Error with Synthetic Ethernet Port
Hello,
I'm trying to create a new VM associated to an external network adapter on Hyper-V RC0. At the end of creation, the VM tries to start but two messages appear on the host machine and the VM disappears (sorry, I use the french version of Windows Server 2008 RTM) :
Virtual Machine Connection[Main Instruction]

If you change the virtual machine's network adapter to be 'not connected' does it start up correctly?

- Yes, I tested with "not connected". After, I added the network adapter and the VM starts without problem.
It's curious because I created some VM before and I hadn't any bug.
Krys - Any fix on this??? I have a fresh system, just installed. Added the RC0 of hyper-v and I am receiving the same issue mentioned above when trying to create and boot a new VM.Derek
I've updated Hyper-V to RC1 version. The creation of a new VM (with virtual network adapter) doesn't reach. The "Synthetic Ethernet Port" error appears again.

- Try to uninstall/disable AV software.
- I have find the same problem with hyperv rc1 and a linux guest vm with ic component installed but my linux vm does not start with or without lan connection ( virtual external lan or not connected in setting vm).
When i try to start the vm i receive the error with the synthetic ethernet port and if i close the hyperv manager and reload new one the vm does not appear. - mityak said:

Yessss!! That is the solution for me. I had Windows 2008 Standar 64 Bits Hyper-V but I install Forefront Client Security and New Virtual Machine Wizar failed with this error.
I stopped the services "Microsoft Forefront Client Security Antimalware Service" and "Microsoft Forefront Client Security State Assessment Service". I run the New Virtual Machine Wizard again ... and this run without problems.
Thanks for your help.
Fennix Try to uninstall/disable AV software.
Yes! Antivirus software "TrendMicro OfficeScan Client 10" blocked my etherner card.
Thank you.- Proposed As Answer byMark J Casey Monday, November 16, 2009 12:47 PM
