COLO FT/HA (COarse-grain LOck-stepping Virtual Machines for Non-stop Service)
|
|
project is a high availability solution. Both primary VM (PVM) and secondary VM
|
|
(SVM) run in parallel. They receive the same request from client, and generate
|
|
response in parallel too. If the response packets from PVM and SVM are
|
|
identical, they are released immediately. Otherwise, a VM checkpoint (on demand)
|
|
is conducted.

for details.
