Description Mikel Olasagasti 2019-10-10 10:00:14 UTC

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:

File "/usr/lib/python2.7/site-packages/nova/virt/libvirt/blockinfo.py", line 241, in get_disk_bus_for_device_type

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

Comment 1 Mikel Olasagasti 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.

Comment 7 Artom Lifshitz 2020-03-23 12:33:38 UTC

I'm afraid I didn't get a chance to update the doc text before release (it went to RELEASE_PENDING in a matter of hours after the doctext needinfo), is there still a point in setting the doctext?
