Fedora 19 on Windows 7; shared folder access hang

Posted: 23. Sep 2013, 02:33
by ambarish
VirtualBox version: 4.2.18 r88780
Host: Win7x64 SP1
Guest: Fedora 19 (Linux 3.11.1-200)

I've shared a folder from the host and am trying to read it within the guest. Unfortunately, any access hangs at getdents64(2); see screencast below. Should I file a bug? What logs would be useful in figuring out what's going on?

Known issue with the 3.11 kernel. Fix came out after 4.2.18, but is in 4.2.3 beta.

This is my first time in this forum and thank you all for all the tips. I'm learning a great deal about VB.

Looks like I have a related issue, though I'm running VirtualBox 4.3.4, host OSX 10.8.3, guest Linux Mint 16 with kenel 3.11 as well:

...
looks like a loop with 'getdents(6, /* 1 entries */, 32768) = 24' ad infinitum.

Any ideas? Did this fix not get in 4.3?
