When calling the query-cpu-model-expansion command via libvirt, we pass in
model
name "max" when using TCG. However, this model name is not supported for s390
on
TCG. Let's use the model name "qemu" as an alternative.
QEMU Results:
When executing query-cpu-model-expansion via QEMU on s390 with TCG, the name
"max"
results in this error:
{ "execute": "query-cpu-model-expansion", "arguments": {"type": "static",
"model": {"name": "max"}}}
-> {"error": {"class": "GenericError", "desc": "The CPU definition 'max' is
unknown."}}
An alternative is to use model name "qemu." On a z13.2 machine:
{ "execute": "query-cpu-model-expansion", "arguments": {"type": "static",
"model": {"name": "qemu"}}}
-> {"return": {"model": {"name": "zEC12.2-base", "props": {"dateh2": false,
"aen": true, "kmac-tdea-192": false,
"kmc-tdea-192": false, "parseh": false, "csske": false, "hfpm": false, "hfpue":
false, "dfp": false, "km-dea": false,
"emon": false, "kimd-sha-1": false, "cmpsceh": false, "dfpzc": false, "dfphp":
false, "kmc-dea": false,
"klmd-sha-1": false, "asnlxr": false, "km-tdea-192": false, "km-tdea-128":
false, "fpe": false, "kmac-dea": false,
"kmc-tdea-128": false, "ais": true, "kmac-tdea-128": false, "nonqks": false,
"pfpo": false, "msa4-base": true,
"msa3-base": true, "tods": false}}}}
I am by all means *not* an expert in TCG, but I noticed this error while I was
messing
around with things on my system.
Thanks!
