-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, I''ve been working on a project recently which we want to virtualize. It runs on Windows Server 2003, so my first attempt was to put it in a HVM domU. Sadly, this application requires network performance higher than HVM is seemingly capable of. In the absence of PV drivers for Windows, I tried running it on VMWare instead, and I got the extra network performance I was looking for. However, rather than having to have VMware hosts alongside Xen hosts, I''d much rather run VMware on the same physical box as Xen. Obviously I can''t run it in dom0 or in a PV domU (according to what I''ve seen on the net, the kernel modules VMware uses attempt to force it into ring 0, which causes a General Protection Fault), so I''ve tried running it in a HVM domU (CentOS 5, with PV drivers to improve the network performance). I''ve seen several posts on several lists via Google suggesting that HVM domU''s have a virtual ring 0, which should suffice. While I''m no longer getting a GPF, the Windows VM still refuses to start, most of the time giving me no error message but sometimes it pops up a box telling me about an unrecoverable error, unexpected signal 11. I can''t determine anything useful from the log file either. So, the question is, has anyone tried (or had any success with) getting VMware and Xen to co-exist on the same box? If you have, how did you do it? If not, I''d appreciate any ideas as to how to achieve this, or (perhaps preferably) any hints to improve network performance under HVM. Or if anyone''s got any alternative ideas I''d be happy to hear them. Of course, the best solution would be to have open source PV drivers for Windows, but I don''t think that''s even on the horizon. Thanks in advance for any input.

Never used HVM so I can''t say whether this suggestion applies.

Oddball suggestion: Download the Linux version of VMWare Server, run it on the Dom0. Do both at the same time.

I''m not sure it would work since Dom0 is not running a Linux kernel with "everything on it". I think VMWare expects access to hardware or portions of the kernel that are likely to be missing in a Xen Linux kernel. Supposedly you''re not supposed to be able to run QEMU within Xen either for similar reasons (especially when you''re paravirtualised). Anyone have any more info? Gary W.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Cheers for the suggestions, however I already tried these and they didn''t work (running VMware in dom0: got a General Protection Fault, probably as dom0 is still a VM and cannot run in ring 0, assigning NIC to domU: I''m pretty sure the problem is to do with the device emulation, not the network bandwidth) Thanks anyway, Martin Gary W.
