Caveat: I know nothing in particular about Oracle RAC, but... Assuming that RAC uses something like SCSI reservations in order to share the disk, I would guess it doesn't like the disk being on the IDE

I have tryied change the disk bus to SCSI, add a SCSI controller whose model is virtio-scsi, still can't setup the RAC instance. I tried to use windows 2008 Failover Cluster feature to setup a a Failover Cluster instead, and I can't find any cluster disk to share between two nodes. So when Failover Cluster is setup, I can't add any Cluster disk to the Failover Cluster. Have I missed

Anybody have idea on it? I tried to set the disk as raw format, and retried the setup process, but still can't get through.

Thanks, the whole iSCSI LUN have been passed to the VM. But I test it with scsicmd, and found that the driver may be not support SPC-3, but if i use this by microsoft iscsi initiator, I can pass all the scsi3_test tests. Tool can be found here: http://www.symantec.com/business/support/index?page=content&id=TECH72086 It's this means that the scsi passthrough windows driver does not

Thanks. I have read the link you provide, there is another link which tells me to pass a NPIV discovery lun as a disk, this is seen as a local direct access disk in windows. RAC and Failure Cluster both consider this pass through disk as local disk, not a share disk, and the setup process failed. Hyper-v provides a virtual Fiber Channel implementation, so I wondering if kvm has the same solution

Hi all, I found a article about Hyper-V virtual Fiber Channel, I think this will make Failover Cluster work if KVM has the same feature. http://technet.microsoft.com/en-us/library/hh831413.aspx Hyper-V uses NPIV for virtual Fiber Channel, I have read some article about KVM NPIV, but how can I config it with libvirt? Any body can show me some example? On Wed, Aug 14, 2013 at 2:33 PM, Timon Wang

Hi all, does anybody know how to do non-blocking virtConnectOpen? does libvirt support it or not cause I can't find any document about it? or should I need create a thread to do it?

I use vnc with password for the vm graphics, it works well. When I want to dump the xml of the vm, I found that the dumped xml does not contains the password properties in the graphics node. But when I use virsh edit to check the xml of the vm, I found the password is displayed. It's it a bug or it's just what libvirt designed to perform. -- Focus on: Server Vitualization, Network

Yes, SCSI bus likes pass through a shared LUN to the vm, and I am using a shared LUN for 'share' purpose. I found a post that vmware use lsilogic bus for the shared disk, but my qemu/kvm version can't support lsilogic bus. I'm tring to update qemu/kvm version for lsilogic bus support.

Thanks, i have tried virtio-scsi and LSI SCSI controller, by using a local file or a LUN as disk. Both raw and qcow2 disk format are be verified, but no way to make windows Failover Cluster and Oracle RAC work correctly. Actually, Oracle RAC and Windows Failover Cluster needs "share" storage like iscsi disk and fc disk to work correctly. In iscsi situation, we can use ip network for

Thanks Nicholas. I found that scsicmd can't pass all the scsi3_test but the result of sg_inq is the same as it in the host. I am absolutely confused about this situation. Am I missed some information about it? On Wed, Aug 21, 2013 at 5:40 PM, Nicholas A.
