Introduction
KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). The following part of this tutorial will explain how to build and run ERIKA3 on top of the KVM hypervisor on the x86-64 platform.
Build ERIKA3 for KVM
Building ERIKA3 for Xen requires building an ERIKA3 image for bare-metal as described in the following tutorial: 'Building a bare-metal x86-64 image'.
With reference to the RT-Druid OIL configuration, set the the platform configuration parameters to generate the bare-metal image:
PLATFORM = BARE
As for the interrupt controller configuration, KVM supports the APIC or X2APIC with the NO_TSC_DEADLINE mode (note that the X2APIC in the TSC_DEADLINE mode is not currently supported on KVM hypervisor). That is the possible OIL configuration are:
INT_CONTROLLER = APIC
or
INT_CONTROLLER = X2APIC { X2APIC_MODE = NO_TSC_DEADLINE; }
Run ERIKA3 on KVM
The path of the generated ERIKA3 bare-metal image (e.g., erika3.iso) has to be used to run the KVM.
The command to run the ERIKA3 on KVM is the following:
kvm erika3.iso -cpu host -smp 1 -serial stdio -m 1G -no-reboot -no-shutdown
In order to pin ERIKA3 on a given CPU, use the Linux taskset command as follows;
taskset -c $CPUID kvm erika3.iso -cpu host -smp 1 -serial stdio -m 1G -no-reboot -no-shutdown
where $CPUID is the identifier of the chosen CPU.
