XCP-NG and Mellanox 10G card

I got the card showing 10G in xcp-ng center, created a network with that NIC, and assigned that network to VM’s, but I can’t get VMS to pull 10G? anyone had this issue?

I don’t have a Mellanox card but I do have a Broadcom that has the same issue. I posted here about it.

Interesting, yeah i see the link speed in xcp-ng center says 10000. But iperf in a vm will only pull 1G. I thought maybe it was only a display issue, but nope. Have you got other 10g cards to work and pull 10G from inside a VM?

My Intel X520 cards work great at 10G
