I have installed fedora core 4, followed up with the install of OpenVZ. Everything seems to work well; however, I have a need to use dhcp rather than static IP addresses. Can I configure a VPS to use dhclient rather than a static ip address? If so how? I tried to: # vzctl enter ### # dhclient venet0 The guest was never able to contact the dhcp server. My VPS is also fedora core 4. Thanks! eanxgeek
Hello Eric, you are the first who wants such configuration :), but I suppose it is possible to do it if better understand what you are doing and what are your goals. Do you want your VPSs to be accessiable outside from the network? 1. If the answer is "no", then you can setup any local IPs to VPSs and configure NAT in the host system. Thus your VPSs will have local IPs, will be able to connect to the network, but won't be accessiable from outside (though you can map one specific port of the host system to VPS port, i.e. can make VPS http server to appear on some specific port of host system IP). 2. If the answer is "yes", then I suppose there is definetely something strange in your configuration, since DHCP can bring you arbitrary IP address and you will have to have some DNS tricks or otherwise you still won't be able to determine VPS IP easily from the outside. But the good news is that it is possible to do either :) I have no dhclient on my machine, but dhcpcd I use here accepts -T option which allows (as follows from man page) to get multiple IPs without setuping them on the interface itself). So you will need to write some simple script which will reserve IP addresses from DHCP this way and configure them on VPS with `vzctl set <VPSID> --ipadd <IP>` command. Remember to delete previous VPS IP before adding a new one. Hope this will work for you, Kirill(Continue reading)
My intent is to have my guests (VPS systems) be avaialble to the network without using iptables, SNAT, or NAT to forward packets. I am using fedora so I have dhclient available to me and not dhcpcd, at least not with my package base. Anyone know how to "grab" more than one IP address from a DHCP server using dhclient. There is no -T option.

First, let me start by stating I am fairly new to OpenVZ. Now, last night I tried to use the pre packaged template for Fedora-core-4-default, which worked fine, then I attempted to install vncserver + X11. These installs all seemed to work fine, I did notice that a new fedora kernel was installed. Well, at some point I decided to vzctl restart <vpsid> and it seemed the image started, but I could not access it via ssh or vzctl enter. When hardware 0 reboots it shows OpenVZ starts, but that VPS 101 fails to start. So any idea how I might set up X11 under a VPS? Also, along the same note, is there a good reference on how to build my own template? Thanks!
Eric, First, when submitting a bug report or a problem description please always try to be as specific as possible. In this case it would be helpful if you tell exactly the packages you have installed, the commands you use to do that etc. Second, the problem is xorg-x11 requires kernel-drm thus kernel is about to be installed but it conflicts with our 'dev' package. If you have used vzyum or yum it just bails out telling there is a conflict. Anyway, to solve the problem some trick is needed. The trick is to have a package installed which claims it provides kernel-drm = 4.3.0 so xorg-x11 dependencies will be satisfied. So I have an updated version of dummy package (which is created just for those tricks) that does just that; it is attached. What you need to do with it is: 1. Place it to /vz/template/fedora-core/4/i386/vz-addons/ directory. 2. cd to that directory and run createrepo as root (if you do not have createrepo installed you can take rpm from http://linux.duke.edu/projects/metadata/generate/) 3. Update template cache by running vzpkgcache (check that this very version of dummy package is put into cache), then create a new VPS and go on from there (vzyum VPSID install xorg-x11 vnc-server). Restoring your existing VPS would be a bit more complex... Eric L. Sammons wrote:(Continue reading)

Kir, Thanks for all of your help and valuable information. As a learning exercise I too am trying to build my own fedora-core-4 templates using RedHat's "server" install as a baseline I noticed the dummy package you mentioned below, but I also noticed vzdev throws things off a bit as well. It advertizes the 'dev' capability without a version. RedHa't own udev specifies a version of 3.2-7 and some packages request that. I ended up going through a painful exercise of iteratively removing packages from my template's .list file and an exclude statement in my yum.conf to get around the conflicts. Would it be possible to get the spec files for both packages?
