What values do you get if you enumerate ISystemProperties::mediumFormats <https://www.virtualbox.org/sdkref/interface_i_system_properties.html#a3fddf22466361f98b6dc9fc4458d1049> ?

If I used 'vmdk' instead of 'vdi' then it works. How is that possible, if using VBoxManage I can create VDI images? Do I have to pass a different set of parameters when using VDI? Or is a different type of image ( MediumVariant <https://www.virtualbox.org/sdkref/_virtual_box_8idl.html#adedcbf1a6e5e35fe7a0ca0c4b3447154> ) required when doing createBaseStorage() with the vdi format? Anyone got any pointers?

Can you simply confirm that self.vboxMgr.constants.MediumVariant_Standard is given in an array? (it looks like but not sure). Else, the size needs to be a long, if such type exists in Python.

I can successully create the IMedium object using IVirtualBox::createHardDisk() but then when I try to call createBaseStorage() on that object, I can an error saying "Error in module Medium (VERR_INVALID_PARAMETER)" but I do not get any further details on what the problem is. According to the SDK documentation, the only error for this function should be if the medium format is not supported by my system ("The variant of storage creation operation is not supported."), but I am just trying to create a VDI disk, and when I list the HDD backends using VBoxManage, it is definitely supported. The path I'm trying to create the virtual disk under is also accessible and writable. What else can the problem be? I do not seem to be able to dig deeper into this. I'm using the MediumVariant_Standard variant, so there is nothing special about this either. Any pointers would be really appreciated. _______________________________________________ vbox-dev mailing list vbox-dev@virtualbox.org <mailto:vbox-dev@virtualbox.org> https://www.virtualbox.org/mailman/listinfo/vbox-dev
