 ====== Proxmox - Guests (VMs and Containers) ======
+VMs are virtual machines powered by [[https://www.qemu.org/|QEMU]]:
+  * Separate OS.
+  * Completely separate kernel.
+  * Completely isolated from the host OS.
+  * Some additional overhead.
+  * Devices such as GPUs, drives or USB controllers have to be passed in entirely.
+  * Limited support for passing through single HDDs, but not recommended.
+[[https://linuxcontainers.org/|LXC containers]]:
+  * Share the same kernel as the host.
+  * Less overhead.
+  * Greater performance.
+  * Constrained to only being Linux, but any distribution.
+  * As LXC processes use the same kernel, it means sharing access to things like GPUs and storage is significantly easier, and with less overhead.
+  * To access storage on the host, just bind mount it in with almost 0 overhead - No PCI pass-through necessary.
