Description: The total amount of available memory in Kbytes on the physical host.
What is xenHostTotalMemKBytes?
This value reports the total amount of memory, in kilobytes, available on the physical host running Xen. An admin compares it against the sum of xenDomainMemKBytes across all domains to gauge how much host memory remains available for new or growing virtual machines. For example, an admin planning to launch a new VM would check xenHostTotalMemKBytes against current domain memory usage to confirm there's enough headroom.
Examples
