Raw vmdk does not work with SATA -> fixed in 2.0.4

[vkov_tinsky]

Trying to start a VM with a raw vmdk attached in SATA mode results in the following error:

Unknown error creating VM.
VBox status code: -2 (VERR_INVALID_PARAMETER).

Result Code: 
NS_ERROR_FAILURE (0x80004005)
Component: 
Console
Interface: 
IConsole {d5a1cbda-f5d7-4824-9afe-d640c94c7dcf}

• Attaching the raw vmdk using IDE works fine
  

• Reproduced on hosts: Windows, Linux (Ubuntu 8.04, i686, kernel 2.6.24-21)
  

• Problem not present on VirtualBox v1.6.6 (using same vmdk)

Log for raw vmdk + SATA problem

Log for SATA problem on VirtualBox 2.0.0 and 2.0.2

[Jim Turnbull]

I have the same problem on VirtualBox 2.0.2 (happened to me on 2.0.0 as well). Running Vista x64 Host and Windows XP Pro (32-bit) Guest. Error occurs almost straight away before the VB BIOS screen appears. The disk image boots okay when switched to IDE mode.

[seraphim]

the bug still exists in 2.0.2 with debian etch kernel 2.6.18-6-686 host and windows guest.

Thanks for reporting it. Just fixed it locally. Unfortunately you'll have to wait for the next version.

Is there an ETA on 2.0.4? :O

[vkov_tinsky]

Raw vmdk + SATA still does not work:
Booting a WinXP SP2 (32-bit) guest with v2.0.4 (on both WinXP & Ubuntu 8.04 hosts) results in a crash (in vboxdd). Again, the issue does not appear when using IDE.

Can you provide a core dump please? This is described here ​http://www.virtualbox.org/wiki/Core_dump Please compress and make it available for download somewhere like for example ​http://www.2shared.com or ​http://www.rapidshare.com

Thank you.

[aeichner]

No need to create a core dump I was able to reproduce it. Can you try if the following command works around the crash: VBoxManage setextradata <VM name> VBoxInternal/Devices/ahci/0/Config/UseAsyncInterfaceIfAvailable 0

I'm really sorry for any inconveniences.

[vkov_tinsky]

Setting UseAsyncInterfaceIfAvailable 0 does indeed stop the crash and the VM boots normally with SATA enabled. (I've only had time to test this with XP host+guest for now.)

[vkov_tinsky]

Setting UseAsyncInterfaceIfAvailable=0 on Linux host (Xubuntu 8.04 32-bit) cures the crash also.

[vkov_tinsky]

Sorry, forgot to ask: Does setting UseAsyncInterfaceIfAvailable=0 reduce performance and does it only affect SATA? (Theoretical question of course since VM boot isn't possible otherwise.)

Regards, VT

[aeichner]

Yes only SATA is affected. Performance shouldn't be affected.

[vkov_tinsky]

Apologies in advance since this is slightly off-topic: I get worse performance with SATA than IDE under WinXP host (see ​http://forums.virtualbox.org/viewtopic.php?p=43470#43470). As far as I'm aware there's nothing wrong with my host XP installation so my question is whether a) This is normal or b) I should report this.

[Frank Mehnert]

Please check version 2.0.6. The bugs should be fixed and the SATA performance should be improved.
