Re: [Xen-users] how to install Windows without hardware support

["Nick Couchman" <Nick.Couchman@xxxxxxxxx>]

As stated before, the answer is no, you cannot run Windows on Xen without VT hardware.  It isn't just Windows, either - you cannot do "Full Virtualization" on Xen for any operating system without VT hardware.  If you don't have VT hardware, you must use paravirtualized mode, which limits your O/S choices to Linux, OpenSolaris, and a few BSD flavors.

Yes.i agree paravirtualization is better.But i was wondering if we have no VT hardware and still want to put windows on Xen. Can Qemu VMs be managed through the xen interface.

No... You cannot install windows in a non-VT hardware using Xen as your VMM.

With QEMU is possible, but u gonna have a lot of performance problem... =/

If you wanna virtualize your data center and dont have the VT tech,
you should use paravirtualization... remember that paravirtualization
has some advantages, like better IO.
