Open Stack

Hi Yungho,

The use of aggregates with XenServer pools in this fashion is not very well tested – unless you absolutely need shared storage (i.e. live storage migration is not sufficient) then we’d advise you don’t use aggregates with pools like this.

This was a known regression at release time and it is fixed now.

Bob

Nova-compute the first successful connection MASTER XENSERVER

I discover, that I can't set up nova-compute on "second host" in XenServer pool
which is created by XenServer (without OpenStack aggregate), error is same. To
master host nova-compute connects successfully. I tested this in two different
XenServer 6.2 pools.
Is there some solution how can start to work "second host's" nova-computes?

The second nova-compute connected SLAVE XENSERVER following error LOG
