AHV Virtualization

Hello everyone, Does anyone have an official date for the support of vSphere 5.5? And with 5.5 update 1 right around the corner (next month or so), do you now if the U1 version will be supported on the release date or will we need to wait some more? For what it's worth, our block is running fine in 5.5 since ~1month (although unsupported by Nutanix, we updated it with VUM without problem). Thanks in advance for you answers, Sylvain.

Can someone enlighten me, why KVM uses iSCSI-LUNs and not the NFS exported container like it is done with vSphere/ESX? Currently, I only see disadvantages, like cumbersome handling of VMs, and no benefits.
