T2500 is also older Core Duo (coreduo) processor.
Reproduced from command line: succesfully installed & running winxp sp3
with "kvm -cpu coreduo,-nx".
How do I define "no NX" this in /etc/libvirt/qemu/winxp.xml
configuration file?
<domain>
<cpu name='coreduo'>
<feature name='nx' option='disable'/>
</cpu>
-> won't work, nx feature is not disabled.
neither success with less documented xml file options/features:
<os>
<type arch='i686' machine='pc'>hvm</type>
<feature name='nx' policy='disable'/>
<feature name='nx' option='disable'/>
<feature name='nx' mode='set' value='off'/>
<boot dev='hd'/>
</os>
<cpu model='coreduo,-nx'>
<feature name='nx' policy='disable'/>
<feature name='nx' option='disable'/>
<feature name='nx' mode='set' value='off'/>
</cpu>
