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?

Hi, I remembered reading about Intel Clear Containers [1], and Hyper/Qboot [2] that support startup times measured in the hundreds of miliseconds range. On an AMD FX(tm)-8350 'guestfish -a /dev/null run' takes ~4s when run the 2nd/3rd time: real 0m4.152s user 0m2.120s sys 0m0.564s Are there any plans on applying these improvements to the supermin appliance? I did some quick tests on

Implement a virtio-iommu device and translate DMA traffic from vfio and virtio devices. Virtio needed some rework to support scatter-gather accesses to vring and buffers at page granularity. Patch 3 implements the actual virtio-iommu device. Adding --viommu on the command-line now inserts a virtual IOMMU in front of all virtio and vfio devices: $ lkvm run -k Image --console virtio -p
