I'm setting up a new machine running trixie to run virtual machines,

virtual machines.
Is it possible to set things up so that the virtual machines are on the
same network as the host machine? The host is on 192.168.100.0/24. Can
I have the virtual machines also on 192.168.100.0?
Yes see below! ;^)
This is what I use in "/etc/systemd/network":
==> br0.netdev <==
[NetDev]
Name=br0
Kind=bridge
MACAddress=<MAC-ADDR-OF-INTERFACE-TO-BE-BRIDGED>
==> br0.network <==
[Match]
Name=br0
[Network]
DHCP=ipv4
Note that this is an HYP the DHCP leases are coming from upstream for
the host and the VMs.
I use "--network bridge=br0,mac=<VM-MAC>" as part of the virt-install CMD.
HTH.
P.S.
You need phisical access to the host if something goes sideways when
setting up the bridge!
