[Qemu-devel] Help debugging a regression in KVM Module

[Peter Lieven]

Hi,

some time a go I stumbled across a regression in the KVM Module that has been 
introduced somewhere
between 3.17 and 3.19.

I have a rather old openSUSE guest with an XFS filesystem which realiably 
crashes after some live migrations.
I originally believed that the issue might be related to my setup with a 3.12 
host kernel and kvm-kmod 3.19,
but I now found that it is also still present with a 3.19 host kernel with 
included 3.19 kvm module.

My idea was to continue testing on a 3.12 host kernel and then bisect all 
commits to the kvm related parts.

Now my question is how to best bisect only kvm related changes (those that go 
into kvm-kmod)?

Thanks,
Peter
