Virtual machine live migration with seamless network connectivity

A computer program product for a virtual machine live migration, the computer program product comprising:

• a computer-readable storage media;
• first program code, stored on the computer-readable storage media, executable by a computer system to cause the computer system to create a port mirroring rule for a source virtual machine in a source computer such that ingress traffic received at the source computer for the source virtual machine is delivered to both the source virtual machine and a target virtual machine on a target computer, wherein the port mirroring rule is established prior to the virtual machine live migration;
• and
• second program code, stored on the computer-readable storage media, executable by a computer system to cause the computer system to migrate the source virtual machine on the source computer to the target virtual machine on the target computer in which the port mirroring rule directs the ingress traffic to both the source virtual machine and the target virtual machine while the source virtual machine is migrated from the source computer to the target virtual machine on the target computer during the virtual machine live migration.
