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.
