Description Daniel Berrangé 2013-04-12 16:33:10 UTC 
Description of problem:
Currently libvirt has code to initialize libgcrypt, as a pre-requisite to using gnutls. As a result libvirt also explicitly links to -lgcrypt.

In gnutls 3.x libgcrypt is replaced by libnettle. Libvirt's explicit initialization of libgcrypt is thus bogus and is causing libvirt to link to two crypto libraries (gcrypt + nettle).

Libvirt's libgcrypt init code should be made conditional so we don't use it when gnutls is linked to nettle.

Version-Release number of selected component (if applicable):
libvirt-1.0.4-1.el7

How reproducible:
Always

Steps to Reproduce:
1. $ ldd /lib64/libvirt.so.0 | grep gcrypt
2.
3.
  
Actual results:
	libgcrypt.so.11 => /lib64/libgcrypt.so.11 (0x0000003441800000)

Expected results:
Does not link to gcrypt

v3 of upstream patch; missed 1.1.1 so it will need a backport
