Hello! > My current guest kernel is v3.19.5. I will test on 4.1rc2 soon.
Retested with 4.1.0rc2 (linux-stable.git master). Works perfectly fine with up to 8 CPUs. Here is boot log from 16 CPUs, listing potential problems: --- cut --- Initializing cgroup subsys memory Initializing cgroup subsys hugetlb hw perfevents: no hardware support available EFI services will not be available.
