[ale] [OT] VMWare learning environment?

There's some export capabilities that I can't recall the name of right
now (it'll wake me at 2am).
AH! virt-v2v!
I used that some time back to capture VMs off a vmware esx setup and
pull them over to ovirt. It requires the VM be powered down. Easier way
is to make a snapshot, convert to a new VM and pull that, then rsync
from old to new. For some reason people think uptime matters and I'm
supposed to care about it (on systems that have not been rebooted in
300+ days - security warts and all - can't "afford" the downtime -
<sigh>).

Every time you stop a school, you will have to build a jail. What you
gain at one end you lose at the other. It's like feeding a dog on his
own tail. It won't fatten the dog.
