I have 3 independent Cloudstack installs. One is 3.0.x and the others are
4.1.0.
Using KVM (i'm only using KVM so I don't have anything else for
comparison), between 3.0.x and 4.1.0 I'm getting instances with UUID's that
are the same.
I get the UUID by running this on the console (CentOS):
dmidecode -s system-uuid
Here is example output from 1 host:
[root@fortress ~]# dmidecode -s system-uuid
C1260F04-F171-3136-85A7-F0B77699DA33
[root@fortress ~]# ifconfig eth0

here is another:

NOTE: The IP's are not in the same nor in the same subnet
The time between creation is pretty long... weeks.
Any ideas?
I've just been killing VM's that have collisions with UUID's but it happens
pretty often.
