https://bugzilla.suse.com/show_bug.cgi?id=1214845 Bug ID: 1214845 Summary: libvirtError: Unable to find 'memory' cgroups controller mount Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: openSUSE Tumbleweed Status: NEW Severity: Normal Priority: P5 - None Component: Virtualization:Other Assignee: virt-bugs@suse.de Reporter: chrisvte@gmail.com QA Contact: qa-bugs@suse.de Target Milestone: --- Found By: --- Blocker: --- After I updated to kernel 6.4.11-1-default, every time I booted a LXC I was getting this error: “libvirtError: internal error: Unable to find ‘memory’ cgroups controller mount” I replicated the installation in a minipc (Intel N5105) and it worked perfectly, so I did a new installation in the first computer (AMD Ryzen 5600G) and, again, I got the same error of the beginning. I tried in other two computers (AMD Ryzen 5900X and Intel i5-1135G7) and I got the same error. If I added “systemd.unified_cgroup_hierarchy=0” to the boot line, the error went away, but it was really unstable (containers stopped working after a while). I usually install the tools of virtualization through Yast (KVM Server and KVM tools). After that I install a few more packages: libvirt-client, libvirt-daemon, libvirt-daemon-lxc, libvirt-daemon-driver-lxc, system-user-libvirt-dbus. Finally, I add the user to groups libvirt, qemu and kvm. Reboot and run.
