I recently downloaded a VPS server image and got it working on my mac under virtualbox. However, I've now copied the ova export to my linux server and I can't seem to get it to boot on that - I keep getting the following error:

root@billy:~/VirtualBox VMs/Helium# VBoxManage startvm Helium --type headless
Waiting for VM "Helium" to power on...
VBoxManage: error: VT-x features locked or unavailable in MSR. (VERR_VMX_MSR_LOCKED_OR_DISABLED)
VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component Console, interface IConsole, callee

The machine I've moved it to doesn't support VT-x (or it's not enabled in the bios.. but that's because the motherboard battery is dead..replacement on the way - another story entirely). However, I've disabled all the VT-x stuff using VBoxManage and I'm still getting the error.

I've attached my XML config for the server - if anyone has any suggestions I'd really appreciate it. Thanks!

Host Virtualbox is: 4.1.18_Debian

Host CPU info: Pentium(R) Dual-Core  CPU      E5300  @ 2.60GHz

The VM was registered with 2 CPUs.. this caused the VTx error message. I'm not quite sure why that's something to do with VT-x, I suppose multi-cpu virtualisation probably is a VT-x instruction or something.

So you must make sure your VM only has one cpu if you're getting this error in addition to disabling the other vt-x bits.
