Hi all, I have a problem running the latest version of kvm with nested configuration. I used to run it with kernel 3.2.2 both for L0 and L1, which works perfectly. When I change my L0 to kernel 3.10.36, L1 to kernel 3.12.10. When I start L2 guest in L1 with qemu-kvm. I get the following error from the qemu-kvm.
Try upgrading L0 to a more recent kernel, 3.13 should be enough. Paolo
