Thanks Jon,
it worked, I was able to build all the packages for xenserver on CentOS 6.6 final version.

Here is the package list: https://gist.github.com/gautammaloo/7616cccbe8f5c85c196e 

I was wondering what packages would be necessary to use Xen with xapi, I already have xen with xl installed. Could we have a package like http://packages.ubuntu.com/precise/xcp-xe with which we can have  xenserver running on CentOS, just by switching toolstack from xl to xapi. 

Best regards,
Gautam Malu

Hi Gautam,

>From the log it looks like it ran out of space - this could be the disk being
full, but it could also be that it might be building in a tmpfs environment
and you're actually running out of memory.

try changing the mock config in buildroot.git/mock/default.cfg - the line is:

    config_opts['plugin_conf']['tmpfs_enable'] = True

change that to 'False' and see if that helps.
