Hello diegodlv,
Alas I suppose you won't get that 
because of the following:
You would get the Compatibility Matrix for ESXi versions vs Linux Versions. (that falls under VMware jurisdiction 
)
for OCFS2 vs Linux support ( you need to check at the respective sites)
Sharing VMDK disks using Multi-write flag has nothing to do with the above. You can do it to any VM irrespective of the installed guest OS.
So at this point I would suggest, go ahead and create shared disks using multi-write flag
Install the guest OS
Install and configure OCFS2 file system like you would do for any physical systems
Hope that helps
