[Solved] Only 100 M/bit network adapter Centos vm's on hyper-v
Posted: 2017/09/12 07:03:25
Hello,
I have an odd issue with x11 forwarding. I've been googling and searching in the forum for quite a bit but could not find any solution yet.
In my home LAN I have one Mac book pro (VMWare) and one HP Proliant DL380 G8 (Hyper-V 2012 core). Both systems host Centos 7 VMs. When I forward x11 from my Mac book I get good response speeds (just like working locally) any were in the LAN. But when I forward x11 from the Proliant system the x11 windows are extremely slow. Too slow to work with. One thing is that when I connect to the Proliant based Centos systems over the hyper-v console I get fast x11, also pinging the systems give reply <1ms. So it's only when forwarding x11 over ssh that it's slow.
I'm forwarding the x11 windows on my mac using ssh -X -C using Xquarz and also to windows 8.1 using putty with x11 forwarding enabled and Xming.
Another thing is that I installed Xrdp on one of the Proliant based Centos with the same result as when trying to export x11 directly, slow connection.
I'm really unsure on how to further investigate this problem. Are there any x11 analysing programms that could check where the bottleneck is ?
One difference is that the mac book is connected to a simple Netgear switch GS108 that goes directly to the fritzbox router. The Proliant system is connected to a Cisco SG-200-26. When looking at the admin webpage of the Cisco router I see that the proliant network ports are connected with 1000 Mbit/s.
Is there any further information that I could give to clarify the issue ? Any one experianced something simmilar ?
*EDIT" changed the Title because it does not only affect x11 but shows to be a generall network device problem.
Some further information that I found : https://social.technet.microsoft.com/Fo ... rverhyperv

So basically the question boils down to: how to correctly configure a 1GBit virtual network adapter in Centos 7.3 when hosted by Hyper-V .
