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 that:
# modinfo kvm filename: /lib/modules/3.11.4-101.fc18.x86_64/kernel/arch/x86/kvm/kvm.ko license: GPL author: Qumranet depends: intree: Y vermagic: 3.11.4-101.fc18.x86_64 SMP mod_unload parm: min_timer_period_us:uint parm: ignore_msrs:bool parm: tsc_tolerance_ppm:uint parm: allow_unsafe_assigned_interrupts:Enable device assignment on platforms without interrupt remapping support. (bool)
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.
# /usr/bin/qemu-kvm Could not access KVM kernel module: No such file or directory failed to initialize KVM: No such file or directory
looking at strace: open("/dev/kvm", O_RDWR|O_CLOEXEC) = -1 ENOENT (No such file or directory)
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?
