Doc Type: Enhancement
Doc Text:
This enhancement changes the default machine type for each host architecture to Q35 (`pc-q35-rhel9.0.0`) for new Red Hat OpenStack Platform 17.0 deployments. The Q35 machine type provides several benefits and improvements, including live migration of instances between different RHEL 9.x minor releases, and the native PCIe hotplug that is faster than the ACPI hotplug used by the `i440fx` machine type.

Description Lee Yarwood 2021-04-07 11:14:27 UTC 
Description of problem:

This bug is specifically to track the change to the default value of the NovaHWMachineType parameter to make `q35` the new default in fresh deployments.

As set out in bug #1946944 this will be pinned to a versioned q35 machine type to allow migrations back and fourth between minor RHEL versions (x.y -> x.y+1 and x.y+1 -> x.y).
