Hello there,

the newest grsec test patch is working fine on a physical machine, but with a kvm guest machine it stops booting at the first second without any related logs ..

OS: Ubuntu 16.04 LTS 64Bit
gcc: gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.4)

regards

we are already working on this problem which is caused by some missed instrumentation and type mismatches in the paravirt code that will need some surgery to fix properly. if you can live without PARAVIRT, disable it in the meantime.
