VM ~ 2.8GB 7z 9.3GB full

I did figure out at least 3 ways to mount a vm disk outside running it
to do the zero fill.

vmware-mount (Catch 22, it works on Ubuntu 8.04 but 8.04 can't mount
ext4 so it fails. Vmware is nearly impossible to getting running on
later Ubuntus - so dead end unless I want to custom patch my kernel for

qemu-nbd On a machine running kvm virtualization. Works great but kvm
requires vt instruction set (older server doesn't have that) and can
conflict with vmware kernel modules

vdfuse Requires virtualbox-ose-fuse, I might be able to get this to work
on my kvm box but also mutually exclusive with vmware kernel modules.

So in the end it took a little longer this time but I know the methods
work (I did qemu-nbd but I'm confident vdfuse will also work).

Down the road I have some new servers ordered and once they come in I'll
be getting rid of vmware asap and moving to kvm/virtualbox. I'll keep
vmware around just long enough to finish version 5 just in case it's needed.

This also means I'll be switching compression methods and probably
moving to virtualbox's vdi format as the finished product (since Vbox
shrink tool only works on vdi).

Any objections to switching to vdi instead of vmdk? I can always convert
between using qemu but virtualbox seems the most likely desktop solution
people will use.


PS: Apologies for the brain dump, let me know if I need to explain
anything in more detail.
