Can You Convert an LXC Container to a VM in Proxmox VE? What Actually Works
There's no button for it. Here's why Proxmox VE can't turn a container into a virtual machine in one step, what the unofficial workarounds actually do, and the safer path most people should take instead.
How to Migrate a KVM/libvirt Virtual Machine to Proxmox VE (Step-by-Step Guide)
Move an existing KVM/libvirt VM to Proxmox VE without rebuilding it. Pull the specs with virsh, copy the qcow2 disk, and import it with qm disk import.
SeaBIOS vs OVMF (UEFI) in Proxmox VE: Which One Should You Choose, and How to Switch Safely
The BIOS dropdown in Proxmox's Create VM wizard picks legacy SeaBIOS or UEFI-based OVMF firmware. Get it wrong and Windows 11 won't install, or an existing VM stops booting. Here's what each option does and how to switch without breaking a VM.
Can You Run macOS on Proxmox VE? What Actually Works (and What Apple's License Says)
Yes, macOS can boot as a Proxmox VE guest using OpenCore and QEMU's Apple SMC emulation, but it's unsupported by both Apple and Proxmox. Here's the real setup process, the CPU flags it needs, and the errors you'll likely hit.
How to Automatically Schedule VM Snapshots in Proxmox VE With Cron (No Built-In Scheduler Required)
Proxmox VE has no built-in snapshot scheduler, only backup jobs get one. Here's how to automate regular VM and LXC snapshots yourself using qm, pct, and a simple cron job, plus how to prune the old ones automatically.
How to Fix a Proxmox VE VM That Won't Start (TASK ERROR Messages Explained)
Your Proxmox VM won't start and the task log just says TASK ERROR? Here's how to read the real error underneath, and fix the missing disks, full storage, and low RAM that usually cause it.
How to Use KSM (Kernel Samepage Merging) in Proxmox VE to Save RAM on Multiple VMs
KSM quietly deduplicates identical memory pages across similar VMs on a Proxmox VE host. Here's what it actually does, how to check if it's saving you RAM, and how to disable it node-wide or per VM.
i440fx vs Q35 in Proxmox VE: What the Machine Type Setting Actually Does (And When to Change It)
Proxmox VE hides a chipset choice under Options → Machine that most beginners never touch. Here's what i440fx and q35 actually change, why PCIe passthrough and Windows 11 care, and how to switch safely.
How to Create a Windows Server 2019 VM in Proxmox VE (Step-by-Step Guide)
Windows Server 2019 still works great as a Proxmox VE guest, but the VirtIO storage driver step trips up almost everyone. This guide covers VM settings, the driver load screen, and getting the QEMU Guest Agent talking to Proxmox afterward.
