Do we represent Westmere as being natively supported in 5.7? (In reply to comment #0) > 2. host > 1). kernel: 2.6.18-238.el5 > 2). host x86info: : > Feature flags: > fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflsh > ds acpi mmx fxsr sse sse2 ss ht tm pbe sse3 pclmuldq dtes64 monitor ds-cpl vmx > smx est tm2 ssse3 cx16 xTPR pdcm pcid dca sse4_1 sse4_2 popcnt aes x86info is reporting aes on the host however 5.x qemu-kvm isn't aware of this feature flag. qemu will complain about this request: # x86_64-softmmu/qemu-system-x86_64 -hda ../../rhel5.4.img -vnc :18 -net nic -net user -m 1024 -cpu qemu64,+aes CPU feature aes not found however it will not fail to launch in this situation similar to the scenario of the user requesting a known feature flag which isn't present on the host. This is standard behavior for 5.x qemu. |
