similar to: Storage Pools & nodedev-create specific scsi_host#?

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? ========================================== NPIV in libvirt NPIV (N_Port ID Virtualization) is a Fibre Channel technology to share a single physical Fibre Channel HBA with multiple virtual

Before posting it to WIKI or somewhere, I want to see if there is any suggestions on it, or if I missed something. ============================================ How to use NPIV in libvirt I planned to wrote a document about how to use NPIV in libvirt after more features are supported, but it looks like I can't wait till then, got lots lots of questions from both the

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

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

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:

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: # ll /sys/bus/scsi/devices/7:* lrwxrwxrwx 1 root root 0 Feb 8 12:58 /sys/bus/scsi/devices/7:0:0:0 -> ../../../devices/pci0000:00/0000:00:03.0/0000:08:00.1/host7/rport-7:0-0/target7:0:0/7:0:0:0 lrwxrwxrwx 1 root root 0 Feb 8 12:58

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:

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, 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

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
