ixgbe and ixgbevf drivers are not working in virtualization environment

[Rémi Pauchet]

more informations about the SR-IOV issue.

The problem is that the link is not updated in the virtual machine (VF driver).

ie: I start the VM with my fiber unplugged, the vf link is "no carrier".
I plug the fiber, the link stays in state "no carrier".
If I reboot the vm, I get the active link. 
I reproduce the issue with esxi 5.1 and xenserver 6 


On other hand, I still haven't managed to get an active link with VMWare DirectPath.

Regards,
Rémi
