Description Hu Zhang 2015-05-25 09:41:19 UTC 
Description of problem:
"file" fails to get the whole information of the new swap partition. It misses the label, UUID and some other info. This works well on x86.

Version-Release number of selected component (if applicable):
libguestfs-1.28.1-1.23.aa7a.aarch64
libguestfs-tools-c-1.28.1-1.23.aa7a.aarch64
kernel-3.19.0-0.75.aa7a.aarch64

How reproducible:
Always

Steps to Reproduce:
1. Create a new swap partition.
$ cd /tmp
$ truncate -s 1G swap
$ mkswap /tmp/swap
Setting up swapspace version 1, size = 1024 MiB (1073676288 bytes)
no label, UUID=b7ad4bd7-7a6b-47e9-b1fd-5ad0ea973d3c

2. get the swap info.
$ file /tmp/swap 
/tmp/swap: Linux/ppc swap file                                                            

Actual results:
Described as step.2. It fails to get the label, UUID, version and some other info.

Expected results:
It should returns some info like blew:
$ file /tmp/swap
swap: Linux/aarch64 swap file (new style), version 1 (4K pages), size 262143 pages, no label, UUID=4f7874fc-e2a0-4c86-9bc3-b54b5ad19d5a

I you have access to ppc64le and aarch64 machines, could you please create small swap file and upload it somewhere, so I could create and try the patch?
