I had a customer who tried to use this script, but it didn't work. I
made some modifications to the control script. Additionally, the
customer wanted to start/stop multiple machines. The solution
implemented makes the Resource Agent a simple script -- vmstart_all --
that makes multiple calls to vmstart in order to start/stop the virtual
machines. Here is vmstart_all:
#!/bin/bash
VMSTARTDIR="/etc/ha.d/resource.d"
# Start up multiple virtual machines
# enter one per line in the following format:
# $VMSTARTDIR/vmstart $1 directoryname
#
# where directoryname is the name of the
# directory that contains a .vmx file
$VMSTARTDIR/vmstart $1 vm1
$VMSTARTDIR/vmstart $1 vm2
And here's the patch for vmstart:
--- vmstart.20081114 2008-12-18 11:02:30.000000000 -0500
+++ vmstart 2008-12-18 11:12:45.000000000 -0500
