You were all excited because you read my other post, but you didn’t pay attention to the part about needing a special version of qemu-kvm and were saddened to be hit with this:

error: unsupported configuration: block copy is not supported with this QEMU binary

Don’t fret, I’ll help you get where you want to go. Do everything as root, and don’t do it on a production system … duh

Get your development environment ready:

# yum install -y rpm-build redhat-rpm-config make gcc
# mkdir -p ~/rpmbuild/{BUILD,RPMS,SOURCES,SPECS,SRPMS}
# echo '%_topdir %(echo $HOME)/rpmbuild' > ~/.rpmmacros

Get your source rpm and prerequisites – note that while this is current as of this posting, things could change. Up to you to handle keeping yourself current:

# wget http://ftp.redhat.com/redhat/linux/enterprise/6Server/en/RHEV/SRPMS/qemu-kvm-rhev-1.5.3-60.el7_0.7.src.rpm
# yum install -y zlib-devel SDL-devel texi2html gnutls-devel cyrus-sasl-devel libtool libaio-devel pciutils-devel pulseaudio-libs-devel libiscsi-devel libattr-devel libusbx-devel usbredir-devel texinfo spice-protocol spice-server-devel libseccomp-devel libcurl-devel glusterfs-api-devel glusterfs-devel systemtap systemtap-sdt-devel nss-devel libjpeg-devel libpng-devel libuuid-devel bluez-libs-devel brlapi-devel check-devel libcap-devel pixman-devel librdmacm-devel iasl ncurses-devel

Build your binary:

# rpmbuild --rebuild qemu-kvm-rhev-1.5.3-60.el7_0.7.src.rpm

Install your binary and its dependencies. Enjoy blockcopy funcitonality:

# yum install -y rpmbuild/RPMS/x86_64/*
