tracepoint undefined symbols?

tracepoint undefined symbols?

[Xavier Gnata]

Hi,

I'm trying to compile kvm-87 on 2.6.30-10-generic #12-Ubuntu SMP.
I get:

and modprobe kvm fails due to these missing symbols.

I'm missing something here...

No, you aren't.  kvm-87 is pretty broken on 2.6.30+ host kernels.  You 
can use qemu-kvm-devel-87 with the modules from 2.6.30, and I'll try to 
fix things up for kvm-88.
