[Xen-users] XCP 0.5.0 bug, XCCS 0.5.5.1 impacted

[Vern Burke <vburke@xxxxxxxx>]

Greetings all:
   In the process of building VMs on my XCP 0.5.0 pool, I accidently 
built one with an outdate guest agent (0.1.1). This out of date guest 
agent caused the host evacuate function in XCCS to misfire, since xe 
host-get-vms-which-prevent-evacuation in 0.5.0 does not show the VM 
can't be evacuated, which it should. This does not effect the VM migrate 
function, since XCCS does its own internal checking in that case.
Workaround:

If an XCCS host evacuate fails to evacuate all VMs, check the VMs on 
that host for out of date PV driver/guest agent and update or shut down
the VM.

Fix:

Update 0.5.5.2 will release Friday to fully implement internal checking 
for out of date PV drivers/guest agent and discontinue the use of the 
malfunctioning host-get-vms-which-prevent-execution function.
