ASUS R510D virtualization incompatibility.
Machine specifications support AMD-V.
System is stock:
- Windows 8 home upgraded to 8.1 home
- Quadcore 64-bit AMD A10-5750M APU
- Integrated dual AMD Radeon HD 8670M crossfire
"kernel panic - not syncing: Attempted to kill init!" on boot
The stack trace appears to descend into functions attempting to identify the 64-bit CPU model. Stack trace shows last function call is "identify_cpu".
I have tried every combination of virtualization and CPU settings in the VM settings. This includes:
Options for "Version" when "Type" is set to "Linux" in the VM settings "General -> Basic" tab
- Linux 2.2
- Linux 2.4
- Linux 2.6
- Other Linux
These options are each available in "32 bit" and "64 bit". When set to 32-bit and attempting to boot a 64-bit kernel, the kernel behaves as expected (ie error message about bitness).
- PS/2 Mouse
- USB Tablet
I/O APIC enabled/disabled
- EFI enabled/disabled
- Processor count from 1 through 4
- PAE/NX enabled/disabled
- VT-x/AMD-V enabled/disabled
- 2D Video Acceleration enabled/disabled
- Audio enabled/disabled
- Network adapter enabled/disabled
USB controller disabled / 1.0 / 2.0 / 3.0
Each of the last two or three stable VirtualBox versions (as of the time of this writing) and the next beta (as of the time of this writing)
The VirtualBox beta includes extra options for virtualization interface, such as "none", "legacy", "default", "minimal", etc. Combinations including each of these options were tried as well.
Removing all possible peripherals. It's a laptop so there's not much to remove but I made sure there weren't any disks in the drives or USB devices attached.
- Bodhi Linux (variant of Mint) 64-bit VM
- All non-working distros mentioned above when run on Windows 7 on Intel Core2 Duo or Quadcore i7 laptop
- Current 64-bit Minimal Linux Live ISO (which uses an up-to-date kernel as of February 2015) (http://minimal.linux-bg.org/)
- and more
The Minimal Linux Live ISO DID boot successfully at least once. I have no idea what I did that got it to boot or subsequently prevented it from booting. Update note: I'm starting to think I must have been mistaken.
The ASUS laptop does not have any virtualization settings available in the BIOS settings.
I have read forums that indicate that there is a problem with Realtek wireless drivers and that disabling the onboard wireless in host BIOS prevents the VM kernel panic, but this BIOS has no options for disabling internal wireless. I have not found any direct solutions but a high percentage of issues seem to involve ASUS boards from the last 5 years.
- Include links to referenced posts containing relevant information
- Include VirtualBox logs and screenshot of kernel panic
- Test same distros on other virtualization clients (any suggestions?)
- Test same distros on Linux hosts (I'm pretty sure most of them work on Intel hardware)

I have attached the VirtualBox log and screenshots on my post on the VirtualBox forums. I have also found VMware Player does not have these problems. It's possible that there is still some problem with the same bug in VMware, but in VMware it doesn't stop the system from booting and running fine. I haven't gone over all of the system log and boot logging.
For now, I am content with using the noncommercial VMware in place of VirtualBox. I have been an advocate of VirtualBox but this is a clear difference in product. I may not be able to continue using VMware depending on my licensing needs, but I may not be able to continue using VirtualBox depending on my requirements. I am curious if the bug is in the kernel, VirtualBox, or something else. Perhaps QEMU or KVM would be viable.
So my actual question as stands is:
-Why didn't some 64-bit kernels work in VirtualBox on this machine?
-If it's a problem in VirtualBox, why did some distros work while others did not?
-What can be done to get the kernel to run in VirtualBox, or why can't it be done?
-Are there still related problems in VMware?
Below are results of running virtualization detection on my hardware:
