Hi,
Does anyone know if pvm pci passthrough is supposed to work on xen/next
branch? I'm trying to get a device passed to the pvm, but things don't work
the same as on xen/master (where i used pciback).
Here's what i do on xen/master dom0:
echo -n "0000:05:00.0" > /sys/bus/pci/drivers/cx23885/unbind
echo -n "0000:05:00.0" > /sys/bus/pci/drivers/pciback/new_slot
echo -n "0000:05:00.0" > /sys/bus/pci/drivers/pciback/bind
Then when i boot the pvm using also xen/master kernel, it shows up on lspci,
and i can load the driver.
But when i run xen/next dom0, pciback doesn't seem to exist, so i use pci-stub
to grab the device:
lspci -n
05:00.0 0400: 14f1:8852 (rev 02)
echo -n "14f1 8852" > /sys/bus/pci/drivers/pci-stub/new_id
echo -n "0000:05:00.0" > /sys/bus/pci/drivers/cx23885/unbind
echo -n "0000:05:00.0" > /sys/bus/pci/drivers/pci-stub/bind
Now i boot the same pvm using xen/next kernel, however nothing shows up on
lspci after the pvm is up.
Is this not working yet? Or am i just doing something wrong?
My config file is the same for both, and contains the following:
bootloader = "/usr/bin/pygrub"
maxmem = 1024
memory = 1024
name = "pvm"
vif = [ 'mac=aa:20:00:00:02:17, bridge=br0' ]
disk = [
'phy:mirror/pvm_root,hda1,w',
'phy:mirror/pvm_swap,hda2,w',
]
pci = [
'0000:05:00.0'
]
vcpus=2
Regards,
Mark.
