Subject: VCPU hotplug on KVM/ARM

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
