#6533 obsolete Export appliance between CPU's supporting VT-x - settings cannot be changed will
Description

I exported a virtual machine as an appliance.

From: Vista 64 bit Q6600 cpu (with intel vt-x)

To: Ubuntu 64bit Q8200 cpu (without intel vt-x)

On the Ubuntu, it gave me a "no vt-x" error. Looking into the configuration files for the machine, it still had CPU count = "2" and "enabled" on the hardware virtualization settings even though the Q8200 doesn't support it. The problem was that on the Virtualbox, there were no options to disable the hardware acceleration options (it wasn't visible probably because it wasn't an option on that CPU type) - but it was enabled internally in the config files.

After modifying the .xml file, it worked fine!

#6534 obsolete Adding new virtual disk hungs virtualbox when previous location is inaccessible gorkem
Description

When trying to add a new virtual disk (vdi) either from virtual media manager or creating a new virtual drive (windows host),if "defaultHardDiskFolder" was set to an now inaccessible drive letter (e.g. a bootable harddrive with drive letter I:, which is now removed from system) virtualbox hungs.

To reproduce: 1- Open virtual box 2- make default machine an harddisk folder to an USB drive. 3- save and close virtual box 4- remove USB/removable drive 5- open virtual box 6- Try to add a new virtual drive 7- Observe virtual box is hung.

A typematic solution is :

Modify Systemproperties in configuration file

%USER_PROFILE%\.VirtualBox\VirtualBox.xml

e.g. if Systemroperties was:

<SystemProperties defaultMachineFolder="I:\vboxmachines" 
defaultHardDiskFolder="I:\vboxhd" defaultHardDiskFormat="VDI" 
remoteDisplayAuthLibrary="VRDPAuth" webServiceAuthLibrary="VRDPAuth" LogHistoryCount="3"/>

where drive letter I: is inaccessible change to an accessible drive (e.g. C:)

 <SystemProperties defaultMachineFolder="C:\" 
defaultHardDiskFolder="C:\" defaultHardDiskFormat="VDI"
 remoteDisplayAuthLibrary="VRDPAuth" webServiceAuthLibrary="VRDPAuth" LogHistoryCount="3"/>
