make vm start only if another is shut down

Hi

i'm wondering if there is any way to set up a vm so that it cant start if another vm is offline?

exs:

vm1 has usb 1 and 2 connected and has some software that is dependent on usb1 to work

vm2 has some software that is dependent on usb 1

make vm2 not start untill vm1 is shut down

is this possible?
