[Qemu-devel] CPU Model kvm64 and Windows2012R2

2015-08-24 Thread Peter Lieven
Hi, I noticed that Win2012R2 will not boot with CPU model kvm64. The reason is that the feature lahf_lm is missing. Is that an error or correct? Thanks, Peter

Hi, some very old 64-bit processors had virtualization extensions but not lahf_lm. However, they are very rare, so it is probably a good idea to add it for the 2.5 machine type. Thanks, Paolo Inviato dal telefono Android mediante TouchDown (www.nitrodesk.com) -Original Message- From:
