Hi! i wanted to test these patches against http://xenbits.xensource.com/xen-unstable.hg but it seems to check out an outdated version of upstream-qemu, even with "QEMU=upstream". Where can i check out the qemu-upstream version to which these patches apply? Thanks and Greetings Tobias Am Freitag, 17.
