Hi Laszlo, Thank you for your quick response, and apologies for the your pervious mail thread which i could not observed as I only monitor the mail [ pavankumar_a@accelerite.com ]inbox. And I am not receiving mail reply's to my inbox even though i have subscribed to devel group. Here after i will proceed with web console https://edk2.groups.io ( https://edk2.groups.io/ ) for tracking info. as you suggested, I have done the dom xml changes you suggested in previous mail that * Dom XML Changes for OVMF loader stuff * deleted existing  varstore file /var/lib/libvirt/qemu/nvram/ I am unable to boot the VM saying that there is no bootable device to boot , attached the screen shot with this thread for the same. I have been using  image https://www.kraxel.org/repos/images/fedora-28-efi-systemd-x86_64.qcow2.xz for Guest VM Boot. Please suggest me if i missed out some thing. Regards, Pavan.
