VM restart - no access anymore (network)

Fri, 04 Aug 2023 13:15:37 GMT

Hello

I created the virtual machine and started it (br21)--> Works.

The virtual machine restarted (br21), no longer works.

Added or changed a new IP address to the virtual machine does not work either.

Its maybe for your server network interface changed. You can create Network Bridge to avoid network problems.

Good day

When I create a new VM, everything works (network, access to the VM etc.)

But when I restart the existing VM, I no longer have access (no access to the VM - via network).

Does anyone know this problem - possibly bug?

Thanks

Greetings Dave
