Cloud-Hypervisor is a KVM virtualization using hypervisor. It functions similarly to qemu and the libvirt Cloud-Hypervisor driver uses a very similar structure to the libvirt driver. The biggest difference from the libvirt perspective is that the "monitor" socket is seperated into two sockets one that commands are issued to and one that events are notified from. The current implementation only uses the command socket (running over a REST API with json encoded data) with future changes to add support for the event socket (to better handle shutdowns from inside the VM). This patch adds support for the following initial VM actions using the Cloud-Hypervsior API: * vm.create * vm.delete * vm.boot * vm.shutdown * vm.reboot * vm.pause * vm.resume To use the Cloud-Hypervisor driver, the v15.0 release of Cloud-Hypervisor is required to be installed. Some additional notes: * The curl handle is persistent but not useful to detect ch process shutdown/crash (a future patch will address this shortcoming) * On a 64-bit host Cloud-Hypervisor needs to support PVH and so can emulate 32-bit mode but it isn't fully tested (a 64-bit kernel and 32-bit userspace is fine, a 32-bit kernel isn't validated) Reviewed-by: Daniel P.
