Hi Anna,

I'm afraid that I have some bad news for you. Usually KVM versions are
tailored to kernel versions contemporary with them. Version 87 is
supposed to need 2.6.26 kernels and newer, IIRC. So for your 2.6.16 you
should try some of the incipient KVM versions, and if you are lucky
enough, they might work.

Anyway, are you so tied to that specific kernel version?

Regards,
Cristi
