The single biggest weakness that I've seen for VirtualBox is its
inability to resize disk images after creation. This leads to creating
additional virtual disks to present to the guest.
If you're hoping to resize the Windows filesystem to utilize this
space, make sure to use "dynamic disks":

If you haven't already, give the GPLPV ("ParaVirt") drivers for XP a quick try.
They're supposed to help network and disk performance significantly:

This is actually the likely route for me. I was just hoping to stick
with our existing Xen infrastructure.

Why not use VMware ESXi? It works great with Windows or Linux VMs.

If your hardware doesn't support ESXi, I suggest trying "VMware Server",
also free. It doesn't run on the "bare metal", but it does run very well and
works with almost any Linux distribution:
http://www.vmware.com/products/server/
I've successfully used it to virtualize WinXP systems in the past,
Assuming you have recent and non-homebrew Intel hardware, you can
probably run ESXi, although VMware Server will work. (Although I heavily
suggest using ESXi over VMware Server where possible.)
ESXi is a snap, quite fast, and I've never had an issue running XP or
any Windows boxen under it.
Yeah, I think my plan will be to throw ESXi on a nice shiny new
PowerEdge R710 :)

VMWare Server is a terrible product. I wouldn't recommend it for any
purpose.
Perhaps you should look at ESXi? Does the host need to be Linux, or perhaps
bare metal w
There is just one problem with ESXi. How do you make your disks redundant?
If you have something like a RAID controller card, you can configure the
disk redundancy in BIOS. But then if a disk goes bad and you need to
reassign the global hotspare ... there is no built-in or 3rd party utility

Completely agree, with the addition that we found NFS to perform
better than iSCSI (YMMV). In fact if you have SAN/NAS and
VirtualCenter, you don't even need local disks in the ESXi servers,
you can PXEboot or use a USB key!

I'd probably go USB boot in that case. PXE is just another subsystem
to break and fail other things.
Incidentally, if you've got a Dell system, you can install the
OpenManage VIB in ESXi to gain access to the underlying RAID system -

Yeah, I have been leaning toward ESXi. No problem with that since I can
