Hi all,

We have just added KVM-66 packages to the CentOS 5 testing repository.
This version of the Kernel Virtual Machine has numerous improvements
over KVM-36, which is currently in CentOS-Extras. One of the notable
new features is support for paravirtualized block and network devices
through the virtio architecture[1]. Currently, only Linux kernel
2.6.25 provides paravirtualized block and NIC  drivers. A
paravirtualized NIC driver is available for Windows[2].

We'd like to hear from current KVM users whether this version has any
regressions for their applications compared to KVM-36. Of course, we
are interested in other bug reports as well!

Information on using the CentOS Testing repository can be found on the
CentOS Wiki at:


The KVM module package is named 'kmod-kvm', and has a dependency on
the userland KVM tool. So, the following command should do the trick,
and pull in all required dependencies:

yum --enablerepo=c5-testing install kmod-kvm
