Install PVE in Metal Partition not Whole Disk

by

Learnt from referred link, we first install Xubuntu along with Win11 in the same metal disk,

then we reboot into Xubuntu, update it to PVE kernel,

# sudo vi /etc/apt/sources.list.d/pve-install-repo.list
	deb [arch=amd64] http://download.proxmox.com/debian/pve bullseye pve-no-subscription
 
sudo wget https://enterprise.proxmox.com/debian/proxmox-release-bullseye.gpg -O /etc/apt/trusted.gpg.d/proxmox-release-bullseye.gpg
 
sudo apt update
sudo apt full-upgrade
 
sudo apt install pve-kernel-5.15
 
reboot
 
sudo apt install proxmox-ve postfix open-iscsi

To be continued ...

p.s. dependency failed while installing pve in ubuntu, which means we must play it under debian os.

Install bare metal Linux dual booting with Windows

Installing Fedora is very straight forward, but

  • When clicking some avi suffix video file, I was prompted a GStreamer page, but no link to install missing plugins.

However I learnt

  • One disk must have its own EFI partition. For nowaday notebook usually has an SSD and an HDD, while SSD already has an EFI partition, when we have to install the second OS in HDD, the HDD must allocate an EFI partition too.
  • When we burn OS iso image into U-disk using UltraIso tool, we must select "RAW" mode, not others like "HDD+" mode.

'vboxdrv': Key was rejected by service

sudo dnf update
sudo dnf install mokutil

mkdir /root/signed-modules
cd /root/signed-modules
openssl req -new -x509 -newkey rsa:2048 -keyout MOK.priv -outform DER -out MOK.der -nodes -days 36500 -subj "/CN=VirtualBox/"
chmod 600 MOK.priv

mokutil --import MOK.der

#After rebooting system

for modfile in $(dirname $(modinfo -n vboxdrv))/*.ko; do
  echo "Signing $modfile"
  /usr/src/kernels/$(uname -r)/scripts/sign-file sha256 \
                                /root/signed-modules/MOK.priv \
                                /root/signed-modules/MOK.der "$modfile"
done

To play avi, rmvb files and so on, 

dnf install https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm
dnf install https://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm
dnf install vlc

Not set default editor to nano in cscope, 

cd /etc/profile.d
mv nano-default-editor.sh nano-default-editor.sh0

No sound? 

vi /etc/pulse/default.pa
	load-module module-alsa-sink device=dmix
	load-module module-alsa-source device=dsnoop
reboot

This method doesn't go very well, but I know the reason, I had replaced pipewire with pulseaudio while pipewire is the next generation.

Update grub, 

grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
