https://community.hpe.com/t5/operating-system-microsoft/proliant-dl380g6-hyper-v-instance-network-anomaly/m-p/4554777#M11987 Hi, I solved the problem by using Action -&gt; "Insert Integration Services Setup Diskâ to install the Hyper-V integration services and it will make the HP host network adaptor appear in the guest OS.<BR /><BR /> Sat, 02 Jan 2010 18:50:12 GMT Y M Tan 2010-01-02T18:50:12Z https://community.hpe.com/t5/operating-system-microsoft/proliant-dl380g6-hyper-v-instance-network-anomaly/m-p/4554774#M11984 Hi,<BR />We installed Windows Server 2008 x64 Std Edition with 12GB RAM, Single Quad-Core Processor, 3x146GB SAS HDD and created a Windows Server 2003R2 Std Edition instance.<BR /><BR />We followed the advice of HP Hyper-V support manual to install latest PSP and update the driver. <BR /><BR />In the Hyper-V Manager, we cannot see the HP Network Adpator Driver but a Microsoft virtual network adaptor. We did try to install network adaptor driver comes with HP server but failed.<BR /><BR />We found that the speed of the new network adaptor runs very fast. However, whenever we transfer big files (&gt;2GB), the behavior of the Hyper-V instance became weird -- it suddenly slows down for a while, and then resumes the speed again.<BR /><BR />During this slow period, the host CPU utilization is low and nothing special found in the event log as well.<BR /><BR />Can anyone enlighten us with possible solution?<BR /><BR />Thank you.<BR /><BR /><BR /> Wed, 23 Dec 2009 15:01:44 GMT https://community.hpe.com/t5/operating-system-microsoft/proliant-dl380g6-hyper-v-instance-network-anomaly/m-p/4554774#M11984 Y M Tan 2009-12-23T15:01:44Z https://community.hpe.com/t5/operating-system-microsoft/proliant-dl380g6-hyper-v-instance-network-anomaly/m-p/4554775#M11985 Not much help but I remember having the same problem. I did get it working but it was months ago and I'm not sure what I did to resolve it. I seem to recall that I had to add the networking manually. There may have been something in Technet about it.<BR /><BR /><A href="http://technet.microsoft.com" target="_blank">http://technet.microsoft.com</A><BR /><BR />Make a great 2010<BR /><BR />Roger Fri, 01 Jan 2010 07:08:09 GMT https://community.hpe.com/t5/operating-system-microsoft/proliant-dl380g6-hyper-v-instance-network-anomaly/m-p/4554775#M11985 Roger Faucher 2010-01-01T07:08:09Z https://community.hpe.com/t5/operating-system-microsoft/proliant-dl380g6-hyper-v-instance-network-anomaly/m-p/4554776#M11986 Not much help but I remember having the same problem (adapter not showing in Hyper-V Manager).
