1. A method for error monitoring of a plurality of partitions in a computer system, each partition having its own operating system, said computer system comprising a hypervisor that mediates between or among said operating systems, said method comprising executing a computer readable program code stored on at least one computer usable medium of the computer system, said executing comprising: providing a global supervisor mapping (GSM) that associates each partition with a supervisor partition selected from the plurality of partitions in a one-to-one mapping; providing a partition status buffer (PSB) for each partition of the plurality of partitions, said partition status buffer denoting a status of the partition, said status being selected from a group of statuses that comprises a BAD status and a NOCARE status, said BAD denoting that the partition has encountered at least one error that is currently unrepaired; determining, by a first supervisor partition of the supervisor partitions, the partition that is associated with the first supervisor partition in the global supervisor mapping, said partition associated with the first supervisor partition being denoted as a supervised partition; ascertaining, from the partition status buffer, the status of the supervised partition; if said ascertaining ascertains that the status of the supervised partition is not the BAD status then exiting from the method, else performing a recovery procedure comprising: obtaining by the first supervisor partition a grant of access to physical and logical resources of the supervised partition; gathering by the first supervisor partition error data relating to the supervised partition, said gathering being from said physical and logical resources of the supervised partition; and setting the status of the supervised partition to the NOCARE status in the partition status buffer.
