Created attachment 432790 [details] Kerneloops automatically generated Description of problem: I have installed three virtual machines, two RHEL 5.5 and one RHEL 6 Beta 2. On top of RHEL 6 Beta 2. The machines constantly pause. Version-Release number of selected component (if applicable): RHEL 6 Beta 2 (from the ISO) How reproducible: Start machines, they pause after a while. Steps to Reproduce: 1. Install RHEL 6 Beta 2 2. Install and start a number of qemu-kvm guests 3. Wait and they will pause. Actual results: Machine constantly pause and the following is seen in dmesg on the base host doing the virtualization: EPT: Misconfiguration.
