[QUOTE="fujistick, post: 599406, member: 65261"] OK new plan, I’m not going to give up just yet. :) I’ve been reading a bit more about Xen, and it appears as though it may be possible to passthrough the primary VGA card to a VM. i.e. it’s used during initial boot up of the base hypervisor, then when the relevant VM is started, the VGA card is reset and control passed through to the VM with the underlying hypervisor (i.e. Xen) still accessible via the network. To me, this sounds very interesting and warrants further investigation. Basically I would be able to set up a TV server VM with the 2 tuner cards passed through to it, as well as a MP client front end VM with the graphics card and sound card passed through to it, all on the same hardware, completely independent of each other. Jackpot! There are still issues with this plan though. The RAID card is not working so I would have to leave that out. Linux has software RAID so I’ve still got that functionality. I have 6 x SATA hard drives + 1 SATA BluRay drive, but only 6 internal SATA ports on the motherboard. There are 2 eSATA which I’m not sure if I can use. That also gives me no room to expand. The RAID card had spare ports for me to expand into as required. But I’ll cross those bridges when I get to them. To start with, I need to confirm if this is even possible by testing whether VGA and PCI passthrough will actually work. The latest stable build on Xen is 3.4.2, but there is a new version 4.0.0 which is on the verge of being released. I think it’s up to RC8 right now, but [url=http://blog.xen.org/index.php/2010/03/26/xen-org-weekly-newsletter-vol-10-no-12/]Xen.org Weekly Newsletter Vol 10 No 12 – blog.xen.org[/url] suggests that it’s going to be released in the next few days. I believe this version fixes a lot of bugs and hacks and workarounds regarding VGA passthrough. I’ll keep you all posted. [/QUOTE]
