Subject CloudStack + KVM(Ubuntu 12.04, Libvirt 1.0.2) + Ceph [Seeking Help]
Date Wed, 16 Oct 2013 23:22:06 GMT
Hi, 

I have gotten so close to have Ceph work in my cloud but I have reached a roadblock. Any help
would be greatly appreciated. I know this is not actually a CloudStack issue at this point,
but I also know several ACS users have tried Ceph. 

I receive the following error when trying to get KVM to run a VM with an RBD volume: 

Libvirtd.log:

Thank you if anyone can help :)
