Clon Hdd for EXSI

Before proceed, first you must enable SSH in EXSi

then you can transfer your own ready make .vmdk by scp or winscp into EXSi

but for myself, i make a standard template in EXSi so i can easily deploy other server in future.

create a new VM but skip the hdd creation 

SSH into EXSi and use this command

# vmkfstools -i <input.vmdk> <output.vmdk>

then edit the VM, add hdd into it but click
use an existing virtual disk and select the newly cron disk

usually the location of the vm is at 

/vmfs/volumes/<random.number>/

so you need to identify out the location

if you re-cron back to the same EXSi server, there might be network problem with the newly cron server because the network card MAC will be different. so you need to go to
/etc/udev/rules.d/70-persistent-net.rules to update your MAC address
you just need to exchange the eth0 with the eth1 and eth1 to eth0
