Hi,

This is interesting:
2012-12-03 14:38:25 ERROR nova.compute.manager [req-3e393b4e-d0ed-430f-b0cc-53a9167e6666 afef cep4cma] [instance: d3dba21b-3877-4da3-a2ab-8128f8515573] VHD coalesce attempts exceeded (5), giving up.... Setting instance vm_state to ERROR

Is it possible to get the logs from your XenServer host to tell us what was going wrong when this happened?

What is the version of your server, and I am assuming the VM disks are on an EXT3 SR?

Subject: [Openstack] resizing instance fails

Hi all,

when I try to resize a running instance, I get this error:
Is there any way to solve it?
