Thanks all for your feedback.
I found an issue with the vm_tempalte configuration for systemvmtemplates. When
you've a fresh installation of CloudStack with VMware 5.5 or above, it uses the
guest_os_id 15 (which is Debian 32-bit) and it causes VMware to half-allocate
the configured default RAM of 256MB. In my test environments based on VMware
55u3 and 65u1, I found VRs to only get about 157MB RAM.
This is not an issue for non-rvr networks, but in case of rVR network (isolated
or VPCs), the redundant VR (specifically the master VR) would crash frequently
due to OOM triggered kernel panic. This issue could be fixed if you update the
guest_os_id for the VMware systemvmtemplate to id=99 (other64Linux, or
something newer like Debian7 64-bit or above). Due to backward compatibility
for VMware 5.0+, id=99 was used as newer OS are not supported on older vCenters.
With this fix and couple other optimization tricks (such as not rebooting on
patching and not rebooting again to reconfigure nics/macs and use udevadm), I
could get VMware to pass those rVR smoketests so there is no need to skip rVR
tests on Vmware now! With that said, this feature still may not be suitable for
production usage though.

Hi,
We are not running ACS but ACP, currently in version 4.7.11. We’d love to run
rVR on VMWare with ESXi, but as you pointed out it is currently not supported.
Regards
Daniel

No, not currently. We once had rVR but this is quite a while ago. We
migrated away but it was related to issues finally turned out not
related to rVR.
