If you have an 8GB vm you can see it in action via https://docs.openstack.org/devstack/zed/guides/single-vm.htm... (takes about 45 minutes) or if you want the "full" experience fire up an education cluster from https://openmetal.io/use-cases/on-demand-openstack-cloud/ (it takes about 4 hours or so but it's also a "real" setup unlike the vm which for sure allows running instances via qemu but isn't going to allow exercising the complete suite as easily)
