I installed devstack on top of xenserver. Now I want to add a ubuntu image to openstack. I downloaded qcow2 image from here and used the guideline here to convert the image to vhd format and added to openstack using glance.

But when I start the instance, it got shut-off automatically. When I try to restart the instance in Xensenver, it got stuck at the messages:

[    1.612617] EXT4-fs (xvda1): mounted filesystem with ordered data mode. Opts: (null)
[    2.245259] EXT4-fs (xvda1): re-mounted. Opts: (null)

One thing to mention is I successfully added a cirros image to xenserver using the steps above, So what's the problem here? Could any one give any suggestions?

Thanks in advance!

What does your nova-compute debug log say ?

I've not seen this issue before, but can I suggest you enable serial logging of your Ubuntu VM? Make sure your kernel boot line has console=ttyS0 and set up Xen to log the serial consoles - see http://support.citrix.com/article/CTX...

I think that re-mounting during boot is perfectly normal as Linux mounts as read-only first, then mounts to read-write during the boot process.

One possibility is that Ubuntu may be referring to the root partition as 'sda', whereas in Xen it may show up as sda without paravirtualised drivers of xvda with them. The best way to refer to a disk is by it's UUID
