/dev/kqemu is root-only - there should be a qemu group

[Stefano Rivera]

/dev/kqemu has unusable permissions. There should be a seperate group created for qemu use? and the main user added to it. kvm does this.

This bug has existed as long as ubuntu has had qemu support.

I'm reporting it from gutsy/amd64. Aug 2007.

ii kqemu-common 1.3.0~pre11-5 Common files for the QEMU Accelerator module
ii kqemu-modules-2.6.22-10-generic 1.3.0~pre11-5+2.6.22-10.30 kqemu modules for Linux (kernel 2.6.22-10-generic).
ii kqemu-source 1.3.0~pre11-5 Source for the QEMU Accelerator module
ii udev 113-0ubuntu7 rule-based device node and kernel event manager

$ ls -alhF /dev/kqemu
crw-rw---- 1 root root 10, 63 2007-08-27 15:50 /dev/kqemu

OTOH, kvm creates a kvm group, qemu should do that, too.
$ ls /dev/kvm -alhF
crw-rw---- 1 root kvm 10, 232 2007-08-27 06:54 /dev/kvm

Confirm it.

I use this file /etc/udev/rules.d/60-kqemu.rules
content: KERNEL=="kqemu", NAME="%k", MODE="0666"

$ ls -alhF /dev/kqemu
crw-rw-rw- 1 root root 10, 61 2008-05-08 20:08 /dev/kqemu

[Morten Siebuhr (msiebuhr)]

I use the following in my setup:

/etc/udev/rules.d/60-kqemu.rules
KERNEL=="kqemu", NAME="%k", GROUP="libvirt", MODE="0660"
