Finding support information is a minefield... After about 30 minutes of searching, I found the following in the VVR admin guide:
http://sfdoccentral.symantec.com/sf/5.0MP3/linux/pdf/vvr_admin.pdf
p. 20:
Supports cross-platform replication, that is, the Primary and Secondary can have different operating systems.
Supported Linux versions are listed in the Release Notes:

p.26 & 27:

(x86_64)
■ SUSE Linux Enterprise Server 10 (SLES 10) with SP1 (2.6.16.46-0.12 kernel or

If your system is running an older version of either Red Hat Enterprise Linux, SUSE Linux Enterprise Server, or Oracle Enterprise Linux, you must upgrade it before attempting to install the Veritas Storage Foundation software. Consult the Red Hat, SUSE, or Oracle documentation for more information on upgrading or reinstalling your system.
Symantec supports only Oracle, Red Hat, and SUSE distributed kernel binaries.
Symantec products operate on subsequent kernel and patch releases provided the operating systems maintain kernel ABI (application binary interface) compatibility.
Information about the latest supported Red Hat erratas and updates and SUSE service packs is available in the following TechNote. Read this TechNote before you install Symantec products.
