this is the scenario
In order to use a raw disk as vmdk, need to start vbox as admin. Is this true? from my experience, this seems to be the case.
For other regular vms, can do it from UAC account.
Is it possible to open virtualbox.xml using lower privilege? so two vboxsvc.exe processes can modify it.

I'm not sure if this is a bug or feature. As you said, two VBoxSVC
daemons are running with different privileges. Why do you need to
start a VM as administrator at all? We don't recommend that for
security reasons.

A possible solution would be to use different XML settings by
specifying the VBOX_USER_HOME variable before starting a VBox
instance, see section 9.1 of the user manual.
