Error starting machine: Error in driver during machine start: Unable to determine VM's IP address, did it fail to boot?

The debug log shows DEBU systemd-networkd.service is not running, so I enabled and started it, but than crc start complains it cannot work with systemd-networkd.service, so I stopped and disabled it again.

I also see errors about systemctl status virtqemud.socket' which cannot be found (not running nor listening). It was my understanding that this should be available when installing libvirt-daemon-system`. I installed the following applications:

sudo apt install qemu-system qemu-kvm qemu-utils libvirt-daemon-system libvirt-clients bridge-utils virt-manager virtiofsd

Am I missing another library here?
I understand libvirtd is moving away from monolith to modules. I didn't get the modular approach to work though.

CRC config

- consent-telemetry : no
- cpus : 6
- memory : 12000

Steps to reproduce

  1. Booting QEMU from Windows 11 host (with 64 GB RAM) using a batch file with the following options (using networking mode NAT). I noticed the crc network runs in bridge mode and thought that might be a problem. I tried to run QEMU in bridge, but didn't get that to work together with SPICE (the image won't boot if I use bridge mode).

    @echo off

setlocal enabledelayedexpansion

:: Define the QEMU executable
set "QEMU_EXE=qemu-system-x86_64.exe"

:: Define the image name you want to check
set "IMAGENAME=ubuntu_24_04_openshift"

:: Define the image path and name
set "IMAGE=%QEMU_VMS%\ubuntu_24_04_openshift.img"

:: Check if the QEMU process is running with the specified image
tasklist /v /fi "IMAGENAME eq %QEMU_EXE%" | findstr /i "%IMAGENAME%" >nul

:: Check the exit code of findstr
if %ERRORLEVEL% == 0 (
    echo QEMU is already running image %IMAGENAME%. Exiting.
    exit /b 1
)

  echo %PATH% | findstr /i /c:"!SEARCH_STRING!" >nul
  if !errorlevel!==0 (
    start "" cmd /c virt-view.bat
  )
)

endlocal

  2. Checked if NetworkManager is installed and running on Ubuntu guest. This was the case.

  3. Installed QEMU and related applications on Ubuntu guest, enabled and started libvirtd:

    sudo apt update
sudo apt install qemu-system qemu-kvm qemu-utils libvirt-daemon-system libvirt-clients bridge-utils virt-manager virtiofsd
sudo systemctl enable libvirtd
sudo systemctl start libvirtd

  4. crc setup

  5. crc start

  6. crc config set cpus 6

  7. crc config set memory 12000

  8. Added the following to /etc/hosts oh Ubuntu guest:

    127.0.0.1 console-openshift-console.apps-crc.testing
127.0.0.1 api.crc.testing

Expected

CRC to start succesfully and

Actual

crc start takes a long time, and log shows 60 tries to GetIP for crc.
Doing another start shows:

Use the 'oc' command line interface:
  $ eval $(crc oc-env)
  $ oc login -u developer https://api.crc.testing:6443

But a crc status shows:

CRC VM:          Running
OpenShift:       Unreachable (v4.16.0)
Disk Usage:      0B of 0B (Inside the CRC VM)
Cache Usage:     29.05GB
Cache Directory: /home/itsme/.crc/cache

The CRC VM is running, but OpenShift is unreachable because it didn't get an IP assigned?

Logs

Before gather the logs try following if that fix your issue

$ crc delete -f
$ crc cleanup
$ crc setup
$ crc start --log-level debug

Please consider posting the output of crc start --log-level debug on http://gist.github.com/ and post the link in the issue.

Older (related?) bugs/posts?

I have seen older other similar bugs around here:
@Manfred73 Manfred73 added kind/bug Something isn't working status/need triage labels Aug 9, 2024

@Manfred73 Hi, If I understood correctly you are trying to run crc on a ubuntu VM which is running on windows machine. Why can't you directly use crc on that windows machine ? In past we also issue which raised by users are using nested virt (check the label) and in your case also it is same. We don't perform nested virtualization so not even sure why it is happen, Also we recently did 2.40.0 release try that and see if that works (it fixes one of the issue crc-org/machine-driver-libvirt#122 if underlying hardware is AMD one)

I want to use an Ubuntu/Linux image with crc and other tooling pre installed for training purposes, so I can easily share the image. Some users will have macOS, some Linux and some Windows. First I tried Virtual Box, but understood that doesn't work at all with nested virt and crc. I understood QEMU did supporr this.

Are there workarounds for this, or assigning IP manually.
I will try the newer version also.

Update: I tried version 2.40.0. Unfortunately still the same issue.

Check the logs under /var/log/libvirt/qemu/crc.log and see if there is any error, otherwise VM should able to get the IP automatic. Also you can try following if that help

$ crc delete
$ crc cleanup
$ crc config set network-mode user
$ crc setup
$ crc start

I do see one error related to libvirtd in the crc.log (see log attached):
crc.log

libvirt:  error : libvirtd quit during handshake: Input/output error
2024-08-08 22:07:04.951+0000: shutting down, reason=failed
2024-08-09 05:21:30.494+0000: Starting external device: virtiofsd

I also followed the steps you mentioned before, but without the crc config set network-mode user. I have tried them again, including this option which seems to do something.

I did crc delete followed by crc cleanup:

$ crc config set network-mode user
Network mode changed. Please run `crc cleanup` and `crc setup`.

It suggests I do crc cleanup again, which results in an error (unexpected AppArmor template file /etc/apparmor.d/libvirt/TEMPLATE.qemu, cannot configure it automatically):

$ crc cleanup

Then crc setup:

Your system is correctly setup for using CRC. Use 'crc start' to start the instance

Now, doing a crc start gives the following error (failed to expose port 127.0.0.1:2222 -> 192.168.127.2:22: listen tcp 127.0.0.1:2222: bind: address already in use):

When I stop gitlab and try crc start again, it fails on port 80 (I have another docker image running with also uses port 80):

Should I run these docker images on another port? Or can I configure crc to use others?

I have stopped both docker images and did another:

$ crc delete
$ crc cleanup
$ crc config set network-mode user
$ crc setup
$ crc start

This results in errors:

On the Ubuntu guest I have a config file defined in the .ssh for the docker images I'm running which need ssh with identity file. Is this causing a problem for crc?

I think following explain it, looks like libvirt is not working at all properly and VM is not running, you can check status of the VM using sudo virsh list --all and might see the VM in stopped state. This might be the reason why ssh is failing.

I create a complete new Ubuntu image and right after that installed prerequisites for crc (docker, libvirt):

sudo apt install qemu-system qemu-kvm qemu-utils libvirt-daemon-system libvirt-clients bridge-utils virt-manager virtiofsd

Right after that installed crc:

crc config set network-mode user
crc setup
crc start

crc status shows:

sudo virsh list --all shows:

In the crc.log I still see ssh handshake errors:

We can only debug more around this if it can reproduce in our testing/dev environment and which is not the case :( . There is lot of things depend for failure like base/guest HyperVisor and also underlying hardware. As I told before nested-virt tests are not something we perform or encourage users to do it. If possible try on native hypervisor to see if it still fails instead nested-virt.
