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: http://wiki.centos.org/Repositories 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 Thanks, Daniel [1] http://kvm.qumranet.com/kvmwiki/Virtio?action=fullsearch&context=180&value=virtio&titlesearch=Titles [2] http://sourceforge.net/project/showfiles.php?group_id=180599&package_id=267943
