i found this issue: https://bugs.launchpad.net/nova/+bug/1999803 that recommend to install this dependencies:

qemu-kvm-ui-opengl
qemu-kvm-device-display-virtio-gpu
qemu-kvm-device-display-virtio-gpu-gl
qemu-kvm-device-display-virtio-gpu-pci
qemu-kvm-device-display-virtio-gpu-pci-gl
qemu-kvm-device-display-virtio-vga
qemu-kvm-device-display-virtio-vga-gl
qemu-kvm-device-usb-host
qemu-kvm-device-usb-redirect

But after install i cant deploy new instances and the error still.

Thanks

https://libvirt.org/formatdomain.html#video-devices

as noted in the libvirt docs virtio was added in libvirt 1.3.0

The model element has a mandatory type attribute which takes the value "vga", "cirrus", "vmvga", "xen", "vbox", "qxl" ( since 0.8.6 ), "virtio" ( since 1.3.0 ), "gop" ( since 3.2.0 ), "bochs" ( since 5.6.0 ), "ramfb" ( since 5.9.0 ), or "none" ( since 4.6.0 ), depending on the hypervisor features available.

this has been supported for years we merely made it our default in nova.

OSP (redhats downstream distribution fo OpenStack) is not supported on rhel 9.1 in any capacity.

there is also no released package of Yoga / Zed as part of osp.

the most recent OSP release is based on wallaby based on rhel 9.0 and the upcoming 17.1
release will be wallaby on rhel 9.2

did you mean RDO? not OSP?

[Mathias Gonzalez (mathgonzlez)]

sorry, as you say im trying to install RDO in rhel 9.1 with packages installation, because osp (redhat) is based on tripleo.

[Mathias Gonzalez (mathgonzlez)]

hi,

have some update about this issue?

[Mathias Gonzalez (mathgonzlez)]

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
