Does anybody have experience running recent releases of SuSE (8.1 or SLES= ) on UML? I've done some preliminary experiments but have hit a brick wall so far. Anselm --=20 Anselm Lingnau ...

You can use UML Builder to install Suse 7.2 or 7.3 into UML. http://umlbuilder.sourceforge.net/ It doesn't support Suse 8 or above yet as I don't have a copy and Suse don't have ISOs for download.

And I don't think this could possibly be attributed to devfs.

UML performance is pretty much identical to the host, except for making system calls, which do take a hit depending on several factors (skas vs tt mode, how much UML kernel code is executed, how much host kernel code also has to be executed). The thing I have seen hitting performance the most is how many daemons and other "helpful" tools are run by default on startup. This is especially bad if you do a full install. The other fun thing that happens is shortly after you start your UML for the first time, anacron goes off and runs various housekeeping tasks such as building the slocate database, indexing the man pages etc. Due to the high number of system calls these really bad affect interactive performance. But at the end of the day you are right. If you are running the same set of processes, there should be no appreciable performance difference. Roger |

I have 8.0 running inside UML with only a few glitches. I installed it inside bochs and fixed it up to work in UML afterwards. The largest problem right now is YaST2 behaving strangely. It seems to go into an endless loop of segfaults orsomething like that. I'll have to get it debugged a bit better at some time. -- Med venlig hilsen Christian Laursen |

Uhm, mind you, not using the installer, but basically by doing rpm --root ... -ivh *.rpm and running a customizing script to fix up inittab etc. It should be possible to also do it in a 'clean' way using the auto-installer feature, but this wasn't necessary for my needs. My colleagues tell me I'm doing it wrong thus, tough, it works ;-) What brick walls have you hit?
