At least on Fedora, xen's qemu binaries now always live in /usr/lib/xen/bin (even on x86_64). Per the package changelog this was changed in 4.5.0-1, in January. Existing Xen VMs on x86_64 Fedora are now broken (because they look in /usr/lib64) and you can't create a new one (because it looks in /usr/lib64). This is affecting at least F22 and F23. Patch should be something like: diff --git a/src/xen/xen_hypervisor.c b/src/xen/xen_hypervisor.c index 431c47a..e7fff85 100644 --- a/src/xen/xen_hypervisor.c +++ b/src/xen/xen_hypervisor.c @@ -2144,9 +2144,7 @@ xenHypervisorBuildCapabilities(virConnectPtr conn, virArch hostarch, if ((guest = virCapabilitiesAddGuest(caps, guest_archs[i].hvm ?

Yeah I think the xen package needs to add symlinks at least, since otherwise there's no way to fix pre-existing VMs which have the lib64 path in their XML.
