Reading Time: 3 minutes One of the big news of the vSphere 8.0.3 (8.0 Update 3) version if the ability of live patch ESXi without reboot the host and without migrate the workloads! With the new Live Patching capability in ESXi, customers can address critical bugs in the virtual machine execution environment and apply patches to all components without reboot or VM evacuation. Virtual machines are Fast-Suspend-Resumed (FSR) as part of the host remediation process, for this reason this new feature is not compatible with some specific cases (like VM protected by vSphere FT or VM with PCI passthough).
