VMCL is the first free high availability software for VMware
environment, It's based on famous
Linux-HA cluster software.
It manages virtual machines failover when a physical host crashes
VMCL has a feature actually not available in any other commercial
product: it decides which available physical host has to start faulty
virtual machines depending on specific parameters (free memory, CPU
usage) to be respected and considering a defined priority.
The whole thing is based on a quorum disk (a VMDK formatted ext3)
created for every physical host, where every virtual machine
configuration file (.vmx) is copied and synchronized.
When a physical host is faulty VMCL will decide which remained
physical host has to mount faulted host quorum and to start which
virtual machine. Documentation
coming soon For heartbeat documentation refer to web site
