I set the default behaiour to SCMP_ACT_ALLOW and the exceptions to SCMP_ACT_KILL; remembering it inherits the behavior from the previous installed whitelist. This patch series also contain the command line support for this feature and some minor fixes, all of them described in their own commit messages. v1: The second whitelist is installed right before the vcpu starts, it contains all the system calls the first one has except for exec() and select(), which are big major syscalls that I could extensively test with virt-test and do not cause any damage to the general execution. The environment in which the second whitelist is installed seems to need less system calls than the first, so the procedure here will be the same: Keep testing with virt-test and get to the smallest list as possible.
