Hi all
I'm running several F19 hosts with multiple Gigabit NIC's
I've discovered on at least two different harware host nodes that alx
driver causes troubles in network connection
This is related to this Atheros very common onboard hardware (lspci -vv
relevant part only)

Kernel driver in use: alx
When I bond it on the ovirtmgmnt network (two gigabit bond) VMs on local
cluster run OK but they fail to mount some gluster mount points
I suppose this is related to the alx driver which seems to be not
completely working (it still misses counters)
Bringing down the relevant interface so that the bond remains with only
one NIC (ifdown p4p1) fixes the issue.
So be warned: if you have this hardware check very carefully your
network mount points inside Vms
If you have already tested this configuration and have this working
please let me know.
Best regards
Alessandro Bianchi
