libvirtd requires restart to function

Currently libvirtd does not work without running "sudo herd restart libvirtd". Upon starting virt-manager I can't connect to the socket but if I restart libvirtd it works fine.

I tested the 1.4.0 image in a VM and there is no issue. After that I did a guix pull and reconfigured the system and I have the same issue again in the VM.

Hi,

Christian Miller <miller.christian@proton.me> skribis:

Are there any hints in /var/log/messages as to what goes wrong with

libvirtd when it is first started?

I suspect it’s getting started “too early”.

Thanks,

Ludo’.

Hi,

there is not an error message upon starting it but by stopping it:

Jun 14 23:52:18 localhost shepherd[1]: Stopping service libvirtd...

Jun 14 23:52:18 localhost libvirtd: 157: error : virGDBusGetSystemBus:99 : internal error: Unable to get system bus connection: Could not connect: No such file or directory

I have added the command output of "grep -i libvirt /var/log/messages" as attachment.

NOTE: That permission denied error on the ISO is happening since I copied /etc/libvirt from my old system. I have 10+ VMs and thought this works as well as of re importing every vm.

PS:

I wanted to create a VM to not taint logs but since I upgraded the VM I just have a black screen. It was a Guix VM installed through the installer with GNOME. I ran guix pull and added spice, libvirt and virtlog to the config. After guix system reconfigure config.scm I know have a black screen upon logging in to the system. This was only after reconfiguring the system. Before it worked normally. I used the ISO that reports a permission denied error in the logs I attached. GDM works fine but after logging it is just a black screen. Also my mouse cursor changes from a arrow pointer to the default cross cursor from x11. I guess something is broken on latest?

Seems that dbus is needed for libvirt, but it is not listed as a

requirement for the shepherd service. I don't use libvirt, but would

you be able to test the following patch?

Hello,

I tested your patch and it works. With the patch virt-manager does instantly connect without any manual interference.

Since this is the first time I did this, just to be sure I did everything correctly, I list how I tested it.

I cloned the git repository

I created a file called libvirtd.patch with your contents

git apply libvirtd.patch

guix shell -D guix --pure

./bootstrap

./configure --localstatedir=/var

make

make check (had 2 errors, authenticate and something else)

after that I executed "sudo -E ./pre-inst-env guix system reconfigure ~/guix/system.cm"

I rebooted the system and launched virt-manager which directly connected.

Best Regards,

Christian Miller

Great! Thanks for going the extra mile testing this, I didn't know how

familiar you were with the Guix development process. We could also

advertise the simpler `guix time-machine` with the branches from [1],

although processing the new patch is not instantaneous (and I don't

think bug reports are scanned for patches).

In any case, I'll try to push it ASAP with some other changes!
