Hi, thanks for the hint, this brought me to a (IMHO) good way to accomplish this. When using FreeBSD as domU and configuring the kernel in the domU config file (rather than using pygrub) it's possible to append kernel parameters, by defining them in the variable 'extras' within the domU config file. With 'kenv' I can read them from within the bootet domU, so this should be just a simple shell script to setup all parameters. Currently I'm not sure where this script should hook into freebsd's internas. The greatest thing would be having a 'rc.conf' parameter to enable configuration from the kernel parameters. Setting this to 'true' would simply fire up the shell script to do all the stuff. Any suggestions or hints on this???
