I'm running VMWare ESXi 5.1 as a host.
Within that host I have several virtual machines running:
I also have a HTPC which boots the xbmcbuntu iso, using TFTP, from NiY and mounts an additional NFS share for copy on write.
And downloadserver mounts a NFS share from NiY
My problem is that since i upgraded downloadserver from Ubuntu 12 to Ubuntu 14, it can no longer mount the NFS shares from NiY. The HTPC still can mount all the NFS shares.
What I have tried so far:
The last line keeps appearing in the logs
/etc/exports:
I tried mounting with verbose logging and running Wireshark to check if anything did go to NiY (either by hostname or ip address):
And it just hangs until i press [CTRL] + [C]
This is the output from Wireshark running on NiY with the previous mount command (only showing traffic from and to downloadstation)
Any help?
Within that host I have several virtual machines running:
- **NiY** My main server (CentOS release 5.10 (Final))
- **downloadstation** My download server (Ubuntu 14.04.1 LTS)
- And several other which are not important

What I have tried so far:
- Pinging all machines from all machines by hostname and IP, this works
- Granting all access in /etc/exports
- Disabling iptables on NiY (downloadserver is not running iptables)
- Using showmount to inspect the exports from NiY, this works: http://pug205.nl/stackoverflow/showmount.jpg
- Mounting the nfs share on NiY, this works
- Installing a fresh virtual machine with Ubuntu 12 and mount, does **not** work
- Installing a fresh virtual machine with CentOS 7 and mount, does **not** work
- Mount my NAS via NFS, this **does** work from **all** machines
- Checking logs on NiY, they are not mentioning any thing related to NFS
- logs on downloadstation contain some information
