Subject RE: 4.x for production
Date Fri, 21 Dec 2012 11:07:29 GMT
Did you upgrade and are you using usage info for billing? There is bug reported that the network
usage is wrong.
Did you notice when your system-vms are gone then the system will not re-create them? During
upgrade the system-vms did not upgrade so I did them manually and then the storage clean-up
script destroyed my systemVMs and I was stuck with a zone without systemVMs.
I could not do anything. Just imagine any of those above happen in production. Ouch.

I've tested 3.0.0-3.0.1-3.0.2 for about three months to get a complete picture and be able
to say I can put it in production. Testing for a couple of days would not suffice for me personally.
I've managed to squeeze the new 4.0 console proxy into the 3.0.2 environment so I'm very happy
now with it.
I think the only time I'm going to touch my environment when CS starts supporting windows
2012 and windows 8. Hopefully 4.1?

Personally I do not mind if a new feature is not 100% in newer releases however if a working
functionality breaks in the newer release I cannot live with that, this is the reason I'm
very picky.

This suggestion below is spot on. I can add, test your primary use cases vigorously for a
couple days. Then verify things like resources, make sure theyre inline with what cloudstack
is reportin, with the underlying infra(esp. storage) I've been using 4.0 without a hitch since
its release.

CentOS 6.3 + xenserver nfs and iscsi.
