We can take snapshots easily but we have to pause the computation state to do so. We can backup the disc without pausing the system.
Is there any way that we can also snapshot the computation state of the guest without pausing the guest in QEMU/KVM?
As per my knowledge, the external snapshot does not preserve the computation e.g a program running at the moment won't be stored from exactly the same step it was on when it was snapshotted.
