Virtual machine migration to sr-iov capable hypervisors

A computing apparatus comprising:

• a memory;
• and
• a processing device, operatively coupled to the memory, to execute a virtualization manager to:
• receive a request to migrate a virtual machine from a source hypervisor to a destination hypervisor;
• responsive to determining that an availability status indicates that a virtual function is available for use on the destination hypervisor by the virtual machine, migrate, by the virtualization manager, the virtual machine from the source hypervisor to the destination hypervisor;
• and
• responsive to determining that the virtual machine has been migrated to the destination hypervisor successfully, connect, by the virtualization manager, the virtual function to the virtual machine.

A non-transitory computer readable storage medium, having instructions stored therein, which when executed by a processing device of a computer system, cause the processing device to:

• receive, by the processing device executing a virtualization manager, a request to migrate a virtual machine from a source hypervisor to a destination hypervisor;
• identify a logical network associated with the virtual machine on the source hypervisor;
• identifying a virtual function associated with the logical network on the destination hypervisor in view of an availability status that indicates whether the virtual function is available for use;
• responsive to determining that the availability status indicates that the virtual function is available for use on the destination hypervisor, migrate, by the processing device executing the virtualization manager, the virtual machine from the source hypervisor to the destination hypervisor;
• modify the availability status to indicate that the virtual function is not available;
• create a temporary virtual network associated with the identified logical network on the destination hypervisor;
• and
• responsive to determining that the virtual machine has been migrated to the destination hypervisor successfully, connect, by the processing device executing the virtualization manager, the identified virtual function to the virtual machine.
