I posted over the weekend about my problem accessing Cockpit, which I found the solution to shortly after posting. However, I have run into a separate issue in Cockpit related to the Virtual Machines tab. I tried to create a new virtual machine (a basic Ubuntu machine) and received an error:
ERROR Requested operation is not valid: network 'default' is not active Domain installation does not appear to have been successful. If it was, you can restart your domain by running: virsh --connect qemu:///system start Ubuntu otherwise, please restart your installation.
This led me to this guide, which seemed promising. But when I got to entering the virsh net-start default command, it threw this error:
error: Failed to start network defaulterror: internal error: Failed to initialize a valid firewall backend
When I run virsh net-list --all, I get this:
Name State Autostart Persistent
----------------------------------------------------------
default inactive no yes
Some of the "solutions" I found suggest installing firewalld and a handful of other packages, but once I installed firewalld I immediately lost access to the OMV web GUI and shellinabox. I have since uninstalled firewalld. Do I need to install and configure firewalld somehow in order to get Cockpit to allow me to install virtual machines? I have been searching for hours and have yet to find anything helpful except a post from December that doesn't really have a solution that I can understand. I tried the virsh # net-define /root/default.xml command but that just got me into the virsh terminal, which I have no idea how to use.
Anybody have any suggestions?
Thanks in advance!
