Re: [Xen-API] Installing OpenStack Grizzly on CentOS VM running on XenServer

[Mate Lakat <mate.lakat@xxxxxxxxxx>]

Hi,

The blogpost's third point is:
cd xen-4.2.0/tools/
and the fourth is the patching
That means, that you are in the xen-4.2.0/tools/ directory.

If the configure script reports errors, you need to fix them, it usually
means, that some libraries, header files are missing from your system,
or cannot be found. In your case, the "Unable to find as86, please
install as86" suggests, that you need the as86 package to be installed
on your system.

In those cases, I usually perform these steps:
 - yum search <package name/binary name (this case as86)>
 - do a google search on the error message
 - do a google search on the error message + my distributions name

By reading the search results, you sould be able to find out, which
package contains the required binary. In my case, as I am using Ubuntu,
it turned out, that the name of the package that needs to be installed,
is "bin86". As you are on Centos, you might try dev86 as well. You might
get some pointers by searching how to build Xen on CentOS, as we are
actually building some parts of Xen (the tools), so those pages might
contain useful information.

Regarding to the faketime package, you will have to do the same. Just to
give you some background on why the faketime is needed:
The vhd file contains a timestamp, which is a simple local time. So, if
your machine, that you use for conversion is on a different timezone
than your xenserver, the local times can differ. This way, after you
transfer (or as OpenStack transfers) your image to the XenServer, it
will perform some checks on it, and it might think, that the file was
created in the future. That is counted as an error, so you won't be able
to use your bits. That's why I used faketime, to fake the local time
back to the past, so that I don't face with that problem.

I hope that helps, and let me know, if you have any other issues.

Happy Stacking with XenServer!

Mate
