I confirm that this issue arises even with kernels 3.8.0-27 and 3.10 (tryied on Ubuntu): dmesg shows the message "kvm: disabled by bios" I don't know if Red Hat has the 'kvm-ok' executable, BTW in Ubuntu it says that the machine is capable of running KVM, but KVM is disable. This is the output: # kvm-ok INFO: /dev/kvm does not exist HINT: sudo modprobe kvm_amd INFO: Your CPU supports KVM extensions INFO: KVM (svm) is disabled by your BIOS HINT: Enter your BIOS setup and enable Virtualization Technology (VT), and then hard poweroff/poweron your system KVM acceleration can NOT be used On Fedora based systems, you can run $ virt-host-validate QEMU: Checking for hardware virtualization : PASS QEMU: Checking for device /dev/kvm : PASS QEMU: Checking for device /dev/vhost-net : PASS QEMU: Checking for device /dev/net/tun : PASS LXC: Checking for Linux >= 2.6.26 : PASS (NOTE: 'libvirt-client' package provide the above tool.) FYI: we've got pretty heavy email traffic regarding this issue, will update as soon as will confirm the problem. *********** MASS BUG UPDATE ************** We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 18 kernel bugs. Fedora 18 has now been rebased to 3.11.4-101.fc18. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you have moved on to Fedora 19, and are still experiencing this issue, please change the version to Fedora 19. If you experience different issues, please open a new bug report for those. *********** MASS BUG UPDATE ************** We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. It has been over a month since we asked you to test the 3.11 kernel updates and let us know if your issue has been resolved or is still a problem. When this happened, the bug was set to needinfo. Because the needinfo is still set, we assume either this is no longer a problem, or you cannot provide additional information to help us resolve the issue. As a result we are closing with insufficient data. If this is still a problem, we apologize, feel free to reopen the bug and provide more information so that we can work towards a resolution If you experience different issues, please open a new bug report for those.
