Unable to start CRC on Google cloud VM

[kansal-mukul]

General information

I am access of google cloud on which i spin up one VM and trying to start CRC but everytime i am getting please enable virtualization. i follow this blog : https://www.redhat.com/en/blog/codeready-containers . I tried with many OS (Centos , RHEL etc) but everytime i am not able to run crc setup command . please help and share the correct documents with full steps .

Operating System

Linux

Hypervisor

KVM

Did you run crc setup before crc start?

no

Running on

VM

Steps to reproduce

1. gcloud compute instances create crc-rhel-vm
   --zone=us-east1-b
   --machine-type=c2-standard-8
   --image-family=rhel-8
   --image-project=rhel-cloud
   --boot-disk-size=200GB
   --boot-disk-type=pd-standard
   --no-address
   --min-cpu-platform="Intel Cascade Lake"
   --metadata=startup-script='#!/bin/bash
   sudo yum module install -y virt
   sudo yum install -y virt-install virt-viewer
   sudo systemctl start libvirtd
   sudo systemctl enable libvirtd
   sudo virt-host-validate'
2. ssh into the VM and run sudo dnf install NetworkManager
3. curl -LO https://developers.redhat.com/content-gateway/rest/mirror/pub/openshift-v4/clients/crc/latest/crc-linux-amd64.tar.xz

tar -xvf crc-linux-amd64.tar.xz
mkdir -p ~/bin
cp /home/mukul_kansal/crc-linux-2.47.0-amd64/crc ~/bin
export PATH=$PATH:$HOME/bin
echo 'export PATH=$PATH:$HOME/bin' >> ~/.bashrc
cd crc-linux-2.47.0-amd64/
crc setup

CRC version

CRC status

CRC config

Host Operating System

centos 8 , RHEL . i tried both

Expected behavior

it should complete the CRC setup

Actual behavior

CRC Logs

Additional context

PLease help on this ASAP . this is very urgent because i am working on one POC so planning to use this CRC cluster for further development,

@kansal-mukul you need to enable the nested virtualization flag on Google cloud if you want to use the OpenShift Local because it does create a VM https://cloud.google.com/compute/docs/instances/nested-virtualization/enabling

Any specific reason you can't use your laptop for POC?

[kansal-mukul]

I added this flag (--metadata=google-compute-enable-nested-virtualization=true)in above gcloud command for enable virtualization but that everytime shows that you need to enable virtualization (above screenshot).

I am using windows laptop (that dont have admin rights) . One more reason to use VM as in google cloud we have lots of resources that may required while using CRC for further deployment of application like velero, operators etc. and might we need loadbalancer . So thats teh reason . PLease help @praveenkumar

[praveenkumar]

Have a look to https://github.com/ironcladlou/openshift4-libvirt-gcp/blob/master/provision.sh#L41-L47 one.

might we need loadbalancer

I don't think this can be enabled on CRC side you might need to take a look to https://github.com/crc-org/crc-cloud one

@praveenkumar thanks for sharing but I tried with above video as well but getting error "/lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.28' not found".

Below is the command that i ran 👍
gcloud compute disks create crc-disk --image-project ubuntu-os-pro-cloud --image-family ubuntu-pro-1804-lts --zone us-central1-a

gcloud compute images create crc-v4-image --source-disk crc-disk --source-disk-zone us-central1-a --licenses "https://www.googleapis.com/compute/v1/projects/vm-options/global/licenses/enable-vmx"

gcloud compute disks delete crc-disk --zone=us-central1-a

gcloud compute images delete crc-v4-image

crc config set skip-check-network-manager-installed true then getting error

[kansal-mukul]

IN this article they mentioned that this is not supported . https://crc.dev/docs/installing/

Ubuntu 18.04 LTS or later and Debian 10 or later
Not supported.

Might require manual set up of the host machine.

[kansal-mukul]

Can you suggest which kmage and image family we have to use on which crc will install successfully .

Example :
gcloud compute images create crc-v4-image --source-disk crc-disk --source-disk-zone us-central1-a --licenses "https://www.googleapis.com/compute/v1/projects/vm-options/global/licenses/enable-vmx"

[kansal-mukul]

I tried with these commands : gcloud compute disks create crc-disk --image-project ubuntu-os-cloud --image-family ubuntu-2204-lts --zone us-central1-a

gcloud compute images create crc-v4-image --source-disk crc-disk --source-disk-zone us-central1-a --licenses "https://www.googleapis.com/compute/v1/projects/vm-options/global/licenses/enable-vmx"

gcloud compute instances create crc-vm --disk name=crc-disk,boot=yes --zone us-central1-a --machine-type n1-standard-8 --metadata=google-compute-enable-nested-virtualization=true --no-address

error 👍

Getting this error while running crc setup : crc: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.28' not found (required by crc)

[cfergeau]

/lib/x86_64-linux-gnu/libc.so.6: version 'GLIBC_2.28' not found is expected when using ubuntu-pro-1804-lts. We should update our docs, but at best we'd be "supporting" 22.04

[kansal-mukul]

As per documentation : Ubuntu 18.04 LTS or later and Debian 10 or later
Not supported.

Which ubuntu we have to use ? Is this means Ubuntu 18.04 LTS or later is not supported

Check Ref Link : https://crc.dev/docs/installing/

IN video https://www.youtube.com/watch?v=apV_nhEb4Ss they are using ubuntu-1804-lts

[cfergeau]

IN video https://www.youtube.com/watch?v=apV_nhEb4Ss they are using ubuntu-1804-lts

but this video is 4 years old, we can't support linux distributions forever.

[kansal-mukul]

@cfergeau So please suggest distribution i should use

gcloud compute disks create crc-disk --image-project --image-family --zone us-central1-a

gcloud compute images create crc-v4-image --source-disk crc-disk --source-disk-zone us-central1-a --licenses "https://www.googleapis.com/compute/v1/projects/vm-options/global/licenses/enable-vmx"

gcloud compute instances create crc-vm --disk name=crc-disk,boot=yes --zone us-central1-a --machine-type n1-standard-8 --min-cpu-platform "Intel Haswell" --enable-nested-virtualization --no-address

[cfergeau]

I'd recommend something fedora/rhel/centos based, and less than 2 years old as this is what we are testing.
