Shared folders do not work under guest Arch Linux Kernel 3.11 => Fixed in SVN

[HughYoung]

Shared folders in my Arch Linux VMs stop working once I upgrade to linux kernel 3.11. This is a silent failure, at the moment I can't get many diagnostics as to what's going on. I can mount the shared folder just fine, the problem is when I try to access it - any process which tries to read the volume hangs indefinitely. This includes ls.

I am aware that similar bugs have been posted about the status of guest additions in kernel 3.11 but I have yet to see any outline of this specific problem. Pardon me if this is already being addressed somewhere else.

I am using a Mac OS X 10.8.5 (Mountain Lion) host.

I can add that this problem also exists on fedora with 3.11 kernel.

In all my searches on this all point to the problem none to a solution.

Issue seems to exist on kernel versions 3.11, regardless of the used host OS or Linux distribution running in the guest. I can reproduce the issue when running Arch Linux with the kernel 3.11 and Windows 7 as the host OS. For more reports, see :

Thanks for the report. The fix for the code in 4.2.18 can be found in r48529.

And also fixed in 4.3.
