Open Stack

Hello all,

I just want to know in which way is OpenStack going with XenServer/XCP 
support. I want to create small cloud but in testing I faced with many 
issues and it looks like OpenStack + XenServer is not usable for production.
Some issues:

- Can't aggregate hosts. (After patch it is going to work, but in 
XenServer second host's PV domU nova-compute won't start anyway 
https://ask.openstack.org/en/question/8392/aggregate-hosts/)
- Not normal shared storage support. Isn't possible to resize instances 
with shared storage.
- Shared storage is important, without shared storage XenServer can't 
create aggregate zone (Resource pool) and use live migration.

I don't know, maybe this things is for someone less important, but for 
me it is "must have". Or OpenStack community recommend to use XenServer 
without resource pools and shared storages? For migration can use 
storage live migration which is slow in a way of emergancy maintaince 
and additionl IOPS on storages.
Maybe someone can share his experiance creating cloud with OpenStack + 
XenServer?

Thanks.
