Hi Ayaz, Thanks for the info. I’ve followed the steps there to setup kvm but the error is still present:
build/X86/sim/simulate.cc:194: info: Entering event queue @ 0. Starting simulation... build/X86/cpu/kvm/perfevent.cc:183: panic: PerfKvmCounter::attach failed (2) Memory Usage: 2390716 KBytes build/X86/cpu/kvm/perfevent.cc:183: panic: PerfKvmCounter::attach failed (11) Memory Usage: 2390716 KBytes Program aborted at tick 0 Maybe this might be a problem inherent to the VMs, even though I’m sure that the VM supports second level virtualization and KVM.
