Re: [vfio-users] Arch, Virt-manager and Network Manager [help needed]

[Jonathan Scruggs]

Network Manager has some serious bugs. The best way to create a bridge is
to delete all the networks from Network Manger. Then configure
systemd-networkd scripts. It's not hard. In fact, stupidly easy. Enable
systemd-networkd. Then add the bridge in Virt-Manager.

The Network Manager creation of a bridge is very unstable, which is the
opposite you want for a VM. Also, you have the added bonus of starting the
bridge earlier. I would share my scripts, but I'm in Spain away from my
desktop at the moment. I still use Network Manager to use OpenVPN easily.
The new versions of NW have a fix so they don't display networks they
didn't create, so you have no worry about messing up the networkd scripts.

That depends on where you want to define your network connection. Both is
possible.

that was network definition, not virtual machine. I do not know why this 
is needed, I do not use those at all.

Here is xml of my VM, using "br0" bridge I defined with netctl:


  
  
  
  
  function='0x0'/>




I expect it does not matter how a bridge is defined, as long as it 
works. In /etc/libvirt/qemu.conf I have the below line:

bridge_helper = "/usr/lib/qemu/qemu-bridge-helper"

I've done the same. Bridge created with NM and used by the VM. You should
be able to just select the bridge device. That's the resulting XML for me:


  default
