Install KVM with UEFI Guests support on Manjaro KDE 20.1.1

UPDATE 21/10/2020

 Manjaro Gnome && KDE 20.1.2 are affected by the same bug

END UPDATE

Attempt to test another Linux distro Manjaro KDE 20.1.1 as Virthost managed via Cockpit Web Console, i.e. deployment and management KVM guests on the recent Manjaro KDE utilizing Web Console . Bare metal platform is Ryzen 7 3700X based with 16 GB RAM and mother board MSI X570 A-PRO ( SVM status enabled )

First thing to do is manual fix grub.cfg to avoid using only "fallback initramfs" grub entry as follows bellow

Then manually update grub.cfg :-

Another command is to install package supporting KVM guests UEFI deployment $ sudo pacman -S edk2-ovmf . In particular case bare metal  installation on gparted segment of drive /dev/sdb  had been performed with no issues both /boot/efi and /boot had been marked by flag "boot" and nothing else , obviously followed by 

$ sudo grub2-mkconfig -o /etc/grub2-efi.cfg

on Fedora Server 32 SSD drive , updating major grub.cfg on multiple systems booting up host . Updates mentioned above should be done manually to major grub.cfg on Fedora's SSD drive .

Now proceed the same way as for version 20.0.3
