My VM templates are <4GB in size, and when I finish cloning them into a Virtual Machine, they are still <4GB in size:
My ESXi machine is attached to a NAS with a 1Gbps link, the vCenter machine is running on bare metal, also attached via 1Gbps to the ESXi and NAS. If I initiate cloning the template to a VM and pop onto the NAS to check its network usage with
vnstat -l, I see the 1Gbps pipe being fully used:
root@nas:~# vnstat -l Monitoring eth0... (press CTRL-C to stop) rx: 5.71 Mbit/s 7085 p/s tx: 958.14 Mbit/s 81384 p/s
Despite this, cloning takes around 6-8 minutes:
Without doing too heavy of math, it would appear that this should be significantly shorter. Like < 1 minute.
What could I be doing better to speed up this provisioning time?
