Thank's for the answer. Now I understand the difference!
But after using "--devices", when I try:

# vzctl set <VEID> --devices b:8:18:q --save
# vzctl enter <VEID>

it gives this message:

# vzctl enter 120
Invalid value for DEVICES=b:8:18:, skipped
entered into VE 120

Like you said, I have no access with "fdisk /dev/sdb", but i can "ls /dev/sdb".
If I do:
# vzctl exec 120 rm -f /dev/sdb

it answers the same message:
invalid value for DEVICES=b:8:18:, skipped

but it deletes the devnode. So it reverts to the initial situation.
Is this message (...invalid value...) ok? Is this the right way to do it?

The other example (--devnodes) has also some problems:

# vzctl set <VEID> --devnodes sdb:none --save

the argument "none" doesn't delete the devnode in /dev/sdb (or is it supposed to only disable grant access?)

The only way I can revert to the original situation (without a devnode) is changing the file:
/etc/vz/conf/VEID.conf
and deleting the devnode manually.

My vzctl version is 3.0.14-1.

The question boils down to this:

After creating and granting access to a devnode, what is the most correct way to revert to the prior situation?
It seems the examples you gave, don't work the way I expected.

Thanks

M.C.
