KVM networking with VM

  • I was able to install and ubuntu VM and a windows VM on the KVM plugin

    But i have networking problems


    On the OMV5, i defined a bridge with DHCP access for the ethernet card

    (This is described in the guide section under KVM)

    So my router gave the VM its ip address


    1. From the VM, i can ping the router and every machine in the rooter network

    But i can't ping OMV5. Why?


    2. Similarly i can't ping the VM from the OMV. Why?


    3. I want to be able to access any machine from any machine or any VM

    How would i do that?


    Thank you

  • Post a screen shot of the network tab and the xml network section of the VM.

  • Remove your bridge network from the Networks tab. When you use a Bridge model for the VM's network, you don't need to create a network for it.

  • I removed that bridge network in the VM, i only have isolated network

    I am able to ping VM from host (omv)

    I am able to ping VM from other machines in the network


    But none of the docker containers running on omv is able to ping the VM


    For example: i used to be able to use "docker guacamole" to remote desktop into the VM

    I guess there is no route between docker network (172,17.x.x) and this isolated bridge between the host and the guest (192.168.122.x)

    Is there away to make that work?

    I have the same setup on my system but my guacamole container is running in a VM. But I would try switching your guacamole container to macvlan networking.
