RHEL KVM auto boot order?

I am trying to get 2 separate guests to boot one after another. One has databases the other needs to start. Is there a way to do this? Maybe adding a 10 second delay at startup or something like that.

Thanks

According to the last comment here https://access.redhat.com/discussions/685243 a time delay between guests is possible, although it doesn't say if you specify which guests.. probably not.
In any case, time delay is inherently risky.

I'd go with disabling the auto-start of the KVMs on boot up of the underlying host and instead add to eg /etc/rc.local (or equiv) some kind of test to use eg db connect to kvm1 before starting kvm2..
Alternately, maybe you can add something like that into kvm2 itself, so it doesn't start the dependent processes until the DB on kvm1 is already up.
The latter is better for eg restarts that don't involve the underlying host.

Thanks for the reply. The only issue with that is the databases are on a Windows box and the one that needs to start later is Ubuntu. We have a few apps made for them to talk nicely except for this one problem.

Along the lines of what Chris said, couldn't you create your own startup script using virsh to start each vm in your desired order, with your own tests between starting each vm, rather than relying on the autostart setting?

I don't have RHEL, but on CentOS 7 virt-manager allows you to specify the order that vm's start.

You could steal a test from Nagios most likely or write your own.
I've worked at a place where we installed the nagios tests so we could borrow a few for our own purposes.
