METHOD AND SYSTEM FOR MAINTAINING DIRECT HARDWARE ACCESS IN THE EVENT OF NETWORK INTERFACE CARD FAILURE |
摘要 |
A system for maintaining direct hardware access in the event of PNIC failure. A host for the system includes: a processor; a first and a second PNIC, where the first PNIC is activated and all other PNICs are deactivated; a host operating system; a virtual machine; and a hypervisor for transferring packets between the host operating system and the virtual machine. The host operating system includes a link aggregator, multiple host VNICs, and a virtual switch associated with the VNICs. The first virtual machine includes a virtual network protocol stack and a guest VNIC. The link aggregator is configured to determine whether the first PNIC has failed. Based on a determination that the first PNIC has failed, the link aggregator is further configured to: remove a virtual function mapping between the first PNIC and the virtual machine; determine the second PNIC; deactivate the first PNIC; and activate the second PNIC.
