Below are two packages. The first one is installed, the second one is built for Koji. Yum refuses to upgrade the installed package to the second one, saying: Examining qemu-0.15.0-0.2.2011072859fadcc.fc17.x86_64.rpm: 2:qemu-0.15.0-0.2.2011072859fadcc.fc17.x86_64 qemu-0.15.0-0.2.2011072859fadcc.fc17.x86_64.rpm: does not update installed package. But I don't understand why, since it seems clear that the second package has a higher release than the first package. In any case, this appears to be a bug in the versioning of these packages, since the "0.2" part of the release string should have been changed to "0.3" when it was built.

QEMU has two operating modes: * Full system emulation. In this mode, QEMU emulates a full system (for example a PC), including a processor and various peripherials. It can be used to launch different Operating Systems without rebooting the PC or to debug system code. * User mode emulation. In this mode, QEMU can launch Linux processes compiled for one CPU on another CPU. As QEMU requires no host kernel patches to run, it is safe and easy to use. $ rpm -qip qemu-0.15.0-0.2.2011072859fadcc.fc17.x86_64.rpm Name : qemu Epoch : 2 Version : 0.15.0 Release : 0.2.2011072859fadcc.fc17 Architecture: x86_64 Install Date: (not installed) Group : Development/Tools Size : 0 License : GPLv2+ and LGPLv2+ and BSD Signature : (none) Source RPM : qemu-0.15.0-0.2.2011072859fadcc.fc17.src.rpm Build Date : Thu 28 Jul 2011 18:24:13 BST Build Host : x86-07.phx2.fedoraproject.org Relocations : (not relocatable) Packager : Fedora Project Vendor : Fedora Project URL : http://www.qemu.org/ Summary : QEMU is a FAST! processor emulator Description : QEMU is a generic and open source processor emulator which achieves a good emulation speed by using dynamic translation.
