I am running v5.1.26r117224 under Ubuntu Linux 16.04.3 (headless) using x86_64 architecture.
The kernel is stock: v4.4.0-93-generic.
This is what I have done:
1. I have create two subsequent snapshots for the same machine (on the main host).
2. I have copied the whole folder to the secondary machine.
3. I have stopped the VM on the main host.
4. I have deleted the second snapshot (on the secondary host).
5. I have restored the first snapshot (on the secondary host).
6. I have restarted the VM (on the secondary host).
I have got this error message:
Error: failed to start machine. Error message: Failed to load unit 'cpum' (VERR_INVALID_FLAGS)I suspect that there can be a problem with the CPUs of the two hosts (main and secondary).
In particular I have:
MAIN processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 63 model name : Intel(R) Xeon(R) CPU E5-2620 v3 @ 2.40GHz stepping : 2and
SECONDARY processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 45 model name : Intel(R) Xeon(R) CPU E5-2407 0 @ 2.20GHz stepping : 7Despite there's no documentation, I have then tried to use the a "vboxmanage modify" command to set "--cpuid-portability-level".
I have got another error message:
~ vboxmanage modifyvm na1 --cpuid-portability-level 1 VBoxManage: error: The machine is not mutable (state is Saved) VBoxManage: error: Details: code VBOX_E_INVALID_VM_STATE (0x80bb0002), component SessionMachine, interface IMachine, callee nsISupports VBoxManage: error: Context: "COMSETTER(CPUIDPortabilityLevel)(ValueUnion.u32)" at line 657 of file VBoxManageModifyVM.cppAny hint on how to solve the problem (provided that's possible)?
TALIA.
