[libvirt] Host local_host running without virtualization hardware acceleration
Hi, I had to reinstall ovirt yesterday and now it seems that it doesn't work anymore. I'm running nightly on Fedora 18. kernel-3.11.4-101.fc18.x86_64 sanlock-2.8-1.fc18.x86_64 libvirt-1.1.4-1.fc18.x86_64 qemu-1.5.1-1.fc18.x86_64 vdsm-4.13.0-93.gitea8c8f0.fc18.x86_64 ovirt-engine-3.4.0-0.2.master.20131104192919.git3b65870.fc18.noarch engine-setup with all-in-one detects hardware virtualization and allow me to configure the system. (it fails detecting engine health status due probably to recent changes in its URL, I'm already looking into it) Once added localhost to the engine, it has been moved to non operational mode saying I don't have virtualization hardware acceleration anymore.

I've found kvm_intel module not loaded. I've created a new conf file for loading it automatically at boot so I've solved on my system. However, what has been changed for not having it loaded automatically as it was done before? -- Sandro Bonazzola Better technology. Faster innovation. Powered by community collaboration.

This is good, but AFAIK this module is not what provides /dev/kvm. Depending on the processor you're using, try checking 'kvm_intel' or 'kvm_amd'. Also make sure both are loaded.

What does ls -lZ /dev/kvm tell you?
Any clue on what may be happened?
No idea, but I'm basing everything on the fact that it worked before the re-install, am I right? Martin

it doesn't existed, now it's working again after modprobe kvm_intel

right. something was loading that module automatically before reinstall and now I needed to create a conf file for having it loaded.

Perhaps it was libvirtd, and in your new setup it's not started automatically on boot? -- Didi

What's your `lsmod | grep kvm` ? If empty, does `modprobe kvm_intel` trigger tail-telling lines on /var/log/message? Dan.
