What kind of errors do you have in mind?
The type of errors common for any SR-IOV device would be the conflict of
PCI function numbers; all function numbers that will be used by VFs
should be reserved when realizing the PF. With the SR-IOV support of
virtio-net-pci I'm adding, a user may specify invalid netdev for VFs.
