[Xen-users] XCP 1.0 beta - domU boot: unable to retrieve network based images
Hi Folks:
Please help if you can. I am stuck. I am trying to do a network based
install of a CentOS 5.5 (64 bit) image using XCP 1.0 and got this error:
I have verified that the network images can be accessed on other hosts.
Then I tried doing the same install with XCP 0.5 and got the same error
which means that I am probably missing some simple, fundamental step.
Maybe I am using the wrong UUID in one of the steps.
Here is what I did to create the VM. What am I doing wrong? Please note
that this work was done on a master (10.45.2.1) that communicates with
the XCP host (10.45.2.100).

Have you tried those? One other thing to check is that your VM is connected to the right network. Hope that helps.

Hi Todd: Thank you for your help.> One possible helpful reference:http://www.xen.org/files/XenCloud/guest.pdf Yup, I have read that document. Unfortunately, at item 6 on page 26 it says "VNC and perform the OS installation" which is where I got stuck.> I''ve installed from the Clarkson mirror successfully, this is the URLthat I use: http://mirror.clarkson.edu/centos/5.5/os/x86_64/ Great, I will try that.> Typically, I install with openxenmanager or xenwebmanager. Have youtried those? Nope but I will try them today.> One other thing to check is that your VM is connected to the rightnetwork. That is a great suggestion and is probably the source of the problem. Unfortunately don''t know how to do that. I have verified that the dom0 VM server is on the right network but how can I check the domU VM while it is booting?> Hope that helps.It does. Thank you again for taking the time.

Unfortunately don’t know how to do that. I have verified that the dom0 VM server is on the right network but how can I check the domU VM while it is booting?The most low-level was is to use the command brctl show. There are Open vSwitch commands and xapi (xe) calls, etc. but that is a lesson for another day. OpenXenManager and other tools will have a graphical way to view the network settings. Hope that helps.
