[PVE-User] HA feature

I know there is no release date planned for Proxmox 2 (especially for 
the HA feature).
However, the feature i really want to use is to recover as soon as 
possible, but not automatically, all the VMs which resided
on a fail node on an available node in the cluster.

I use AoE shared storage, so, all VMs disks are known from proxmox slaves.
I'm wondering and testing if i synchronise /etc/qemu-server/*.conf files 
from master to slaves, would be a good workaround.

On each slave, i plan to set a crontab task as this :
* * * * * rsync -e ssh -au master:/etc/qemu-server/ /etc/qemu-server/

With this, the slaves now know all the VMs created on the master. With 
this workaround, you have now to create the VMs on
the master and one minute after, the slaves are aware of the new VM.

The small problem is the state (online/offline) of VMs between master 
and slaves are not synchronised (network conflicts could occur).
So, you have to be carefully about that.

What do you think about this workaround ? Any improvement of it ?
