Is it possible to run Loko in Qemu running in VirtualBox?

$ cat /sys/module/kvm_intel/parameters/nested
Y

I tried it, but it throws an error:

$ qemu-system-x86_64 -kernel ps2demo -serial stdio -m 1G -enable-kvm
qemu-system-x86_64: multiboot knows VBE. we don't
KVM: entry failed, hardware error 0x80000021

If you're running a guest on an Intel machine without unrestricted mode
support, the failure can be most likely due to the guest entering an invalid
state for Intel VT. For example, the guest maybe running in big real mode
which is not supported on less recent Intel processors.
