#12452 closed defect (wontfix)

The linux-64bit vm created by VBoxManage lost longmode on option

Reported by: feverwind Owned by:
Component: VM control Version: VirtualBox 4.3.4
Keywords: VBoxManage Cc: Frank
Guest type: Linux Host type: Windows


Sorry to frank, on ticket 12443, I give a wrong create bat.

Now I think I found the bug, if I use the VBoxManage to create linux2.6-64bit vm, it lost longmode option, and if I use Virtualbox GUI create a same configure linux2.6-64bit vm, it have the longmode option.

So I think I found the bug, use VBoxManage to specify ostype Linux26_64,it doesn't add longmode option automatically.

Below is my create bat:


VBoxManage createvm --groups /test --name test-device1 --register

VBoxManage modifyvm test-device1 --boot1 disk --boot2 none --boot3 none --boot4 none --ioapic on --rtcuseutc on --pae off --acpi off --cpuexecutioncap 80 --nestedpaging off --uart1 0x3F8 4 --uartmode1 file "C:\Users\jason\_mytest\project\test\device1.txt" --uart2 0x2F8 3 --uartmode2 server

I found that longmode is a new parameter.

I think you have the wrong expectations. The OS type of a VM is a hint for VBox how to choose certain defaults while the VM is created. If you change the OS type later (when the VM does already exist), only the OS type is changed and the corresponding icon. The reason for this restriction is to prevent side effects by changing the OS type. Consider that a user created a VM, changed a lot of settings manually (as you do) and then changes the OS type. This would again change a number of VM settings which is not obvious to the user.

Therefore you have to use --longmode on to allow 64-bit guests when the VM is already created. Or use the --ostype option when you create the VM, i.e.

VBoxManage createvm --groups /test --name test-device1 --register --ostype Linux26_64

I don't see the --ostype parameter when you create a VM nor I see the --longmode option when you modify the VM settings of your VM.
