[PATCH v5 05/12] cryptodev: Introduce 'query-cryptodev' QMP command |
Date: |
Wed, 1 Mar 2023 10:51:17 +0800 |
Now we have a QMP command to query crypto devices:
virsh qemu-monitor-command vm '{"execute": "query-cryptodev"}' | jq
{
"return": [
{
"service": [
"akcipher",
"mac",
"hash",
"cipher"
],
"id": "cryptodev1",
"client": [
{
"queue": 0,
"type": "builtin"
}
]
},
{
"service": [
"akcipher"
],
"id": "cryptodev0",
"client": [
{
"queue": 0,
"type": "lkcf"
}
]
}
],
"id": "libvirt-417"
}
