Hi,
I have found problems with xendomains service, when I wanted to start
all the virtual machines. So, I have written a service, which services
the purpose of xendomains. Hope, this may be useful.
and here are few details
if we want to run only one particular virtual machine
then we will run as
./resourceagent vm1{virtual machine}
and suppose if we want to run all the virtual machine,
then simply
./resourceagent
And also this code can be treated as ocf or lsb script
I am attaching as well as copying the code.
#!/bin/sh
VMCONFIG="/etc/xen"
vm=$2
retval=0
- Ignored:
usage()
{
echo "The valid options are"
echo "start|stop|status|monitor|meta-data"
}
virtualmachine_meta_data()
{
cat <<END
