Measures reported by OVMGuestStatusTest
Live migration is a process to move a running virtual machine from one Oracle VM Server to another, while applications on the existing virtual machine continue to run. Because of live migration, administrators often struggle to determine which VM was migrated between which two Oracle VM servers. This is where the OVMGuestStatusTest test helps.
This test enables administrators to determine how many guests have registered with the Oracle VM server, and how many of these are currently running. In addition, the test also indicates whether any guests have migrated to or from the virtual server.
The measures made by this test are as follows:
