I run xen-4.14.3-pre from debian
I created 6 vfs for my igb card
06:00.0 Ethernet controller: Intel Corporation I350 Gigabit Network
Connection (rev 01)
I got these

However the guest is not able to see the link up.

I see this error on the guest

interface up?

a read-only configuration space field at offset 0x1d6, size 2. This may be
harmless, but if you have problems with your device:
[ 395.849996] 1) see permissive attribute in sysfs
[ 395.849996] 2) report problems to the xen-devel mailing list along with
details of your device obtained from lspci.
[ 396.103595] pciback 0000:07:10.1: enabling device (0000 -> 0002)
However if I pass through 07:10.4 it works fine. The host still reports
this above error but all works well in the guest.
Please could someone help ? I have been using KVM these years and just
moved to xen and hence new to xen.
