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:
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

- /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/

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
