[one-users] VM's are going to pending state though enough resources

Hi Bathina,
Your VM template is requesting 1 physical CPU for exclusive use, and your
host has only 4 available: TCPU is the total percentage of CPU reported by
the host.
That's why your VMs stay in pending state, because the scheduler sees that
your host doesn't have enough CPU resources for the next ones.
Try commenting the "CPU = 1" line in the template. Please note that the CPU
is the physical host's CPU requested, and is different from the number of
Virtual CPUs the guest OS will see. Take a look at the VM template
documentation [1].
Regards,
Carlos
