I need a libvirt daemon running in order to use virt-manager

I want to use virt-manager because I want to use an Ubunu installation as a
virtual machine, for reasons

I see there are 2 different services in gnu/services/virtualization.scm: a
libvirt and a virtlog service

Because I don't now that much about virtualization, could anyone please
give me an example of how I should configure such services in my conf file,
in order to have an Ubuntu desktop ?

Thanks in advance

Hi Catonano,

> I need a libvirt daemon running in order to use virt-manager

You just need to have the libvirt service with the default
configuration, and then you should be able to use virt-manager.  Have
you tried that?

Ok, I reconfigured

virt-manager still can't start:

libvirtError: Failed to connect socket to '/var/run/libvirt/
libvirt-sock': Permesso negato (denied permission)

~$ ls -lhad /var/run/libvirt
drwxr-xr-x 8 root root 4,0K 12 dic 18.43 /var/run/libvirt/

~$ sudo herd status libvirt
Password:
herd: service 'libvirt' could not be found

am I doing anything wrong ?

Just in case you or someone else wants to use libvirt. I think the
service is called libvirtd, and you probably need to make sure you're
user is in the libvirt group.

Thank you Chris !

I managed to launch the GUI client (virt-manager ?) but I found it too
dificult, with too many options to figure out

Maybe had I made sure that my user was in the libvirt group, the experience
would have been different

But I moved to my Fedora desktop and used Boxes. Way simpler

It'd be nice to have Boxes on GuixSD too
Maybe some day I'll send a patch ;-)

It's called "libvirt" !

Also in the "root" group !

In fact, when launching virt-manager, var/run/libvirt/libvirt-sock should
be accessible and it's readable/writable by users in the root group, others
can't access it

So your user needs to be in the root group too !

Happy New Year !

That doesn’t seem right.  This smells like a bug to me.  Users shouldn’t
ever need to be in the root group.

Souldn't they ?
I don't know

All I can suggest is you reproduce the issue.
Reconfigure your system with libvirt, install virt-manager in you profile,
launch your virt-manager and see what happens

Looks like you need to start virtlogd first.
Is this part of the installation of libvirt?

I have this among the services in my configuration

(service libvirt-service-type)

I see now that probably also

(service virtlog-service-type)

should be present

Should it ?

I'm not sure I understand thhe question
I assumed that the libvirt service in my configuration was enough

Thanks

There does not seem to be a service type for this.  Maybe it should be
added.

That’s what I assumed too.  I used libvirt before on Fedora but had not
noticed virtlogd.

There's a virtlog service in gnu/services/virtualizzation.scm

The manual mentions it too

I'm reconfiguring right now, I'll let you know

Ok, now it works

The problem is, now, that the virtual machine seems to be off line

How do I set it up ?

Maybe this is more about virt-manager ?

virt-manager has a way to create networks, I have one called
"vm_network" which uses NAT, I think that might be a default thing, and
it seems to work.

When you create a virtual machine, you should be able to select to use a
network. If I look at an existing machine I have, I see a "NIC ..."
device, which uses the "vm_network".

If you've got all this, it could be that the networking isn't getting
started in the virtual machine...

I discovered that virt-manager has a  "connection settings" section and a
"virtual machine details" section

I fumbled with the 2 and somehow I stumbled into a working configuration,
also along the lines of your suggestions

So now I have a working Ubuntu Xenial installation inside a virtual machine

I'm not sure I'd be able to reproduce this configuration, should I want to
but I guess I have to live with that

It's a progress anyway

Thank you

Great, I'm glad you're making progress :)
