Arm64

[anandkolli]

Hi,

I am trying run qemu-user-static:register on arm based machine (aarch64) and I am getting the below error please take a look
root@arm-ucpe-test:# uname -a
Linux arm-ucpe-test 4.10.0-38-generic #4216.04.1-Ubuntu SMP Tue Oct 10 16:33:57 UTC 2017 aarch64 aarch64 aarch64 GNU/Linux

root@arm-ucpe-test:~# docker run --rm --privileged multiarch/qemu-user-static:register
standard_init_linux.go:178: exec user process caused "no such file or directory"

So is this tested on aarch64?
Please let me know if you need more information.

Thanks,
Anand

I'm able to replicate the problem:

% uname -a
Linux ed-2a-bcc-llvm 4.10.0-38-generic #42~16.04.1-Ubuntu SMP Tue Oct 10 16:33:57 UTC 2017 aarch64 aarch64 aarch64 GNU/Linux

with this error message instead of yours

standard_init_linux.go:178: exec user process caused "exec format error"

And the reason for this is that the multiarch/qemu-user-static:register image is amd64 only:

root@ed-2a-bcc-llvm:~# docker run --rm mplatform/mquery multiarch/qemu-user-static:register
Image: multiarch/qemu-user-static:register
 * Manifest List: No
 * Supports: amd64/linux

Currently "multiarch/qemu-user-static" does not support aarch64 as a host architecture.
We needs to add new implementation for that. I am considering to add the feature. But not soon.
You can check this similar project: https://github.com/dbhi/qus

We created the unified ticket for this unsupported non-x86_64 host architecture here #77 . You can subscribe the ticket.
I like to close this ticket for the duplicated ticket.

But you can reopen this ticket, if you need it.
Thanks.
