Hi Nux! That's why I said real "suspension" might rely on "virtual machine snapshot with memory capturing". see this discussion: http://markmail.org/message/apchw5rsf4xgevt4?q=list:org%2Eapache%2Eincubator%2Ecloudstack-%2A+suspend
Probably the real question is whether kvm could/will support "vm snapshot"?
