Hi, If I understand your request correctly, say you have two storage backends with different QoS and you want to use both of them in your OpenStack/XCP deployment, what you can do is:
1) create SR1 for XCP1 that maps to storage array at QoS1 1a) configure the compute domU for XCP1 to point to SR1, by specifying sr_matching_filter in your nova.conf accordingly. 2) create SR2 for XCP2 that maps to storage array at QoS2 2a) configure the compute domU for XCP2 to point to SR2, by specifying sr_matching_filter in your nova.conf accordingly. You can find more details here: http://wiki.openstack.org/XenServer/NovaFlags Obviously this can be extended to multiple nodes; then you can use the CLI/scheduler filters to redirect the create request to the right host. That is one way, but there are a few others like or compute extra capabilities (Essex) or general host aggregates (Folsom+) Hope this helps, Armando On Fri, Nov 2, 2012 at 9:34 AM, Egoitz Aurrekoetxea Aurre < ego...@ramattack.net> wrote: > Or unless… If I had to use forcibly the same storage…. for all vm > provisioned in a single nova-compute…. is it anyway of saying Openstack to > create a vm in a nova-compute or another one… depending on the storage > attached to the nova-compute's dom0?? > > > El 02/11/2012, a las 10:25, Egoitz Aurrekoetxea Aurre < > ego...@ramattack.net> escribió: > > > Good morning, > > > > Perhaps I have not explained properly….
