How exactly does moving from an esx server (with adjustable vcpu's) to an esx 
server (with adjustable vcpu's) solve anything?

Your general plan sounds decent and, as other have mentioned, your concerns 
could probably be overcome with a pre-sysprep snapshot. But, why not go a step 
further and create a copy of the .vmdk file and try the migration with that 
while the original sits safely turned off?

Subject: OT - converting a VMware VM back to a physical box

So I've got a request that is confusing me.


Environment: 6 host EX 4.1 U1 cluster. VM in question - Win2003 Enterprise, 32 
bit


My boss tells me that I need to convert this from a VM back onto a physical 
machine - for licensing reasons, this needs to be a physical box, apparently.


So here's the big rub ... this VM is one of those mission-critical VMs. 
Ordinarily, what I might have done is do a sysprep of the VM, and - before 
shutting it down - do a full backup using EMC Networker. Then, I would do a BMR 
(Bare Metal Recovery) of Windows on the new physical hardware. (when doing a 
BMR, you install Windows and your backup client on the new hardware. Then do a 
full restore, using the backup client, of everything except the backup client 
program files). That way, after the reboot at the end of the BMR, sysprep would 
run, find the new disk controller drivers, etc, and not blue screen with 
inaccessible boot device errors.


However, my boss has vetoed that idea, since we can't take any chances with the 
VM perhaps not working after the sysprep. If that BMR doesn't work, then I 
would need to turn the VM back on. and we have no guarantees that it would 
continue to work the same after the sysprep, etc.


So my hands are tied that way.


Then I thought - well, we could still do a BMR, but without the sysprep first. 
Just do a regular full backup, and then the BMR to the physical box. And if it 
fails to boot, we would (maybe) do a Windows repair installation, using the 
drivers for whatever disk controllers are in the physical box. Doing the BMR 
won't overwrite any drives that would be installed for the clean first-time 
Windows install, and so they'd still be there for the repair installation to 
find. That way, either the physical box would work, and I'd leave the VM 
powered off, or the physical box would fail, and I would power the VM back up.


So: any hints on how I can take this VM, and put it on a new physical box, make 
it work .. and still get the VM to boot afterwards, in case the conversion to 
physical did not work? Basically, I need the reverse of the P2V converter, 
where - if the virtualization fails - you can still turn the physical box back 
on. I just need to do exactly that, but in the other direction.


Thanks
