Also verified that RHEL 6 guest gets core2duo CPU when Westmere is selected. I can also verify this. I have a i7 cpu and if I "copy host cpu configuration" it sets it to "Westmere" but when running ps shows -cpu core2duo If I run qemu-kvm with -cpu Westmere I get an error message: Unable to find x86 CPU definition Westmere is not a defined -cpu in qemu for F15. Available options for -cpu can be seen with qemu -cpu ?: x86 [n270] x86 [athlon] x86 [pentium3] x86 [pentium2] x86 [pentium] x86 [486] x86 [coreduo] x86 [kvm32] x86 [qemu32] x86 [kvm64] x86 [core2duo] x86 [phenom] x86 [qemu64] Though perhaps libvirt shouldn't try to set unsupported -cpu flags. This is still happening in Fedora 16 This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component. *** This bug has been marked as a duplicate of bug 804224 *** |
Description of problem: Configured Windows7 virtual machine with Westmere CPU in Virtual Machine Manager, but ps + iotop shows qemu always using the core2duo setting. Version-Release number of selected component (if applicable): qemu-kvm-0.14.0-7.fc15.x86_64 How reproducible: ALWAYS Steps to Reproduce: 1. Create Virtual Machine 2. Set CPU to Westmere (or other) 3. Run virtual machine 4. ps -ef | grep -i qemu 5. qemu-kvm shows cpu as core2duo instead of Westmere. Actual results: core2duo as qemu-kvm flag Expected results: Westmere as qemu-kvm flag Additional info: Output from PS: qemu 19566 1 25 00:03 ? 00:05:02 /usr/bin/qemu-kvm -S -M pc-0.14 -cpu core2duo Output from /etc/libvirt/qemu/Windoz7.xml <cpu match='exact'> <model>Westmere</model> <vendor>Intel</vendor> <feature policy='require' name='tm2'/> <feature policy='require' name='est'/> <feature policy='require' name='monitor'/> <feature policy='require' name='ss'/> <feature policy='require' name='vme'/> <feature policy='require' name='rdtscp'/> <feature policy='require' name='ht'/> <feature policy='require' name='ds'/> <feature policy='require' name='pbe'/> <feature policy='require' name='tm'/> <feature policy='require' name='vmx'/> <feature policy='require' name='ds_cpl'/> <feature policy='require' name='xtpr'/> <feature policy='require' name='acpi'/> </cpu>
