In newer versions of QEMU, like 4.0-rc2, QMP events can be thrown even before the QMP-version response, one example of this behaviour is when a virtio serial is closed and a VSERPORT_CHANGE event is thrown. Re-implement mainLoop to check the data received from the VM channel, since it's not a guarantee that the first data read from the VM channel is the QMP version. fixes https://github.com/kata-containers/runtime/issues/1474 Signed-off-by: Julio Montes <julio.montes@intel.com>
Virtual Machine Manager for Go
Virtual Machine Manager for Go (govmm) is a suite of packages that provide Go APIs for creating and managing virtual machines. There's currently support for only one hypervisor, qemu/kvm, support for which is provided by the github.com/intel/govmm/qemu package.
The qemu package provides APIs for launching qemu instances and for managing those instances via QMP, once launched. VM instances can be stopped, have devices attached to them and monitored for events via the qemu APIs.
The qemu package has no external dependencies apart from the Go standard library and so is nice and easy to vendor inside other projects.
