Attempt to evaluate Cockpit Web Console on Server Fedora 33 (VENV) based on the most recent nightly build

UPDATE 10/08/2020 

UEFI option for KVM guests  on Manjaro Gnome 20.1.1 (Micah) might be enabled via  only after activation AUR 's support.


In current post we intend to test Cocpit Web Console functionality on pre-release Fedora 33 Server based on the most recent Fedora nightly builds list . Start with deploying Server Fedora 33 as VM (Level 1) on Server Fedora 32 (bare metal)

Install KVM and Cocpit Web Console on Server Fedora 33

$ sudo dnf groupinstall 'Virtualization'

Setup Web Cockpit Console of F33 Server (VM)
    $ sudo dnf install cockpit cockpit-machines

Service start up

$ sudo  systemctl start cockpit.socket
$ sudo systemctl status cockpit.socket
$ sudo systemctl enable cockpit.socket

Firewall tuning 

$ sudo firewall-cmd --add-service=cockpit --permanent
$ sudo firewall-cmd --reload
$ sudo reboot

Setup bridge bridge0 attached to virtual network interface of L1 VM Server F33 via Cockpit Web Console and proceed with deploying Manjaro Gnome L2 KVM guest attached to bridge0 . Notice that both L1 and L2 KVM Guests deployed into UEFI mode via option provided by Web Console . XML-profile of L1 F33 Server has been also modified via virsh to enable nested KVM. Per my experience deploying KVM guests via Web Console (UEFI mode) is possible only on Fedora 32/33 and SparkyLinux 2020.09 in meantime .

Now start installation VM and activate console's virt-viewer
As of 10/08/2020 same flag's setup during  install on /dev/sdb (bare metal) allows Calamaris complete without crash, after updating major grub.cfg
$ sudo grub2-mkconfig -o /etc/grub2-efi.cfg
I am getting installation Manjaro Gnome 20.1.1 (Mikah) on /dev/sdb which might boot up only via grub's entry

Update as of 10/11/2020

Section "Image creation and activation"
  1. the default ramdisk image created following the directives specified in the mkinitcpio #Configuration, and
  2. the fallback ramdisk image, same as above except that the autodetect hook is skipped during creation, thus including a full range of modules which supports most systems.

UEFI option for KVM guests  on Manjaro Gnome 20.1.1 (Micah) might be enabled via  only after activation AUR 's support.
Gparted report after booting up Manjaro Gnome 20.1.1 on bare metal. I intend to retry install with flags "boot","msfdata" for /boot/efi on bare metal at my earliest convenience ( added 10/10/2020 )  

Now return to mainline of blog post

On next snapshot show the output of Web Console which allows to setup und update L2 Mangaro KVM guest ( when guest is down )

Thus we succeeded with deploying L2 KVM Guest via Cockpit Web Console
