Re: [Xen-devel] Xen 3.0.1 Error creating domain: (12, 'Cannot allocate memory')

Unfortunately not, but I'd expect you to be able to create more than 41 domains. When we've tested this we've been able to create about double that number.
We've hit this before. I'm not sure if it was on the same host server or not. Is there any other information we can collect that would be useful resolving this?

Or are there any actions we can try to see if we can fix the issue (other than a reboot of the host server which seems to do the job, but is obviously a bit disruptive to other domUs).

I just added a 'm' debug key to the unstable repository. If you have a serial line on the offending machine and apply that patch to your tree, you can get free-memory infomation when the failure happens and confirm that the Xen heap is depleted.
