Unable to self compile on macOS m1 #111
Description
I have krunvm installed from brew and I'm trying to compile this project with build_on_krunvm scripts. Both of them fail with a different message. At first glance they look like a network issue, but when I run alpine image both apk and curl work fine in alpine and can connect to the internet just fine. So I'm not sure what it is.

Updated krunvm to version 0.2.6 and now it works. It was a bug in the previous version.
slp commentedon Feb 9, 2026
As a reference, the problem was a combination of libkrun/libkrun#513 and libkrun/krunvm#79. I've just released new versions of both to address the problem.

BTW, thanks @pftbest for the issue report!
pftbest commentedon Feb 9, 2026
@slp Thanks! Unfortunately I've run into yet another issue. For some reason removing temporary directories sometimes does not work inside the VM. For example when I try to install some package in debian I get this errors all the time
When I manually look into this directory it seems empty, however when I run
rm -rfcommand it fails and immediately after that there is a file calledcontrolthat automatically disappears after around 5 seconds.I also see a similar issue when compiling linux kernel, it also complains about removing some temporaries.
At this point I'm not even sure this is krunvm fault, maybe I have some software running on the host that creates thiscontrolfiles? I don't see any mention of them in libkrun.EDIT: Managed to read the file, it was created by debian apt-get, it is part of deb package that was extracted into this dir. But for some reason guest doesn't see it, until you try to remove the dir, then it sees it for a couple of seconds.

Could you please create an issue in libkrun to track this one?
