So you assert here that the feature is available ...
assert_has_feature(qts, "host", "kvm-steal-time");
assert_has_feature(qts, "host", "sve");
resp = do_query_no_props(qts, "host");
+ kvm_supports_pmu_filter = resp_get_feature_str(resp,
"kvm-pmu-filter");
kvm_supports_steal_time = resp_get_feature(resp,
"kvm-steal-time");
kvm_supports_sve = resp_get_feature(resp, "sve");
vls = resp_get_sve_vls(resp);
qobject_unref(resp);

... why do you then need to check for its availability here again?
I either don't understand this part of the code, or you could drop the
kvm_supports_pmu_filter variable and simply always execute the code below.
Thanks for your reviewing. I did so because all other feature like
"kvm-steal-time" check its availability again. I don't know the original
reason why they did that. I just followed it.
Do you think we should delete all the checking?
resp_get_feature() seems to return a boolean value, so though these feature
could be there, they still could be disabled, I assume? Thus we likely need
to keep the check for those.
