Yeah, but I think if we have to take advantage of live vertical scaling (memory hotplug, memory hotunplug, cpu hotplug) then we need to upgrade to pc model 1.2. pc model 1.0 will be incompatible with qemu 2.0 wrt. LVS feature as the bus architecture and the way how dimms are handled has changed fr

Hi, In our data center we are using qemu 1.0/ 1.2 and we need to do a live migration to qemu 2.0. One of the main hindrance that we are facing is that QEMU 1.0 uses old PC model so if a user using Windows on the VM running on QEMU 1.0 does a live migrate to QEMU 2.0 , he will see a licensing issu
