Abstract
A method, system and computer program product for providing filtering of level two guest (G2) quiesce requests. The method includes receiving a G2 quiesce interruption request at a processor currently or previously executing a G2 running under a level two hypervisor in a logical partition. The G2 includes a current zone and G2 virtual machine (VM) identifier. The quiesce interruption request specifies an initiating zone and an initiating G2 VM identifier. It is determined if the G2 quiesce interruption request can be filtered by the processor. The determining is responsive to the current G2 VM identifier, the current zone, the initiating zone and the initiating G2 VM identifier. The G2 quiesce interruption request is filtered at the processor in response to determining that the G2 quiesce interruption request can be filtered. Thus, filtering between G2 virtual machines running in the logical partition is provided.
