ok retrying and sorry about the english what im trying to do is add my 2TB HD as storage so both of my windows VM can view them also have files on that 2TB HD so dont want to dele them

So, as far as I understand, you have a computer with 2 hard disk. In the first one you have installed Proxmox, and the second one, of 2TB containing lot of files you don't want to loose, have to be seen by both Win VM, right?
The only solution I can think of is install samba in Proxmox (in proxmox host itself), mount your 2TB somewhere (i.e. /srv/smbshared) and create a share of that directory using samba. This way you can see, from both your Win VM, that as a network driver (and then map it, i.e., as D: or whatever).

Hi,
i prefer not to install samba on the host. You can install samba on a linux-guest to provide the data to the other hosts. If you have only a single node (or all clients for the data on one node) you can use a dummy-bridge without real NIC for faster throughput.

Hi Udo, could you please elaborate the "dummy bridge" stuff? How to set it up? Could be useful for me for build some test environment where only VM traffic is involved.
Thanks

Hi,
a dummy bridge can you create in the following way:
in /etc/network/interfaces:

...
auto vmbr0
iface vmbr0 inet static
        address  192.168.220.10
        netmask  255.255.255.0
        gateway  192.168.220.1
        bridge_ports eth0
        bridge_stp off
        bridge_fd 0
        post-up /usr/local/scripts/generate_vmbr10.sh

/usr/local/scripts/generate_vmbr10.sh : (chmod +x)

modprobe -o dummy0 dummy                                                                                                                                                     
ifconfig dummy0 up                                                                                                                                                           
brctl addbr vmbr10                                                                                                                                                           
brctl addif vmbr10 dummy0                                                                                                                                                    
ifconfig vmbr10 up

Hi,
on way:
if you use kvm-only (no OpenVZ) you can do a normal install, then install the second blank!! disk - create a partitiontable on the disk with type 8e (lvm).

pvcreate /dev/sdb1
vgcreate -s 4M vmdata /dev/sdb1
vgscan

After this you can add in the storage menu this as lvm-storage. If you select during vm-installation this storage for client-disks your vm-disks will created as logical volumes on this volumegroup. Voila - your data are on the second disk.
