Pings and other networkconnections time out after live migration
Depending on the setup of the virtual machines and client settings it might happen that the connection times out. Read here on more information. THIS FAQ ENTRY IS NOT EXACTLY THE OPTIMAL WAY AND NEEDS TO BE REWORKED BUT IT CAN BE USED AS PROOF-OF-CONCEPT

Background
Depending on the setup of the virtual machines and client settings it might happen that the connection times out. This seems to come from the arp-cache of the guest machine. If it is cleared after every live migration "no" or nearly "no" network packets should get lost or time out.
Workaround as POC
Run the referenced skript as proof-of-concept to see if you are affected on this problem. This skript should be move to the background.
Koncept of a productive workaround
The clearing of the arptable should only happen when live migration took part. But HOW should this be done is the question??
