vMotion between hosts using the vMotion netstack and hosts on a different subnet fails with "The vMotion failed because the destination host did not receive data from the source host on the vMotion network."

Products

• VMware vSphere ESXi
• VMware vCenter Server

Issue/Introduction

• vMotion between hosts on different vMotion subnets fails with "The vMotion failed because the destination host did not receive data from the source host on the vMotion network."
• At least one of the hosts is using the vMotion netstack.
• The vMotion vmkernel adapter has a gateway set using the "Override default gateway" option
• No default gateway is configured on the vMotion netstack

Environment

VMware ESXi

Cause

In order for a default route to exist on a vmkernel adapter on a non-default netstack the Default Gateway must be set on the netstack through the vCenter UI or by setting a static route at the ESXi CLI of the host.

Resolution

Configure the Default Gateway on the vMotion netstack following Cross vCenter vMotion failed with error: "Destination host did not receive data from the source host on the vMotion network"
