util-vserver cheatsheet

ok,

here is my cheatsheet for util-vserver. I figured a lot by hand so i would like to share some here. This is a draft:

How to add an IP address to a guest

1. create the address on the host:

   ifconfig eth0:10 172.16.0.145/12

   or

   ip addr add dev eth0 172.16.0.145/12

   or even

   ip addr add dev dummy0 172.16.0.145/12

2. add the adress:

   naddress --nid guestname --add --ip 172.16.0.145 --bcast 172.31.255.255

   • Depending on what you use the vserver for, you may not want the broadcast thing at all; you can also use a /32 mask for the IP in this case.
3. add the ip to the config directory to make it stick if you restart
4. enter the guest and verify services that need to listen on the ip, restart if necessary (for me it was not).
