Not yet... I'm planning to do so ASAP. I've been trying and trying to get xen going on my new sandy-e system and have gotten the hypervisor to load but the dom0 kernel panics during boot. I dug up an old copy of FC 15, will try my luck there next. Never tried FC15 either, but just installing the xen packages in FC16 brought up a working virtualization environment every time I tried. I'll give it a go again (no, I don't have them installed right now) and let you know if that still works for me. Regards, Dario Dario, Yes, 16 is what I meant to type (oops). I did a minimal install, and without updating, did a yum install xen, tweaked around with grub.cfg and the network-scripts a little and boom hypervisor and dom0 up and running, with VT-d support. Tried the same thing with 17 again and could not get the dom0 kernel to boot successfully. I'm going to buy a serial card for this machine so I can do the serial console on Xen and get more information. But so far, so good!

You can try to do (on Xen) 'console=vga vga=text-80x50 guest_loglvl=all loglvl=all noreboot and on the Linux command line: console=hvc0 earlyprintk=xen loglevel=8 debug radeon.modeset=0 radeon.modeset=0 That should give you some idea where it is crashing and take a photo. If you are capturing logging with a photo, it can be helpful to add a boot_delay parameter eg. boot_delay=100 to the kernel line, particularly if the interesting lines scroll off the top of the screen before you can capture them. It does slow the boot down considerably though so you may need to adjust the parameter to get the balance right between it being slow enough to capture without taking ages to get to the crash.

Michael Young Thank you for the tips everyone! I will retest the FC17 beta as soon as find another hard drive... having some fun with VT-d right now. I've been trying vt-d on every new machine I've built or come across at work, and finally arrived on a home machine that does it, without having to run a server grade mobo and cpu (pretty close though). Specs: Core i7-3820 Sandy Bridge-E cpu 4 core, 8 thread Asus Sabertooth x79 main board 32gb ddr3-1600 ram Radeon HD7970 graphics adapter I'll post up my vt-d success story in a separate thread, but I was grinning ear to ear when it first started working.

That is very cool! If you want to put it on the Xen wiki as well (http://wiki.xen.org/wiki/Main_Page), please feel free to go there and post an article. Maybe here http://wiki.xen.org/wiki/Category:Tutorial, or here http://wiki.xen.org/wiki/Category:HowTo, or as a followup of this http://wiki.xen.org/wiki/Fedora_16_Dom0 ...or wherever you think it fits. We're really striving for that kind of contribution! :-) Regards, Dario -- This happens because I choose it to happen!
