But when you transfer a running machine to another cluster member there
is a transfer of the current machine state too!
So technically it should be possible to save ram content and cpu/machine
state...

If you're referring to Snapshot support in QEMU [1][2], when relying on
QCOW2 storage format, it seems that it isn't directly supported by
ProxMox.
As for ProxMox, it seems that the "Snapshot" support is always related
to
the underlying LVM kernel support. As such, it cover "only" storage
issues.

At least, this is what I understood from a thread discussed last month
on
this very same list [3].

Bye,
DV
