Bug#607391: qemu-kvm: /dev/kvm should have group id kvm

One was: KERNEL==kvm, MODE=0660, GROUP=kvm ACTION==add|change, SUBSYSTEM==dmi, KERNEL==id, RUN+=/bin/sh -c 'grep -q vmx /proc/cpuinfo /sbin/modprobe kvm-intel; grep -q svm /proc/cpuinfo /sbin/modprobe kvm-amd' The other was: KERNEL==kvm, MODE=0660, GROUP=kvm but had kvm_intel in /etc/modules.

Lenny (and not Squeeze) also had a entry KERNEL==kvm, GROUP=kvm in /etc/udev/rules.d/91-permissions.rules, which might have covered over latent problems. And the only place I can think of where that file may come from is kvm package v. 85 or nearby, which were present in backports for some time, and for which I don't have any upgrade paths. Hmm, it looks like I started with Etch kvm-72, dallied with upstream from qemu-kvm-0.10.5 to 0.12.3, backports as soon 0.12.3 hit there, then back to official with Squeeze. Really, anything could have happened while I was installing from upstream sources ...

Maybe I will be able to come with some automatic solution, but I'm afraid it's too late for squeeze, -- I don't want to mess up with config files risking to create more serious breakage. Hope that helps. I can't speak for Richard's case, but as happy to regard my own as self-inflicted.

Bug#607391: qemu-kvm: /dev/kvm should have group id kvm
tags 607391 + moreinfo unreproducible thanks [Somehow I didn't see the bugreport - neither of the messages reached me. Dunno why] Richard Kettlewell wrote at Mon, 07 Feb 2011 22:12:18 +: There is actually a file in /lib which can help achieve this. I used these commands: # cp /lib/udev/rules.d/60-qemu-kvm.rules /etc/udev/rules.d/ # udevadm test $(udevadm info -q path -n /dev/kvm) There is also a section in the postinst which references a nonexistent rules file, which be a failed attempt to do the same. The lines you refer to is a compensation for a very old udev rules file which previously (in pre-historic times) has been in /etc/udev/rules.d/. Sure thing it does not exist in modern systems. But the thing is: /lib/udev/rules.d/60-qemu-kvm.rules file is sufficient for udevd to pick that file up, there's no need to copy that file into /etc/udev/rules.d/ unless you want to _modify_ that file. This was the intention when moving stuff from /etc/udev/rules.d/ to /lib/udev/ - in order to be able to modify the rules that comes with each package without worrying about local changes. If a file named the same is present in /etc/udev/rules.d/, that file will be used instead of the one in /lib/udev/rules.d/. So I'm not sure I understand the problem, it all works as intended, on my systems and on many other systems all over the world. Maybe you have very old udev package (from Lenny?) which does not look at /lib/udev/rules.d at all?

In my case the system was upgraded from lenny, so my guess is that some bit of qemu-kvm doesn't handle the upgrade correctly. I was on squeeze's udev by the point I found the problem, having followed the squeeze release notes instructions on upgrading. I've since purged and reinstalled all the libvirt and kvm packages; the result seems to behave better. ttfn/rjk -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.
