Open Stack

Hi Afef,

There was a regression in Icehouse that broke XenAPI aggregates.  This has been fixed in Juno, however we would recommend you use live migrate with block migration (using XCP 1.6 or XenServer 6.2 – which is Free as well now, see http://lists.openstack.org/pipermail/openstack-dev/2013-September/014556.html).

Thanks,

Bob

Subject: [openstack-dev] Devstack (icehouse) - XCP - enable live migration

Hi all,

I have installed the latest release of openstack (icehouse) via devstack.
I use XCP and would like to activate the "live migration" functionality. Therefore, I tried to set up the pool with creating "host aggregate".
After adding the slave compute, nova-compute does not want to start any more and shows the following error. Could you please help me to fix this issue.
