Description of problem: My CPU: Intel(R) Core(TM)2 Duo CPU T9600 @ 2.80GHz flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx lm constant_tsc arch_perfmon pebs bts rep_good nopl aperfmperf pni dtes64 monitor ds_cpl vmx smx est tm2 ssse3 cx16 xtpr pdcm sse4_1 lahf_lm dts tpr_shadow vnmi flexpriority Yet when clicking on 'copy host CPU information', I'm not getting many of these flags. Specifically, I miss the SSE* flags which actually do something.

How are you verifying that these flags aren't copied? The way this works in virt-manager is that we specify to qemu the -cpu model that covers the largest subset of your host CPU flags, then only manually copy over +flags that are not associated with that model, but which your host exposes. I'm pretty sure we are doing the correct thing here, so closing NOTABUG. If you still think there is an issue, please provide virsh dumpxml $vmname (as root) /var/log/libvirt/qemu/$vmname.log

You are partially correct. I see the flags in the guest - but they are NOT checked in the 'CPU Features' list. So I suspect a GUI bug (although I don't see it in the XML neither, I suspect it's 'inherited' from the CPU definition.).
Okay, thanks for following up, fixed upstream now: http://git.fedorahosted.org/git?p=virt-manager.git;a=commit;h=cbaedd87bcfd44c3a8bdf99891c31ec9f41e3d0b The CPU feature list now shows a bit more info about the flags passed to the guest. Flags marked as 'model' mean they are implied by the choice of CPU model. At the libvirt level, flags implied by a CPU model choice do not show up in the XML.
