Good news to everyone. Finely i found a way to use several IP on different MAC on only one NIC. I tried:
* multimac
* macvlan #ip link add link eth0 name vmaclan0 address 00:aa:bb:cc:dd:dd type macvlan
but no one of them gave exactly what i wanted. So after break I started to look again and I found macvlan updates starting from 2.6.33 kernel [ source ]. I downloaded kernel source code from Proxmox but seems it still not patched. Later I will try to patch kernel to 2.6.32-4-pve state and then to apply macvlan patch. I do not have good experience with it so if Proxmox team have a free time to help me with it I will be very pleased.
