(just the same as --disable-qemu-traditional). thanks Lan [1] commit 5c7cbadaccca8dbb47f2c42ab1b5a8afac9275e3 Author: Ian Campbell <ian.campbell@xxxxxxxxxx> Date: Wed May 15 14:47:32 2013 +0100 tools: allow user to specify a system qemu-xen binary If this option is given don't bother building qemu-xen ourselves. Likely to be handy for distros who have an existing qemu package which they want to reuse. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
