[Users] Host Error

Hi guys, We had a power failure over the weekend, and when powering everything back on, one of the hosts gives the following error when trying to re-activate it. "Host ovirt02.blabla.co.za running without virtualization hardware acceleration" I've checked in the machine's bios and the VT options are still enabled, I've reset the PC's bios and then confirmed all the CPU features were enabled as a precaution and yet I still get the same error. Could this be an ovirt/vdsm issue or is it more likely a hardware issue? These are my versions... vdsm-cli-4.10.3-10.el6.centos.alt.noarch vdsm-4.10.3-10.el6.centos.alt.x86_64 vdsm-xmlrpc-4.10.3-10.el6.centos.alt.noarch vdsm-hook-nestedvt-4.10.3-10.el6.centos.alt.noarch vdsm-python-4.10.3-10.el6.centos.alt.x86_64 ovirt-engine-genericapi-3.2.1-1.41.el6.noarch ovirt-engine-dbscripts-3.2.1-1.41.el6.noarch ovirt-engine-tools-3.2.1-1.41.el6.noarch ovirt-engine-sdk-3.2.0.9-1.el6.noarch ovirt-engine-restapi-3.2.1-1.41.el6.noarch ovirt-host-deploy-1.1.0-0.0.master.el6.noarch ovirt-log-collector-3.2.0-1.el6.noarch ovirt-engine-backend-3.2.1-1.41.el6.noarch ovirt-image-uploader-3.2.0-1.el6.noarch ovirt-engine-userportal-3.2.1-1.41.el6.noarch ovirt-engine-jbossas711-1-0.x86_64 ovirt-engine-setup-3.2.1-1.41.el6.noarch ovirt-host-deploy-java-1.1.0-0.0.master.el6.noarch ovirt-iso-uploader-3.2.0-1.el6.noarch ovirt-engine-3.2.1-1.41.el6.noarch ovirt-engine-cli-3.2.0.10-1.el6.noarch ovirt-engine-webadmin-portal-3.2.1-1.41.el6.noarch Any help is appreciated.
