[libvirt-users] Oracle RAC in libvirt+KVM environment

We wan't to setup two Oracle instance and make RAC work on them. Both VM are setup based on libvirt + KVM, we use a lvm lun which formated in qcow2 format and set the shareable properties in the disk driver like this: <disk type='block' device='disk'> <driver name='qemu' type='qcow2' cache='none'/> <source dev='/dev/81035c32-d2e4-4aaf-82fa-3e76ae587586/ca18f6a5-7c98-46ea-b562-9424e68a52f3'/> <target dev='hda' bus='ide'/> <shareable/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> But when we use it as shared data disk like we use iscsi/FC disk for shared data disk, the disk can't be recognized as a share disk, and RAC can't be setup in the environment. Any body can give me some guild on this? I am wondering shareable in the libvirt config really makes the disk shareable? How can I setup the RAC environment in this situable? I found that vmware and vbox can do this according to a blog post, I am wondering if kvm has this ability to make a disk really shareable. -- Focus on: Server Vitualization, Network security,Scanner,NodeJS,JAVA,WWW Blog: http://www.nohouse.net
