[Xen-users] XCP assigning VMs static IPs before they''re started
Hello, I''m trying to figure out how to give a VM a static IP before it''s been started and without having to modify any of the VM''s network startup scripts. In looking at XenServer examples people recommend doing something like this in the configuration file: vif=[''ip=192.168.0.100'',bridge=xenbr0] That doesn''t seem to be an option in XCP with the CLI with xe vif-create. What am I missing here? Any help is appreciated. Maybe this is a networking question non-specific to Xen and I don''t realize it. I''m using 0.5. Also, if anyone can point me to some good documentation/tutorials on XCP networking that would be great. So far I''ve looked through all the stuff in http://www.xen.org/files/XenCloud/ and http://wiki.xensource.com/xenwiki/XenNetworking.

Since you''re using bridging, XCP doesn''t assign IPs, period. The only thing it could possibly do with the IP is to firewall it to make sure the VM isn''t trying to use a different IP. Maybe you''re talking about passing the IP as a boot argument that the network scripts pickup? In that case, you''d want to add it to the PV_args setting. -Dustin On Mon, Apr 4, 2011 at 11:43 AM, Chris Dickson <chrisd1100@gmail.com> wrote:> Hello, > I''m trying to figure out how to give a VM a static IP before it''s been > started and without having to modify any of the VM''s network startup > scripts.

Re: [Xen-users] XCP assigning VMs static IPs before they''re started
Just a thought - and maybe an irrelevant one... Can you set the MAC address for the VM, and put a reservation in your DHCP server?
