Hi,
Could you check if firewall and selinux on in your xCAT management node?
xCAT uses HTTP heavily during booting, but if you use firewall and selinux, the HTTP server cannot serve files from /tftpboot .
Best Regards

Hi again,Here is some details about my lab test.My physical machine is a Fedora 28, I have created on it two VMs, A manager and Compute node using CentOS 7.5The problem is as described previously, the vmlinuz does no get downloaded using xnba or pxe.I made another test, I used nested KVM to create a CentOS 7.5 hypervisor then on top of it i created one Compute VM.This time when using pxe, the vmlinuz get downloaded at 66% then it freezes, but when using xnba the VM completely freeze and I get this error on libvirt logKVM internal error. Suberror: 1

Subject: [xcat-user] Problem deploying compute node, vmlinuz not being downloaded
Date: Wed, Sep 5, 2018 7:41 AM
Hi,I am newbie in xcat, and I am trying to deploy my first compute node but without success.First of all, excuse the statement, but the documentation is a mess (sorry).My lab is pretty simple, I am using VMs for the management node and compute nodes.I made abstraction of BMC configuration and I didn't use xcat with KVM, the idea is to simulate physical deployment.I am using Centos 7.5 as OS for MN and CN.I boot the compute node manually in PXE boot.The problem : the PXE boot works fine until the download of the vmlinuz image and it hangs, and nothing after.In http access_log I can see the GET of the vmlinuz request, but nothing happen, I waited 10 minutes, and nothing.I tried with wget from another host, and the file vmlinuz can be downloaded without problem.Any ideas?Regards.------------------------------------------------------------------------------
