On a Jessie host I can see nested kvm is set ------------------- cat /sys/module/kvm_amd/parameters/nested 1 ------------------ On the virtual machines I can see 'svm' but not seeing /sys/module/kvm_amd . When I try to create a VM, I get Warning : KVM is not available. KVM kernel modules are not loaded. lsmod |grep kvm says its loaded. What did I miss? Thanks Paras.

[...] You need to expose the virtualization feature the VMs. For Intel machines, it works as described on my page at http://masysma.lima-city.de/37/how_to_transition_from_virtualbox_to_kvm.xhtml (Section ``Enabling Nested Virtualization...'') For AMD, I do not know how to do it, but if I understand it correctly, it cannot be too much of a difference. HTH Linux-Fan -- http://masysma.lima-city.de/

On the vm: The problem is: kvm module is loaded but not kvm_amd. When I do: modprobe kvm_amd I get modprobe: ERROR: could not insert 'kvm_amd': Invalid argument On the server: Looks like something is missing even though it says nested on "1".
