Hi. I have a domU that refuses to start up. It reports an error allocating memory. There appears to be sufficient memory in dom0 as well as on the host. I can restart other domUs no problem.

To resolve the issue I'm having to restart the whole server. Which is a bit disruptive.

How many domains are already running? Xen's own private heap can be exhausted even when there is guest memory available.

I have 41 domains running (including dom0).

Is there a way to help avoid Xen's private heap getting exhausted? e.g. increase the memory allocated to dom0? Or a setting change? or?
