driver domains broken?

[Alex Williamson <alex.williamson@hp.com>]

   Has anyone tried driver domains with all the new Xen-API code?  It
seems unhappy parsing the PCI device.  I get something like this in
xend.log using current xen-unstable.hg:

[2006-11-14 15:31:01 xend.XendDomainInfo 6903] DEBUG (__init__:1072) XendDomainInfo.create(['vm', ['name', 'debianDD'], ['memory', 2048], ['vcpus', 2], ['on_xend_start', 'ignore'], ['on_xend_stop', 'ignore'], ['image', ['linux', ['kernel', '/boot/xenlinuz'], ['root', '/dev/hda1 ro'], ['args', 'console=tty1']]], ['device', ['vbd', ['uname', 'phy:/dev/VBDs/debianDD'], ['dev', 'hda1'], ['mode', 'w']]], ['device', ['pci', ['dev', ['domain', '0x0000'], ['bus', '0x01'], ['slot', '0x02'], ['func', '0x1']]]]])

Sorry if I missed a change in specifying driver domains.  Thanks,
