    Amazon AWS enhanced networking compatibility issue

    Amazon AWS enhanced networking compatibility issue

    With this enhancement, there is a compatibility issue with 5.6.2 and older AWS VM versions. After downgrading a 6.4.1 image to a 5.6.2 or older version, network connectivity is lost. Since AWS does not provide console access, you cannot recover the downgraded image.

    When downgrading from 6.4.1 to 5.6.2 or older versions, running the enhanced NIC driver is not allowed. The following AWS instances are affected:

    C5

    C5d

    C5n

    F1

    G3

    G4

    H1

    I3

    I3en

    Inf1

    m4.16xlarge

    M5

    M5a

    M5ad

    M5d

    M5dn

    M5n

    P2

    P3

    R4

    R5

    R5a

    R5ad

    R5d

    R5dn

    R5n

    T3

    T3a

    u-6tb1.metal

    u-9tb1.metal

    u-12tb1.metal

    u-18tb1.metal

    u-24tb1.metal

    X1

    X1e

    z1d

    A workaround is to stop the instance, change the type to a non-ENA driver NIC type, and continue with downgrading.
