vhba and storage pool creation
Hi!
Got a couple of storage questions here.
I'm a storage guy, running a new project, and just started with libvirt, but have been using qemu/kvm on other platforms before, as well as oVirt.
So, my questions here:
I started with creating a vhba, and that went fine, I could see it on the storage side logging in to the target with its wwn.
My next step would be to make it persistent, and

Getting "unknown device type" when attaching NPIV (vHBA) to vm
Hi,
I'm trying to attach a host FC HBA to VM (NPIV).
Running ovirt 3.5 on CentOS 6.7, libvirt-0.10.2-46.el6_6.6.x86_64, I created vHBA using nodedev-create command - see below HBA and vHBA.
I wrote a vdsm hook which appends the vHBA xml stanza to the devices xml element but the vm start starts without the vHBA device.
Also, when trying to attach the device manually as a live device - I get:

Question about vport operation for FC HBA
Hi,
When I want to use NPIV for a FC HBA in my Linux machine, I got the
below error msg in virsh:
virsh # nodedev-create /home/kvm/vHBA.xml
error: Failed to create node device from /home/kvm/vHBA.xml
error: internal error Parent device scsi_host20 is not capable of vport
operations
I checked the /sys/class folder for my HBA device that I want to use its
NPIV feature, it's there:

Thank you for your reply,
I'm still getting hard time to attach the hostdev, I couldn't make it work out of the doc.
I took the address details from:

Re: attaching storage pool error
Hi again!
Need to add here, since I been investigating a bit further, that it seems to be possible to add an NPIV vhba to the guest, using vdsm hooks. I've seen the reference to "host device assignments", which Dan pointed me too, but I didn't really understand the meaning of it at that moment.
It would be interesting to hear from someone that have been doing it, how it would

Hi!
Report from my multipath tests today.
My test virtual machine, that runs from an NPIV pool, is not able to use multipath.
When I pulled the cable from one of the targets, it crashed.
But, strangely, it could boot up again on that other path, that it just crashed on.
That tells me it can use both paths, and is not limited to one of them only, but because the multipath layer isn't

Doc v2: How to use NPIV in libvirt
Thanks for John Ferlan's lots of internal feedbacks, I believe it's more
readable, and better orgnized now. Should we create a page for it
under http://libvirt.org/deployment.html or add it in WIKI?

Hi, John, and thank you!
This was a very thorough and welcome response, I was wondering where all the storage guys were...
I will get back to you with more details later, specifically about multipath, since this needs to be investigated thoroughly.
I have, with trial and error method, during the elapsed time, been able to attach the NPIV pool LUN to a virtio-scsi controller, and it seems it

Haha, I wondered for a minute whether I should bring up that bug...
We've seen pretty nasty crashes due to it and had to work around
it.....
One of my recent work has also uncovered another (I believe) invalid
handling of returns_twice functions....

NPIV + KVM
Is this possible:
I would like to have a VM use a FC LUN exported to a virtual wwn (using
NPIV) as its primary disk.
I was thinking there might be a mechanism to say VM, boot using a LUN
with this vwwn as your primary disk?
Thanks in advance.

NPIV storage pools do not map to same LUN units across hosts.

Topic: Virtual machine configuration change to use vHBA LUN
There is a NPIV storage pool defined on two hosts and pool contains a
total of 8 volumes, allocated from a storage device.

NPIV setup?
I'm missing something.
The purpose of NPIV (as I understand it) is to give a guest OS an HBA that
it can scan, play with new luns, etc all without making changes to the
physical server(s) the guest is living in currently.
However, I can't find a way to either have the guest's XML config create
the HBA or for the physical server to successfully GIVE the HBA to the
guest. I can give

FNIC nested PVM
I''m trying to do nested XEN to give some of my colleagues a play area to
work in, and it seems to work - but not quite.
I can build the nested environment (using OVM, and I have to step back to
OVM3.2.2 to allow me to do PCI passthrough), but as soon as I start up a VM
with a phys device passed through, the first layer loses all connectivity to
the SAN.
