Description Richard W.M. Jones 2013-02-06 12:35:18 UTC

+++ This bug was initially created as a clone of Bug #908255 +++

Description of problem:

[root@hp-z220-01 images]# virt-cat  RHEL-Server-6.0-32-hvm.raw /etc                                                    
libguestfs: error: file receive cancelled by daemon
libguestfs: error: /dev/stdout: error in chunked encoding

Note it's wrong to use virt-cat with a directory name, but the
problem is that the real error message is lost.

Simple reproducer from within the libguestfs source tree:

$ ./run ./cat/virt-cat -a ./tests/guests/fedora.img /etc
libguestfs: error: file receive cancelled by daemon
libguestfs: error: /dev/stdout: error in chunked encoding

Comment 1 Richard W.M. Jones 2013-02-06 13:41:08 UTC

The following upstream fix:

https://github.com/libguestfs/libguestfs/commit/f9bafde5e7f1302ce7c5ea304e51a8d90a323b58

adds an extra check that the download file is not a directory,
and gives the following error:

$ ./run ./cat/virt-cat -a ./tests/guests/fedora.img /etc 
libguestfs: error: download: /etc: is a directory
