cf dev start: unable to find VM IP address from '/var/lib/libvirt/dnsmasq/virbr0.status'

[karizma987]

although i found the same error being solved but it is not working for me. i am new to cloud foundry.
i am trying to install cloud foundry dev.
i used the following command.

sudo apt install qemu-kvm libvirt-bin libvirt-doc
wget -q -O - https://packages.cloudfoundry.org/debian/cli.cloudfoundry.org.key | sudo apt-key add -
echo "deb https://packages.cloudfoundry.org/debian stable main" | sudo tee /etc/apt/sources.list.d/cloudfoundry-cli.list
# ...then, update your local package index, then finally install the cf CLI
sudo apt-get update
sudo apt-get install cf-cli

[georgi-bozhinov]

I had the same error and it turns out virtualization wasn't enabled on my machine. The issue was fixed by enabling it.

[karizma987]

@georgi-bozhinov i check my system, virtualisation is already enabled. i tried to do the whole process again. still geting the same error.
cf dev start: unable to find VM IP address from '/var/lib/libvirt/dnsmasq/virbr0.status'

[aemengo]

@karizma987 Is that file present? What are the contents of /var/lib/libvirt/dnsmasq/virbr0.status. Is there any file present at this directory: /var/lib/libvirt/dnsmasq/?

[some-ibmer]

Had the same problem as @georgi-bozhinov where virtualization was not enabled on the machine. Works now that it is enabled.

[karizma987]

@aemengo i check the file in var/lib/libvirt/dnsmasq/virbr0.status
the file is present but its empty. when i open it is shows square brackets like this
[

]

and no other content.

[karizma987]

@eddie-at-ibm i use the following command to check whether virtualization is enabled or not.

sudo modprobe msr
sudo rdmsr 0x3a
Values 3 and 5 mean it's activated.
and my system is returning 5 and even checked the system setup setting virtualization is enabled.
and the problem still persist.

@karizma987

1. Does the following command return anything? ps aux | grep linuxkit

2. Are there any files that can be found in: ~/.cfdev/log?

[karizma987]

@aemengo ps aux | grep linuxkit gives the below output

inside ~/.cfdev/log

linuxkit.log is present.

one new thing happened, i tried reinstalling again the cf dev.... but this time the error i got is this:-

Creating the VM...
Starting the VM...
Fetching VM Address...
FAILED
cf dev start: unexpected end of JSON input

now i don't know whether the previous error is rectified or i got a new error in addition. trying finding the solution for this error now. will update soon further about the progress.

[aemengo]

What are the last few lines of the linuxkit.log file?

[karizma987]

@aemengo can you tell where to find this linuxkit.log file? i used the terminal to see the content of cfdev/log but not able to see the content of linuxkit.log

[aemengo]

Can you perform the following and tell me the output?

$ tail -n 30 ~/.cfdev/log/linuxkit.log
