I use the following CPU configuration with xen & Linux (nested kvm):

<cpu mode='custom' match='exact'>
	<model fallback='allow'>Haswell-noTSX</model>
	<vendor>Intel</vendor>
	<topology sockets='1' cores='4' threads='1'/>
	<feature policy='require' name='abm'/>
	<feature policy='require' name='pdpe1gb'/>
	<feature policy='require' name='rdrand'/>
	<feature policy='require' name='f16c'/>
	<feature policy='require' name='osxsave'/>
	<feature policy='require' name='pdcm'/>
	<feature policy='require' name='xtpr'/>
	<feature policy='require' name='tm2'/>
	<feature policy='require' name='est'/>
	<feature policy='require' name='smx'/>
	<feature policy='require' name='vmx'/>
	<feature policy='require' name='ds_cpl'/>
	<feature policy='require' name='monitor'/>
	<feature policy='require' name='dtes64'/>
	<feature policy='require' name='pbe'/>
	<feature policy='require' name='tm'/>
	<feature policy='require' name='ht'/>
	<feature policy='require' name='ss'/>
	<feature policy='require' name='acpi'/>
	<feature policy='require' name='ds'/>
	<feature policy='require' name='vme'/>
</cpu>

I've put it together from various bits I found all over the Internet.

The CPU model should be whatever is closest to your host. I would also
recommend a newer kernel (Ubuntu 16.04?).
