i am trying to create a domain using libvirt 0.9.4 python api and i can't find any information on how to use the libvirt python api with linux logical volumes
http://libvirt.org/guide/html-single/#Application_Development_Guide-Device_Config-Disks is TBD

i figured out that i need to use defineXML to create a domain, however for the disk part in the xml, i am not sure if i need to create the LVM first, or just specify the LVM path and libvirt will create the lvm for me and stick the domain on the lvm

    <disk type='block' device='disk'>
      <driver name='qemu' type='raw' cache='none' io='native'/>
      <source dev='/dev/vg001/myhost.blah.com'/>
      <target dev='hda' bus='ide'/>

/usr/lib64/python2.6/site-packages/libvirt.py has:

        ret = libvirtmod.virStorageVolCreateXML(self._o, xmldesc, flags)
        if ret is None:raise libvirtError('virStorageVolCreateXML() failed', pool=self)
        __tmp = virStorageVol(self, _obj=ret)
        return __tmp

however i don't know the xml format for storage vol
