+#I am using the sys-usb VM for GPG here because I am using a PGP smartcard. You probably shouldn't do this if you store your GPG private key on disk. It **might** be safer to still have a dedicated gpg-backend VM for this, but then you will have to reassign the smartcard to the VM after every boot, which could be annoying.
