Thanks for all the replies. Looking at the specs for the processor it does not seem to have the vmx features in /proc/cpuinfo: http://www.notebookcheck.net/Intel-Core-2-Duo-T6400-Notebook-Processor.35100.0.html and the output from grep -E ‘vmx|svm’ /proc/cpuinfo is empty. /lib/modules/3.10.0-229.7.2.el7.x86_64/kernel/arch/x86/kvm [keith.roberts at acer-centos kvm]$ ls kvm-amd.ko kvm-intel.ko kvm.ko [keith.roberts at acer-centos kvm]$ [keith.roberts at acer-centos kvm]$ modprobe kvm-intel modprobe: ERROR: could not insert 'kvm_intel': Operation not permitted [keith.roberts at acer-centos kvm]$ lsmod | sort ... iwlwifi 112501 1 iwldvm jbd2 102940 1 ext4 kvm 461126 0 libahci 32009 1 ahci [keith.roberts at acer-centos kvm]$ modprobe kvm-amd modprobe: ERROR: could not insert 'kvm_amd': Operation not permitted [keith.roberts at acer-centos kvm]$ modprobe kvm-intel modprobe: ERROR: could not insert 'kvm_intel': Operation not permitted Is it still possible to create some KVM type virtual machines with this laptop, to be ported to the VM host server machine later, or do I need another laptop with the required CPU flags?
