Hi, I hope it is the right forum to post my query. I am currently looking at the possibility of adding a new VCPU to a running guest VM in KVM/ARM. I see that currently, it is not allowed to add a new VCPU to a guest VM, if it is already initialized. The first check in kvm_arch_vcpu_create() returns failure if it is already initialized. There was some work done in QEMU to add support for VCPU hotplug: https://lists.gnu.org/archive/html/qemu-arm/2017-05/msg00404.html But I am looking at the KVM side for enabling adding a new VCPU. If you can point me to any relevant work/resources, which I can refer to then it will help me. Thanks. Regards, Bhupinder |
