[Xen-devel] daemon to monitor 'xm dmesg'

["James Harper" <james.harper@xxxxxxxxxxxxxxxx>]

Is there a way to put xen's logs into a file in dom0? Eg
/var/log/xen/hypervisor.log or something like that?

I just did an 'xm dmesg' and saw this:

(XEN) p2m_pod_demand_populate: Out of populate-on-demand memory!

(XEN) Domain 72 (vcpu#0) crashed on cpu#1:

But I'm not sure exactly when it happened, other than it happened to
domain 72 whenever that was created.

Thanks

James
