I'm trying to get the virtualization running : I have the following settings:Mainboard: gigabyte ud3 990fxCPU: fx-9590Kernel: 3.11.0-12-genericLinux Mint 17In the bios both svm as well as IOMMU are enabledThough these settings, I have no virtualization enabledcat /proc/cpuinfo | grep -E svm|vmxis emptyand kvm-ok command yields:Your CPU does not support KVM extensionsI checked the cpu specs, its a quite new cpu and it DOES support virtualization.Any idea what have I missed? 
Enable virtualization with gigabyte ud3 990fx
virtual machine;hardware;cpu
grep is incorrect usecat /proc/cpuinfo | grep -iE svm|vmxif return something is ok.If didn't return nothing,try another kernel maybe more recent.
