Hi "M.C.",

imho both option are used to grant access to some /dev -files in VE0, but with option "--device" device-node in /dev/ can be exist and option "--devnode" the dev-node in /dev *must* be exist !

in your example:

// grant access to existing dev-node in VE0
// and create automatically a devnode in VE
# vzctl set <VEID> --devnodes sdb:rw [--save]

// disable with none
# vzctl set <VEID> --devnodes sdb:none [--save]

the same command with --device :

// first create devnode in VE
# vzctl exec <VEID> mknod /dev/sdb b 8 18
# vzctl exec <VEID> chmod 600 /dev/sdb

// grant access to VE0, without creating a devnode in VE
# vzctl set <VEID> --devices b:8:18:rw [--save]

// disable grant access with q
# vzctl set <VEID> --devices b:8:18:q [--save]

vzctl option "--device" can be used, but missing infos in documentation and man pages.
