Hi Salil,
I've shared the test results of k8s + kata containers in LKML of Russell's v3 patch set. Hope it helps.
Thanks Jianyong

Hi Jianyong, Many thanks for taking pains and sharing the results of your testing in this forum and which look quite promising. I would encourage you to share the same to the wider audiences in the mailing-list in reply to some Linux kernel patches.
As per the latest update Greg-Kroah-Hartman has agreed to pull some of the Russell's patches related to VCPU cleanups which is great.
https://lore.kernel.org/lkml/2023120131-leotard-deprecate-4e27@gregkh/
These results will increase confidence on the remaining patches although the key issue of the ACPI still remains unresolved and Russell has already asked that question again from Rafael yesterday

Thanks Salil

Hi Salil,
Overall, I have done the k8s test. The full test log locates http://jenkins.katacontainers.io/job/kata-containers-tests-experimenta l- ARM-ubuntu/18/console The log is so large. You need scroll down to the bottom of it to find the log like:
[Log begin:] 17:18:13 1..1 17:18:18 ok 1 Check CPU constraints 17:18:18 1..1 17:20:21 1..1 17:20:36 ok 1 Check number of cpus 17:20:36 1..1 [log end]
These 2 are the k8s test result related with vCPU Hotplug. You can see that both are PASSED. You can refer to https://github.com/kata- containers/tests/blob/main/integration/kubernetes/k8s-cpu-ns.bats and https://github.com/kata- containers/tests/blob/main/integration/kubernetes/k8s-number-cpus.bats to find the detail of the test.
kernel branch in this test: git://git.armlinux.org.uk/~rmk/linux-arm.git branch: origin/aarch64/hotplug-vcpu/v6.6-rc7 and VMM use Salil's v2 patch.
Thanks Jianyong

Hi Jianyong, A request, is it possible to share the results of the testing through mailing list for the wider audience?
