reason I ask is I want to install centos and run 2 other version (so 3 total with the host included) to study for rhce. I tried xen on (fedora 6?) and it was beyond buggy. after bouncing around internet boards I could not get the graphical manager to work.

I know I could do vmware but I'd rather use something native to linux and also I hate having to rerun vmware tools every time there is a kernel update (and sometimes having unexpected results).

so has xen improved or is it still all hype (like with a chapter dedicated to it in every new linux book) but still full of bugs or is it getting up to spec?

and if it is buggy still, can anyone suggest an alternative to vmware server that will not entail a tool like vmware tools which I hate?

oh final question. when you install the "guest" os's (for lack of the technical xen term), do you install them with xen kernels as well? in other words on the guest os do I need to select the virtualization package group when installing it?

thanks much for any insights you may have.

You might try kvm.

Native to linux? As far as I'm aware, vmware is native - you don't run it through emulation.Look into VirtualBox - simple and powerful.

As an aside, if you want things like automatic mouse integration and high resolution graphics, you'll have to install drivers compiled against the guest kernel - that means vmware tools, or in VirtualBox's case, guest additions.
