Do you agree with this, or is something else more likely? If the old config files are the most probably cause, how do I get the new updated ubuntu 20. Therefore, I suspect that some old config files from ubuntu 18.04 which I did not update during the upgrade are causing my problems. However it looks like you are using the virt-preview repo on f26, so now there isn't anything setting /dev/kvm permissions to 666 and groupkvm. Keeping old config files already caused me running into which I solved by manually editing the one line in the apparmor abstraction file as described in the bug fix. I remember that I kept old config files if I have manually adjusted them because I did not want to lose my custom settings/configs. However, the status in my virtual machine manager is stuck in "shutting down".ĭuring the upgrade of my host system from ubuntu 18.04 to 20.04 I was asked if I wanted to replace some config files or keep my old config files, which I have manually adjusted. Windows starts the shut down, the screen connected to the passed-through GPU goes black and I am back in my host system. Something similar happens with my Windows VM. If I try to force a shutdown using the virsh destroycommand, I get the errors error: Failed to destroy domain ubuntu18.04Įrror: Failed to terminate process 4736 with SIGTERM: permission denied Then the guest VM stays stuck like that and the status in my virtual machine manager says "Shutting Down" systemd-shutdown: Failed to wait for process: Protocol error Stopped Create Static Device Nodes in /dev. Stopped Remount Root and Kernel File Systems. The last messages I see are Stopped target Local File Systems (Pre). My ubuntu VM initiates the shutdown - I can see the normal messages during shutdown. I have two guest VMs - one "standard" guest operating ubuntu 18.04, and one guest with GPU-passthrough and an actual physical SSD (instead of a disk image file) operating Windows 10.īoth won't properly shutdown, when I try to shut them down from within the geust VM. For example in step 4 it sets the user from 'root' to 'your username' - but in Ubuntu that already would have been a special group - which is better than giving the guest permission to reach all your stuff. Previously using ubuntu 18.04, I did not experience these problems. The guide you linked does a lot of user/permission changes which would on Ubuntu be correct out of the box. As the main server (you can have multiple client connected to it)įor both methods, if you use the VPN, the host of your GNS3 server will be 172.16.253.Since my recent upgrade from ubuntu 18.04 to 20.04, my guest VMs won't properly shutdown.You have two ways to use your new server: Configure GNS3 in order to use the new server Now if you click on the tunnelblick icon in the OSX top bar. Right-click on “OpenVPN-GUI” again, and select “Connect”Īfter double clicking on the client certificate, it install the config for you.ovpn file you downloaded, and click “Import” Right-click on “OpenVPN-GUI”, and select “Import file”.Click on “Show Hidden Items” in the Taskbar.You can also find the certificate in /root/client.ovpn VPN connection on Linux ĭownload and install OpenVPN for Windows (be careful to use the version associated with your OS version) The next time you log in you will see this message:ĭownload the certificate. That's why we highly recommend to use a VPN to protect the access to the telnet console. GNS3 itself could be secured via user and password over HTTPS but because you need to be able to telnet on the routers we need to expose their console on the network. If the server is exposed on the internet, you need to setup a VPN to avoid anybody taking control of your GNS3 and the emulators. The options with-i386-repository is required only for certain providers where the ubuntu mirror doesn't include 32 bits package (example: Equinix Metal) but you can use it without problem on any host. -unstable: Use the unstable repository (for installing beta, release candidate…).Warning this will replace your source.list in order to use official ubuntu mirror vhost-net is the backend (host side) whereas virtio-net (guest side) is the frontend running in the guest kernel space. -with-i386-repository: Add i386 repositories require by IOU if they are not available on the system. Add vhostnet To improve the performance of network data transfer and reduce the load of virtio-net, we can add vhostnet kernel module in our Debian 11 Linux using the below-given command.-with-openvpn: Install Open VPN to allow access over insecure network.The details of arguments that you can pass to the script are: When the installation is done, reboot the server. This will install all the required packages and setup a VPN.
