==Reload vmx file==
vim-cmd vmsvc/reload Vmid

==vim-cmd==
vim-cmd vmsvc/getallvms Get all vm:s.
vim-cmd vmsvc/get.config 1835 Get info about vm.
vim-cmd vmsvc/power.on Start vm.
vim-cmd vmsvc/power.off Stop vm.
vim-cmd hostsvc/hosthardware Get info about underlying hardware. | grep numCpu (to get number of cpu:s.
vim-cmd vmsvc/destroy 1948 Delete vm

=get info about vim and if it is powered on=
vim-cmd vmsvc/getallvms | grep -v Vmid | while read ID NAME ; do echo $(vim-cmd vmsvc/power.getstate $ID| grep -v ^Retrieved) $NAME ; done | cut -c -180

==To power on a virtual machine from the command line:==
# List the inventory ID of the virtual machine with the command:
vim-cmd vmsvc/getallvms
# Check the power state of the virtual machine with the command:
vim-cmd vmsvc/power.getstate <vmid>
# Power-on the virtual machine with the command:
vim-cmd vmsvc/power.on <vmid>
