[vdsm] Readonly leases error in vdsm log

[Deepak C Shetty]

Hello,
I am creating a VM using vdsm standalone script and facing issues 
when i add cdrom and make it boot from cdrom.




vdsOK(
s.create(dict(vmId=vmId,
  drives=[dict(poolID=spUUID, domainID=sdUUID, 
imageID=imgUUID, volumeID=volUUID)],

  memSize=256,
  display="vnc",
  vmName="vm-backed-by-gluster",
  cdrom="/home/deepakcs/Fedora-16-x86_64-Live-Desktop.iso",
  boot="d",
  custom={"dpktry":1},
 )
)

When i added cdrom= and boot= lines and ran, i see the below in vdsm.log

Traceback (most recent call last):
  File "/usr/share/vdsm/vm.py", line 570, in _startUnderlyingVm

It looks like its trying to use the cdrom disk device as a disk lease, 
hence complaining?

But the libvirt xml has  tags which looks liek this...


file="/rhev/data-center/98fc6cd9-d857-4735-bc7a-59a289bc0f55/01400276-e3c8-44d9-8353-924ab2183af2/images/95c9f6a4-def1-4300-baf6-db884dc8ccca/9d62e802-859e-4381-8029-7be5a6b1de26"/>


95c9f6a4-def1-4300-baf6-db884dc8ccca
type="raw"/>



startupPolicy="optional"/>





Any idea why it throws "Readonly leases are not supported" ?

thanx,
deepak
