When I went to add an iSCSI target on Proxmox for virtual machine and image storage, it was a bit confusing. To use TRIM in a virtual machine together with Proxmox, the following conditions must be met: A thin-provisioned backing storage (qcow2, thin-lvm, zfs, ) Virtio-SCSI disks with the discard option enabled; To achieve this goal with Proxmox, you simply have to change the virtual machine settings:. Note: As of late 2012 new tools have been added to cryptsetup to add or remove encryption to/from an existing file system. You cannot remove a virtual disk if the virtual machine is suspended. container, Docker, LXC, Proxmox Proxmox / LXC - Running docker inside a container In relation to Debian / Proxmox – Install Docker with Rancher and DockerUI webgui on a Debian / Proxmox Server I thought that it actually may make more sense to run Rancher and my docker inside an LXC container rather than on the initial host itself.
