Problem with viewing VNC from KVM using virt-install

I have used the command to create the wild VM over KVM:
My base OS is Rocky Linux 9.

virt-install --name Parrot --ram 2048 --vcpus 1 --disk path=/var/lib/libvirt
/images/parrot.img,size=20 --os-variant debian11 --network bridge=br0,model=virtio --graphics vnc,l
isten= --console pty,target_type=serial --cdrom /tmp/Parrot-security-5.0.1_amd64.iso --conne
ct qemu:///system

After importing the wild VM into openNebula Vm’s, I tried to start it.
I am getting this message:

How can I resolve it? Plz help…

Are you able to access the VNC port using an external VNC viewer?
