Hello,
My new 10G NICS support now SR-IOV, and I've played with this new
feature as passthrough device, so as to reduce my host CPU consumption.
At the origin, I set up a bond on both 10G PF nics.
After many configurations, the only way I manage to use a VF into a VM,
is to get out of the bond one nic.
So does it mean that it is impossible to run a VM with VF with PF
attached to a bond?
Moreover, something strange happens : during the boot of the VM, the
passthrough device gets an dhcp IP on the native vlan of the bond, and
once finally up, the real vlan used by this device is on the different
predifined vlan. It implies to me to reconfigure the network to ping
something on the wanted vlan. Really crazy.
Other question is : In which case can it be useful to be able to bond 2
VF? UI let us to do so, but it is impossible to add any bridge on that
virtual bond.
Comparing to a large number of restrictions (migration and others), my
opinion is that this feature seems to be very difficult to use in
production...
