I was informed yesterday that due to corporate policy my workstation is to be re-imaged with Windows 10, and I will need to figure out how to save anything I want to keep. Simple docs are easy, of course, but I have 10 VBox guests, totaling a little over 600 gb. My intent is to test exporting/importing the vm's as appliances. To test, I did the following:
On my Win7 Pro 64-bit workstation, create a vbox guest running Win 7 Pro 64 bit
On the vbox guest, install Win 7 Pro 64-bit
On the vbox guest, install vbox 5.2.22
On the host, export one of my linux guests as an appliance
On the guest, import the appliance.
Everything went well and the appliance imported. However, when i tried to start the new vm (the guest of the guest), it threw "Error: VT-x is not available (VERR_VMX_NO_VMX)"
The machine properties for the Win7 guest show hardware virtualization, enable vt-x/AMD-V as enabled.
I will attach the vbox log from the startup of the win7 guest .. the guest that is itself the host of the second guest.
