Greetings,
I've setup an vm with openwrt in it, defined a isolated lan between the vm and the host and booted the vm up.
I see the vm is up, made sure the vnic is visible in both the host and guest and added it to the br in the guest.
I've issued an dhcpd call on the vnic (labeled vnic0) in the host and got an ip, see:
dagg@NCC-5001D ~ $ dhcpcd vnet0

the vm's xml can be found at https://pastebin.com/1gXBGcPb
virtsw0 is defined as follows:
<network connections='1'>
<name>virtsw0</name>
<uuid>c8eb15a3-cc5c-4bd6-8f3b-5790792ddccc</uuid>
<bridge name='virtsw0' stp='on' delay='0'/>
<mac address='52:54:00:3e:3f:88'/>
</network>
the os is gentoo, the versions are libvirt-6.2.0 qemu-5.0.0.
I have another server running debian 10 with the same virtsw0 definition, there the connection is working.
/var/lib/libvirt/dnsmasq/virtsw0.macs has only [] in it, can that be the issue?
Thanks,
Dagg.
