Abstract: Techniques for migrating virtual machines (VMs) in the presence of uncorrectable memory errors are provided. According to one set of embodiments, a source host hypervisor of a source host system can determine, for each guest memory page of a VM to be migrated from the source host system to a destination host system, whether the guest memory page is impacted by an uncorrectable memory error in a byte-addressable memory of the source host system. If the source host hypervisor determines that the guest memory page is impacted, the source host hypervisor can transmit a data packet to a destination host hypervisor of the destination host system that includes error metadata identifying the guest memory page as being corrupted. Alternatively, if the source host hypervisor determines that the guest memory page is not impacted, the source host hypervisor can attempt to read the guest memory page from the byte-addressable memory in a memory exception-safe manner.

Abstract: In various embodiments, a software program uses hardware features of a parallel processor to checkpoint a context associated with an execution of a software application on the parallel processor. The software program uses a preemption feature of the parallel processor to cause the parallel processor to stop executing instructions in accordance with the context. The software program then causes the parallel processor to collect state data associated with the context. After generating a checkpoint based on the state data, the software program causes the parallel processor to resume executing instructions in accordance with the context.

Abstract: Techniques for managing node failures in container environments are disclosed. In one example, a method determines when a first node executing at least one containerized workload has failed. In response to determining the first node has failed, the method marks a configuration object for the first node with an indicator that the first node is not to be used to schedule execution of a subsequent containerized workload, isolates from the first node one or more storage volumes used by the first node, and deletes configuration objects for the one or more storage volumes and for the containerized workload. The method then causes creation of a replacement containerized workload for execution on a second node, removes one or more artifacts associated with the containerized workload from the first node, and removes the indicator from the configuration object for the first node.
