The contents of the qemu log are:
domid: 5
qemu: the number of cpus is 1
Watching /local/domain/5/logdirty/next-active
Watching /local/domain/0/device-model/5/command
qemu: could not open serial device 'none'

Note that the qemu-dm process is listed as 'defunct' in ps.

One interesting line from the xend.log that I don't know how to 
interpret is:
[2010-03-29 21:03:53 xend.XendDomainInfo 3186] DEBUG 
(XendDomainInfo:633) Checking for duplicate for uname: 
/dev/SystemsVG/Belldandy [phy:/dev/SystemsVG/Belldandy], dev: hda:disk,
mode: w
[2010-03-29 21:03:53 xend 3186] DEBUG (blkif:27) exception looking up 
device number for hda:disk: [Errno 2] No such file or directory: 

Not sure if it means anything but thoughts appreciated.  This is **not** 
the last line in the log.
