Hello Julio,

we got two KVM kernels, Xenial and Bionic, I think you're targeting the latter.

In this case you will need to add [bionic/linux-kvm] to your title [1].
The title should be like [2]:
  [bionic/linux-kvm][PATCH] UBUNTU: [Config]: Enable ACPI NVDIMM

And your patches to change configs:
    1. [PATCH] UBUNTU: kvm: [Config] Enable ACPI NVDIMM
    2. [PATCH] UBUNTU: kvm: [Config] Enable IP set and netfilter
    3. [PATCH] UBUNTU: kvm: [Config] Enable memory hotplug

It looks like that they should be applied in a proper sequence, I can't apply
the third one first. You can submit these as a patch set to avoid this issue.
