Hyper-V

Installation

VM Machine type:

1: Use for older ISOs, avoiding "the signed images hash is not allowed (db)"
2: Use for UEFI/Secureboot

Convert VMware to Hyper-V with qemu-img:

qemu-img convert -p -f vmdk -O vpc centos_disk.vmdk centos_disk.vhd

Proxmox

Main documentation:

Proxmox

Installation

hdsize defines sieze of disk, to reserve space for additional VGs
minfree defines unallocates space in the VG, required for LVM snapshots (hdsize/8 to a max of 16 GB)
VG "pre" is created with LVs:
- root (define with maxroot, limit is hdsize/4)
- data (maximum defined with maxvz: hdsize - rootsize - swapsize - minfree. Must be at least 4 GB)
- swap (define with swapsize)
For HP DL380G5 (and other on VGA?) blank screen during install:
- Edit "e" -> add "nomodeset" and/or "i915.modeset=0" as Linux kernel option

To enable updates, add:

# Proxmox VE pve-no-subscription repository provided by proxmox.com,
# NOT recommended for production use
deb http://download.proxmox.com/debian/pve bookworm pve-no-subscription

# security updates
deb http://security.debian.org/debian-security bookworm-security main contrib

to the file:

/etc/apt/sources.list

Then update:

apt dist-upgrade

Windows VirtIO drivers:

Windows VirtIO drivers

Network configuration:

/etc/network/interfaces

Time Server:

/etc/chrony/chrony.conf

Storage

Initial storage:

local
- LV: pve/root
- mounted under /
local-lvm
- Thin LV: pve/data

ISO Uploads:

/var/lib/vz/template/iso/

wipefs -a /dev/sdb /dev/sdc
pvcreate /dev/sd[bc]
pvs
vgcreate main /dev/sd[bc]
vgs
lvcreate -T -l 100%FREE --poolmetadatasize 1G main/vm
lvs -a

VirtualBox

When running on Linux, ensure KVM module is not loaded:

rmmod kvm-intel
rmmod kvm-amd

XCP-NG

Installation

Options for storage:

ext -> for thin provisioning
LVM -> for thick provisioning

Update to latest packages:

yum update

Deploy XOA (Xen Orchestra VM) to manage this and other XCP servers in one place.

VMware

ESXi

At install time:

SHIFT-O
runweasel allowLegacyCPU=true
