OL7 vs. KVM: this QEMU doesn not support 'virtio' video device

Hi,

I just installed Oracle Linux 7 on my local sandbox machine. I'm testing its abilities to act as a KVM host/hypervisor.

Configuring a bridge and installing virtualized server systems works perfectly so far. I tried to install an OpenSUSE Leap 15.2 VM. To get a better resolution, I wanted to use the 'virtio' video device. But when I tried to fire up the VM, I got the following error message:

This QEMU does not support 'virtio' video device.

Now this is not a big deal, since I'm planning to host mainly server systems without a GUI under OL7. For the time being, I'm running graphical VMs on my OpenSUSE Leap workstation. But still, it would be a nice feature to have.

Any suggestions ?

    Can you try the version we provide in the ol7_kvm_utils repo? It's a lot newer than the one we get from upstream. Though, I'll be honest and say I'm not sure we prioritise video for exactly the reason you suggest: most of the VMs our customers run are headless instances.

    So I gave this a spin. I enabled the ol7-kvm repository and updated all KVM-related tools.

    And I still get a similar error:

    Unsupported configuration: spice graphics are not supported with this QEMU
    

    So this seems to confirm the fact that KVM on RHEL, CentOS and Oracle Linux mainly support headless VM configuration - or, more precisely, just enough graphics to display the installer.

    Cheers,
