comment 2012R2 Hyper-v host CentOS7 guest slow network speed over external network
Well, I finally got the new switch, but that is not what solved the problem. I've found out, that I've given static IP for the CentOS guest, as usual, but when i've tried a same instance of this guest with DHCP networking, and ran dd, it was be able to use the gigabit network (113MB/s). When I switched to static ip, I got 100Mbits again. It's really strange, but it is working now properly.

I'll give a try to the another NIC in SR-IOV mode without host sharing, gaved only to the CentOs guest as soon as i'm phisically near to the server and when I got the new switch. Or maybe I'll setup NIC teaming between the to apadters.

Yeah that can be a problem, but VMQ is unneccesary for this host, because only this CentOS guest needs much traffic. The couple other guest are used for monitoring via snmp.
