| Doc Text | Cause: Windows 8.1 and Windows 2012R2 require some CPU features that are not present in all qemu-kvm CPU models. e.g.: CMPXCHG8B ("cx8") and CMPXCHG16B ("cx16"). Consequence: Windows 8.1 and Windows 2012R2 won't boot if using the following CPU models: Opteron_G1, Conroe, kvm64. Workaround (if any): Use CPU models that include the features required by Windows 8.1 and Windows 2012 R2, e.g.: Penryn, Nehalem, Westmere, SandyBridge, Haswell, Opteron_G2, Opteron_G3, Opteron_G4, Opteron_G5.

Result: | Windows 8.1 and Windows 2012 R2 require some CPU features that are not present in all qemu-kvm CPU models. Consequently, Windows 8.1 and Windows 2012 R2 do not boot they if certain CPU models are used, namely Opteron_G1, Conroe, and kvm64. To work around this problem, use CPU models that include the features required by Windows 8.1 and Windows 2012 R2, for example Penryn, Nehalem, Westmere, SandyBridge, Haswell, Opteron_G2, Opteron_G3, Opteron_G4, Opteron_G5. |
