libvirt.libvirtError: internal error: Failed to initialize a valid firewall backend... Moreover, there's another thing I don't understand: after installing iptables, I noticed it hasn't anything to "run" the firewall: no servers (it doesn't exist, e.g., an "iptablesd"), no command line flags ("iptables -d" or such), no kernel modules (I didn't find any "iptables.ko" or similar). So my question is: how can it work if there isn't an "active" component?
Comments: Iptables is the userspace tool to control
the linux kernel firewall. A simple script
included, suitable for home users.

/usr/local/sbin/basic-firewall nopromptNo, in fact I tried installing iptables, but nothing changes:In TCL, kernel functionality required for firewall is in the ipv6-netfilter-KERNEL.tcz extension (which is a dependency of iptables.tcz). It should have been automatically installed when you installed iptables.tcz, but please check to make sure. When you run this command, does it say the extension is already installed?Code: [Select]Error starting network 'default': internal error: Failed to initialize a valid firewall backend

Moreover, there's another thing I don't understand: after installing iptables, I noticed it hasn't anything to "run" the firewall: no servers (it doesn't exist, e.g., an "iptablesd"), no command line flags ("iptables -d" or such), no kernel modules (I didn't find any "iptables.ko" or similar). So my question is: how can it work if there isn't an "active" component?If iptables.tcz and ipv6-netfilter-KERNEL.tcz extensions are installed, then your system has the capability of creating a firewall. However, no firewall is created until you configure one (either manually or using some helper script/application).
$ sudo iptables -nvL
Chain INPUT (policy ACCEPT 12688 packets, 10M bytes)

Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)

Chain OUTPUT (policy ACCEPT 9551 packets, 7421K bytes)
pkts bytes target prot opt in out source destination
It looks like I found a solution. These packages must be installed in order to get a correctly running virt-manager:
virt-manager.tcz
polkit.tcz
gtksourceview.tcz
gtksourceview-gir.tcz
libsoup.tcz
Probably they should be considered as dependencies since they're mandatory to run virt-manager without errors.
gnome-boxes seems much easier to use to me...
I have not found the need to load polkit, gtksourceview or libsoup - virt-manager does however need gtk-vnc-gir and
spice-gtk-gir to connect to a running vm, although it still gives an error message.
Hi core.dump
From:
http://tinycorelinux.net/11.x/x86/tcz/iptables.tcz.info
It appears the x86 version includes includes a basic firewall script not included in x86_64:Code: [Select]Comments: Iptables is the userspace tool to control

Maybe you could try installing filewalld with pip3.6 first to see if it’s really needed?Don't type so fast. You misspelled firewalld. :o
