Hi,

try the following commands

# vzctl set $VEID --devnodes mem:rw --save
# vzctl set $VEID --capability sys_rawio --save

Quote:

I also have a question about mknod, what's the difference when /dev is created from mknod and device being passed by vzctl set 2005 --devnodes?

mknod simply creates device file inside VE but vzctl says to kernel that the particular VE is going to have appropriate permissions.
