I think I could use some help about how to set up a networing device to be
used as a "bridge" for the libvirt-manager bridged networking

In the manual I found a procedure named static-networking-service but I
have no idea about how to use it

Thanks

The static-networking-service currently does not support setting up
bonding or bridges.  It’s something I need for berlin.guixsd.org,
actually, so I’d be very happy to see this implemented :)

static-networking-service is also limited to IPv4. I wanted to configure 
an
IPv6 address, so I quickly wrote a service for this:

(define (iproute2-shepherd-service config)
   (list (shepherd-service
           (documentation "Run the iproute2 network service")
           (provision '(networking))
           (requirement '())
           (start #~(lambda _
                      (let ((ip (string-append #$iproute "/sbin/ip")))
                        (system* ip "a" "add" "89.234.186.109/32" "dev" 
"ens18")
                        (system* ip "l" "set" "ens18" "up")
                        (system* ip "-6" "a" "add" "2a00:5884:8208::1/48" 
"dev" "ens18")
                        (system* ip "r" "add" "89.234.186.1" "dev" 
"ens18")
                        (system* ip "r" "add" "default" "via" 
"89.234.186.1" "dev" "ens18")
                        (system* ip "-6" "r" "add" "default" "via" 
"fe80::204:92:100:1" "dev" "ens18"))))
           (stop #~(lambda _
                     (display "Cannot stop iproute2 service.\n"))))))

Howdy,

‘static-networking-shepherd-service’ has a number of hard-coded
“AF_INET”.  I’m quite confident that if we make them a parameter in
<static-networking>, we can get IPv6 support.

Would you like to give it a try?  :-)

Hi Julien,

Are you actually using this? Does it simply (static-networking-service)?

TIA - George

Re: static-networking-service

[Julien Lepiller]

I use it like that:  (service iproute2-service-type #t)

You can see my complete configuration on https://lepiller.eu/ma-configuration.html

Hi Ricardo,

Is this still an outstanding wish?

Yes, this hasn’t been implemented yet.

As Julien mentioned, you probably could wrote a service which invokes
shell commands.

From https://debbugs.gnu.org/cgi/bugreport.cgi?bug=28718#8
(WARNING: I remember a syntax error was somewhere in some ‘ip’ command):

--8<---------------cut here---------------start------------->8---
# ip link add bridge0 type bridge
# ip link set dev enp6s0 master bridge0
# ip link up bridge0
# dhclient bridge0
--8<---------------cut here---------------end--------------->8---

In /etc/qemu/bridge.conf (may not required for Libvirt):
--8<---------------cut here---------------start------------->8---
allow bridge0
--8<---------------cut here---------------end--------------->8---

Oleg.

What do you want to do?  It's possible that depending on what you want
to do, you might not need to set up a bridge.

For example, it took me quite a while to figure out how to connect to my
VM from the host machine when using virt-manager.  I thought I had to
forward ports, and I couldn't figure out how to do it.  But it turned
out that the guest was available directly via a local IP address, and I
just didn't realize it.
