Abstract:
1. A method for migrating virtual machines, comprising: obtaining migration criteria for a first virtual machine (VM), sending a request comprising the migration criteria to a third blade in the blade chassis, receiving a response to request from the third blade, wherein response indicates that the third blade cannot satisfy the migration criteria; suspending the second virtual wire, wherein the first priority is higher than the second priority and wherein suspending the second virtual wire comprises suspending the third VNIC and fourth VNIC; suspending execution of the first VM on the first blade and obtaining information to migrate the first VM; obtaining information required to migrate the first VNIC; migrating the first VM and the first VNIC to the third blade using the information required to migrate the first VM and the information required to migrate the first VNIC; configuring the first VNIC and the first VM to satisfy the migration criteria; updating a virtual switching table in the blade chassis to reflect the migration of the first VM from the first blade to the third blade; and resuming execution of the first VM on the third blade.
