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

[Austin English]

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?

[Austin English]

vbox.log

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?

[Austin English]

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.
