Hi, I want to run Opensolaris as a domU on my linux box (ubuntu 9.04). Is this possible and if yes, will it offer better performance than VirtualBox and VMware. BTW, I don''t want to change distros, so it should be doable with Ubuntu. Thanks, Vikram

If this is a headless server and you want good MP performance and close to metal performance on >= 1G NICs, you should use PV guests on Xen. MRJ

However, you would have build Xen from source and build PVOPS 2.31.5 kernel from source on Ubuntu 9.04 Server, unless some packaging for 3.4.1 Hypervisor has been already done on Jaunty. Kernel to support Dom0 is still your problem. --- On Wed, 11/11/09, Mark Johnson <Mark.Johnson@Sun.COM> wrote: From: Mark Johnson <Mark.Johnson@Sun.COM> Subject: Re: [xen-discuss] Xen a good alternative for VMware ?

Hi Mark, I am trying to do this on a desktop. I was hoping that since Xen seems to be more intimately tied into the kernel it would give me better performance than VMWare and VBox which only add drivers to speed up things. Any particular reason why Xen is not recommended for desktop environments ?

http://hub.opensolaris.org/bin/view/Community+Group+xen/linux-dom0 specifically: http://blogs.sun.com/levon/entry/opensolaris_2009_06_guest_domain You have to do it the "hard" way (copy the kernel/miniroot to linux fs and boot them directly from Xen, but I think its possible in linux dom0''s without all the fancy new stuff.

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.

Sorry, bad comprehension. Thanks for feed. Kernels bellow have production quality:- 2.6.27 xenifed SLES 11 OpenSuse 11.1 2.6.29.6 xenified Next official Xen release is supposed to be out with JF''s pvops kernel (01/01/10) no matter would it merge mainline linux or no. Even in meantime 2.6.31.5 pvops is stable enough in QA environment. --- On Wed, 11/11/09, Mark Johnson <Mark.Johnson@Sun.COM> wrote: From: Mark Johnson <Mark.Johnson@Sun.COM> Subject: Re: [xen-discuss] Xen a good alternative for VMware ?
