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'/>

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

Re: Oracle RAC in libvirt+KVM environment
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?

Re: Oracle RAC in libvirt+KVM environment
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:

It's this means that the scsi passthrough windows driver does not

non-blocking virtConnectOpen
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?
Thanks

dumpxml and edit the vm xml are not match.
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.

Re: Oracle RAC in libvirt+KVM environment
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

Re: Oracle RAC in libvirt+KVM environment
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.

I tried to set the disk as raw format, and retried the setup process,

I am also confused. You need to understand the limitations that the
clustering software is putting.

Re: Oracle RAC in libvirt+KVM environment
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.

Re: Oracle RAC in libvirt+KVM environment
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

Re: Oracle RAC in libvirt+KVM environment
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?
