install a device pluging for kubernetes

pushd sriov-network-device-plugin
# [optional] Running on a VM? - add a virtio net to the ConfigMap
# NOTE: The QEMU VM must have an extra virtio NIC device and support iommu:

Hot plugging devices using ACPI, SHPC and native

This gist is to show different ways to hot plug devices in a Virtual Machine

Set up the environment

Create a device mapper

dd if=/dev/zero of=devmap.img count=1 bs=50M

Create a functional Clear Container image using osbuilder

sudo -E FS_TYPE="ext4" USE_DOCKER=1 DISTRO=clearlinux AGENT_INIT=no EXTRA_PKGS="dbus-bin dbus-autostart util-linux-bin p11-kit-bin bash shadow ca-certs dist-pam-configs xz-bin tar-bin grep-bin sed-bin pigz-bin iproute2-bin procps-ng-bin psstop-bin htop-bin curl nano make-bin coreutils-bin pciutils strace-bin e2fsprogs-extras" make -e rootfs
sudo -E FS_TYPE="ext4" USE_DOCKER=1 DISTRO=clearlinux make -e image
