| Eduardo Habkost | 2014-04-16 19:16:43 UTC | 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: | |

Consequence: Windows 8.1 and Windows 2012R2 won't boot if using the following CPU models: Opteron_G1, Conroe, kvm64.

Result: | Microsoft Windows 8.1 and Microsoft Windows Server 2012 R2 require some CPU features, for example Compare Exchange 8Byte and Compare Exchange 16Byte, which are not present in all qemu-kvm CPU models. As a consequence, Microsoft Windows 8.1 and Microsoft Windows Server 2012 R2 guests do not boot if they use the following CPU model definitions: Opteron_G1, Conroe, and kvm64. To work around this problem, use CPU models that include the features required by Microsoft Windows 8.1 and Microsoft Windows Server 2012 R2, for example Penryn, Nehalem, Westmere, SandyBridge, Haswell, Opteron_G2, Opteron_G3, Opteron_G4, or Opteron_G5. |
