Yep, it is possible to run the tests inside VMs - the key is that when you create the VMs you need to be able to give them NUMA topology. This is possible if you're creating your VMs using virt-install, but not if you're creating your VMs in a cloud. > Note that in addition to setting up and maintaining the infrastructure, > we also need someone to write test cases.
