vmhgfs doesn't work with linux 3.13 kernel

Can you please provide logs, including dmesg, /etc/fstab, and other supporting evidence of this change?

The version of open-vm-tools-dkms is 2:9.4.0-1280544-5ubuntu2.
My fstab entry is:

The vmhgfs (VMWare Host<->Guest File System) module is no longer be supported by VMWare and it does not build on recent kernels. This merge proposal drops the vmhgfs module from the package. This eliminates the dkms package as ithis modules was the last out-of-tree module still being shipped. In removing the dkms package I am cleaning up the remaining man pages that referenced the kernel modules as well as a post-install script which had been updating the initramfs for the modules.

While this does remove the out-of-tree vmhgfs kernel module, it retains the fuse code for hgfs and the mount helper which are necessary for file drag-and-drop support in open-vm-tools-desktop.

I've unsubscribed the sponsors team since this was already sponsored.

This bug was fixed in the package open-vm-tools - 2:9.4.0-1280544-5ubuntu4

This solution is bullshit, all other distributions inkluding Debian ship a working version of the vmhgfs module. Debian unstable might need 3.16 to build, though, I've removed patches for older kernels.

"The vmhgfs (VMWare Host<->Guest File System) module is no longer be supported by VMWare and it does not build on recent kernels."

Robert, where did this information come from? According to Steve Goddard (VMware employee) in March 2014, "There has been a bug filed to track this issue and it will be addressed shortly." See https://communities.vmware.com/message/2355129#2355129
