[ClusterLabs] timeout for stop VirtualDomain running Windows 7

[Lentes, Bernd]

Hi,

i have a VirtualDomian resource running a Windows 7 client. This is the respective configuration:

primitive prim_vm_servers_alive VirtualDomain \
        params config="/var/lib/libvirt/images/xml/Server_Monitoring.xml" \
        params hypervisor="qemu:///system" \
        params migration_transport=ssh \
        params autoset_utilization_cpu=false \
        params autoset_utilization_hv_memory=false \
        op start interval=0 timeout=120 \
        op stop interval=0 timeout=130 \
        op monitor interval=30 timeout=30 \
        op migrate_from interval=0 timeout=180 \
        op migrate_to interval=0 timeout=190 \
        meta allow-migrate=true target-role=Started is-managed=true

The timeout for the stop operation is 130 seconds. But our windows 7 clients, as most do, install updates from time to time .
And then a shutdown can take 10 or 20 minutes or even longer.
If the timeout isn't as long as the installation of the updates takes then the vm is forced off. With all possible negative consequences.
But on the other hand i don't like to set a timeout of eg. 20 minutes, which may still not be enough in some circumstances, but is much too long
if the guest doesn't install updates.

Any ideas ?

Thanks.


Bernd
