Hi I really like UML. I have been experimenting with it in TT mode for sometime now, and I've have to admit its very very impressive technology. I would like to use it in SKAS mode with the SYS-EMU patch, for the obvious reasons. However I have to admit, I'm somewhat stumped on finding a stable and fast kernel combination. There are so many patches, and so many options popping up all the time, I'm having great difficulty keeping up with the speed of UML developement. Keeping up with UML seems like a full time job! I need to use a version 2.6 host kernel (for some commercial kernel modules for my work station.) I don't think it matters on the guest kernel, so long as it is stable and fast! Any suggestions ? Thank you very much J.Lackman |

It is stable, but pretty slow (probably my stupidity). HTH Sunny Dubey |

Other ones to think to: 2.6.9 vanilla - does not work on a 2.6.9 host and misses the security fixes. 2.6.9-bb[23] - has the security fixes, but one serious bug in certain situations - going to be fixed in -bb4. 2.6.10 vanilla when it will get out - I hope to get all this fixed. > (probably my stupidity).

I have 2.4.27 with 2.4.27-um1 for the guest and there are no problems with speed. 2.4.26 with the 2.4.24-um1 patch and the cmpxchg patch is solid and fast with the same host. |

Keeping up > with UML seems like a full time job! That's true. And the official project page itself is pretty much lagging behind, at least when it comes to 2.6 guests (what most newbies would want, i guess), it even does not mention Blasorblades uml site. What about a -stable patch only containing bugfixes for the vanilla kernel in addition to the -bb (devel) patch? > I need to use a version 2.6 host kernel (for some commercial kernel > modules for my work station.)

Blaisorblade said a lot on guest kernels, and on hosts there's only the skas3-v7 (host-skas3-2.6.7-v7.patch works on 2.6.8.1), it includes all you need (times of adding sysemu patches are over). Skas seems do develop not as fast as guest (i'd say 1 patch/month ;-) I used 2.6.9 umls (vanilla) on 2.6.8.1-skas3-v5, that was pretty stable. Now i use 2.6.9-bb3 on 2.6.9-skas3-v7 and have some minor issues, probably because of -bb, not -skas3-v7. /nils. -- there is no sig. |

I'll later add a true development thing, if and when I need it. However, given the size of the security fixes, marking it as "stable" was impossible. They had been on the incrementals page of Jeff. One patch was so big I was astonished it wasn't buggy - in fact now it was tested it *is* buggy, even if you need special things (realtime signals) to trigger the bug. It's the bug triggered by Mysql Christopher Aker has experienced, causing zombies in his setup. > > I need to use a version 2.6 host kernel (for some commercial kernel > > modules for my work station.)
