Confirmed.  Cut+paste large text blocks in the guest -> hangs qemu
vdagent implementation, because the message doesn't fit into the
fixed-site (VD_AGENT_MAX_DATA_SIZE) message buffer.

So I need so switch to dynamic allocation when reworking the code for
proper size checks.

The other way around hangs too, seems the guest agent is not prepared
to receive large messages and expects them in chunks ...

take care,
  Gerd
