KVM Advanced CPU settings

[jlw52761]

Where does one look for the VM config files? I need to set/add the following options to a VM for KVM/QEMU.

Code:

<cpu mode="custom" match="exact" check="full">
<model fallback="forbid">Haswell-noTSX-IBRS</model>
<vendor>Intel</vendor>
<feature policy="require" name="vme"/>
<feature policy="require" name="ss"/>
<feature policy="require" name="vmx"/>
<feature policy="require" name="f16c"/>
<feature policy="require" name="rdrand"/>
<feature policy="require" name="hypervisor"/>
<feature policy="require" name="arat"/>
<feature policy="require" name="tsc_adjust"/>
<feature policy="require" name="umip"/>
<feature policy="require" name="ssbd"/>
<feature policy="require" name="xsaveopt"/>
<feature policy="require" name="pdpe1gb"/>
<feature policy="require" name="abm"/>
</cpu>
