Re: Question on stopping KVM start at boot
Hi Dustin, - snip - Where shall I add "-b" option? Thanks modprobe -b says "respect the blacklists". See: * http://manpages.ubuntu.com/manpages/lucid/en/man8/modprobe.8.html -b --use-blacklist This option causes modprobe to apply the blacklist commands in the configuration files (if any) to module names as well. It is usually used by udev(7). So you would change the lines that say "if modprobe ..." to "if modprobe -b ..." Your advice works for me. Thanks B.R.

Thanks If I'm not wrong, there. That "if" is loading the module and sees the return code to give an error if it fails to load.

Quoting Bitman Zhou : - snip - Please what further command I have to run in order to activate the new blacklist.conf ? For Ubutnu, you can just use update-rc.d sudo update-rc.d kvm disable to disable kvm and sudo update-rc.d kvm enable to enable it again. Tks for your advice. B.R.

Hi Dustin, Thanks for your advice. - snip - Or you can edit the /etc/init.d/kvm or /etc/init.d/qemu-kvm init script and add the "-b" option to the modprobe calls in there. $ cat /etc/init.d/kvm | grep modprobe No printout $ cat /etc/init.d/qemu-kvm | grep modprobe if modprobe "$module" . if modprobe "$module" then log_end_msg 0 else log_end_msg 1 exit 1 fi ;; Where shall I add "-b" option?

Hi there, Unfortunately, the /etc/init.d/kvm and /etc/init.d/qemu-kvm init scripts in previous Ubuntu releases (9.10 and earlier) didn't respect the module blacklists. I have corrected this in Ubuntu 10.04 by using modprobe -b. Thus for Ubuntu 10.04 forward, you should be able to use the blacklist appropriately. For other release, you can disable the init script entirely as the other responder wrote. Or you can edit the /etc/init.d/kvm or /etc/init.d/qemu-kvm init script and add the "-b" option to the modprobe calls in there. -- :-Dustin -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

So you probably must not run it on start up or teach it how to read the blacklist. Perhaps this is more appropriate to ask on an ubuntu-specific mailing list, since this is an ubuntu problem.
