I am installing QEMU in RHEL. In 32 bit OS (i686 architecture), if I run the command, yum install qemu, the installation of QEMU takes place. However, in 64 bit architecture (x86_64), if I run the same command, I am getting the error as QEMU package not available. Is the yum installation dependent on the architecture of the OS version?EDIT:This is the output of yum list |grep qemuqemu.i386                             2:0.10.5-1.el5.2        installedqemu-common.i386                      2:0.10.5-1.el5.2        installedqemu-img.i386                         2:0.10.5-1.el5.2        installedqemu-system-arm.i386                  2:0.10.5-1.el5.2        installedqemu-system-cris.i386                 2:0.10.5-1.el5.2        installedqemu-system-m68k.i386                 2:0.10.5-1.el5.2        installedqemu-system-mips.i386                 2:0.10.5-1.el5.2        installedqemu-system-ppc.i386                  2:0.10.5-1.el5.2        installedqemu-system-sh4.i386                  2:0.10.5-1.el5.2        installedqemu-system-sparc.i386                2:0.10.5-1.el5.2        installedqemu-system-x86.i386                  2:0.10.5-1.el5.2        installedqemu-user.i386                        2:0.10.5-1.el5.2        installed 
QEMU package not available for RHEL 64 bit
linux;rhel;qemu
Your 64 bit system does not have the appropriate external repository defined for the 64-bit QEMU packages. You will need to find a repository with these packages available and install the appropriate .repo file in /etc/yum.repos.d/ before you can yum install the QEMU packages. A quick Google search shows that RepoForge has 64-bit QEMU packages available, so that would be a good starting point.
