This is what I came up with so far:

#!/bin/bash
# see why this is so at http://www.linux-ha.org/HeartbeatResourceAgent
usage()
{
       echo "usage: $0 VMname start|stop|status"
       exit 1
}
[ $# -ne 2 ] && usage;
#currently, we plan to have only A and B
if [ "$1" != "A" -a "$1" != "B" ]
then
       echo "Invalid VM name (only A or B configured at this point)"
       exit 1
fi
#path to VM vmx file
VMPATH="/var/lib/vmware/vm$1/vm$1.vmx"
STATE="`vmware-cmd -q "$VMPATH" getstate`"
HB="`vmware-cmd -q "$VMPATH" getheartbeat`"
case "$2" in
       start)
               if [ "$STATE" = "off" ]
               then
                       vmware-cmd -q "$VMPATH" start
                       RETVAL=$?
               else
                       RETVAL=0
               fi
               ;;
       stop)
               if [ "$STATE" = "on" ]
