  • 1.  High Availability for a virtual machine

    Posted Mar 31, 2021 01:14 PM

    Hi,

    I am aware of ESXi node failover / HA during a  ESXi node failure.

    Does VMware provide fault tolerance / HA for failure of a single VM, not the entire host.

    Thank you.

    Yes, it is called, surprise surprise, vSphere Fault Tolerance aka FT. it provides a live shadow copy of the VM, and this VM will run on a second host, allowing FT to failover when something happens to the host or the VM process.

    Note, this does not help with failures within the VM. That is what vSphere HA VM Monitoring is for. That would allow you to restart a VM in the case of a guest operating system failure for instance

    There's a bunch of requirements in order to enable FT on a VM (or VMs). This should help guide you:
