[libvirt] [PATCH] disable xenlight for non-Xen platforms
by Dan Horák 11 Oct '11

11 Oct '11

Hi, when building libvirt in Fedora/s390x I've found that xenlight needs to be explicitly disabled in the spec file. Configure properly sets the library as non-existent, but the %files section still wants to package the 3 /var/*/libvirt/libxl directories. See also https://bugzilla.redhat.com/show_bug.cgi?id=745020 With regards, Dan
