Virtual machine created on X computer does not work with Y computer

I created a virtual machine in an X notebook of Ubuntu 12.04, in which it worked normally. I created this machine so that I could use a Mysql database and move between two computers without having to reconfigure the database. However, when I turned on the virtual machine in notebook Y, this appeared:

Ooops.

I ignored the warning and started the machine. In notebook Y it is extremely slow and almost unusable, what does not happen in notebook X.

Notebook X features an Intel i5 (Sandy Bridge) with 6GB RAM and an Intel HD 3000. The notebook Y features an AMD Dual-Core E1-2500, 4GB RAM and an AMD Radeon HD 8248. Both run Windows 8.1.

Is it impossible for me to make the same virtual machine work on these two computers? Notebook Y is not capable of running virtual machines?

  • How many GB of RAM did you allocate to the virtual machine? Whether it was 2GB or more, it makes a big difference whether the host has 4 or 6GB...

  • @epx the virtual machine has the standard Vmware allocates pro Ubuntu, which is 1GB

I noticed the guest system (guest) is 64 bits. I’ve been through two similar situations because of this question.

First, make sure the two host systems (hosts) are 64 bits. There are some limitations when emulating a 64 OS over a 32 bit OS. Virtualbox, for example, does not even start the execution.

Second, make sure that the hardware is configured (BIOS) to support virtualization natively. On some boards, this is disabled by default. The option should be called VT (Virtualization Technology) or something similar. This link maybe help find the option. With the option disabled, Vmware will try to simulate virtualization via software, which is much slower.

If nothing else, it may be simply because of the stored state of the VM. It would be like you hibernate an OS, put the HD on another different PC and then turn it on. The hardware has changed, but the drivers remain the old ones. If you restart the same problem continues?

  • Yes, both hosts are 64 bits. But if it’s the BIOS issue, wouldn’t Vmware give a more specific warning? If that’s the case, I think it’s odd that you gave a vague warning like that.

  • @athosbr99 I don’t know in detail the error messages, but see that I added another paragraph to my reply. The problem may be simply because you switched hardware without turning off the image.

The Virtualbox (by Oracle) https://www.virtualbox.org/ works on MAC, Windows and Linux and you can use it with virtual machines created by Vmware. I successfully use Windows to open and run virtual machines created by Vmware on MAC OS X. Virtual Box is able to recognize the hard drive created on Vmware and boot normally. You must reconfigure in the Virtualbox of your Windows Notebook the network devices compatibilizando the environment, in addition to allocating the appropriate amount of memory.
