Bo,

Thanks for your reply. 

My colleagues and I are working on some POC and it is based on Kata & K8s. The new features you mentioned will definitely help us. However, we are still at the very early stage and trying to prove that cloud hypervisor is truly what we are looking for compared to firecracker which does not have these features yet.

Regards

Wilson

Hi Wilson,

 

Thanks for promoting this question. Yes, that is our plan. Along with the supported device hot-plug we have in Kata with cloud-hypervisor (e.g. vcpu/memory/vfio), we are enabling block (‘disk ‘and ‘pmem’) device hot-plug very soon. For few other HTTP APIs related to device hotplug that cloud-hypervisor recently added (e.g. ‘/vm.add-fs’, ‘/vm.add-net’, and ‘/vm.add-vsock’), we will need to look into them and add support if there are use cases in Kata.

 

Carlos, would you please comment on the device hot-unplug side? Base on my limited understanding, we don’t have much use-case for device hot-unplug in Kata, right? Also, please correct me and add more for the device hot-plug side. Thanks a lot.

 

I hope it helps and makes sense to you. Any more questions or comments, please don’t hesitate to share.

 

Best,

Bo

Hi guys,

 

I have a question regarding Kata Containers hotplug support for cloud hypervisor.

 

I saw recently cloud hypervisor added support for several different virtio devices hotplug. But the support for this is not yet there in Kata Containers.

 

Do we have a plan to add this support soon?

 

Thanks
