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

I am using NFS over brtfs (vanilla 3.8.5) for heavy CoW to clone virtual disks with sizes 20-50GB. It worked OK for a couple of days, but yesterday it crashed. Reboot fixed the problem and I do not see any data corruption. I have a couple of different kdumps, I will include one as text and attach the other ones. I am using Fedora 18 with vanilla 3.8.5. The filesystem is created over a SAN volume

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

I was looking up on iSCSI in preparation and became aware that there are different iSCSI software/drivers/whatever-is-the-correct-term available. e.g. IET http://iscsitarget.sourceforge.net/ SCST http://scst.sourceforge.net/ STGT http://stgt.berlios.de/ LIO http://linux-iscsi.org/ Based on what I can see, it seems to be STGT because the site provides a link to Redhat advisory which seems to

Hi, hope the week has started out well for everyone. This report may be in the FWIW department since there may be a fundamental reason why this doesn''t work. We elected to report this to the Xen community since we thought any behavior which corrupted disk images needed to at least be reported. We are maintaining the Xen-SAN release which provides hotplug functionality to allow Xen

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 all, Last week we had 2 times an "uncorrectable ecc memory error" crash on our server on the same memory module. After removing the faulty module and restarting the server, everything was working again. However, yesterday we had a soft lockup and had to restart the server again. No warning or ecc error this time. Everything is working now, but we want to avoid this in the future

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

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 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

As a CentOs newbie, I'm not sure, will we still have CentOS 7.1 which derive from RHEL 7.1? or this is the new naming conversion for CentOS 7.
