We have occasionally seen trouble with virt-builder and virt-customize which are using a smallish virtual machine. In Fedora 28+ I have had to increase the memory available to 1G (from 500M previously, note there is no swap) to get package installation to work reliably.

No idea whether rewriting dnf has helped. I'm not clear which version of dnf is the rewritten one. > Could a look into microdnf be a thing for me? For Fedora/RISC-V, in the early days while we were getting all the dependencies for full dnf ready, we used ‘tdnf’ which is another of these cut down solvers (written in C IIRC). I wouldn't recommend that particular program as it has many shortcomings compared to regular dnf. I don't think we tried microdnf however. I think a more productive way to resolve this will be to try to diagnose what's consuming memory. You can probably do this by getting dnf (or python?) to core dump when it runs out of memory, then examining the core dump file for strings to see if you can identify what data is consuming the memory. Another way would be to use an instrumented malloc implementation such as https://github.com/memtt/malt Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones Read my programming and virtualization blog: http://rwmj.wordpress.com Fedora Windows cross-compiler.

I've not seen issues with it running on ARM devices with 512 Mb of RAM, and there are some that run it on devices with 256Mb but that tends to be a minimal image with no graphics ___ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org
How much is dnf's minimum memory requirement?
What are dnf’s minimum memory requirements? It came as a surprise to me that a simple `dnf check-update` is getting OOM’ed by the kernel on a (ok, fairly small) 512MB VM. [root@node ~]# dnf check-update Killed [root@node ~]# free -h totalusedfree shared buff/cache available Mem: 480Mi 137Mi 292Mi 0.0Ki50Mi 329Mi Swap:0B 0B 0B [root@node ~]# cat /etc/os-release |grep -i pretty_name PRETTY_NAME="Fedora 29 (Server Edition)” [root@node ~]# dnf --version 4.0.4 Installed: dnf-0:4.0.4-1.fc29.noarch at Tue 30 Oct 2018 03:38:30 PM GMT Built: Fedora Project at Mon 15 Oct 2018 12:00:52 PM GMT Installed: rpm-0:4.14.2-1.fc29.x86_64 at Tue 30 Oct 2018 03:37:40 PM GMT Built: Fedora Project at Wed 22 Aug 2018 08:07:47 AM GMT According to [1], 1GB is required for a Fedora (desktop?) install but right underneath is a note that says only if I want to install it with lots of packages selected upfront. With F28 Server (ships with dnf 2.7.5) this worked perfectly fine on an equally sized VM. Anyway, is memory consumption a thing with the new libdnf-in-C++ efforts? Could a look into microdnf be a thing for me? Any advice appreciated.
