Citrix Xenserver and FreeBSD migration/suspend scripts

[Mark Felder]

I've had a few positive responses off-list about this and the desire to  
get this into the ports tree somehow. Someone also had the original  
author's email address (he subscribes to this list), so I'm going to CC  
him on this email as well.

We could probably get this into the ports tree relatively quickly. I've  
been working closely with the ports@ team recently, so it wouldn't take  
much effort in that respect. Some questions were brought up about what it  
should be named or if it should be a separate port and I don't know what  
the right answer here is, really. Perhaps emulators/xe-tools or  
emulators/xenserver-tools would be sufficient.

I guess the first step would be to find some place to officially host the  
tarball and/or tag a release on github. As it stands things are fully  
functional, so getting this into the ports tree shouldn't be too big of a  
problem. Long term I'd like to see this cleaned up a bit more... it's  
quite the mess. Honestly, everything could (and should) be rolled into one  
shell script because there's really no need to have xe-daemon,  
xe-ip-if.sh, and xe-update-guest-attrs. For the record,  
xe-update-guest-attrs is the file with the Citrix/GPL header. It has the  
examples of how we should be calling the other xen-tools to report data to  
XenServer. Whether we concentrate on this script or a rewrite happens  
doesn't really matter to me; it's not a lot of code I'd just like to see  
all of these really awful hacks removed :-)

Someone was asking about whether or not this was production-worthy. I  
really don't see why not. I suppose if this fails you'll just end up with  
a VM running without recognized tools again. I don't believe it's possible  
for the OS to crash from things these scripts run, and the ability to  
migrate/suspend Xen VMs is not reliant on these tools in a fully open  
source Xen environment; this is just a requirement Citrix imposes.


Feel free to speak up if you have any thoughts or suggestions :-)


Egoitz, can you confirm what license you originally released everything  
under? I'd like to properly honor that license if you had one in mind.
