Limited CPU support for Windows 10 and Windows Server 2016 guests
On a Red Hat Enterprise 6 host, Windows 10 and Windows Server 2016 guests can only be created when using the following CPU models:
* the Intel Xeon E series
* the Intel Xeon E7 family
* Intel Xeon v2, v3, and v4
* Opteron G2, G3, G4, G5, and G6
For these CPU models, also make sure to set the CPU model of the guest to match the CPU model detected by running the "virsh capabilities" command on the host. Using the application default or hypervisor default prevents the guests from booting properly.
To be able to use Windows 10 guests on Legacy Intel Core 2 processors (also known as Penryn) or Intel Xeon 55xx and 75xx processor families (also known as Nehalem), add the following flag to the Domain XML file, with either Penryn or Nehalem as MODELNAME:
<cpu mode='custom' match='exact'>
<feature name='erms' policy='require'/>
Other CPU models are not supported, and both Windows 10 guests and Windows Server 2016 guests created on them are likely to become unresponsive during the boot process.
