Ok, this almost seems too easy ... :)
What I was trying to avoid was more tweaking of ON files when installing VDC.
The issue I see is that each time someone upgraded ON, they will potentially
have a chain of
small patches to apply ... if I supply a few small patches based on "if <vdc
installed> - do something extra"
would you include these in the stock scripts??

Hi Gareth
As the migrate script can be easily updated we do not provide any hook for
that. I'd go to kvm/migrate, and do a simple if [ $? ... after the virsh
command to kill the cache on the target host.
Cheers

Hi,
I implemented live migration for the VDC driver a few weeks back and on the
whole it seems to work
quite well. The "premigrate" script creates a cache instance on the target
server and puts the source
cache into proxy mode, then the "postmigrate" script kills the original cache
instance.
Problem :: if the migration fails, I'm left with a running cache on both the
source and target servers, with
the source cache in proxy mode. I have a 1-line CLI command to revert the
issue, but I need to hook into
the system in order to call it.
How to do I do this, I guess effectively I need something like
"postmigrate_fail" .. ???
