[Xen-users] VT hardware requirements

["Geoff Gibbs" <geoff.gibbs@xxxxxxxxx>]

All,

I have been trying to get PCI pass through working for sometime and 
need to know if I have a hardware problem (does my hardware support
PCI pass through) or if I am doing something in correct.

1) My BIOS does allow me to enable VT support

2) cat /proc/cpuinfo

vendor_id    : GenuineIntel
cpu family    : 6

bogomips    : 4658.82
clflush size    : 64
cache_alignment    : 64
address sizes    : 36 bits physical, 48 bits virtual

3) dmesg | grep 0a:0e
Bootdata ok (command line is ro root=/dev/VolGroup00/LogVol00 rhgb quiet pciback.hide=(0a:0e.0)(07:00.0) pciback.verbose_request=1 apic=debug pci=routeirq)
Kernel command line: ro root=/dev/VolGroup00/LogVol00 rhgb quiet pciback.hide=(0a:0e.0)(07:00.0) pciback.verbose_request=1 apic=debug pci=routeirq

ACPI: PCI Interrupt 0000:0a:0e.0[A] -> GSI 18 (level, low) -> IRQ 20
ACPI: PCI interrupt for device 0000:0a:0e.0 disabled

4) cat xen_foo.cfg
name = "xen_foo"
uuid = "cab66c9faa4b7049d5d10293f13bfc7f"
maxmem = 500
memory = 500
vcpus = 1
builder = "hvm"
kernel = "/usr/lib64/xen/boot/hvmloader"
boot = "c"
pae = 1
acpi = 1
apic = 1
>>>device_model = "/usr/lib64/xen/bin/qemu-dm"
sdl = 1
vnc = 0
vncunused = 0
keymap = "en-us"
disk = [ "file:/var/lib/xen/images/xen_reo.img,hda,w" ]
vif = [ "mac=00:16:3e:72:06:c0,bridge=xenbr1,type=ioemu", "mac=00:16:3e:28:51:79,bridge=xenbr1,type=ioemu" ]
serial = "pty"
pci = ['0a:0e.0']


When I create "foo", the system boots, but does not load the kernel module aacraid which is device 0a:0e.0. reports
the following:

Adaptec aacraid driver (1.1-5[2430]custom)
ACPI: PCI Interrupt 0000:00:03.0[A] GSI 28 (level,loq) IRQ 17
aacraid: aac_fib_send: first asynchronous command timed out.
Usually a result of a PCI interrupt routing problem;
Update mother board BIOS or consider utilizing one of the 
SAFE model kernel options (acpi, apic etc)
ACPI: PCI interrupt for device 0000:00:03.0 disabled
aacraid: probe of 0000:00:03.0 failed with error -110


I really need some help with this.

Thanks,

Geoff
