The virDomainDefParseXML function has grown so large it broke the build: ../../src/conf/domain_conf.c:20362:1: error: stack frame size of 4168 bytes in function 'virDomainDefParseXML' [-Werror,-Wframe-larger-than=] Signed-off-by: Ján Tomko <jtomko(a)redhat.com&gt; --- Technically a build breaker fix.
