1. A method comprising:
establishing, by a first switch processing circuitry of a first switch device, a first physical link between the first switch device and a second switch device, the first physical link connecting the first switch device to a plurality of virtual machines hosted by the second switch device;
monitoring, by the first switch device, the first physical link between the first switch device and the second switch device;
detecting, by the first switch device, that the plurality of virtual machines are not reachable via the first physical link;
responsive to the detecting, transmitting, by the first switch processing circuitry, a notification to a second switch processing circuitry of the second switch device, the notification indicating that the plurality of virtual machines are not reachable via the first physical link; and
responsive to the transmitting, re-connecting, by the first switch device, to the plurality of virtual machines hosted by the second switch device via a second physical link that differs from the first physical link.
