    Windows 10 Hyper-V network connectivity lost after a while


    I'm using the latest Windows 10 Pro build, installed Hyper-V, created a VM (windows 10 as well), with the default switch. Once up and running, the VM got Windows updates, and eventually lost network connectivity with the host. I re-created the VM 3 times now and same thing, after a while the connectivity is lost. Inside the VM there are no network connections. I tried un-installing Hyper-V and re-installing it, on the host, and nothing.


    Any ideas?


    Thanks

    :)

  2. Hyper-V networking

    Windows 10 Pro, Build 10586.71. Hyper-V installed. All was working well, and then I got a chipset update from Dell. Installed the update and rebooted computer. After that networking was not working correctly, windows showed limited connectivity. I looked
    a little to roll back the driver update, but Windows did not show a new Nic card driver and the chipsets I looked at also did not show a current date. The Dell Command update program does not provide a way to uninstall updates.

    I tried to access hyper-v switch manager but it returns an error that "an error occurred while trying to retrieve a list of virtual switches". Also tried using the powershell cmdlet but got a general error.

    I accessed the networking center and deleted the Hyper V adapter, then edited my LAN card's config disabling the two Hyper V protocols and enabling the rest. This let me get back on-line with my computer. I have tried uninstalling the Hyper V feature,
    reboot, reinstall - but I am still unable to access the switch manager. I then removed the feature again, re-named the C:\ProgramData\Microsoft\Windows\Hyper-V directory, rebooted, added the feature again. This time (obviously) none of my VM's show up but
    I'm still unable to access the switch manager.

    There is no critical data in my Hyper V, I use it for testing, re-creating issues, learning, etc. Is there a way for Windows 10 (or something designed for server 2012 that will apply) that I can use to fully reset the Hyper v networking, or fully rest all
    of hyper v so I can get it working again? I do use the workstation heavily, it's my work computer so it would be very difficult to impossible to reinstall the OS.

    Thoughts and suggestions appreciated.

    Hyper-V Connection Lost


    I am having trouble establishing a stable connection to a Windows 10 VM and the issue appears when I activate enhanced mode. The error message that I'm getting quite often is the following: "The connection was lost because another user connected to the virtual machine." There is no one else connected to it. After doing some research online, I discovered that others are also experiencing this issue. For what it's worth, Windows 8 is the host OS and one of the suggestions was to install the optional Windows update KB3071740, however that did not solve it. Has anyone found a workaround? It is frustrating not having the ability to run Windows 10 in enhanced mode in Hyper-V.

    Windows 10 Hyper-V network connectivity lost after a while

    Cannot connect to network in Hyper-V when using default network


    Instead of using RDP to connect to virtual machines which are using Default switch on remote host, I just add that host to my Hyper-V Manager on primary host.

    Click Hyper-V Manager on left pane:

    On Actions pane, select Connect to Server:

    Enter remote Hyper-V host name:

    If that remote host does not have exactly the same admin user credentials than your primary host, select Connect as another user entering the credentials to remote host:

    That's it.

    Note To connect to remote Hyper-V host, both your primary host and remote host must have WinRM service running and Trusted Hosts list on both hosts must contain both computers.

    Prerequisites are exactly the same than in using Windows Admin Center to connect to remote computers. See Part One in this tutorial to set both computers up correctly: Windows Admin Center - Centrally manage all your Windows 10 PCs | Windows 10 Tutorials

    Step 3.9 in above mentioned tutorial will show some troubleshooting tips if you cannot add remote hosts in Hyper-V Manager.
    This way, you can connect to any VM on remote host, with normal or enhanced mode. This basically makes RDP unnecessary.
