An example script which send messages to vdsm none

Description Gal Hammer 2011-08-03 13:40:43 UTC 
Description of problem:

vdsm seems to read only one message at a time. This mean that if a lot of messages are been send in a small time period, vdsm handle only the first message. The next message is handled only after more messages are read.

How reproducible:

Use the attach script to send messages from the guest to vdsm. You'll see that the client ip is not updated.
