Following the guide:
( the main KVM guide on this domain, newbie, can’t yet post links )
all appears to have gone well, up to:
( that same main KVM guide on this domain )
#Importing_Whonix_.E2.84.A2_VM_Templates
More precisely, the first lines went fine:
virsh -c qemu:///system net-define Whonix_external_network-15.0.0.8.7.xml
virsh -c qemu:///system net-define Whonix_internal_network-15.0.0.8.7.xml
virsh -c qemu:///system net-autostart Whonix-External
But I get the following error at:
virsh -c qemu:///system net-start Whonix-External
error: Failed to start network Whonix-External
error: internal error: Failed to apply firewall rules /usr/sbin/iptables -w --table filter --insert LIBVIRT_INP --in-interface virbr1 --protocol tcp --destination-port 67 --jump ACCEPT: iptables: No chain/target/match by that name.
In the /var/log/syslog, at the time that failing command is issued, I find:
2020-05-28T19:07:00.892332+00:00 thehost kernel: [11657.591323] virbr1: port 1(virbr1-nic) entered blocking state

Of course, no virbr1 to be found:
# brctl show
bridge name bridge id STP enabled interfaces
virbr0 8000.525400b0af6a yes virbr0-nic
That’s just the default libvirt’s virbr0.
Similarly, I couldn’t start:
virsh -c qemu:///system net-start Whonix-Internal
Same error, just 's/virbr1/virbr2'
. Also for the logs, which are same, except for 's/virbr1/virbr2'
and time is some 10 minutes later.
There are even scary suggestions what that might be:
(lnewbie, can’t yet post links, but it’s on experts-exchange commercial domain )
I sometimes do tcpdump’ing, however, at the exact time of the failing command above, I wasn’t capturing traffic. So…
What could this be? How should I proceed here towards a solution?
