Short answer: don't do that.
It's the same reason why you normally should not use a single LUN in
SAN to boot multiple servers. Because it will lead to data corruption.

There are, however, scenarios when using shared storage is OK. One of
them is when you use cluster file system. In that case,  you can use
"w!" in disk mode on domU config file instead of the usual "w".
