1 When we connect libvirt with URI "qemu+ssh", it uses 'nc' command to connect
to libvirt-sock.
# virsh -c qemu+ssh://root@9.61.1.74/system list

It in fact uses 'ssh' and 'nc' commands to connect to remote libvirt-sock, such
as:
ssh -l root 9.61.1.74 sh -c ''nc' -U /var/run/libvirt/libvirt-sock'
The code path is :
virConnectOpen->doRemoteOpen->virNetClientNewSSH->virNetSocketNewConnectSSH
2 However, netcat(nc) is considered as an insecure tool, because it's too
powerful in controlling the network.
It's abandoned by some organizations.
3 So, is there any good substitution for netcat to realize qemu+ssh?
