Hi list, I'm trying to run pvlinux (via pvgrub) using pci passthrough (and vga pass through), xen version is 4.2.1, dom0 & domU kernel are both 3.8.2, I checked the kernel log (DMAR) and the motherboard (H67) supports vt-d, processor is i7-2600 and it supports vt-d too. When pci passthrough is not enabled, everything is fine; but after I enabled pci pass through, domU can only see 512MB RAM (USB passed from pci-passthrough works, but video/intel didn't work, likely due to i915 load error from dmesg, everything else is also good). I googled and found a similar issue is reported at: http://lists.xen.org/archives/html/xen-users/2012-12/msg00179.html But seems there is no follow up how the problem is fixed, how can I fix the issue? Below are some links from pastebin.com: 1) native dmesg without loading xen.gz: http://pastebin.com/BTVNTi8D 2) (kernel) dmesg of dom0: http://pastebin.com/DEZ7gfmG 3) (xl) dmesg of dom0: http://pastebin.com/46bR2ngv 4) domU dmesg without pci passthrough: http://pastebin.com/DGZR4NLP 5) domU dmesg with pci passthrough: http://pastebin.com/aujxwys2 I tried xen version 4.2.0 too but still no luck. My kernel have all xen feature enabled; and I can provide more info if necessary.
