Following our recent Open CLARC inception review of the Open HA Cluster (OHAC) agent for xVM Hypervisor guest domains, I thought a small 5 minute demo would be of interest.
Please hit the download key from the demo link to stream the demo, which can be found at the HA-xVM project page.
The demo is based on Solaris Express Community Edition build 86 and Solaris Cluster Express 2/08 simply to reflect the cheat sheet from the link above. The purpose of the demo was to show the following:
In particular, within the demo RG1 manages xVM domain domu1. RG1 is then switched from node podio2 to node podio1 and domu1 is subsequently live migrated between the two nodes. While RG1/domu1 is online on podio1 that node podio1 is crashed via "
uadmin 2 1". OHAC automatically detects that failure and restarts domu1 on podio2.
