XenCloud, Xapi and FreeBSD

Good morning,

I would like to make a suggestion from this mailing list.

I'm working at an ISP environment and we're running Xen Cloud as
virtualization infrastructure. For a large number of years we have been
running FreeBSD (an nowadays... we run it too...).. although FreeBSD
seems to run pretty nice under XenCloud (with XENHVM kernel) the
interacion with xapi and XenServerTools are not supported for this
(IMHO) nice operating system. It gives so much possibilities to
experienced sysadmins that I think that other OS like Centos (for
example) are totally in clear disadvantage with this BSD Os (for some
several reasons which I could debate in other moment). So I would to
suggest from here to add support for FreeBSD at XenServerTools and to be
able to take advantage of this fine api with this fine OS.

Is it planned to give FreeBSD support to xapi?. If not, I could try to
take some time for trying to write it.

Thank you very much for you're time.
Best regards,

Hi,

I'm not aware of anyone trying to port the tools to FreeBSD. However, it should be quite simple because the tools are just a couple of shell scripts which write to xenstore (using "xenstore-write")

So I think you would need to:

1. Make sure the "xenstore-*" commands work (you might need to set an environment variable first, to allow them to find the right kernel device)

2. Customize the Linux shell scripts -- they need to know how to get the VM's IP addresses etc (replace eth0 with xn0?)

3. Make sure the scripts start up as a system service

4. Contribute your work o the FreeBSD ports tree?

HTH,
Dave

Including for stoping the virtual machine, sleeping, moving to another
host and so Dave?. Xentools port is available for FreeBSD so I assume
this could be.

Any kind of test I could do?? Till the moment FreeBSD is running quite
nice at the XCP apart of the fact is not having XenServerTools
installed... but yes Xentools and XENHVM kernel.

There's no problem on that....

No problem too....

Of course!!! this is important for those who love FreeBSD for they're
servers!! It's not the same working mode as don't know Debian for
example... or Centos... and some people manages much more better with
FreeBSD...

so just shell scripts you say??
