Couple of things to check. |
| 23 |
|
| 24 |
1. Make sure you've turned on all the related BIOS features that may be |
| 25 |
related. Sometimes it's more than one or two depending on the manufacturer. |
| 26 |
|
| 27 |
2. Verify that your chip supports 64bit VT. I found out recently that my |
| 28 |
Intel T6600 while 64bit can only run 32bit guests. |
| 29 |
|
| 30 |
3. You're running vbox 3.1.8 which is stable for x86 while vbox 3.2.12 |
| 31 |
is stable for amd64. Is your host OS 32bit? |
