Re: [Xen-devel] pci hotplug in xcp

Thanks Stefano.

I am having problems binding device to pciback(this is from day1). Driver for this device is not loaded in dom0 so this device is not bound to any driver. 

#echo $pcidev
0000:08:01.0

# echo -n $pcidev > /sys/bus/pci/drivers/pciback/bind
-bash: echo: write error: No such device

ls -l /sys/bus/pci/drivers/pciback/bind
--w------- 1 root root 4096 Apr  8 07:40 /sys/bus/pci/drivers/pciback/bind

Any inputs?

Thanks

did you bind the device to pciback before executing "xl pci-attach"?
xl doesn't do it for you.
Beside you need to add -priv to the qemu command line options and to do
that you need to edit /opt/xensource/libexec/qemu-dm-wrapper for example
adding

qemu_args.append("-priv")

right after

qemu_args.append("pty")

sorry for not mentioning this before :)
