[Xen-devel] PCI Passthrough question (xm->xl migration in Xen 4.2.2)

[Saurabh Mishra <saurabh.globe@xxxxxxxxx>]

In XM toolchain, we use to put pci = [ '0000:07:11.6=0@1a' ] but looks like in XL toolchain there is no way to specify function in the guest.

Kindly let me know.

XM  - pci = [ '0000:07:11.6=0@1a' ]

XL   - pci = [ '0000:07:11.6@1a' ]

In the guest VM we see that PCI device is getting 0 function in both the cases however, it may not work the same way in the future.
