[pve-devel] [PATCH pve-manager 2/2] ui: fix: change units of memory/swap for containers

[Noel Ullreich <n.ullreich@proxmox.com>]

This patch adds a dropdown-menu (in the web interface) of units, MiB, GiB,
and TiB, (although PiB could easily be added in the future) for ram
and swapsize of containers.
