Are you saying Xen Dom0 (pv_ops) support is already in upstream ? --- On Wed, 11/11/09, Mark Johnson <[email protected]> wrote: From: Mark Johnson <[email protected]> Subject: Re: [xen-discuss] Xen a good alternative for VMware ?

The linux dom0 kernels are (or at least have been) very old since they haven't, to date, pushed dom0 support into the upstream linux kernel. VBox has *much* better desktop integration. I use it with a dual headed system where I run a VM on one screen in full screen mode and the host system on the other screen. Xen has poor framebuffer support compared to VBox and vmware. We don't even support a virtual frame buffer in solaris for Xen today (doesn't provide a lot off value to have it). Unless you doing constant local builds and are impatient, you won't notice any performance differences between VBox and Xen. And even then, you will probably me limited by your disk.
