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

Subject: [kata-dev] hot plug/unplug for cloud hypervisor support

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

Wilson
