[Xen-API] Shutdown race condition with heartbeat/pacemaker

[Andrew Eross <eross@xxxxxxxxxxxx>]

Hey guys,

I run into a problem with my pacemaker managed VM power-off competing with the built-in domU shutdown script (/opt/xensource/libexec/shutdown).

It's not a problem for power-on, as that's controlled by an other_config flag: auto_poweron

I'd like to suggest adding a similar auto_poweroff flag to allow controlling shutdown when desired.

e.g. to set this on a VM:

xe vm-param-set other-config:auto_poweroff=false uuid=$UUID

I did this myself and modified the shutdown script to look for this flag and ignore those VMs.

See attached patch, also available here: http://download.locatrix.com/pacemaker/shutdown.patch

cd /opt/xensource/libexec

cp shutdown shutdown.orig

patch -p1 < shutdown.patch

I was wondering if the xenserver/xcp maintainers would consider including this (or what they think about the idea)?

Cheers,

Andrew
