  UEFI VMs on KVM throwing error "No enum constant com.cloud.hypervisor.kvm.resource.LibvirtVMDef.WatchDogDef.WatchDogModel.ITCO"

Due to this the VMs are running but unable to open console or manage instance i.e start/stop instances

COMPONENT NAME

UI 

CLOUDSTACK VERSION

4.19.0.1

CONFIGURATION

OS / ENVIRONMENT

Used to ISO to boot VM , happens with all instance

SUMMARY

Cloudstack is managing and running VMs with BIOS boot perfectly , but when selected UEFI with Legacy or Secure below error is throw :

WARN [cloud.agent.Agent] (agentRequest-Handler-1:null) (logid:fb71c7dd) Caught:

I have checked out #8282 but that does not help much here as even with ITCO watchdog issue is coming up, i can see two watchdogs are being added on VM - 'i6300esb' and 'itco'

STEPS TO REPRODUCE

1. Create VM in KVM zone with UEFI option.
2. Try to take console

UEFI properties as below : 

cat /etc/cloudstack/agent/uefi.properties

guest.nvram.template.secure=/usr/share/edk2/ovmf/OVMF_VARS.secboot.fd
guest.nvram.template.legacy=/usr/share/edk2/ovmf/OVMF_VARS.fd
guest.loader.secure=/usr/share/edk2/ovmf/OVMF_CODE.secboot.fd
guest.nvram.path=/var/lib/libvirt/qemu/nvram/
guest.loader.legacy=/usr/share/edk2/ovmf/OVMF_CODE.secboot.fd
