Re: Virtualisation: Network problems

Hallo Chris,
I am writing in English, so that everybody can understand it.

Hi Gottfried,
is virtlogd running?

I am not sure how it is/was started, but it is running on my system.

#+begin_src sh
ck@beehive ~  $ ps -ef | grep virtlog
root       986     1  0 17:34 ?        00:00:00
/gnu/store/v53l9k5badh84mf6arhhk76f0pa6ly46-libvirt-8.6.0/sbin/virtlogd
- -f /gnu/store/7sd588q79rhdwvq8wypx5n2finsn8gsf-virtlogd.conf
#+end_src


If I do a:

gfp@Tuxedo ~$ ps -ef | grep virtlog

it comes up with:

gfp 5233 5218 0 19:45 pts/0 00:00:00 grep --color=auto virtlog (the word "virtlog" is in red colour)

root@Tuxedo ~# ps -ef | grep virtlog
root 5396 5392 0 19:55 pts/0 00:00:00 grep --color=auto virtlog (the word "virtlog" is in red colour)

I don't know if that means virtlogd is running?

Hi Chris,

thanks for your answer

   does:
~sudo virsh net-list~ show a network?

yes, it shows a network: ("ja" means yes)

gfp@Tuxedo ~$ sudo virsh net-list
   Name      Status   Automatischer Start   Bleibend
----------------------------------------------------
   network   Aktiv    ja                    ja

Hello,
does ~sudo virsh net-list~ show a network? I remember having some issues
which I never solved "the guix way", only
manually.

If virsh doesn't show a network, you can try (locate a
=default.xml= on your machine):

#+begin_src sh

    sudo virsh net-define
/gnu/store/47s1cs65izld791m38aa461s02q5ngb7-libvirt-8.6.0/etc/libvirt/qemu/networks/default.xml
    sudo virsh net-autostart default
    sudo virsh net-start default

#+end_src


Obviously I would prefer a cleaner way, but I haven't looked further
into this yet. If anyone knows the answer, I would appreciate it.

PS: Just for completeness, the =default.xml= looks like this:

#+begin_src conf

    <network>
      <name>default</name>
      <bridge name='virbr0'/>
      <forward/>
      <ip address='192.168.122.1' netmask='255.255.255.0'>
        <dhcp>
          <range start='192.168.122.2' end='192.168.122.254'/>
        </dhcp>
      </ip>
    </network>

#+end_src

Hi Gottfried,
is virtlogd running?

I am not sure how it is/was started, but it is running on my system.

#+begin_src sh
ck@beehive ~  $ ps -ef | grep virtlog
root       986     1  0 17:34 ?        00:00:00
/gnu/store/v53l9k5badh84mf6arhhk76f0pa6ly46-libvirt-8.6.0/sbin/virtlogd
-f /gnu/store/7sd588q79rhdwvq8wypx5n2finsn8gsf-virtlogd.conf
#+end_src

PS: I too am German, so I understand.
PPS: I even use a Tuxedo too! Aura 15 Gen2, pretty happy with it (:
