Hi all,
     I'm trying Nested Virtualization feature on eMAG(ARMv8) platform,
could you please tell us the setup details in detail. Means how you guys
ran Nested Virtualization on ARM platform.
Also could you please tell us the kernel version and kernel source from any
git repo(mention kernel parameters if used any) and QEMU version and QEMU
source from git repo with parameters passed.

If you guys have any VM disks used to verify this feature, could you please
share those details as well. Share if any other details required

Appreciate your help, cooperation, and patience

*Regards*,
-Vishnu.

Hi Vishnu,

[ You already asked this question and received a reply off-list on
  Friday, but I'll repeat Marc's reply here on the list for the record.

  Also, I'm assuming you had difficulty with your e-mail and therefore
  sent from both your private and corporate e-mail client.  Please be
  careful about this in the future. ]

You need minimum an Armv8.3 CPU to run nested virtualization.

You can find patches including documentation and all the information you
need on the mailing list archives of both the kvmarm list and the
linux-arm-kernel list.

All you need is a suitable AArch64 file system, and you can create or
download whichever one you prefer and populate it with the tools you
need.

We (upstream Linux developers) are not in the business of supplying
binaries, file systems, distros or anything like that.

Please attempt to follow one of the numerous guides available online,
and if you have specific questions we will be happy to help.


Thanks,
