Has anyone successfully compiled the latest UML with either MDK 9.0 or RH 8.0. I get compile errors with either.

There is a serious problem with the MDK 9.0 kernel which causes it to hang in less than an hour if you start running UML. (I reported it, got no response and have switched to Redhat). I highly recommend this approach to building your own UML: http://umlbuilder.sourceforge.net/umlcustom.shtml Roger |

We ship O(1) scheduler, so you have to use the forward_pending_sigio fix, or your _guest_ kernel will hang sometimes. > I highly recommend this approach to building your own UML: > > http://umlbuilder.sourceforge.net/umlcustom.shtml Thanks, that's very interesting. I was thinking about hacking Red Hat Kickstart to do massive installs of UMLs some time in the future, but this seems to exist already. -- Pete |

Will it > be soon? O(1) was shipping since RH 7.3, I think. Basically everything that had 2.4.18 based kernel has it. Since the unified errata 2.4.18-17, 7.1 and 7.2 got O(1) too. The fix for the UML itself is not available yet, I just commited it a couple of days ago. So, kernel-uml-2.4.18-17.8.0 hangs too. I basically stole forward_pending_sigio from 2.5, where O(1) is standard. Once again, it's different from what you had in MDK, because guest would hang, not host. -- Pete > > I don't actually run the UMLs for any length of time, since I am > developing UML Builder, and basically do an install and check they > work, before making more "improvements". > > However I do regression testing which involves installing every > single supported distro (in parallel for a laugh) and the last > run was ok. > > > Thanks, that's very interesting.

In general, it would be nice if the installer ran properly under UML. For example, testing kickstart configurations without a spare test box would make my life significantly easier.

Hello again, so in the past few days I moved all of user mode linux stuff fro SuSe Linux to Red Hat 8.0. Went pretty well too, except now I have the problem, that I cannot seem to get uml_net to work anymore. I want to of course use it to invoke several UMLs and easily set their IPs etc. so I do not have to do this manually, this is also kind of silly to do, when they all run in detached screens. Under SuSe this worked fine, Red Hat 8.0 it does not: uml_net never seems to get invoked. I made a shell wrapper for it to echo the args to a file when it gets invoked and then invoke the real binary. The rpm installed it in /usr/bin/uml_net allright with suid to root etc. Everything looks fine as usual. So what could the problem be w/ RH 8? Thanks. By the way I have made a Red Hat Root File System for the UMLs which is "well filled" i.e. there is a lot of other libs etc. in it so you can invoke things like ssh, scp, ftp, vi etc. Should I maybe donate this ? Its fairly large of course but its really useful. I could gladly donate it to one of our web sites. I would take some of our specifics back out and then give it away. Love Snoopy |
