well, 1.0.6 is out of the door, but with this I hit the following
problem on Ubuntu 12.04 (gcc 4.6.3):
../../src/conf/domain_conf.c: In function 'virDomainHostdevDefParseXML':
../../src/conf/domain_conf.c:3915:36: error: 'next_unit' may be used
uninitialized in this function [-Werror=uninitialized]
../../src/conf/domain_conf.c:3886:9: note: 'next_unit' was declared here
It seems that the older compiler is not smart enough to grasp the tie
between 'found' and 'next_unit'...
fixed by Jirka with 4db39e3fee6
