[Xen-users] Dump an image based domU to a logical volume
Dear all,
I sent an e-mail some days back ... but no answer. Probably it was a bit
too confusing. Going to rephrase it, since I need an insight to solve this.
Part I
++++
How to dump a domU paravirtualized image into a logical volume?
I usually create a domU image because its very portable, and I use it as
a pristine image to create my production domU''s.
Based on the Xen book, I''ve doing doing this by using
"kpartx" to expose
the partitions inside the image, and then I copy their content to
logical volumes (LV) previously created. After some edition on the
configuration files (fstab, grub.conf and the domU xen config file) domU
is ready to boot from the LV.
Both the domU images I''ve been creating till now and the LVM based
domU''s are working just fine.
I always used CentOS or Scientific Linux (till version 4.x) as OS for
guests. The host is always x86_64, also with a RedHat like OS.
I''m moving now to the latest 5.4 OS version.
I have a new AMD server (CentOS x86_64 5.4) with xen up and running from
the standard repos, thus version 3.something
After successfully creating my domU pristine image (CentOS 54 x86_64 /
or x86; the image domU''s work just great), I''m simply not able
to boot
successfully the LV domU originated from the image.
I tried both in intel/AMD servers with x86 or x86_64 paravirt LV
domU''s,
and having problems during boot:
restorecon: error while loading shared libraries: libc.so.6: cannot open
shared object file: No such file or directory
Can someone shed some light on this?
Part II
+++++
I also tryed instead of creating a pristine image file, install the
pristine domU directly into a LV based. But, how do I mount the LV to
edit configuration files inside of it? Because now there is a partition
table inside the domU, and I don''t know how to handle with it. Any link
on how to do it?
Many thanks,
N.
P.S. Some more detailed info about dom0, xen log, xm info ...
dom0 specs

Re: [Xen-users] Dump an image based domU to a logical volume
Dear Simon, Thanks. I just found out that ... kpartx tool is also able to work with logical volumes (I thought that it was meant only for file based stuff like images). Thus, even if the LV based domU has several partitions (in the same LV) they can be accessed individually and file edition is possible for fine configuration of the domU if needed. Cheers, N.

RE: [Xen-users] Dump an image based domU to a logical volume
> > Easier with kpartx. > See: http://wiki.xensource.com/xenwiki/XenCommonProblems >In my experience, losetup with an offset is safer for some ntfs operations than kpartx. Kpartx seems to get some of the metrics wrong and has toasted my ntfs filesystems before.
