Quite old topic, but I have been struggling for MONTHS (literally) now and I'm getting stressed in daily life.
I have everything working so far to the point where it is showing in xencenter as a valid nic with 2500mbit full duplex specifications.
using this usb nic: https://www.club-3d.com/en/detail/2467/usb_3.1_gen1_type_a_to_rj45_2.5gbps/
I can ping with it, connect to it with SSH and give the NIC to my windows server VM. The only problem that is holding me back from using this USB nic is that all my windows VM's are getting SSL errors on any internet browser i'm on. Internet just doesn't work.
Besides that I can't even copy files from any VM to my normal PC anymore since it's getting stuck on 0KB/s and eventually crashes my explorer.exe.
Something is really wrong here and man... I must have had every single guide possible in front of me I'm sorry for reviving this thread but i'm getting desperate.
I hope there is someone who can help me maybe through email or this forum. I'm willing to share everything I did to get this working.
