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_crash called from p2m.c:1079
(XEN) Domain 72 (vcpu#0) crashed on cpu#1:

(XEN) ds: 0023 es: 0023 fs: 003b gs: 0000 ss: 0023 cs: 001b
But I'm not sure exactly when it happened, other than it happened to
domain 72 whenever that was created.
Thanks

And then to where will the log be directed to? where will it be
located on the HD?

Has anyone else noticed repeat messages in the log file after enabling
hypervisor logging? It seems like whenever a few messages are logged
to 'xm dmesg' the entire contents of 'xm dmesg' are appended to
hypervisor.log.
