RHEL 6.3 VM loses network after Hyper-V live migration.

Solution Verified - Updated -

Issue

  • RHEL 6.3 VM loses network after Hyper-V live migration.

  • Live migration works from original host server to the second host node, with network connection losing three pings from an external host before being available. When migrating back to the original host, the network connection is lost until an outbound ping to the default gateway is sent from the RHEL VM.

Environment

  • Red Hat Enterprise Linux 6.3
  • Microsoft Server Enterprise 2008 R2
  • Hyper-V
  • Microsoft Linux Integration Services v3.4
