Multiple resize problem on XenSever6

Asked by Giuseppe Civitella

Hi all,

I'm experiencing the following problem doing a short term multiple
resize test using XenServer6 as hypervisor.
On first resize everything works as expected. If I do another resize a
few minutes later, I receive an error about "VHD coalesce
attempts exceeded" on destination host.
Here's an extract from nova-compute.log:

On the hypervisor's /var/log/SMlog I can find errors like this:
http://paste.openstack.org/show/3369/

Can someone give me some advice about this issue?
Is it something related to the hypervisor? Do I need to wait longer
between a resize an the other?

Thanks a lot
Giuseppe

I've got problems runningu multiple resize on XenServer5 too.
Can someone confirm it is possible to resize the same machine more times in a short time interval?

Thanks

I can confirm I'm not having the problem anymore.
My env is XenServer6, nova Essex (milestone 2 and 3) and images built
not using xenconverter's OVA.
A huge thanks to Tod Deshane and Paul Voccio for their help and patience:
they can barely imagine how much I owe them :-)

Regards
Giuseppe
