Hello, After rebasing to latest master (at least 08be92), if you want to reuse your prefix, please: $ rm -fr "${HOME}/ovirt-engine/share/ovirt-engine/setup" $ make install-dev PREFIX="${HOME}/ovirt-engine" DEV_REBUILD=0 This will remove some leftovers and allow you to reuse your current prefix. I submitted a patch[1] to automate this process, I hope it will be merged soon, but its effect is only for the N+1 deployment. Sorry for the inconvenience. Regards, Alon Bar-Lev.
