Can RHEL7 VM run remote commands to Fedora36 host?

[Benjamin Smith]

Well I don't know if this helps, but it's there a reason you haven't tried
running the command that succeeds on the laptop directly over SSH?

EG:
ssh LAPTOPUSER at Laptop "virsh --connect qemu:///system start
beaker-test-vm1.beaker"
