Hi,
I am having problems getting a domain to start using "xm create". I am running unstable, I pulled today and rebuilt, installed and rebooted. (I also have a few loader patches, posted earlier).

I am able to start a domain using VM Tools and the following script:
  dom=`vm-create`
  vm-memory -m $dom 64m
  vm-memory -i $dom 64m
  vm-build.linux $dom /root/9hello noargs
  vm-pause -u $dom

I'm using the following config file in /etc/xen/hello:
  name = 'Hello'
  kernel = '/root/9hello'
  memory = 64
  extra='''cmdline'''

Running "xm create hello" gives:
  Using config file "/etc/xen/hello".
  Error: Error creating domain: (12, 'Cannot allocate memory')
  # xm list
  Name              Id  Mem(MB)  CPU VCPU(s)  State  Time(s)  Console
  Domain-0           0      123    0      1   r----     91.1
  Domain-7           7       51    0      1   --p--      0.0

There is no useful diagnostic information in /var/log/xend*.
Where should I be looking?  Is there a useful way to trace and
debug xend?
