Amazon AWS enhanced networking compatibility issue

With this enhancement, there is a compatibility issue with older AWS VM versions. After downgrading a 6.2.1 image to an older version, network connectivity is lost. Since AWS does not provide console access, you cannot recover the downgraded image.

When downgrading from 6.2.1 to older versions, running the enhanced nic driver is not allowed. The following AWS instances are affected:

  • C3
  • C4
  • R3
  • I2
  • M4
  • D2
