How to setup Redfish with libvirt - Sushy tools

Environment

Centos8 / RHEL8

Steps

1.Install required package:

# yum install -y python3 python3-libvirt
# pip3 install sushy-tools 

2.Create sushy service file:

# vim /usr/lib/systemd/system/sushy.service
[Unit]
Description=Sushy Libvirt emulator
After=syslog.target

[Service]
Type=simple
ExecStart=/usr/local/bin/sushy-emulator --config /etc/sushy.conf
StandardOutput=syslog
StandardError=syslog

3.Creat sushy service configuration file:

# vim /etc/sushy
SUSHY_EMULATOR_LISTEN_IP = '0.0.0.0'
SUSHY_EMULATOR_LISTEN_PORT = 8000
SUSHY_EMULATOR_SSL_CERT = None
SUSHY_EMULATOR_SSL_KEY = None
SUSHY_EMULATOR_OS_CLOUD = None
SUSHY_EMULATOR_LIBVIRT_URI = u'qemu+ssh://root@${libvirtd_host_ip}/system'
SUSHY_EMULATOR_IGNORE_BOOT_DEVICE = True
SUSHY_EMULATOR_BOOT_LOADER_MAP = {
    u'UEFI': {
        u'x86_64': u'/usr/share/OVMF/OVMF_CODE.secboot.fd',
        u'aarch64': u'/usr/share/AAVMF/AAVMF_CODE.fd'
    },
    u'Legacy': {
        u'x86_64': None,
        u'aarch64': None
    }
}

4.Start and enable sushy.service:

# systemctl enable --now sushy

5.Configure no password login to root@:

# ssh-keygen 
# ssh-copy-id root@<libvirtd host>

6.Now you should be able to see your libvirt domain among the Redfish Systems:

# curl http://localhost:8000/redfish/v1/Systems/

{
    "@odata.type": "#ComputerSystemCollection.ComputerSystemCollection",
    "Name": "Computer System Collection",
    "Members@odata.count": 8,
    "Members": [
        
            {
                "@odata.id": "/redfish/v1/Systems/f091dec2-5660-4c71-b941-23134b6e1ea2"
            },
        
            {
                "@odata.id": "/redfish/v1/Systems/cd878746-6142-40a4-8b1a-5f1952fac4be"
            },
        
            {

            },
        
            {
                "@odata.id": "/redfish/v1/Systems/c4d0dc1f-1a40-493a-8193-432aaa0c6ff3"
            },

            },
        
            {
                "@odata.id": "/redfish/v1/Systems/d5f8d009-1da9-4e2e-b293-eab53d742b0b"
            },
        
            {

            },
        
            {
                "@odata.id": "/redfish/v1/Systems/63a9868c-134a-4d0c-b0c7-e1b26444f1b4"
            }
        
    ],
    "@odata.context": "/redfish/v1/$metadata#ComputerSystemCollection.ComputerSystemCollection",

7.You should be able to flip its power state via the Redfish call:

# curl -d '{"ResetType":"On"}' -H "Content-Type: application/json" -X POST http://localhost:8000/redfish/v1/Systems/f091dec2-5660-4c71-b941-23134b6e1ea2/Actions/ComputerSystem.Reset
# curl -d '{"ResetType":"ForceOff"}' -H "Content-Type: application/json" -X POST http://localhost:8000/redfish/v1/Systems/f091dec2-5660-4c71-b941-23134b6e1ea2/Actions/ComputerSystem.Reset
