Maybe a bit OT, but otherwise close to gentoo as well (as we all |
| 2 |
configure our kernels individually ....) (see ps below): |

When I configure my gentoo-server for Linux KVM, how to get the |
| 5 |
clock-issues right, in terms of correctness and performance? |
| 6 |
|
| 7 |
I assume that I am not the only one scratching his head ... but maybe |
| 8 |
some of us simply hesitate to ask ;-) |

HPET, RTC, TSC, blah ... |
| 11 |
|
| 12 |
A new server with a Xeon-CPU tells me: |
| 13 |
|
| 14 |
"kvm: SMP vm created on host with unstable TSC; guest TSC will not be |
| 15 |
reliable" |
| 16 |
|
| 17 |
Ah, ok. |
| 18 |
|
| 19 |
Is that bad? Could I do something? Should I? |
| 20 |
|
| 21 |
My question is // questions are: |
| 22 |
|
| 23 |
Are there any recommended kernel-config-settings for a performant and |
| 24 |
non-drifting KVM-server? |
| 25 |
|
| 26 |
Is there a "best practise"? |
| 27 |
|
| 28 |
What is your experience, your recommendation? |

Maybe it should find its way into the gentoo wiki :-) |

Thanks in advance, Stefan |

ps: yeah, I know, this should go to the linux-kvm-ml in an ideal world. |

We all know that we would end up subscribed to dozens of mailing-lists |
| 36 |
just to get our jobs done .... so pls be tolerant in terms of "what is |
| 37 |
off-topic". thx. |
