Hi,

I was trying to use clh as kata's hypervisor, however, the sandbox failed to start. After some rough debug, i noticed it failed at:

func (clh *cloudHypervisor) bootVM(ctx context.Context) error {

cl := clh.client()

if clh.config.Debug {
    bodyBuf, err := json.Marshal(clh.vmconfig)
    if err != nil {
        return err
    }
    clh.Logger().WithField("body", string(bodyBuf)).Debug("VM config")
}
_, err := cl.CreateVM(ctx, clh.vmconfig)
   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Failed point ^^^^^^^^^

the clh api server responded with: ID=fd26505c2b563c6ae8a2c351799cc510ba27b9e08067af945dc8b477a6689346 error="error: 400 reason: SerdeJsonDeserialize(Error(\"missing field sock\", line: 1, column: 845))" source=virtcontainers subsystem=cloudHypervisor

BTW, there is a BUG that no cleanup work if that error condition happened, that caused new vm was created infinitely and failed VMs were still staying on the system.

Could anyone figure out anything was wrong?
