P r o m e t h e u s

• Provide ease in connector configuration using
CloudStack global settings
• Perform SSO from CloudStack UI into Cloudian
Management Console (CMC) when the connector is
enabled
• Auto provisioning and de-provisioning of CloudStack accounts and domains
as Cloudian users and groups respectively
• During CloudStack UI logout, logout user from CMC
• CloudStack account will be mapped to Cloudian Users, and CloudStack
domain will be mapped to Cloudian Groups

CloudStack InternalsCloudStack Internals

• Host-HA framework and HA-provider for KVM hosts with and NFS as
primary storage, and a new background polling task manager.
• Secure agents communication: new certificate authority framework
and a default built-in root CA provider.
• Separation of volume snapshot creation on primary storage and
backing operation on secondary storage.
• Embedded Jetty and improved CloudStack management server
configuration.
C l o u d S t a c k I n t e r n a l s

• Improved support for Java 8 for building artefacts/modules,
packaging, and in the systemvm template.
• A faster console proxy start-up and service availability.
• A new Debian 9 based systemvm template that patches systemvm
without requiring reboot.
C l o u d S t a c k I n t e r n a l s

Without Host HA
• When the connection to a CloudStack KVM host agent is lost,
this could be due to:
• Host agent crash
• Management network issue
• Host crash
• Which situation we are in cannot be determined
• Guest VMs may still be running. Split brain is VERY BAD™
- so do nothing…
H o s t H A

With Host HA
• Use other hosts in the cluster to poll shared storage.
• If no disk activity seen from VMs on the suspect host, then
reboot host (via IPMI)
• If still no connection from agent and no disk activity from VMs,
then power off host (via IPMI) and trigger VM HA
• All timeouts and checks are configurable.
H o s t H A

H o s t H A

• Framework to store and use SSL
certificates with CloudStack’s reach.
• CloudStack can act as a CA and
create/revoke certificates
• Implemented in host <-> mgmt. server
communications and upcoming TLS KVM
migration work
