VirtualBox hangs when copying a large directory in debian testing when 3.0.0-1 kernel

Description (last modified by frank) (diff)

Regression from linux-image-2.6.32-5-686. I wanted to copy a directory (the wine git repository). Doing this with the 3.0.0-1 kernel then causes VirtualBox to shutdown the virtual machine. If I do this with 2.6.32-5, the directory copies without problems. Command used was: $ cp -r wine-git wine-clang

VirtualBox version is 4.1.0, r73009. Host is Ubuntu 10.04.3, 32-bit.

  1. Please check if the same happens with VBox 4.1.2
  2. If so, please provide a VBox.log file of such a VM session
  3. What kind of folder was it where you tried to copy? Was it a local (virtual) disk, a network folder or a VBox shared folder?

  1. With 4.1.2, the VM hangs, but does not give the shutdown dialog.
  2. Attached.
  3. Copying from a local virtual disk to the same local virtual disk.

Hmm, your host kernel is obviously PAE-enabled and your guest has 2GB RAM. I assume your guest kernel is also PAE-enabled, is that right? Any difference if you disable PAE for that guest? Any difference if you disable nested paging for that guest?

Guest is pae enabled, yes. Refuses to boot the kernel if I disable pae.

With nested paging disabled, the copy succeeds.

Thanks for the test! This is a known bug (32-bit hosts + PAE guests + nested paging). You could install a non-PAE guest kernel, this should work as well with nested paging enabled.
