How to change location path disk by default

[Izi92]

Dear All,

I try to change the location path using by default by Virtualbox using Vboxmanage.
When i create a VM with script, i would like set this location path "PCIROOT(0)#PCI(1F05)#ATA(C00T00L00)" but by default, i have disk "PCIROOT(0)#PCI(0101)#ATA(C00T00L00)"

Is it possible?

Thanks for your help !!

When someone hears/reads "default location path" they tend to think "default location path for VMs". That's not the problem in your case (the PCI part gave it away).

What is it that you want to do? In complete and full details please...

Hi socratis,

"Disk Location Path" is used by diskpart that's why i used this. Is based on the physical connection to the computer.


By default-->Location Path : PCIROOT(0)#PCI(0100)#ATA(C00T00L00)
My need -->Location Path : PCIROOT(0)#PCI(1F05)#ATA(C00T00L00)

Using Vboxmanage is it possible to change this ?

Please see the result of diskpart cmd

There is not a place somewhere that VirtualBox uses the PCI root devices. Unless you're talking about raw access. So, I'm asking again:

What is it that you want to do? In complete and full details please...

ok

I want to set a custom Location Path:

I am using a script to a physical computer and in this script i am using the Location Path is PCIROOT(0)#PCI(1F05)#ATA(C00T00L00) to create partitions. It is the physical link between the motherboard and the physical disk drive.
When i install a VM with VB and i used diskpart to see by default the Location Path allows by VB is PCIROOT(0)#PCI(0100)#ATA(C00T00L00). It is the virtual link between the virtual motherboard and the virtual disk drive.
Before to modify all my scripts, i just knew if it is possible to modify PCI parameters.

If I read this correctly you don't want to change the disk location but the the disk controller location/address on the PCI bus.

Of course

location path is the term used by diskpart

Hi all,

I have changed the title to being more "clear"
There is a solution to change the virtual disk controller location/address on the PCI bus?

from PCIROOT(0)#PCI(0100)#ATA(C00T00L00)
to PCIROOT(0)#PCI(1F05)#ATA(C00T00L00)

[Izi92]

Hi,

When i install VM, by default, Vbox allow PCI address "PCIROOT(0)#PCI(0100)#ATA(C00T00L00)" to the system disk.
See the result with diskpart.exe

Using VboxManage.exe it is possible to change PCI values ?
-->from PCIROOT(0)#PCI(0100)#ATA(C00T00L00)
-->to PCIROOT(0)#PCI(1F05)#ATA(C00T00L00)

i found to the documentation
VBoxManage modifyvm --pciattach <host PCI address [@ guest PCI bus address] but i do not understand if i can used this feature.

Thanks for your help

No, you can't. That (experimental) feature is for pci passthrough and only available on linux hosts.
