Description
Hello. Yes I've checked similar tickets.
I tried to setup a virtual machine with Ubuntu 12.04 x64 but it is not loading. It says:
This kernel requires an x86-64 CPU, but only detected an i686 CPU
I've already enabled VT-x feature in BIOS. I tried to boot it up with any combination of options for VM processor:
"Enable VT-x/AMD-V"
"Enable Nested Paging"
"Enable PAE/NX"
In VBox log I don't see any MSRs failures. Please take a look.
Host processor is Xeon E3-1275v3. Motherboard - ASUS Maximus VI Formula. Version of BIOS is latest available.
Attached log is collected with all options for processor is checked on.
Note:
See TracTickets
for help on using tickets.
You have to select a 64-bit OS type in your VM settings. If such OS types are not available, your host does either not support 64-bit guests or your host does not provide VT-x (or it is disabled). If you consider to reopen this ticket, please attach a VBox.log file (preferably taken from a VBox 4.3.8 session).
