I'm not certain why, but self.channel for dom0 is not intialized. I can
see this when testing dom0 vcpu-hotplug with the attached patch applied.
root@bebop:/var/log # xm list
Name Id Mem(MB) CPU VCPU(s) State Time(s) Console
Domain-0 0 507 0 2 r---- 20.0
root@bebop:/var/log # xm list -v
Name Id VCPU CPU CPUMAP
Domain-0 0 0 0 0x3
Domain-0 0 1 1 0x3
root@bebop:/var/log # xm vcpu-hotplug 0 1 0
Traceback (most recent call last):
File "/usr/lib/python2.4/logging/handlers.py", line 62, in emit
if self.shouldRollover(record):
File "/usr/lib/python2.4/logging/handlers.py", line 132, in shouldRollover
self.stream.seek(0, 2) #due to non-posix-compliant Windows feature
ValueError: I/O operation on closed file
[xend] ERROR (XendDomainInfo:975) self.channel is not valid
Putting a call to self.create_channel() if not self.channel works, but it is a
hack.
I've put this in bug #101
