I am trying to experiment with the X86KvmCPU to see whether it will speed up my simulations through checkpointing but I'm having trouble (as I thought) getting it to work. First of all, I'm using VMWare to virtualise Linux on Ubuntu 16.04 LTS and in the Processor settings, I have enabled
Virtualize Intel VT-x/EPT or AMD-V/RVI Virtualize CPU performance counters I installed kvm and ran kvm-ok which reported back INFO: /dev/kvm exists KVM acceleration can be used Then when I try to run a simulation in SE mode using build/X86/gem5.fast configs/example/se.py -c tests/test-progs/hello/bin/x86/linux/hello --cpu-type=X86KvmCPU It generates information then ends in a backtrace with the panic error panic: KVM: Failed to enter virtualized mode (hw reason: 0x80000021) My problem is the same as https://www.mail-archive.com/[email protected]/msg10948.html Does anyone know what I should do? Thanks
