Persistent static routes

Hi,

I have a problem configuring my network on the RHEV (3.0 beta) hypervisors. For our storage network I need to add a route which should survive reboots.

Normally one would place a route- file in /etc/sysconfig/network-scripts and be done with it,  however this does not seems to survive reboots on RHEVH machines.

What would be the preferred method of doing this?
