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". -- Jason Wong System engineer Cluster Technology Limited Email: hcwong@clustertech.com Direct Line: (852) 2655-6129 Tel: (852) 2655-6100 Fax: (852) 2994-2101 Website: www.clustertech.com ------------------------------ ************************************************************************** The information and attachment contained in this e-mail originating from Cluster Technology Limited is confidential and intended solely for the specified addressees.
