Re: [Xen-users] Android-PVH direct kernel booting

[Rajagopal Aravindan <a.rajagopal.81@xxxxxxxxx>]

Hello Kun,

Thanks for your reply.

>>Have you compelled android on x86 machine and tried to run it on a x86 platform too? In that case, you need android on x86 support.

Yes, I downloaded Android-x86 code and prepared iso_img.

I am able to natively install the iso_img and my x86_64 boots fine into Android-x86.  

Then, I tried installing from the iso_img in my Xen HVM guest, using a raw disk image file (loopback mounting).

This also works fine and I am able to boot my Xen HVM guest into Android-x86.

Now, I am trying to convert my HVM into a PVH guest and do direct kernel boot (dkb) by loopback mounting the raw disk image file.

Which is when I am running into ""Detecting Android x86 ...".

PFA the dkb config file.

Any inputs would be very helpful.

>>If you are cross compelling android, then you need to check your toolchain. Also I am not sure if you can run arm guest domain on a x86 platform.

Once I meet with success on x86, would be trying this next.

Thanks,

Rajagopal

Hello Rajagopal,

Some quick thoughts.

1. Have you compelled android on x86 machine and tried to run it on a x86 platform too? In that case, you need android on x86 support.

2. If you are cross compelling android, then you need to check your toolchain. Also I am not sure if you can run arm guest domain on a x86 platform.

Hello Denis & Kun,

Any thoughts on the below mail, please ?

Once I get Android to direct kernel boot as Dom-U on x86, I  shall try the same on OdroidXU4.

Thanks in  advance,

Rajagopal

Hello Xen,

I built an Android ISO with PVH enabled and installed it in HVM mode.

Now, I am trying to convert it into a PVH using direct kernel booting.

But, while attempting to boot, booting gets stuck at "Detecting Android x86 ......."

PFA my config file.

Can someone please point me in the right direction, for getting this to work ?

Using the above method I am able to boot into Ubuntu, though.

Thanks,

Rajagopal
