Hi,
i would like to use qcow2-sparse-images which point to a backup-file.
After reading this: http://wiki.xensource.com/xenwiki/DmUserspace i
figured out that this feature seems to be unsupported by the ubuntu
8.04 LTS kernel and xen-3.2.1.
Is this a ubuntu-specific problem, or is it solved in Suse, Red Hat,
XenSource, whatever?
When i try to block-attach it, xm displays no error, but the device is
not created.
# xm block-attach 0 tap:qcow:/var/xen/domains/dapper10/test.img /dev/sdh1 w 0
# mount /dev/sdh1 /mnt/test/
mount: special device /dev/sdh1 does not exist
In the config file
''tap:qcow:/var/xen/domains/dapper10/test.img,sda2,w'',
--> test.img is in use. And i thought there is no /dev/sdh1?
xm block-detach ...
Now the VM boots, but stucks after kernel waiting for
root-filesystem... In my understanding, test.img references to
disk.img, which is a raw-image, and should use on the first boot every
block from disk.img including the fs-type, etc.
# less test.img
shows the correct reference to disk.img, but it don''t work either.
Any ideas?
Regards
Fabian
