By default, the 'rewrite' profile is in APM portal mode. When enabling a 'rewrite' profile on a vCMP guest with ten cores allocated all layer 3 connectivity to the virtual IP will begin to fail.

When a 'rewrite' profile using the default settings is attached to a virtual server all layer 3 connectivity to the virtual IP will fail.


A 'rewrite' profile in portal mode (the default) on a vCMP guest with ten cores allocated. A 'rewrite' profile is required for rewriting content; this is required for APM Portal deployments and VDI deployments.


Use another core allocation configuration for the guest (such as two, four or eight). If the APM (portal) function is not required, create a custom 'rewrite' profile with the 'rewrite-mode' option of 'uri-translation'.
