I'm can't seem to create a veth device on my VE I get and error of "Bad parameter for --veth_add: eth101.0"
My specs:
HostOS: CentOS 4.4
kernel: 2.6.9-023stab037.3-smp
My VE is Ubuntu Dapper (used the minimal install from this site)
My host OS reports (via ifconfig) 3 devices:
eth1 - which has a IP and MAC address
lo - my loopback
venet0 - no ip and a MAC of all zeroes
The how to for setting up a veth (http://wiki.openvz.org/Veth)
says
$ vzctl set <VEID> --veth_add dev_name,dev_addr,ve_dev_name,ve_dev_addr
where "dev_name" is is ethernet device name in the host system.
Ok I understand I have to create a virtual devicce on the hostOs and a corresponding device on the VE -
however when I do
$ vzctl set 101 --veth_add veth101.0, a_made_up_MAC_address, eth0, a_made_up_MAC_address+1 --save
I get the "Bad parameter for --veth_add: eth101.0," error message.
What am I missing? Errr stupid question - do I need to install another NIC on my host system? Or do I just make up a MAC address? I tried using the MAC address of eth1 (the existing NIC on the host system) with the same results.
Also am I right in thinking I need to use a veth device (as opposed to a venet) to run a DHCP server in a VE?

Sorry not sure I understand you...
"As I can see in your commndline "eth0" persists"
do you mean
$ vzctl set 101 --veth_add veth101.0, a_made_up_MAC_address, eth0, a_made_up_MAC_address+1 --save
the eth0 in the line above? Isn't this the virtual Ethernet device which I'm creating?
Or do you mean the ".0" part of veth101.0? I just copied the format from the wiki and assumed the same format.

As I can see you have spaces in this line after commas, please try following command:
$ vzctl set 101 --veth_add veth101.0,a_made_up_MAC_address,eth0,a_made_up_MAC_address+1 --save

Yes, you need to add veth device to VE to be able to run DHCP server in it.
