Re: no-carrier on qlogic 8242 10gig with linux 3.x running xen

This is ip a showing no-carrier, even if the NIC is upped with ip link set

This is before any network configuration is run.
/etc/network/interfaces is disabled - I run openvswitch and do all network
configuration in some custom scripts. 

Without xen it works - the irq's exist.
