|
|
Hello
I am trying to install gentoo hardened on a KVM Vserver. I did switch to the hardened toolchain und did a whole system rebuild. So far everything worked without a problem. The only problem is, when I use the hardened kernel, the system does not boot.
There is no output into logfiles, nor can I see the output at boottime.
I tried various .configs; one with gernkernel, one 99% copied from the working vanilla-kernel and one made from scratch. same result
Does anyone have any experience witch such issues? Do you want all the .config files?
[Edit:] sorry, got cut off there!
As previously stated, I have no issues at all, when I am using the vanilla kernel. But using the hardened kernel, even with all the "hardened stuff" disabled results in an unbootable system. I think one of the secutity patches conflicts with my system. Is there any way to find out, what it is? |

This may be a long shot, but I was looking at this page over here ("Setting up grsecurity + gentoo in a VM"), and noticed this part:
Quote: | Make sure you disable Paravirtualized guest support under Processor type and features in any case. Enabling that causes the system to not boot. |

Thanks for sour reply!
The option was disabled in all my Kernels :/
I tried a never version of hardened-sources, no improvement
I will reinstall my system once again tomorrow.... maybe it helps |

If the system boots correctly under vanilla, then the problem is almost certainly related to the hardened kernel itself. A full system reinstall is unlikely to fix things. Please try to obtain the boot output. |
