Thread-topic: [Xen-API] Release date for XCP 1.0 stable
I would stick with XCP if the issue was solved. 
As a suggestion I would also test what will happen on a power failure when 
multiple VMs are actually doing intensive I/O (usually data loss/complete file 
system corruption occurs)
Other than that, it all depends on your needs. Do you manage your Xen 4 with 
Debian manually ? (without xapi/other tools).

Now I'm in a quandary?

We are pushing out a new infrastructure with 6 hosts and a san next month. We 
have been working with xcp but decided to drop it because of vdi lock up 
issues. We tested power outages with our xcp host and iscsi san and weren't 
happy with the results i.e the locked vdi issue.

So we have moved over to Debian 6 with xen 4 and begun testing. We plan to have 
a crack at setting up clvm later in the week to test live migrations and our 
iscsi san.

Then I get your email saying that vdi lockups have been addressed in XCP 1.0 
and I'm wondering what the best way forward is?

I know there's not a right answer but if anyone had any thoughts on what is the 
best path I would appreciate them.

I think that's very unlikely at this stage. I don't think we've actually got 
any IB hardware, so we'd have a job testing it. If you have the hardware and 
the time to test it, it might be something that could go into the next release
