hi,

im playing a little bit with some machines and i've found a problem that i'm not sure if it's a bug.

i've modified container conf:

Code: 
VE_ROOT="/mnt/sambatemp/vzbase/root/134"
VE_PRIVATE="/mnt/sambatemp/vzbase/private/134"

then when i try to start the node i get an error:

Code: 
vzctl start 134
Starting container ...
vzquota : (error) Quota on syscall for 134: No such file or directory
vzquota on failed [3]

digging a little bit i've found the problem on vzquota. it seems to be looking for private directory in /var/lib/vz/private instead of the one i've specified in conf file.

Code: 
strace -f vzquota on 134

private dir seems to be harcoded. is this a bug?

if i delete /var/lib/vzquota/quota.134 machine starts ok so im not sure if i can recreate this file reflecting changes i've made to conf file.

i've just found the problem. quota file had private dir harcoded, so i just removed /var/lib/vzquota/quota.134 and started container.

everything seems to be ok now.

is there any other problems i can face?
