Openstack using DevStack - Failed to fetch cdrom

Hi,

While going over all the configuration needed with devstack for open stack and during the installation - after running ./stack.sh i received an error
"failed to fetch cdrom ...."

To solve this, go into /etc/apt
do 'sudo nano sources.list' and remove by using '#" the cd rom line.

Then start again the ./stack.sh and it will work

you just removed / disabled the cd rom



Hoped i helped,

Fedora 22 VirtualBox

Hi,

I have installed the latest fedora 22 and from some reason VirtualBox gave me tons of errors.

Looked all over the place and didn't find any good solution till now. So i wanted to share this with you to save you time, hopefully that you are seeing before all the searches i already did.

This is the required things to do:
This was my error

WARNING: The vboxdrv kernel module is not loaded. Either there is no module

         available for the current kernel (4.1.6-201.fc22.x86_64) or it failed to

         load. Please recompile the kernel module and install it by

           sudo /etc/init.d/vboxdrv setup

         You will not be able to start VMs until this problem is fixed.

 First , try to run this, with or without sudo
"/etc/init.d/vboxdrv setup"

if it went ok -> you are all good, probably virtualbox will run ok for you, for me it didn't helped.

If it didn't went ok, go over here :
I got this error

Stopping VirtualBox kernel modules                         [  OK  ]

Recompiling VirtualBox kernel modules/etc/init.d/vboxdrv: line 335: /var/log/vbox-install.log: Permission denied

                                                           [FAILED]

  (Look at /var/log/vbox-install.log to find out what went wrong)

So i did as they say : "cat /var/log/vbox-install.log"
And got this:

Makefile:185: *** Error: unable to find the sources of your current Linux kernel. Specify KERN_DIR=<directory> and run Make again.  Stop.

So i did the following:
"sudo usermod -a -G vboxusers username" (you will replace username with your name of the user)
Then
"su -"
Then
" KERN_DIR=/usr/src/kernels/username" (replace username with your name of the user)
"export KERN_DIR"
"dnf install open-vm-tools"
"dnf -y install kernel-devel kernel-headers"
"sudo /etc/init.d/vboxdrv setup" -> this should be running ok now
You should receive something like me

Stopping VirtualBox kernel modules                         [  OK  ]

Recompiling VirtualBox kernel modules                      [  OK  ]

Starting VirtualBox kernel modules                         [  OK  ]

Good luck and hopefully that i helped a bit,
