In one embodiment, a method receives a software upgrade package for a management computer and main computer. The management computer upgrades software of the management computer using the software upgrade package where the upgrading replaces an image of the software of the management computer with an image from the software upgrade package. Upon upgrade of the management computer, the management computer initiates an upgrade of the main computer. The main computer withdraws use of the services, and upon the withdrawing, the management computer reboots the main computer. Then, the main computer upgrades software of the main computer using the software upgrade package upon rebooting where the upgrading replaces an image of the software of the main computer with an image from the software upgrade package. Upon the upgrading, the main computer restores the use of the services.

Update management for a distributed computing system

In one embodiment, a method generates first entropy using a true random number generator in a management computer configured to manage a main computer in a computing device. The main computer controls a set of physical nodes including a set of services running in a set of virtual machines. The method then provides the first entropy to the main computer and the first entropy is combined with second entropy generated by the main computer to generate third entropy. The third entropy is provided to the set of physical nodes where the set of virtual machines access the third entropy via a hypervisor.
