Guru Meditation VERR_NET_IO_ERROR: Windows 2008 R2 during update request to WSUS => Fixed in SVN

[yesoos]

With latest virtualbox 4.2.0, my virtual Windows 2008 R2 machine hosting WSUS for other machines crashes when requested updates. This happens everytime. All machines use bridged networking, guest additions are at latest version.

Can you try to disable R0/GC for e1000 and reproduce the problem? To disable R0/GC use the following command lines:

VBoxManage setextradata <vm_name> VBoxInternal/Devices/e1000/<adapter_number_starting_with_0>/Config/GCEnabled 0
VBoxManage setextradata <vm_name> VBoxInternal/Devices/e1000/<adapter_number_starting_with_0>/Config/R0Enabled 0

Note that you will need to do it for each adapter used in VM. If later on you change the type of any adapter (to pcnet or virtio) you will get an error while starting VM. To get rid of it use the same commands as above but without '0' at the end of the line. After you disable RO/GC you may get a different error (not Guru Meditation). Please attach the resulting log file as well.

This is a confirmed 4.2 regression. The fix will be included into the next maintenance release. You can temporarily disable 'Large Send Offload' property in 'Advanced' tab of adapter properties in the guest to work around the problem.

The test build with the fix can be downloaded from ​here.

FYI, even with the stated workaround, Windows 2008 R2 guests still eventually crash with "Guru Meditation -400 (VERR_NET_IO_ERROR)" -- after moving ~55GB of data, in my case, and the server was running Exchange, not WSUS (although I first came across the issue on a WSUS guest). I mention this just in case the issue is bigger than it seems so far. Happy to provide further log files if needed.

EDIT: Host is Linux (Debian) running 4.2.0 (no hotfix available yet?)

​Here is a .deb package for Debian 6.0 / AMD64 and ​here is a 64-bit .run package as universal installer.

Fixed in 4.2.2.
