Qemu error and kqemu not enabled

flebber · 10-21-2007, 05:03 PM

Hi I have just set up QEMU on suse 10.3 following the guides from http://en.opensuse.org/Qemu and http://en.opensuse.org/Qemu_with_kqe...module_support and http://fabrice.bellard.free.fr/qemu/kqemu-doc.html however each time I start qemu I receive these errors is there a way to permanently get rid of them ?

Code:

flebber@focus:~> qemu -m 256 -hda myharddisk.qcow -cdrom /dev/cdrom -boot c -localtime
Could not configure '/dev/rtc' to have a 1024 Hz timer. This is not a fatal
error, but for better emulation accuracy either use a 2.6 host Linux kernel or
type 'echo 1024 > /proc/sys/dev/rtc/max-user-freq' as root.
You do not have enough space in '/dev/shm' for the 256 MB of QEMU virtual RAM.
To have more space available provided you have enough RAM and swap, do as root:
umount /dev/shm
mount -t tmpfs -o size=272m none /dev/shm
Or disable the accelerator module with -no-kqemu

Also after following guides to enable kqemu support I still find that when I do ctrl+alt+2 and info kqemu it is still telling support is disabled.

What can I do to resolve these problems ? and/or are there other guides that are recommended reading ?

Did you do this bit:

Quote:

umount /dev/shm
mount -t tmpfs -o size=272m none /dev/shm

?

Yes. but after a reboot you must do it each time.

Change your /dev/shm entry in /etc/fstab to:

Code:

tmpfs /dev/shm tmpfs defaults,size=272m 0 0

and it should survive a reboot.
