OpenNebula

Before you start .. make a backup of you actual opennebula install:
cd /; tar cpvPj -f ~/opennebula.1.4.backup.tbz2 /{etc,usr/lib,} /var/lib/one/{.ssh,one.db} /usr/bin/{one,occi,econe,mm_sched}

1. one start; sleep 10; one stop
   [The next step will create mysql inserts from the one.db]

1. ORIGINAL_DB=/tmp/one.db # the path to your one.db - remember: make a copy of your database!!
2. DEBUG=true # if true informs on every db access, will redirect debug from STDOUT to STDERR.

make gts.sh executable.
execute ./gts.sh and pipe STDOUT to a file like /tmp/opennebula.inserts.sql.

1. mysql -D opennebula;
2. source /tmp/opennebula.inserts.sql
   (history may have some unique key issues, this is not a problem!)

1. Delete /tmp/one* on every host (follow issue http://dev.opennebula.org/issues/385, too).
2. start one : $ one start;
3. test onevm, onehost, etc.
   If all was fine you now have a running opennebula 2.0.1,
   else:
4. stop one
5. drop the opennebula database (!!)
6. restart from above, something is wrong with vm_pool.template or host_pool.template, or I messed with my scripts and you may search for another migration path.

I wish you good look.
I had it.

Best regards

Forget this part.. bad bad tar command... make a backup, you know!!

I can confirm your scripts worked for me. Thanks a lot.

Thanks Shi Jin for you courage ;)
So .. today I take my courage and did the migration.
Somethings had changed on opennebula between the version from 1 Month ago to today, so I had some problems.
I will report every one of them and repost new scripts, stay tuned.

Don't use the above scripts under the version 2.0.1-1(Actual download)!!

VMs created on opennebula_2.0-1 fails to restart under opennebula_2.0.1-1
