PostPosted: Mon Mar 03, 2014 1:38 am    Post subject: Genkernel Kernelpanic Reply with quote

I just tried to install gentoo and followed the tutorial, i decided to use a genkernel and the default partitions (/dev/vda1 boot ext2, /dev/vda2 swap, /dev/vda3 root ext4).
I'm using a genkernel and the default grub config but i get a kernel panic everytime i try to boot
The last line is: "Determing root device...."
Has anyone an idea how i can fix that?

When i insert real_root=/dev/vda3 and rootfstype=ext4 it tells me that /dev/vda3 is not a valid root device, but i have ext4 support in the kernel.




Here my grub config:

Which hypervisor are you using? Are you sure it is reporting the devices as virtio?

Thanks a lot, that was the hint i was searching for, i use kvm the problem got solved by compiling ballooing in the kernel.

Now i have another problem but i think it's not worth an extra toppic: The update of python 2.7 crashes with "make: *** [sharedmods] Error 1
"

The emerge info for that package:
Code:
