Essex stable running on Xenserver: DEVICE_DETACH_REJECTED errors during stress test
Hi all,
I'm seeing multiple DEVICE_DETACH_REJECTED errors in my nova-compute's logs when running a deploy's stress test. I run a few nova-compute vms (ubuntu 10.04 on kernel 3.2.7) on some xenserver6 nodes. The openstack's version I was running is Essex stable. While I was able to deploy correctly a single vm on every node, if I did try to schedule about five virtual machine's deploy per node, I received errors like those reported here:

I did rollback to essex4 running on same xenserver hosts and on same nova-compute virtual machine. the errors vanished.
