Hypervisor Support This release of the Red Hat OpenStack Platform is supported only with the libvirt driver (using KVM as the hypervisor on Compute nodes). This release of the Red Hat OpenStack Platform runs with Bare Metal Provisioning. Bare Metal Provisioning has been fully supported since the release of Red Hat OpenStack Platform 7 (Kilo). Bare Metal Provisioning allows you to provision bare-metal machines using common technologies (such as PXE and IPMI) to cover a wide range of hardware while supporting pluggable drivers to allow the addition of vendor-specific functionality. Red Hat does not provide support for other Compute virtualization drivers such as the deprecated VMware "direct-to-ESX" hypervisor or non-KVM libvirt hypervisors. 1.10.
