I executed following command
qemu-img convert -c -f raw -O qcow2 /dev/nintendo/lvm2 /root/lvm2.img
qemu-img: error while compressing sector 22151296
what does this mean and how can I get rid of this and take the backup?
I am on Ubuntu 10.04 server 64 bit.

extra work: creating an LVM and making a filesystem populating that
filesystem with rsync backup and then copying xml
files and then some how booting from this one.

I am trying to mount an LVM
mount /dev/nintendo/backupos /mnt/backup/
mount: /dev/mapper/nintendo-backupos already mounted or /mnt/backup/ busy
where as if I do umount /mnt/backup
then
umount: /mnt/backup/: not mounted
So what might be wrong?

Well, it's possible that you have it mounted in another namespace.
Can you provide output of:
1. ls -l /mnt/backup
(make sure that directory exists :)
2. ls -l /dev/mapper
3. cat /proc/self/mountinfo
4. cat /proc/self/mounts
5. cat /proc/1/mountinfo
6. cat /proc/1/mounts
thanks,
-serge
Q
mount output is
/dev/sda1 on / type ext4 (rw,errors=remount-ro)
proc on /proc type proc (rw,noexec,nosuid,nodev)
none on /sys type sysfs (rw,noexec,nosuid,nodev)
none on /sys/fs/fuse/connections type fusectl (rw)
none on /sys/kernel/debug type debugfs (rw)
none on /sys/kernel/security type security
I am not clear if I am doing the correct thing so some one point me to
the correct thing.
I created a snapshot Volume of an LVM which holded a guest OS.
I mounted this snapshot and using I took a backup on a server
connected remotely.
Now on Server A I created a new LVM this server A is different

I am searching for some information.
I used virt-manager to create 4 guest OS on KVM.

Is is some how possible guest running on server A can be transferred to B
so that I can run it and do not have to do a
