Re: [Xen-devel] [PATCH] PV framebuffer

[Markus Armbruster <armbru@xxxxxxxxxx>]

Hi Steven,

I had a look at your changes and started to backport them to versions
we use.  I might have broken something, but before I go hunting for
that, could you please try two little things for me in your version,
to make sure its okay in your tree?

1. Does xm restore work for you?  I got the following in xend.log:

[2006-12-04 20:34:54 xend 3507] ERROR (XendDomain:268) Restore failed
Traceback (most recent call last):
  File "/usr/lib/python2.4/site-packages/xen/xend/XendDomain.py", line 263, in 
domain_restore_fd
    return XendCheckpoint.restore(self, fd)
  File "/usr/lib/python2.4/site-packages/xen/xend/XendCheckpoint.py", line 134, 
in restore
    dominfo = xd.restore_(vmconfig)
  File "/usr/lib/python2.4/site-packages/xen/xend/XendDomain.py", line 288, in 
restore_
    dominfo = XendDomainInfo.restore(config)
  File "/usr/lib/python2.4/site-packages/xen/xend/XendDomainInfo.py", line 271, 
in restore
    vm.createDevices()
  File "/usr/lib/python2.4/site-packages/xen/xend/XendDomainInfo.py", line 
1515, in createDevices
    self.createDevice(n, c)
  File "/usr/lib/python2.4/site-packages/xen/xend/XendDomainInfo.py", line 
1086, in createDevice
    return self.getDeviceController(deviceClass).createDevice(devconfig)
  File "/usr/lib/python2.4/site-packages/xen/xend/server/vfbif.py", line 64, in 
createDevice
    raise VmError('Unknown vfb type %s (%s)' % (t, repr(config)))
VmError: Unknown vfb type None (['vfb', ['backend', '0']])

2. My xm shutdown spits this:

[2006-12-04 20:33:37 xend.XendDomainInfo 3507] ERROR (XendDomainInfo:1382) 
XendDomainInfo.cleanup: image.destroy() failed.
Traceback (most recent call last):
  File "/usr/lib/python2.4/site-packages/xen/xend/XendDomainInfo.py", line 
1380, in cleanupDomain
    self.image.destroy()
  File "/usr/lib/python2.4/site-packages/xen/xend/image.py", line 210, in 
destroy
    if not self.pid:
AttributeError: LinuxImageHandler instance has no attribute 'pid'
