It is working fine in rhel 7.9, but the same thing giving ssh timeout error in RHEL 8.4.
But when i am creating guest vm with virt-install it is able to create a vm and i am able to see it in cockpit web ui, but when i initiate packer build with qemu plugin then giving ssh timeout error it is not visible in cockpit UI, so not able to see where the guest vm created get stuck.
Can anyone please help me to fix this issue where why vm not able to come up and also why qemu created vm not visible in cockpit web ui as that will be really helpful while debugging
