And there can only be one kernel at a time. I know that with VMware there's a thing like VMware ESX server in VMware workstation (combination could be slightly different ;-)) possible. I don't know that much about the XEN internas to say if it's possible to modify XEN, so that something similar is possible. I once tried building a XEN dom0 kernel under VMware workstation 6.0 but the building process itself failed with some errors on APIC. -- Mr. Olli Am Montag, den 09.02.2009, 20:39 +0100 schrieb Julian Stecklina: > Hello, > > I am trying to build a kvm (or VirtualBox) virtual machine to painlessly > experiment with Xen on my 32-bit Linux laptop (Core Duo L2400 with > hardware virtualization foo) or my 64-bit Linux desktop box (Phenom > 8450).
