Fix complaints about VT-x/AMD-V on CPUs lacking this feature #149

I'm also having that problem; I will try your patch, @glenux. |

It works well with WinXP, but there is still an issue at Windows 8 final boot (after setup). I'm not sure, but it seems that Microsoft has enabled Hyper-V and make the system still requires VT-x/AMD-V features after installation. i don't know how to test & disable it (if someone can help..). |

For me, WinXP wasn't booting but Win7 was (haven't tried Win8 as I have an actual installation of that on another partition). I found this suggestion worked, though I had to then tweak a setting like RAM allocation before it would recognize the change. The main problem is, although they boot now, all the XP VMs are the same, running IE6. I think there's something magic that happens when the ievms script runs that installs the different versions for you... can I trigger that to go again, now the VMs work? I did try running the bash script again, but it didn't do anything new. Update: heckit, I'm just going to download and run the installers manually in the VMs for IE7 and IE8. Will let you know how that goes. Update 2: works fine :) Now if it could just fix my IE8 bug in my website for me, that would be lovely. |

I've not looked at the IE8 issue but the reason you need to set CPUs to 1 is that VirtualBox requires VT-x/AMD-V for a guest to have more than 1 cpu. It would be better to not turn off the feature at all just set the cpus to 1. |

This patch fixes the issue for me :+1 . Setting CPU count to 1 was necessary, but doesn't hurt for my case (Windows XP anyways). |

This fix worked for me on an old laptop running Ubuntu. For OS X it seems that you can use sysctl such as described here: http://fortysomethinggeek.blogspot.com/2012/11/getting-cpu-info-from-command-line-in.html I don't have a Mac at the moment so I can't do it myself for now. |
"will will" should be just "will"
- remove the striked-through stuff - remove the reference to mondern.IE - add linkebreak for easy copy-pasting to curl-line
The previous change was not enough.
* Move the installation section up above the file-size-sections * Update markdown syntax so have better formatting
Detect CPU features and disable VT-x/AMD-V and related options on VM if needed.
Note: on machines lacking VT instructions, a strange complaint remains "VT-x is not available (VERR_VMX_NO_VMX)" if CPU number is not set to 1, so i forced it. (even on a machines with 4 cpus...)
