Abstract: Examples provided herein describe a system and method for migrating virtual machines. For example, a target hypervisor of a target device may determine whether bandwidth exists on the target device to migrate a source set of virtual machines from a source device. The target hypervisor may determine whether bandwidth exists by: determining whether a source total amount of bandwidth is less than an available target total amount of bandwidth on the target set of host bus adaptors; and, responsive to determining that the source total amount of bandwidth is less than the available target total amount of bandwidth, moving a first target virtual host bus adaptor of the target set of virtual machines across the target set of host bus adaptors to make available the source total amount of bandwidth to migrate the source set of virtual machines. Responsive to determining that the source total amount of bandwidth exists, the source set of virtual machines may be migrated to the target device.

Abstract: Examples disclosed herein relate to virtual Fiber Channel port migration. In some examples disclosed herein, a failure in a primary physical host bus adapter (HBA) hosting a plurality of virtual HBA ports assigned to a virtual machine may be detected. In response to the detecting, incoming input/output (I/O) requests from the virtual machine may be placed into a wait queue, and the plurality of virtual HBA ports may be migrated to a backup physical HBA. After the plurality of virtual HBA ports have been migrated to the backup physical HBA, the I/O requests in the wait queue may be transferred to an active queue to be processed using the plurality of virtual HBA ports registered on the backup physical HBA.
