repo, but no such luck after merging os and updates. I think I did
everything right - updated base/comps.xml and regenerated
hdlist/hdlist2. Updated the yum repo as well although I'm pretty sure
it's not used by anaconda.
This is difficult to debug. The setup is running under kvm on a CentOS
6.4 host, and for some

Re: Bug#637234: linux-image-3.0.0-1-686-pae: I/O errors using ext4 under xen
Hi Konrad,
Does this look at all familiar? There is some more info in the full bug
log at http://bugs.debian.org/637234 . In particular, contrary to the
message below, the user subsequently confirmed that the issue appears to
be Xen specific (doesn''t happen on native or vmware) and that it arose
between 2.6.39-2-686-pae and 3.0.0-1-686-pae.
Could it be related to edf6ef59ec7e
