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

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

Release of libvirt-0.8.2
Following Dan advice, I decided to not wait for more patches and push the current git head as the release. Let's plan to have another release by this month end with the QEmu debugging and hacking APIs. The release is available as usual at ftp://libvirt.org/libvirt Quite a lot of bug fixes during the two months since 0.8.1, and a few new feature. It also tagged more commits as being

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

multipath
I have inherited a system set up with multipath, which is not something I have seen before so I could use some advice The system is a Dell R420 with 2 LSI SAS2008 HBAs, 4 internal disks, and a MD3200 storage array attached via SAS cables. Oh and CentOS 6 lsblk shows the following: NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sdd 8:48 0 931.5G 0 disk ??sdd1

Multipath w/ iscsi
I have several CentOS 6 boxes that mount iscsi based luns and use mpath. They all had problems shutting down as a result of unused maps not getting flushed as the system halted. After examining the init scripts, netfs, iscsi and multipathd all had the correct order but mpath failed to flush these maps and the system waited indefinitely. In the meantime I hacked this by adding a `/sbin/multipath

[PATCH] RFC: v2v: add and use libvirt connection objects
Enhance the Libvirt_utils module with libvirt connection objects, and read-only and read-writen open functions for them; adapt the rest of the mini-binding to use these objects, instead of opening + closing libvirt connections every time. This has different improvements: a) a libvirt connection is reused for different API calls, improving the communication with remote (input) servers b)

Unable to start LXC on Gentoo w/ libvirt 1.0.4 or 1.0.5. 1.0.3 works
Hello. I use libvirtd on my Gentoo development system to manage both QEMU and LXC. When 1.0.3 came out, I updated to it from 1.0.3-r2, but 1.0.4 failed to start my LXC containers. I did not research the issue at the time, so I revert to 1.0.3-r2. Today I updated to 1.0.5 and my LXC containers still fail to start. I have not changed my domain XML at all. I am looking for suggestions on

[PATCH v4 3/7] v2v: switch to ocaml-libvirt
Currently virt-v2v has few custom C-based functions for libvirt operations, which are limited in what they do, and there is a lot of duplicated code. Instead, switch to ocaml-libvirt for all the libvirt interaction currently done by the Libvirt_utils module. This has few advantages: - each input & output module now opens a libvirt connection only once, only when needed - no need to pass

Multipath-root (mpath) problems with CentOS 5
Hi list! I have a server with dual port Qlogic iSCSI HBA. I set up the same LUN for both ports, and boot the CentOS installer with "linux mpath". Installer detects multipathing fine, and creates mpath0 device for root disk. Installation goes fine, and the system boots up and works fine after the install from the multipath root device. After install the setup is like this: LUN 0 on

libvirt v1.0.2 fails to boot LXC container, but v1.0.0 works
Hello. tl;dr = v1.0.0 can boot my LXC containers, v.1.0.1 and v.1.0.2 fails. Paraphrased error message: "lxcContainerMountProcFuse:616 : Failed to mount ..../meminfo" I'd like to know if my host is misconfigured, or my domains, or ... why 1.0.2 and 1.0.1 are not working for me. I've been using libvirt for a while to manage QEMU instances. I have experimented with lxc.

Libvirt with multipath devices and/or FC on NPIV
Hello, I am trying to find out a best practice for a specific scenario. First of all I would like to know what is the proper way to set up multipath, who should care about it the host or the guest. Right now I have a setup where I have one multipath which sets my host to boot from FC SAN. I have another multipathed LUN in the host which is essentially a dm which I attached to a guest, however
