Why is this file needed?
"
Here we are testing default value conversion. That is:
if there is no apci/pae/apic specified in xm config, after conversion,
libvirt xml should include:
<features>
<apic/>
<acpi/>
<pae/>
</features>
So, from xm config -> xml, the cfg file should be like this.

IMO, this file should be renamed to 'test-fullvirt-default-feature.cfg'.
And from xml -> xm config, if in xml there is:
<features>
<apic/>
<acpi/>
<pae/>
</features>
Then after conversion, in xm config out file there will be explicitly:
acpi=1
apic=1
pae=1
So, thlis is a little different from test-fullvirt-default-feature.cfg.

With the change suggested above, this hunk can be removed from
xmconfigtest.c. 'make check' passes for me with these changes.
'make check' could pass, since it explicitly specify acpi|pae|apic=1 in
xm config, and explicitly include those features in xml. But our interested
case is not tested, what we are trying to test is: if user doesn't specify
acpi|pae|apic, xml should by default include those features.

Was
there any reason for test-fullvirt-default-feature.cfg vs
test-fullvirt-default-feature.cfg?
