I'm trying to assign eth0:2 to a vps, but I can't seem to figure it out

mainserv bradley # ifconfig eth0:2
eth0:2    Link encap:Ethernet  HWaddr xx:xx:xx:xx:xx:xx  
          inet addr:xxx.xxx.xxx.xxx  Bcast:xxx.xxx.xxx.xxx Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          Interrupt:11 Base address:0xc000

mainserv bradley # vzctl set 101 --netdev_add eth0:2
Unable to add netdev eth0:2: No such process

Is there a way to do this?

No, you can only give a real network device to a VPS.

BTW why do you need this?

It is a dedicated server that I don't have physical access too that has one network card buy multiple IP's, some that I wish to map directly to the vps

Well that's pretty straightforward.

What you need to do is
(1) remove those extra IPs from eth0 interface (leaving just the one address for the server itself);
(2) add those IPs to the appropriate VPSs, i.e.

vzctl set NNN --ipadd a.b.c.d --save

that's simple enough. I had alredy assinged the IP to the VPS, but, this was helpful. thanks

Ok, now I'm stumped again.
I removed eth0:2 from my network config. The IP was already assigned to the vps. The vps starts fine. I go to ping the IP and I get no response.

I do have /etc/sysctl.conf set up according to the quick install directions (however they are not in the gentoo howto)

I'm using Gentoo, which I figure probably makes this crap out on me

I sorted it out, it took some playing, but I got it to work.

The primary and secondary address I have use a different default gateway, I just had to make the vps know this
