it turned out that this is not what I should want to say. What I should say instead is: "Run all VMs on all cores, but if certain VMs suddenly spike, give them all they ask for at the expense of everyone else, and also avoid moving them around between cores, if possible." The idea is that these high priority VMs are (probably) idle most of the time, but at other times need high performance. It was thus deemed to be a huge waste to reserve cores for them. > https://review.openstack.org/#/c/555081/ Thank you for the pointer!
