CHAPTER 5

General Upgrade Notes

5.1 Job timeouts are shorter than before

Please be aware that in 4.5 a bug is ﬁxed (CLOUDSTACK-7595) that makes sure global settings

‘job.cancel.threshold.minutes’ and ‘job.expire.minutes’ are deﬁned in minutes as they are supposed to be. Before,

they were accidentally 60x bigger than conﬁgured. This means previous versions had a much higher timeout. You

might hit this timeout when migrating large disks or making big snapshots, etc.

5.2 Java version upgraded to Java 1.7

As of Apache CloudStack 4.4, Java version required is 1.7 for the management-server, cloudstack-usage, KVM agent

and system-VMs.

5.3 Depreciation of realhostip.com

The realhostip.com dynamic DNS resolution service is being retired on September 30th, 2014. In advance of that,

CloudStack 4.3 and later no longer uses realhostip.com DNS domains or SSL certiﬁcates to encrypt Console Proxy or

ﬁle copy communications.

For latest update about realhostip.com follow Apache CloudStack Blog.

5.4 Settings Changes

After upgrading to 4.2 and later, Settings mem.overporvisioning.factor and

cpu.overporvisioning.factor are now at the cluster level and be set to 1 which is the default.

If Global Settings mem.overporvisioning.factor and cpu.overporvisioning.factor have been

changed prior the upgrade to 4.2 and later, the upgrade process will be reset them to 1. Values can be changed by

editing clusters settings.

All clusters created after the upgrade will get created with the Global Settings values for

mem.overporvisioning.factor and cpu.overporvisioning.factor.
