After updating compute nodes from OSP10/RHEL-7.4 with packages from 2018 to latest OSP10 and RHEL-7.7, instances created from glance images that have set the property os_distro=rhel7.5 fail to create, boot or migrate over updated compute nodes with the following error:

Instances created from glance images without the os_distro=rhel7.5 property work fine.

--- Additional comment from Mikel Olasagasti on 2019-10-11 08:04:24 UTC ---

Changing os_distro=rhel7.5 with to os_distro=rhel, os_version=7.5 seems to be a valid workaround.

Changing to OSP13 as it is also affecting OSP13.
