Dear all,
I found that libvirt 0.6.3 seems does not load KVM driver while libvirt
0.3.3 does.
Situation description:
I am using CentOS 5.3, and the kernel I used is 2.6.30.
I downloaded the kernel from kernel.org andcompile it. KVM was compiled
as a module.
libvirt: libvirt 0.6.3, released by Eucalyptus(a cloud computing
infrastructure software which supports KVM as well)
(1) libvirt 0.6.3 does not load KVM driver
No libvirt release has ever loaded the KVM kernel modules. This is
left upto the OS distribution vendor to deal with. In Fedora, the
KVM RPM installs a script that loads them upon boot. I'm not sure
what CentOS does.

Dear Daniel,
Let me clarify, the KVM qemu driver, in my understanding is the part
that responsible for the communication between KVM hypervisor and
libvirt (I think it is in the source code qemu_driver.c).
For KVM kernel module, I have manually use "modprobe kvm" command into
kernel.
Perhaps I should use the term "qemu driver" instead of "kvm driver".
