VirtualBox Nested Virtual Machine Containers with KVM Not Working no SVM or VMX module in the guest
I can't get vmx cpu extensions to show up in Virtualbox guests despite enabling nested paging and
enable vmx in virtualbox guest but this doesn't help that you check VT-X or the AMD Virtualization SVM it enables it for the guest to use BUT does not pass it through. This means if you check cat /proc/cpuinfo in the guest you will see the CPUdoesn't support virtualization. It looks like VirtualBox still hasn't implemented this!
But there is good news I&n........
kvm centos cannot compile error
