I’ve read through these, however I’m on xenserver 6.2 and would rather not hack the ramdisk because any future update would obliterate that (most likely).
Per gordon’s request, I’ve reset my system back to factory and here are the lspci/dmesg/xl dmesg.
I can confirm that I do not load any radeon or radeon related drivers in dom0, however I cannot seem to hide the pci bus for it. Are the modules missing for
XenServer 6.2 (xen 4.1.5) ?
Not sure if attachments are acceptable, so I’m going to put links to pastebin.
xl dmesg:

lspci –vvv
http://pastebin.com/t7paAyBa
lsmod
http://pastebin.com/tZTA5T4K
dmesg
http://pastebin.com/hiGcq9GS
The citrix support guide says nothing about hiding the device at all (which I tried the extboot.conf stuff to hide the pci devices to no avail).
If there’s a way to confirm xen-pcihide or whichever it is (many articles .. two names, not sure which is right) as loaded on xenserver 6.2 that’d be appreciated.
I have in blacklist.conf:
blacklist radeon
blacklist fglrx
We shouldn’t ever touch those two modules… so I should be good for passthrough right?
I’m basically starting from ground zero at this time. Thanks for the help.

Subject: Re: [Xen-users] Help with VGA passthrough
In addition to the suggestions given before, here some information sources:
I'm trying to get vga passthrough to operate normally and have been rather unsuccessful despite attempting to replicate hardware stated to work much reading about the mail list and wiki.
Setup:
Xenserver 6.2 SP1 (all patches)
ATI Radeon HD 6450
ThinkCentre M series with Core i5
I've read:
http://support.citrix.com/article/CTX135811http://support.citrix.com/article/CTX135811
http://wiki.xen.org/wiki/Xen_VGA_Passthrough
The GPU assignment to the HVM works fine through both api and gui (xencenter), however the domU can't initialize it. I've tried pciback.hide and xen-pciback.hide for the pci buses the ati card shows up as, however to no avail and results in it unable to use
the gpu.
Dmesg about the pci bus (01:00.0 and 01:00.1):

Here's dom0's extboot.conf for xe's boot:
label xe

append /boot/xen.gz mem=1024G dom0_max_vcpus=4 dom0_mem=2048M,max:2048M watchdog_timeout=300 lowmem_emergency_pool=1M crashkernel=64M@32M cpuid_mask_xsave_eax=0 console=vga vga=mode-0x0311 --- /boot/vmlinuz-2.6-xen root=LABEL=root-lsodryqz

So I've hidden them, however they're still showing up on dom0 and failing init on domU.
Can anyone provide some help?
