So I restarted my laptop, ran virsh net-destroy
default && virsh net-start default. Then created a new VM out of Debian 12 KDE
Live ISO (to avoid any trailing configurations).
Still the issue persists. nmcli in the guest says enp1s0: disconnected.
This looks weird. I'm not familiar with networkmanager, but I suspect
this is not telling the state of the link, is it? Because the link
should be up no matter the host side configuration.
But ps axf | grep dnsmasq gives this:
4341 pts/0 S+ 0:00 | \_ grep --color=auto dnsmasq
3995 ? S 0:00 /usr/sbin/dnsmasq
--conf-file=/var/lib/libvirt/dnsmasq/default.conf --leasefile-ro
--dhcp-script=/usr/lib/libvirt/libvirt_leaseshelper
3996 ? S 0:00 \_ /usr/sbin/dnsmasq
--conf-file=/var/lib/libvirt/dnsmasq/default.conf --leasefile-ro
--dhcp-script=/usr/lib/libvirt/libvirt_leaseshelper
What am I missing :(
One thing that comes to my mind is - ip forwarding. Libvirt sets up NAT
and should set enable ip forwarding too, but maybe that failed?
Inside the host - can you share the output of:
cat /proc/sys/net/ipv4/ip_forward
brctl show virbr0
for i in nat filter mangle; do iptables -t $i -L -v ; done
