General information

Cannot start crc with microshift preset on Fedora 42.

Operating System

Linux

Hypervisor

KVM

Did you run crc setup before crc start?

yes

Running on

Laptop

Steps to reproduce

1. crc config set preset microshift
2. crc setup
3. crc start

CRC version

$ crc version
CRC version: 2.56.0+cb4c91
OpenShift version: 4.20.1
MicroShift version: 4.20.0

CRC status

$ crc status
ERRO crc does not seem to be setup correctly, have you run 'crc setup'?

CRC config

$ crc config view 
- consent-telemetry                     : no
- preset                                : microshift

Host Operating System

NAME="Fedora Linux"
VERSION="42 (Workstation Edition)"

Expected behavior

CRC is started.

Actual behavior

$ crc start

@odockal can you also provide the output of crc setup --log-level debug because may be the socket is not active or service is not running?

[odockal]

@praveenkumar You are right, it seems like the problem. I have updated the log in description, check it out.

[praveenkumar]

@odockal can you provide following command output after running (no need to start)

$ crc cleanup
$ crc setup 

$ systemctl --user status crc-daemon.service
$ curl -X GET --unix-socket $HOME/.crc/crc-http.sock http:/c/api/config | jq .
{
  "Configs": {
    "bundle": "/home/prkumar/.crc/cache/crc_libvirt_4.20.5_amd64.crcbundle",
    "consent-telemetry": "no",
    "cpus": 4,
[...]
  }
}
 
$ journalctl --user -u crc-daemon.service
