My task is to enable a (remote) server to run VMs via qemu/KVM.
The server is configured to set up its eth0 via openrc but this isn't
enough to run the VMs network.
I tried macvtap but something didn't work, either libvirt (yes, with
USE-flag "macvtap") or something else (the kernel supports mavtap).
So bridging.
I'd like to keep the risk of losing connectivity as low as possible ...
I can visit the place in a few weeks to iron out things but I would like
to set up a bridge now without failure, just to get that VM running asap.
Could anyone advise me in doing this?
I have only ssh-access now ... its openrc-driven, and I might use a
second IPv4-IP if that helps ...
anyone?
(editing the conf.d-files to remove eth0 and setup br0 is too scary
right now. One mistake and the box is offline)
