here's something of a challenge... i have a high end linux server, low load. i'm looking for ideas as to how i can get a windows 2003 machine hosted up onto it (i have a license already) on one of the machine's dedicated IPs, and set it up to host ASP based websites with MS access (have the license already too). Any tutorials or suggestions how this can be set up?
If the CPU is recent enough to have the virtualization extensions, then your best bet is probably KVM.
KVM is a kernel module and modified QEMU that work together to provide a complete virtualized environment (BIOS screens and all) running at near native speeds (comparable to and maybe even better than Xen).
Think of it as Xen without the hassle of setting up a special dom0.
When I tried KVM the module compiled and loaded first time (it is also included in the main kernel as of 2.6.20), and I had a virtual machine booting moments later. Because it is a complete system emulation it is as easy to use as a real machine.
