Installation of Windows 7 Ultimate x86 (32-bit) Service Pack 1 on a guest with more than 4GB of RAM and more than one CPU from a DVD medium often crashes during the final steps of the installation process due to a system hang. To work around this issue, use the Windows Update utility to install the Service Pack.

Xiaoqing Wei, I cannot reproduce the problem, after 10 installation attempts, with Windows 7 Ultimate 32-bits, on Intel host. This is the command line: /usr/libexec/qemu-kvm -drive file=/root/images/win7_ultimate.img,cache=writeback \ -m 8G -vnc :1 \ -net nic,vlan=0,macaddr=20:20:20:00:00:02,model=rtl8139 \ -net tap,script=/root/ifup.sh -monitor telnet:127.0.0.1:4445,server,nowait \ -cdrom /root/en_windows_7_ultimate_x86_dvd_x15-65921.iso \ -cpu cpu64-rhel6,+sse2,+x2apic -usbdevice tablet -enable-kvm -boot d \ -smp 4,cores=2,threads=1,sockets=2 qemu-kvm-0.12.1.2-2.160.el6 kernel-2.6.32-131.0.15.el6 From RHEL6.1. Can you please reproduce and confirm that: 1) Booting with 4G fixes the problem. 2) Booting with smp=1 (uniprocessor) fixes the problem. 3) Using AMD machine fixes the problem.

This combination (+4GB memory on 32-bit guest, SP1 installation from DVD) is very uncommon, so adding an entry Technical Notes should be enough. ----------- Cause Installation of Windows 7 Ultimate x86 (32-bit) Service Pack 1 on guest with more than 4GB of RAM and more than one CPU often crashes during final steps. Consequence Installation fails due to a system hang. Workaround Avoid installing Windows 7 Ultimate x86 Service Pack 1 from DVD media, in case guest uses more than 4GB of RAM. Instead, use Windows Update to install Service Pack 1. What's the explanation it works for Marcelo and not for QE? Can you two share the host cpu info? Also, I recommend not to use -cpu qemu64 but use -cpu Nehalem. Can QE retest with it? I do like to treat it as exception and find the cause till the exception phase ends.
