Enabling UEFI Support For KVM Virtual Machines on Manjaro Deepin Edition (“Mikah,” Manjaro 20.1)

 This is an immediate followup for post at Lxer.com   http://lxer.com/module/newswire/view/291652/index.html

Tested on Virtual Box VM (Manjaro Deepin) , i.e. VENV testing . Manjaro Deepin VM (L1) was launched via Virtual Box with nested virtualization enabled .  

Seems to be fixed via $ sudo pacman -S edk2-ovmf

Virtual Box VM CentOS 8.2 started in UEFI mode

Setting up Fedora 33 beta L1&&L2 KVM guests all seating on the same office LAN

Following below verifies Fedora 33 beta L1 Guest ability to perform KVM deployment Fedora 33 beta L2 Guest inside itself .

Deployment is based on bridge to virtual interface of L1 F33 beta guest ( rather then NAT ) due to L1 guest has been deployed on external office network , L2 Guest also appears to be set up on the same external network. Server Fedora 32  (bare metal) has been placed on office LAN via Cockpit Web Console. On L1 Fedora 33 beta Guest we have manually set up bridge br01 via nmcli CLI. 

Creatining bridge br01 on F33 Beta L1 KVM Guest
$ nmcli connection add ifname br01 type bridge con-name br01
$ nmcli connection add type bridge-slave ifname  enp1s0 master br01

$ sudo nmcli con modify br01 bridge.stp no

$ sudo reboot

Bridge br01 to virtual network interface has been created.

Now deploying F33 Beta L2 Guest via shared device br01

F33 Beta L2 Guest has been deployed

Surfing the Net from F33 Beta L2 Guest . Taskbar at the bottom of snapshot belongs to Server Fedora 32 (bare metal) with Deepin desktop as administrative console

Setting up Sqlite3 Python embedded database and Sqlitebrowser on Virtual Box CentOS 8.2 VM

 Proceed with normal VM's install via CentOS-8.2.2004-x86_64-minimal.iso in Virtual Box 6.1.X. Notice that same straight forward install from scratch of Sqlite3 database would work on bare metal as well . Just no VBoxLinuxAdditions.run related commands.

 When done :-

   $ uname -a

  $ sudo dnf update -y

   $ sudo reboot

   $ sudo dnf install sqlite-devel qt5-* -y

   $ rpm -q sqlite-devel

   $ sudo dnf install wget

   $ sudo dnf groupinstall "Development Tools" -y

   $ tar xvf Python-3.8.5.tgz

Install Ubuntu 20.04.1 as Virtual Box Guest on Fedora 32 Server

First follow https://computingforgeeks.com/how-to-install-vagrant-and-virtualbox-on-fedora/  Per standard procedure deploy Ubuntu Virtual Box Guest via local ISO image. Right after logging into newly created instance run :-

$ sudo apt install build-essential dkms linux-headers-$(uname -r)

Then Goto Menu option "Devices" and select from drop down list "Insert Guest =>Additions CD Image" . Perform actions requested by raised up window. Shutdown Ubuntu instance and start again to be able scale guest window as advised in video

$ sudo dnf update -y ;  $ sudo shutdown -P now

Attach to F32 VM VBoxGuestAdditions_6.1.14.iso. Start up VM

Shutdown F32 Guest and start again

Install CentOS 8.2 KVM Guest on SparkyLinux2020.09 via Web Cockpit Console

First notice that we are installing on Ryzen box with board MSI X570 A-PRO in UEFI mode with "kvm" enabled.
First of all we intend to verify that kvm has been enabled 
   $ dmesg | grep kvm
   [ 4.376968] kvm: Nested Virtualization enabled
   [ 4.376978] SVM: kvm: Nested Paging enabled
and proceed with installing Virtualization Host the same way we
would do it on Debian “bullseye”

 $ sudo apt install qemu-kvm  libvirt-daemon bridge-utils \
         virtinst libvirt-daemon-system -y
 $ sudo apt install virt-top libguestfs-tools libosinfo-bin \
       qemu-system virt-manager -y
 $  sudo modprobe vhost_net 
 $  lsmod | grep vhost
 $  echo vhost_net | sudo tee -a /etc/modules
 $  sudo reboot

  It's nice to have virt-manager installed ( Spice console ) but presence of Web Cockpit Console is quite enough to manage guest's deployment via clicking  button "Remote Virt-viewer"  built into Cockpit Web Console. Bridge attached to external network interface was also created pretty  smoothly utilizing network management section inside Web Console.

Install Web Cockpit Console  
 $  sudo apt install cockpit cockpit-machines
 $  sudo systemctl start cockpit.socket
 $  sudo systemctl enable cockpit.socket

 Tuning firewall
 $  sudo apt install firewalld
 $  sudo firewall-cmd --add-service=cockpit --permanent
 $  sudo firewall-cmd --reload

Logging into Console at port 9090 and proceed as follows

Setting up Sqlite3 Python embedded database and Sqlitebrowser on CentOS 8.2

**************************************************************

UPDATE 09/25/2020

The most recent updates to CentOS 8.2 Repos makes qt5-devel unavailable,  so setup Qt5 has been updated correspondingly

Please, don't be hesitant to use "--skip broken" it might be required in case if you installed from complete DVD version (USB stick) and keep system in up to date shape. When install has been done from minimal DVD install qt5-* and afterwards $ dnf group install "Server with GUI" . See also Setting up Sqlite3 Python embedded database and Sqlitebrowser on Virtual Box CentOS 8.2 VM

**************************************************************

First instatll "Development Tools", rebuild Python 3.8.5
after installation sqlite-devel. Afterwards build sqlitebrowser from source rather then install via snap, qt5-* packages would have to be installed for successful build on CentOS 8.2.

$ sudo dnf groupinstall "Development Tools" -y
$ sudo dnf install sqlite-devel

Rebuild Python

$cd ; $ cd ./Python-3.8.5
$ ./configure —enable-optimizations
$ sudo make altinstall

Prepare to build sqlitebrowser which wouldn't
have any issues with Qt vs the one provided via snap

$ sudo dnf install qt5-* or $ sudo dnf install qt5-* --skip-broken

$ git clone https://github.com/sqlitebrowser/sqlitebrowser

$ cd sqlitebrowser
$ cmake -Wno-dev .
$ make
$ sudo make install
