Bug 101529 – qemu: Add /etc/modules.d/kqemu for better udev support

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Alexander Skwar 2005-08-06 03:13:18 UTC]

The kqemu installation documentation at
http://fabrice.bellard.free.fr/qemu/kqemu-doc.html#SEC4 states:

If your distribution uses udev (like Fedora), use the kqemu module option
major=0 to have the device `/dev/kqemu' automatically created:

# Load the KQEMU kernel module
/sbin/modprobe kqemu major=0


To do this easily, a /etc/modules.d/kqemu file should be created with content:

options kqemu major=0


After installationb of that file, modules-update should be run.

There is already a sysfs patch to make udev create the device.

[Comment 2 Chris Bainbridge (RETIRED) 2005-11-01 03:36:23 UTC]

The sysfs patch has been removed since 0.7.1-r1. Currently on a udev only system
(no RC_DEVICE_TARBALL in /etc/conf.d/rc) kqemu fails because /dev/kqemu isn't
created. As Alexander pointed out it is necessary to use the argument 'major=0'.

fixed in the separate build

[Comment 4 Colin Macdonald 2006-01-07 17:52:56 UTC]

Doesn't seem fixed to me.  I still had to add major=0 even after I did a udevstart (I assume this would make it reread the /etc/udev/rules files).
