Update.
I think maybe we need to refactor 'power_cycle' function in TestSupport.pm. I 
have not try it, something like below?
sub power_cycle ($) {
    my ($ho) = @_;
+    if (guest_var($ho,"enable_nestedhvm",'') =~ m/true/) {
+        guest_destroy($ho);
+        guest_create($ho);
+        guest_await_dhcp_tcp($ho,300);
+        guest_check_up($ho);
+    } else {
        $mjobdb->host_check_allocated($ho);
        die "refusing to set power state for host $ho->{Name}".
            " possibly shared with other jobs\n"
            if $ho->{SharedMaybeOthers};
        power_state($ho, 0);
        power_cycle_sleep($ho);
        power_state($ho, 1);
+    }
}
