createrawvmdk seems broken in 3.2.6 => fixed in SVN

[dubuscyr]

Hi all,

I'm reporting this because I think this is a bug. At least, I can reproduce it.

I'm trying to use a USB Key (physical) as a virtual disk for a VM. For this, I looked at the documentation, and I found something at 9.7.1.1 :

VBoxManage internalcommands createrawvmdk -filename /path/to/file.vmdk -rawdisk /dev/sda

I apply this to my case, the command runs well. But when I start my VM with this vmdk disk, I got exactly the same error as Beren in this topic :

The screenshot is available here : ​http://www.joelandmeg.com/webpics/win7shot.png

I tried to downgrade Vbox to the 3.0.8 version, and everything is working well.

That's why I think that the createrawvmdk command is broken in the last version.

I'm running MacOs X SL 10.6.4

The workaround is disabling the use of the new async I/O code... done by ticking "Use host I/O cache" for the SATA (and SCSI) controllers.

The fix will show up in 4.0.0_BETA4 and the next 3.2 maintenance release.
