Do we have a list of supported OSes somewhere? :)
Also, it seems the virHostCPUGetKVMMaxVCPUs function is built
unconditionally, so it might need to be wrapped in HAVE_LINUX_KVM_H.
Have you tried building it on non-Linux?

Introduced in libvirt by:
commit 04e9e1b2a63f4255d6fddbd5990a0a0cde0ccf1b
Author: Richard W.M. Jones <rjo...@redhat.com>
CommitDate: 2008-09-17 14:07:49 +0000
configure.in, src/qemu_driver.h, src/qemu_driver.c: KVM
can determine max VCPUs at runtime (Guido Günther).
git describe: v0.4.4-212-g04e9e1b contains: v0.4.6~17
And in kernel by:
commit f725230af9ea03f6cc6f4a90e87aa428df46ec19
Author: Avi Kivity <a...@qumranet.com>

KVM: Add API to retrieve the number of supported vcpus per vm
Signed-off-by: Avi Kivity <a...@qumranet.com>
git describe: v2.6.25-5338-gf725230 contains: v2.6.26-rc1~1028^2~110
So I think we're safe to drop the redefinitions if we have linux/kvm.h.
