Figured I'd test qemu-kvm-1.0.1 and libvirt-0.9.12, but the result after default compiles is: root@black:/usr/local/sbin# ./libvirtd 2012-06-12 19:53:41.894+0000: 6076: info : libvirt version: 0.9.12 2012-06-12 19:53:41.894+0000: 6076: warning : ebiptablesDriverInit:4084 : Could not find 'ebtables' executable 2012-06-12 19:53:42.675+0000: 6076: error : qemuCapsComputeCmdFlags:1209 : unsupported configuration: this qemu binary requires libvirt to be compiled with yajl 2012-06-12 19:53:42.677+0000: 6076: error : virDomainDefParseXML:8312 : internal error No guest options available for arch 'x86_64' Is it just the "yajl" thing missing, or is this combo just not to be expected to work?

Also, should http://libvirt.org/compiling.html mention "yajl"?

Need to install yajl-devel rpm package.

Obviously, this probe would have to be tolerant of qemu not existing, but erroring out earlier than runtime might help people build correctly since this seems to be a recurring question on the list. And it must not break on RHEL 5, where qemu is old enough to not require yajl and where yajl is not available by default.
