Re: [Xen-users] PANIC domain 0

Must be a different problem.

We had similar Dom 0 panics.

Your problem could be almost anything, though someone how knows
more about Xen might be able to help more than I.

Hi Tom.

I looked for this message for my domains and doesn't appears.
By the way, panic happened in domU, and not in dom0.


Is a kernel bug ???

I am worried because today it has returned to happen.

Thanks in advanced.

Take a look in the Dom0 and DomU syslogs and see if you see

memory squeeze in netback driver.

If so, there's a kernel startup configuration change you need to make.
