Comment 5 for bug 862653

Hi Glen,

It appears that the vhd_util resize operation doesn't like to work with some OVA images (ones not created on XenServer?).

https://github.com/xen-org/blktap/blob/master/vhd/lib/vhd-util-resize.c#L1052

In my case I think I was using a small Debian Squeeze image that I converted to OVA format using xenconvert (months ago). The image was fine and it booted w/ nova before this commit. Additionally my initial image was also resizable after it booted fully.

---

The work around for me was to manually create a new OVA image by hand using the VHD of the booted instance on XenServer. Creating a tar of that VHD with an empty manifest.ovf makes this issue go away.

My guess is that others might hit this same issue when using nova w/ XenServer. Specifically anyone booting an OVA image which wasn't created directly from a XenServer dom0.

Hope that helps. I didn't have time to track it any further.

Dan
