'VBoxManage debugvm guest_analysis osinfo' returns VERR_DBGF_OS_NOT_DETCTED

[rbarak]

When I execute VBoxManage debugvm guest_analysis osinfo, I get:

VBoxManage: error: DBGFR3OSQueryNameAndVersion failed with VERR_DBGF_OS_NOT_DETCTED
VBoxManage: error: Details: code VBOX_E_VM_ERROR (0x80bb0003), component MachineDebuggerWrap, interface IMachineDebugger, callee nsISupports
VBoxManage: error: Context: "GetOSName(bstrName.asOutParam())" at line 366 of file VBoxManageDebugVM.cpp

Is my command syntax invalid?

Doesn't seem to be wrong, according to https://www.virtualbox.org/manual/ch08. ... ge-debugvm

Googling "VERR_DBGF_OS_NOT_DETCTED site:forums.virtualbox.org" returns only your above post. So this one appears to be an 'un-forumed' error.

Looking in Introspection and guest debugging, I found that I cannot execute the VBoxManage debugvm osinfo on its own, but need first to execute VBoxManage debugvm osdetect (a bit unintuitive, but I guess the command's coder had good reasons not to execute internally the osdetect before executing the osinfo):

Code: Select all
