Hello Guix!

Unable to create any VMs by installing from any ISO file.

The virt-manager gives out the following error:

I get the same output for `ls /sys/fs/cgroup/unified/`. But as shown in
the error, the virt-manager is searching the directory
"/sys/fs/cgroup/unified/machine" (not "/sys/fs/cgroup/unified/"), which
does not exist. o.O

So, I've experienced this too. Even though this is a cgroup thing, I'm
pretty sure this isn't an issue with Linux.

I've tried reverting the changes in [1], and that seems to solve the
issue. Unfortunately, I don't have any insight in to what's different
between the problematic 5.5.0 release, and the working 5.4.0 release.

So, by reverting changes, do you mean you patched and made a new
commit?

Thank you!

Hello Guix!

I posted the bug on libvirt mail list few days ago (https://www.redhat.
com/archives/libvir-list/2019-July/msg01309.html). It appears the bug
has now been fixed (https://github.com/libvirt/libvirt/commit/759bf903a
6c24a8efa25c7cf4b099d952eda9bd3).

Could anyone please update the libvirt package/service to this latest
build?

Thank you!

Regards,
RG.

I will do so swiftly since I updated libvirt to the 'broken' version 
(although I never had any troubles like yours).  Thank you for 
reporting this upstream.



A personal note: I find this new wave of 'ATTENTION REQUIRED' messages 
quite the opposite of motivating and pleasant.  I'm honestly not sure 
what result you expect from them.  I fear it may backfire.

You are very welcome to contribute patches yourself!  I don't mean 
'patches or GTFO', I mean 'please dive in, the water's great'.  The 
reviewers don't bite.  You don't need to be a programmmer; I'm not.

You've been part of our discussions for a while, you obviously care 
about Guix and Free software, and particularly about certain Gnome and 
'desktop-demographic' packages that are clearly under-maintained or 
even missing because we're missing people like you.  Learning to create 
and maintain them yourself is hardly more work than trying to herd 
volunteers like this -- and a hell of a lot more fun.

Kind regards,

T G-R

I have applied ‘your’ patch in 
41097b2dee9367974c6dd16ac1ba2ee945457237.

I'm closing this bug for now.  However, could you update and 
confirm that this actually solves the problem?

About that, it appears I misunderstood the patch. That recent build was
not to fix the bug I reported. Anyway, I have been told by one of the
libvirt maintainers (pavel) that they are working on a fix for the bug
I reported.

So once I come to know about the new patch, I will update you and this
mail list. :)

Yeah, sorry about that. It was not intentional. I thought that sending
replies directly to `#bug <at> debbugs.gnu.org` will not use the subject
line, so just went with something top of my head. I will defer to do
this, moving forward. :)

RG.

Oh Shoot! I just saw your previous reply and replied to it. Sorry for
the delay. Anyway that patch fixes something, so good.

You do not have to close the bug. I will update this mail list once I
receive the correct patch. :)

As version 5.7.0 has been released, I tried updating to that. There
seems to be some issue with the configuration for the socket file, but
even avoiding that, it doesn't seem to resolve the issue with the
cgroups.

For now, I've switched more permanently back to 5.4.0.

This bug is consistently reproducible.  I've found an upstream bug
report that is very similar to what we're seeing here, so I've left a
comment telling the libvirt maintainers that Guix is also seeing a
similar issue:

https://bugzilla.redhat.com/show_bug.cgi?id=1751120

In the meantime, should we revert to version 5.4.0 in Guix?  I'm not
sure if there are any security vulnerabilities between 5.4.0 and the
most recent release, but this bug is currently preventing me from
creating any VMs at all in Guix using virt-manager, which is pretty bad.

Yes! (which is why I originally updated this package):

 v5.5.0 (2019-07-02)
   Security
       api: Prevent access to several APIs over read-only 
       connections
           Certain APIs give root-equivalent access to the host, 
           and as
           such should be limited to privileged 
           users. CVE-2019-10161,
           CVE-2019-10166, CVE-2019-10167, CVE-2019-10168.

 ­ https://libvirt.org/news.html

It might be easy to backport.  I didn't try, and I no longer use 
libvirt myself.

What's weird (maybe; I haven't kept up with the thread) is that I 
used libvirt 5.5.0 (and yes, it was 5.5.0) for a while without 
problems.  I don't remember whether I created any *new* VMs, 
though.

Kind regards,

T G-R

Upstream has made a patch, which supposedly fixes the issue on Fedora
systems.  However, I applied it to a local checkout of Guix and tested
it, but it didn't fix the issue for me.  Perhaps that upstream bug and
this bug are slightly different?  Anyway, I've updated the upstream bug
report with information that hopefully will be useful to them.  We'll
see how it goes.

The original upstream bug report has been closed, but it seems likely it
was for a different issue, since it didn't fix the issue in Guix.  At
upstream's recommendation, I've opened a new bug report specifically for
this problem here:

https://bugzilla.redhat.com/show_bug.cgi?id=1760233

I've given them detailed instructions, and a pre-made Guix VM that
demonstrates the bug, which will hopefully help them investigate.  Stay
tuned!

Hi,

This bug can be easier to fix than we thought. :-D

As a workaround, you only have to execute:

$ sudo mkdir /sys/fs/cgroup/unified/{machine,system,user}

The folders should be created at libvirtd start, probably manually with
some extra cgroup magic that I don't understand yet, but this works
well and new machines can be created.  I'll take a look this week into
the libvirtd service if nobody takes it first, as this is quite trivial.

Best regards,
Miguel

Hello again,

The two patches attached create the cgroup directory needed and remove
the warning for the ip binary missing.  Still the following errors
are emitted to the log. 

--------------------8<-------------------
error : virConnectGetCPUModelNames:1109 : this function is not supported by the connection driver: virConnectGetCPUModelNames
error : virConnectGetAllDomainStats:11705 : this function is not supported by the connection driver: virConnectGetAllDomainStats
error : virCgroupSetValueRaw:473 : Unable to write to '/sys/fs/cgroup/unified/machine/qemu-1-Guix.libvirt-qemu/tasks': No such file or directory
error : virCgroupRemoveRecursively:2383 : Unable to remove /sys/fs/cgroup/unified/machine/qemu-1-Guix.libvirt-qemu/ (16) 
-------------------->8-------------------

The last two may indicate there may be lurking another bug in the
cgroups configuration, but at least the machines can be created and
started/stopped seamlessly.  What do you think?

Happy hacking!
Miguel

With the patch you submitted upstream (not the patches you attached to
your previous email here), I can confirm the issue is fixed for me, and
that I do NOT observe the errors you mentioned above.

I see the patch was incorporated into Guix master in commit
aa1f0896fb15a0bdcc5474839c8afdbb2520d603.  That is good, and I think
this issue can be resolved.  If nobody follows up in a few days' time,
let's close the bug report.

Regarding your other patch in this thread to find the "ip" program at
run-time, could you open a new bug report or patch (via
guix-patches <at> gnu.org) for that?  It seems unrelated to the issue at
hand.

Thank you for your help,

Sorry, I did not send the email here.

I created 38032 on guix-patches and Ludo’ applied them.

It was included in that patchset and it was unrelated, yes.  On
master it's commit 2dfb9ba406.

I've been using the patches now on master this week and I have a really
annoying problem: the mouse is drawn on top of the vm screen.  This
one is unrelated too, so I should open a new bug, maybe to
virt-manager...

Thank you too, as you reported upstream and provided a great test
environment, which will help them to test my solution or find better
ones. :)

Happy hacking!
Miguel

Looks like this issue can be closed.
I can't reproduce the bug. Upstream fixed it in libvirt 5.10, so
we'll be able to remove Miguel's patch when we upgrade libvrit.
