Hi Jean, I am trying to run and review on my side but I see Linux patches are not with latest kernel version. Will it be possible for you to share your Linux and kvmtool git repository reference?

This is a first go at adding support for the modern (based on the 1.0 virtio spec) virtio-pci implementation. kvmtool makes it simple to add additional transports such as this because of it's layering, so we are able to add it as a 3rd (after legacy virtio-pci and virtio-mmio) transport layer, and still allow users to choose to use either the legacy or the modern implementations (but setting

Hi, The following patches fix few bugs/APIs in configfs.
