Get the RedHat source rpm from: $ wget wget http://cbs.centos.org/kojifiles/packages/qemu-kvm-ev/2.3.0/31.el7_2.7.1/src/qemu-kvm-ev-2.3.0-31.el7_2.7.1.src.rpm Uncompress the source rpm: $ rpm2cpio qemu-kvm-ev-2.3.0-31.el7_2.7.1.src.rpm | cpio -idmv All the patches from the redhat source rpm have been applied in git/qemu using scripts/autopatch.sh. Some of these patches can't be applied cleanly with 'git am'. So this script attempd to execute 'git am' on each of them, if it fails it tries to patch the files manually with 'git apply --index'. A git tag 'qemu-kvm-ev-2.3.0-31.el7_2.7.1' has been added to the last patch applied. The Titanium Cloud specific patches will be added after this tag.
