[ovirt-users] how to take a snapshot for hosted-engine?

hello everyone. I want to take a snapshot for hosted-engine. I am intend to do the job that might do critical damages on hosted-engine such as to seperate the database from the engine. before I do these job, it will be nice that I take a snapshot for the engine and then recover it when occuring severe problems. However, I tried to take a snapshot for hosted-engine in RHV-M portal and failed to take the snapshot. Is there any ways taking a snapshot for hosted-engine?
