[Xen-users] IP-Address for DomUs via configuration script possible?
Hello everybody. I got the following problem: I want to assign the ip-adresses for my domUs dynamically. I mean that i can assign them while creating them so that i dont have to login to the virtual machine to assign it. I dont have any Dhcp option because then i wouldnt know how to connect to the DomUs (which ip to use to connect to them). I solved this problem with xen-tools and debian but i need a solution for Windows XP and Vista. The sytems are running but i tried to configure via the configurescript (windows-xp.hvm and vista.hvm) with: vif=[''ip=192.168.1.22''] but i couldnt connect to the virtual machine. The DomU (winxp) was configured to get its ip from dhcp cause i need to clone every machine via cp and so i can not assign the machine (in the image) a static ip... I thought that it could be possible to assign via the configuration script to assign a domu an ip and the domU gets this from xen when it tries to get a dhcp offer... any suggestions? regards Alexandros _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Re: [Xen-users] IP-Address for DomUs via configuration script possible?
Hi,
I would try to put a MAC address in domU config file (XEN has his own
MAC range),
vif = [ ''type=ioemu, mac=00:16:3e:00:00:11, bridge=xenbr0'']
and configure your DHCP server to assign a known IP address to this
MAC. For example:
host Windoze1{
hardware ethernet 00:16:3e:00:00:11;
fixed-address 192.168.2.101;
}
Regards,
Marc

> vif=[''ip=192.168.1.22'']afaik, this is a linux-specific option. Suggest you give a fixed mac-address to the domU and make your dhcp server assign a fixed ip-address to that mac address.

Re: [Xen-users] IP-Address for DomUs via configuration script possible?
Hello again and thanks for the fast answer. But i think u misunderstood me. I do not have access to the DHCP. I give you the scenario: i want my clients to have the possibility to create DomUs (windows-xp-machines) via a php-script. They click: "create" and the new xp-machine gets created. BUT they need access to this machine via Remote Desktop and so this new just created machine needs a IP. So the possibility you told me needs a lot of configuration. I need to set up a DHCP on the dom0 and create dynamically new mac-addresses for the domus (thier config-file) and also edit the configurationfile from the dhcp of the dom0. BUT i dont want to set a dhcp on the dom0. I want to have the possibility to assign the ip-address via a script or sth. like that... regards Alexandros Marc Patino Gómez schrieb:> Hi, > > I would try to put a MAC address in domU config file (XEN has his own > MAC range), > > vif = [ ''type=ioemu, mac=00:16:3e:00:00:11, bridge=xenbr0''] > > and configure your DHCP server to assign a known IP address to this > MAC.

Why is DHCP not an option for you? As long as you assign the mac address everything will work as planned? Stefan _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Re: [Xen-users] IP-Address for DomUs via configuration script possible?
Because i dont want to install any dhcp-servers on the dom0. I want to keep the dom0 for everybody that will use the phpscript to create a domU as simple as possible. Dont want anybody to read the install-instructions and have there 30 steps of things to do to get the script running. There might be a way i thought just about. IF there were another DHCP (outside of the dom0) the clients could request a IP. The problem is that the user that created via the phpscript the domU doesn´t know about the ip the domU just got. To solve this i might need a script (perl or sth. like that) that monitors the dhcp-offers from any machine on the dom0 (listen on the bridge) and stores the answers from the outside dhcp in a database or txtfile and gives this to the phpscript back so that the user gets the IP to connect to.

Don''t re-invent the wheel, use DNS. Just have your users pick a host name when they create their domU. Dnsmasq (http://www.thekelleys.org.uk/dnsmasq/doc.html) is a lightweight app that provides both DHCP and DNS services all in one package. This can easily run in dom0, or a domU specifically set up for the purpose. regards, Richard. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
