Can't run cfdev on Linux Mint 19.1

wjbaird commented 5 years ago

Hi there,

I've followed the instructions on the main cfdev page, and additionally followed the instructions to set up kvm as recommended here: https://lists.cloudfoundry.org/g/cf-dev/topic/31075762 - but when I run "cf dev start", I get the following:

$ cf dev start
Downloading Resources...
Progress: |====================>| 100.0%
Setting State...
Error: argument "virbr0" is wrong: Device does not exist

Cannot find device "virbr0"
Creating the VM...
Starting the VM...
Fetching VM Address...

cf dev start: exit status 1

Any suggestions?

The labels on this github issue will be updated when the story is started.

virbr0 is the default network adapter installed by libvirt. Is that installed on your system as written in README?

Also please understand that our Linux configuration has only been tested on Ubuntu.

Try virsh net-list to see if default network is on the list:

# virsh net-list
 Name                 State      Autostart     Persistent
----------------------------------------------------------
 default              active     yes           yes
 docker-machines      active     yes           yes
 vagrant-libvirt      active     yes           yes

when it's not active try:

virsh net-start default
virsh net-autostart default

I assume that libvirtd daemon is already running:

service libvirtd start

@aemengo - I did install libvirt

dpkg -l libvirt*

Linux Mint is based on Ubuntu - 19.1 is based on Ubuntu Bionic, so I'd be a bit surprised if there were major differences. @alexo134 - libvirtd seems to be running:

service libvirtd status
● libvirtd.service - Virtualization daemon

but virsh net-start default gives me an error:

error: Failed to start network default
error: internal error: Failed to initialize a valid firewall backend

Whoops - sorry, I'm a github noob - I assumed that using the 'code' mode would preserve formatting, but apparently I messed something up... I've attached a text file with the output from the previous comment in what will hopefully be a more readable form comments.txt

wjbaird commented 5 years ago

OK - the error on 'virsh net-start default' led me to this page: https://superuser.com/questions/1063240/libvirt-failed-to-initialize-a-valid-firewall-backend which suggested also installing ebtables, firewalld and dnsmasq - I did that, restarted libvirttd and now I'm at least getting further along - it's in the processes of deploying CF...

I'll leave this open in case you want to use it to track any doc updates about needing additional packages, but feel free to close if you like...

Thanks for your help!

aemengo commented 5 years ago

Thank you so much for documenting the steps you took! This is going to be a big value for anyone who encounters this in the future.

Since you were able to get passed the specific error message that the issue was about, I'll close this to keep it succinct.
