CentOS

Did you have a look at:

https://github.com/Bumblebee-Project/Bu ... leshooting

Fixed it. I removed all the virtio hardware from the virtual machine.

Did some more testing, looks like Xen kernel is broken.

Those modules exist. Also all the required scsi modules as well.

I wanted to do some testing with xen. I created a vm with centos 6.7, made sure VMX flags are passed to the VM and used e1000 en SATA disk instead of virtio. The VM has 2 cpu's and 4 gb ram.
I get the following error: FATAL: Module scsi_wait_scan not found

Who can help me with this issue?

You will have to check the x11 logs why you have these problems. Check bumblebeed service, etc.

Why did you uninstall glamour x11 package?
The bumblebee package will unconfigure glamour for you.

Please follow the instructions exactly.

I switched to Fedora, i just need the newer packages (eclipse, devassist etc)
I now can use Nouveau Optimus, it isn't perfect yet, but it works out of the box and looks to get better after the first update.

Thanks, i just signed up and will have a look at the mailinglist to see how it all works.

Any news about the SIG for packaging SCL?
Wouldn't mind to participate, because i like the stability of Centos compared to Fedora, would be nice to add some newer packages, like the development tools etc.
