Virtualisation: Network problems

Virtualisation: Network problems

[Gottfried]

[-- Attachment #1.1.1: Type: text/plain, Size: 2955 bytes --]

Hi Guixers,

Basic details of my Virtualisation setup:

Name: QEUMU/KVM
Libvirt URL: qemu:///System
Autoconnect yes
-------------------------------------
Network selection
It gives me 3 options:

1. I added a virtual network
	Name: network
	Device: virbr0 is there
	IPv4 configuration is there

Details:

<network>
   <name>network</name>
   <uuid>e324aabf-6ad4-4407-9028-82c96be96e0c</uuid>
   <forward mode="nat">
     <nat>
       <port start="1024" end="65535"/>
     </nat>
   </forward>
   <bridge name="virbr0" stp="on" delay="0"/>
   <mac address="52:54:00:16:e9:74"/>
   <domain name="network"/>
   <ip address="192.168.100.1" netmask="255.255.255.0">
     <dhcp>
       <range start="192.168.100.128" end="192.168.100.254"/>
     </dhcp>
   </ip>
</network>

2. Bridge device
3. Macvtap device

I guess the 1. option is the one I need. May be I made a mistake in 
adding a virtual network
-------------------------------------------------------------------

When I want to set up the QEMU/KVM network connection for the VM
and I want to run the last step(the 5/5 step) of installing an iso
it says:

Installation konnte nicht fertiggestellt werden/
Installation could not be completed:
Failed connect socket to
'/var/run/libvirt/virtlogd-sock':
No such file or directory
-------------------------------------------------------------------
Installation konnte nicht fertiggestellt werden: «Failed to connect 
socket to '/var/run/libvirt/virtlogd-sock': No such file or directory»

line 4442, in createXML
     raise libvirtError('virDomainCreateXML() failed')
libvirt.libvirtError: Failed to connect socket to 
'/var/run/libvirt/virtlogd-sock': No such file or directory
--------------------------------------------------------------------


But running the last step:

Failed to find a suitable default network
-----------------------------------------------

What are the problems here?
Any suggestions?

Gottfried

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>

Hi Chris,

thanks for your answer

  does:

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

Hi Gottfried,
is virtlogd running?

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

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

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 Gottfried,
I just looked at your system config again and compared it to mine. You
are missing the virtlog service. See =Virtlog daemon=[1]

#+begin_src scheme

(service virtlog-service-type
         (virtlog-configuration
          (max-clients 1000)))

Hi Chris,

thanks a lot.
Now it is working.
I am happy/ich bin glücklich.

So at least I have a VM and installed Tails.

Problems occured in using Tails.
I wanted to play around to get a full screen e.g. and my laptop stopped 
after using the key contr + L and contr + S (this was suggested by Tails 
to get the mouse running, because the mouse was not working any more)
I had to start my laptop again.
But that's another problem, it isn't a Guix question.
I have to find out answers somewhere else
or
if a Guixer is using Tails in a VM, he could help me to set everything up.

Answering a bit late (and only this question, since I know nothing about
virtualisation): It means that virtlogd is not running. It shows only
the process you started, which is "grep", with "virtlog" as a parameter.

As an example:
$ ps -ef|grep shepherd
root         1     0  0 11:37 ?        00:00:01 /gnu/store/cnfsv9ywaacyafkqdqsv2ry8f01yr7a9-guile-3.0.7/bin/guile --no-auto-compile /gnu/store/cdc1gzbp3q15kdiwn2i5j3437jwx61ac-shepherd-0.9.2/bin/shepherd --config /gnu/store/17vm5kngzkp3cvp0difp1plxm3dzp49k-shepherd.conf
andreas   9255  1334  0 15:31 pts/1    00:00:00 grep --color=auto shepherd

So there is one line about grep, of no interest; and one line showing that
the thing I am interested in, in this case shepherd, is running.

It's cosmetic, but the standard trick here is to type:

  $ ps -ef | grep '[v]irtlog'

(or any other letter — 'virtlo[g]' also works if you remembered 
too late :-)

That pattern won't match itself, so grep won't show itself.

Kind regards,
