More fun with ovftool

I tried restoring my .ova into vCenter and it failed. It said something like “Device ‘virtual disk’ uses a controller that is not supported. this is a general limitation of the virtual hardware version.” This kind of pissed me off, especially when I couldn’t really find anything in Google about what the error meant, but it turned out to be pretty easy to fix – I just clicked “upgrade virtual hardware” in VMWare Server to upgrade the hardware version from 4 to 7. I then created another .ova, uploaded it to the datacenter and successfully deployed it in vCenter in its own resource pool. Yay!

I think the real problem was that some of our VMs were created with the BusLogic driver rather than the LSI Logic driver (which is recommended for Linux guests).

Ovftool also turned out to be a pretty sweet way to backup VMs. Once in .ova format you can use ovftool to convert back to .vmx just by specifying the .ova file as the source and something .vmx as the target. Because it so nicely shrinks the .vmdk (my 20 gig VM became a 2.5 gig .ova) and is pretty quick to run (seemed like < 10 minutes per 20-gig VM) it seems like a decent choice for backing up VMs.

Exporting VMWare Server VMs to OVA/OVF with ovftool

Well, I thought this was going to be a huge pain in the ass, but it turns out not to be a really big deal. I found this post which includes instructions and a link to download VMWare’s “ovftool”. There’s a win32 version and a 32-bit and 64-bit linux version:

Windows 7 RC – day 1

So I’ve been having problems with my computer since I built it. In particular the screen will freeze up from time to time with this checkerboard of black and normal. I can’t really describe it, and since the computer’s frozen when it happens, I can’t screenshot it. Anyway, I reinstalled XP a while ago and that didn’t do anything to solve it.
