Comment 5 for bug 2018172

I try to downgrade the release of rdo openstack to xena with rhel8.7 because xena / yoga /zed dont work with rhel9. So, freshly install rhel8 and xena now get this error:

warning: 'cirrus-vga' is deprecated, please use a different VGA card instead

I dont know why but every freshly deployment of RDO dont work anymore, the docs are not updated from 2020 so its imposible to know what version its needed to install for get openstack work like in past (im installing and testing from queens). So, the 3/4 latest releases are very unstables and not usable at all using centos-stream / rhel based S.o and packages.

UPDATE:
Changes to be made in XENA / rhel8.7 for work:

/usr/lib/python3.6/site-packages/nova/virt/libvirt/config.py
CHANGE FROM
   2054 def __init__(self, **kwargs):
   2055 super(LibvirtConfigGuestVideo, self).__init__(root_name="video",
   2056 **kwargs)
   2057
   2058 self.type = 'cirrus'

TO
   2054 def __init__(self, **kwargs):
   2055 super(LibvirtConfigGuestVideo, self).__init__(root_name="video",
   2056 **kwargs)
   2057
   2058 self.type = 'virtio'

with this changes nova is working now in rhel8.7
