Build of kvm-37 fails

Hi,

I tried to compile the new kvm-37, and got the following errors:

Excuse me, but I have the same problem with FC6, AMD, 64-bit, kernel 2.6.19.

I don't understand, where should I put the file you attached ?

Hi Avi,

I had the same problem on a laptop with Core2 T7200 @ 2.00GHz running ubuntu with kernel 2.6.20

Going in the kvm-37 source directory and applying the patch with

patch -p1 <hrtimer-compat.h

fixed the compilation problem for me but the VM I've tried crash with

exception 6 (0)

They runned fine with kvm-36 but now they crash even with -no-kvm.

I did further tests after I saw the bug report about the crash related to smp: I was running my vm with -smp 2. If I remove this option, they run fine.

The patch fixes build problems, however the modules won't load properly, I don't know if this is a seperate issue or not.

kernel is ubuntu feisty 2.6.20-16-generic

kvm.ko fails to load due to a 64 bit division, see:

This issue is fixed by Qing's patch to hrtimer migration yesterday, but it is not in yet given that the comments is not properly in. Eddie
