Description Uri Lublin 2021-04-07 09:52:45 UTC

Description of problem:
SPICE has been deprecated in RHEL-8.3 and is to be removed from RHEL-9.

Please:
- Disable support for SPICE components (graphics, smart-card, USB, etc)
- Remove SPICE components from the default configuration (if one exists)

Comment 1 Uri Lublin 2021-04-07 09:55:13 UTC

I built (rhel-9.0 code on a Fedora 33) qemu-kvm without SPICE and without QXL,
and tested “virsh define f33.xml” (with SPICE or QXL) and it fails with errors.
"error: unsupported configuration: spice graphics are not supported with this QEMU"

So possibly it's enough to change the default configuration (if exists) such that it
does not fail for users.

$ rpm -q qemu-kvm libvirt-daemon libvirt-client
qemu-kvm-5.2.0-7.el9.0.1.uri3.x86_64
libvirt-daemon-6.6.0-5.fc33.x86_64
libvirt-client-6.6.0-5.fc33.x86_64

Comment 2 Peter Krempa 2021-04-07 10:37:08 UTC

Does your 'f33.xml' define use of spice explicitly?

According to the parser code the 'type' attribute to '<graphics' is mandatory, so you have to pick an explicit type, in such case the error message reported is correct since it's an explicit configuration and libvirt does not pick any default for you so there isn't anything to change.

(In reply to Peter Krempa from comment #2)
> Does your 'f33.xml' define use of spice explicitly?

Yes

    <graphics type="spice" port="-1" tlsPort="-1" autoport="yes">
      <image compression="off"/>
    </graphics>

Comment 4 Peter Krempa 2021-04-07 10:47:09 UTC

We can't simply do something which the user didn't request in this case. As noted libvirt doesn't pick a default graphics type and forces the user to specify it. We can't do anything here.
