The ContextID of VSOCK should be a uint64 not a uint32. That provokes an endianess issue in the kata-runtime. See kata-containers/runtime#947. Qemu requests an uint64:

$ qemu-system-x86_64 -device vhost-vsock-pci,help
[...]
vhost-vsock-pci.guest-cid=uint64

qemu: change of ContextID from uint32 to uint64
226228c 
The correct type used by qemu and in kernel is uint64 and this leads to
an endianess problem with ioctl system call. See the issue
kata-containers/runtime#947

Fixes: kata-containers#70
