This article is outdated but it says that qemu is not needed. I would be surprised if it was needed now. I have used virt-manager for Xen and didn't need qemu. If I attempt to install virt-manager and kvm it doesn't pull in qemu for me. So, my conclusion would be that qemu isn't needed. The qemu-kvm/qemu-kvm- img is only necessary if you want to use an image file. It is just able to create the image file, it's only a small tool from the whole qemu package. You certainly don't need the whole package. qemu is on lose terms "the same" as KVM - e.g. it is another hypervisor/emulator. You just need one. Until you get better help from someone running kvm on 5.4, have you temporarily disabled SElinux to see if that makes it work? If it still doesn't work I guess there's something wrong with your setup. There's also a Virtualization Guide for RHEL and I expect it to include KVM instructions now that KVM is part of RHEL. The 5.4 documents are not yet on the CentOS site, so you have to check on the RH site for it. Kai -- Kai Schätzl, Berlin, Germany Get your web at Conactive Internet Services: http://www.conactive.com
