Description of problem: I installed RHEL56-20101110.0 to intel-w3520 host, when I boot up a rhel56 guest, it hangs(attached a screendump), then host it's too slow. But rhel48, rhel55 guest can boot up successfully. This bug can only be reproduced on intel-w3520 machine. Version-Release number of selected component (if applicable): tree: RHEL5.6-Server-20101110.0 kernel: 2.6.18-231.el5 kmod-kvm-83-207.el5 etherboot-zroms-kvm-5.4.4-13.el5 etherboot-roms-kvm-5.4.4-13.el5 kvm-debuginfo-83-207.el5 kvm-83-207.el5 kvm-qemu-img-83-207.el5 kvm-tools-83-207.el5 kmod-kvm-debug-83-207.el5 How reproducible: 100% on intel-w3520 Steps to Reproduce: 1. install RHEL56-20101110.0 to a intel-w3520 machine 2. boot up a rhel56 guest on it Actual results: rhel56 guest hangs during boot up Expected results: rhel56 guest can boot up succesfully Additional info: # ps aux |grep qemu root 16802 0.7 0.0 685288 3200 ?
