[Users] creating partition for VE and networking

[Markus Hardiyanto]

i want to make separate partitions inside the VE, is that possible?

so instead of getting this:

> Filesystem            Size  Used Avail Use% Mounted on
> simfs                 1.0G   95M  930M  10% /

i would like to see something like:

Filesystem            Size  Used Avail Use% Mounted on
simfs                 1.0G   95M  930M  10% / 
<something>      2.0G   20M  1.9G   1%  /home
<something>      75M    8M     67M    1% /boot

virtual partition i say.. this is not the hardware node partition, but in the VE

i check it and can't find it. but i found: /proc/sys/net/ipv4/ip_forward and it have contents "1"
but still the VE can't be pinged from other computer.
 
Best Regards,
Markus

I don't quite understand what do you want? =) In order to mount some 
filesystem on any directory in VE just use usual mount. However the list 
of filesystems, that you can use in VE is limited (look at 
/proc/filesystems in VE, sysfs and nfs can be added via `vzctl set 
<veid> --features` command).

Every real fs is deployed on some device. Usually VE doesn't use such 
devices (like /dev/sda1, ...). But you can give VE an access to the 
device via `vzctl set <veid> --devnodes`. Note, that this is the same 
device, that is on your host node: some partion on your HN for example, 
  so deleting files from it will remove files from the host.

check, that /proc/sys/net/ipv4/ip_forwarding contents "1"
