    • Cockpit - Qemu and VirtMachine

      Good evening

      I followed TechnoDadLife's tutorial for docker cockpit (Thanks a lot :))

      I'm just having a problem because I wanted to make a VM but when I launch the virtual machine I get the following error message:

      Source Code

      1. INSTALL VM action failedshow less
      2. Networking does not appear to be successful. If it was, you can restart your domain by running: virsh --connect qemu: /// start system Mint19 otherwise, please restart your installation.

      I looked on the internet for this error message but unfortunately it does not seem to correct my network level error.…th-matching-name-default/

      Now I end up with no default network for qemu because I placed the order

      Source Code

      1. virsh net-destroy default

      Brainfuck Source Code

      1. root@openmediavault:~# virsh net-list --all
      2. Name State Autostart Persistent
      3. ----------------------------------------------------------
      but I can not put a hand back a card by default

      Could you help me to put a default route back and if possible allow me to run the vm ?
    • I logically found I have to do one:

      Source Code

      1. root @ openmediavault: ~ # virsh net-create default.xml
      2. error: Failed to create network from default.xml
      3. error: internal error: Failed to initialize a valid firewall backend

      but I have an error message regarding the Backend Firewall

      on the internet it indicates to fix this problem that it is necessary to install dnsmasq and firewalld ebtables

      Source Code

      1. apt-get install ebtables dnsmasq firewalld

      but if I do this after a reboot I no longer have access on the services on OMV, the rules of the firewall must block the access.

      I try the command :

      Source Code

      1. virsh # net-define /root/default.xml
      and the network card was created but I still end up with the same firewall backend problem.

      EDIT :

      I think I found, there would be a bug in ebtables:
