Hi all
Now I'm dong the sriov on the xen 4.1
when I try to do the following cmd:
I got some errors like below:
# xl pci-attach 7 0000:03:10.2
libxl: error: libxl_pci.c:750:libxl_device_pci_reset The kernel doesn't support reset from sysfs for PCI device 0000:03:10.2
libxl: error: libxl_device.c:470:libxl__wait_for_device_model Device Model not ready
what's wrong?
The guest os I'm using is Centos 6.3, hvm type, I have already installed the pv-drivers for it. when I execute lspci in the vm, it looks no problem.
what's wrong, please help, thanks.

xl's pci passthrough support in 4.1 is a bit flakey. I recommend you
either use xend with 4.1 or upgrade to 4.2 where xl works pretty well.
Ian.
