Hi @all, I am evaluating KVM for our Cloudstack installation. We are using XenServer at the moment. We want to use shared storage so we can do live migration of VMs. For our KVM hosts I am using CentOS7 with standard kernel as OS and for shared storage I am evaluating ScaleIO. KVM and ScaleIO installation is working great and I can map a volume to all KVM hosts. I end up with a device (dev/scinia) of block storage on all KVM hosts.
As far as I understand I need a cluster filesystem on this device so I can use it on all KVM hosts simultaneously. So my options are ocfs2, gfs2 and clvm. As documented clvm is not supported by Cloudstack and therefore not really an option. I found this shapeblue howto (http://www.shapeblue.com/installing-and-configuring-an-ocfs2-clustered-file-system/) for ocfs2, but this is for CentOS6 and I am unable to find a working ocfs2 module for CentOS7 standard kernel. So my question is how are you implementing shared storage with KVM hosts in your Cloudstack installation if it is not NFS? Thx for your help!
