Re: NovaCompute on XenServer6
Hi all,
I did some further testing and found something that works for me as a
workaround.
Since I was getting an error like this on XE6:
[20111003T08:57:36.775Z|debug|xe1|398170 inet-RPC|VDI.resize_online
R:3fa63f98fab0|audit] VDI.resize_online: VDI =
'2e79ace3-5cb3-418c-9aad-58faf218c09e'; size = 42949672960
I had a look at the XenServer Administrator guide
(http://docs.vmd.citrix.com/XenServer/6.0.0/1.0/en_gb/reference.html#cli-xe-commands_vdi)
and found vdi-resize as only method to resize a VDI.
At row 625 of nova/virt/xenapi/vmops.py I changed:
self._session.call_xenapi('VDI.resize_online', vdi_ref,
to
self._session.call_xenapi('VDI.resize', vdi_ref,
Now I'm able to resize a VM on XS6 but, since I'm not an XS expert,
I'd appreciate if someone can confirm the second xenapi call as a
valid solution.
Thanks a lot
Giuseppe
