you can run linux guests on linux hosts and windows guest on windows hosts. 
But you cannot mix them.

It's not really virtualisation that does the magic here, it is more like a big 
chroot. You have to realize, that if you are using the linux virtuozzo 
version you are using the same kernel kernel on host and guests (not multiple 
instances, just one instance shared for all virtual servers) and you can only 
choose the distro for each guest.

Virtouzzo for windows just works on windows 2003 server, so all guests will 
also be windows 2003. There is no support for xp or anything else, and mixing 
two diffrent windows versions on one virtuozzo host would even be in therory 
impossible.

There is also an small open source version available for the linux virtuozzo 
version (not for the windows version!). it was called open virtuozzo, but if 
I rember it right they changed the name not long ago. I think the project is 
just existing, because virtuozzo on linux is using other open source 
software, so they had to release it for free. the commercial virtuozzo 
versions just brings extra goodies like remote managment via webinterface and 
so on to open virtuozzo.

But I wouldn't use virtuozzo for linux myself, because it's more or less the 
same as VServers and the open virtuozzo project has never been very popular. 
VServers should be better supported and you will find a lot more support if 
you have trouble.

Paying for the commercial version doesn't make sense if you have 
x-virtualisations techniques for linux that are for free and at least as good 
as virtuozzo (the most even better).

Virtuozzo for Windows is more interessting, because it brings a kind of 
vserver/chroot thing to the windows world. so you can run x-virtual servers 
with almost no overhead. But real (and secure) virtualisation is not 
possible, then better use vmware, xen+vt, qemu, whatever if this is a very 
important aspect for you.
