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*

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)

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
on_poweroff = "destroy"
on_reboot = "restart"
on_crash = "restart"
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
