So, I fiddled with some settings in my PC's BIOS, and now I'm running a
64-bit installation of Debian inside VMware.
In spite of VMware being run under a 32-bit edition of Windows XP. :-D

Paravirtualized operating systems have to be built specifically for the
platform - I always get those mixed up; you're right, no special
hardware, special OS instead.

Yes, this is true.

I've heard of people running XEN virtual machines under VMware, but it's
not terribly stable - and completely unsupported, of course.

Like I said, turn off hardware acceleration and it seems to work just
fine. Oh, and *really* slowly... But hey, I only wanted to see what VB
looks like. ;-)

By contrast, Windows 7.
As far as I can tell, it's *exactly* like Vista. I can find only the
tiniest differences.
Interesting...

So what's the best practice with snapshots?
Whether 'tis nobler in the mind to suffer
The slings and arrows of outrageous fortune,
Or to take arms against a sea of troubles
And, by opposing, end them. To die, to sleep
Erm, wait...
If you want to test several things, is it better to take several
snapshots, or to clone the VM into several seperate VMs?
I notice that you can't run several snapshots of the same VM at once,
whereas if they were seperate VMs you could. And also you can only
reclaim freespace for a VM with no snapshots.
On the other hand, you'll never have a VM with *no* snapshots at all,
because then it would be impossible to go back in time...

I personally take snapshots as often as I commit on a version control
system.

Likewise. Only trouble is, it tends to eat disk space.
Maybe all I really need to do is go out and buy a cheap external drive...
