WS2008 R2 on Citrix Hypervisor 2008R2 - only 100Mbps

[Jiri Skryja]

Hello, we got 3 WS2008 R2 on our server with Citrix Hypervisor 8.2 and when I chceck the speed of network adapter it shows only 100Mbps. I tried to install some drivers but without success. Server runs cause of it very slow. What should I do to reach 1Gbps? The server has 1Gbps ports.

Make sure your network switch is properly set either to that speed or auto-negotiate. What does "ifconfig" show as the link speed on the CH host?  For some Windows VMs, note that the actual link speed doesn't always show up correctly.

Hello, thank you for your answer, I checked the switch and it is okay I think there will be problem between citrix and the VM, I tried file transfer adn it is really really slow.   It is not even 100 Mbps, we really need 1Gbps cause there is our internal information system on this server.

Task offloading is disabled? I know this pertains to Hyper-V, but might be helpful: https://serverfault.com/questions/894135/only-getting-100-mbit-in-hyper-v-guest-from-1-gigabit-network-connection

I think my trouble are drivers. Because Citrix Hypervisor 8.2 does not support WS2008 R2. I look at windows and it installed some old drivers from year 2008. I tried to install older VM Tools but without success. Do you have any hint please?

Yea, you are still using the RealTek driver. You could very well be stuck at 100Mb/sec until you upgrade away from 2008 Server

since it is no longer supported. I don't have a system to compare with, all of my XenServers remaining are 7.x.

There is no chance to get 1Gbps? 

[Tobias Kreidl]

Worst case, you might have to install different NICs that are supported under CH 8.X and/or upgrade to a newer version of Windows Server.

If you can't get the XenServer Management Agent to install then you either need to upgrade Windows 2008 or 

you might want to try the agent for XCP-ng.

You should see better results with a supported Windows OS , preferably Server 2016 or Server 2019.

You would also need to have the latest Citrix VM tools Installed https://support.citrix.com/article/CTX225835
