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 all, I'm unable to upgrade my Dom-0 from CentOS 7.5 to CentOS 7.6 with the sigvirt centos-xen-48 repository enabled and Xen components enabled. It breaks down to down to the fact that 7.6 has a newer version of libvirt included (4.5), while the Xen repository's packages are build against 4.1 version of libvirt. I also tried to enable the libvirt-latest repository, but that does not

Hello everyone, Current host build is RHEL 6.2, soon to be upgrading. I'm in the process of mapping out a KVM/RHEV topology. I have questions about the landscape of storage pools and the instantiation of specific scsi_host IDs using virsh nodedev-create and some magic XML definitions. I'm grouping these questions together because the answer to one may impact the other. High-level

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

Just to answer my own question, I solved this by installing yum-plugin-priorities and setting priority=10 to centos-virt-xen-48 repository. Yum doesn't consider the libvirt packages from CentOS base/updates anymore after this.

Anyone have an idea of what may have happened or how to fix? I'm only seeing this issue after the OS update to CentOS 7.3.

I have a Dell T430 with CentOS 7 kernel release: 3.18.41-20.el7.x86_64 and xen_version : 4.6.3-3.el7 I am doing an update of my server, but it fails:- yum update ================================================================================= Error: Package: libvirt-daemon-driver-libxl-1.3.0-1.el7.x86_64 (@centos-virt-xen) Requires: libvirt-daemon = 1.3.0-1.el7 Removing:

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:

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

PJ My server is critical to me, but not the public, fortunately. I can take it down as I suggested, but am a bit reluctant to do so until I have heard more opinions. Presumably your system update failed using your script, so it will probably fail for me if I copy it. I will keep a copy anyway. ----- Original Message ----- > From: "PJ Welsh" <pjwelsh at gmail.com> > To:

I'v also got this issue when trying to update my CentOS 7.3 systems. I did see a new user request that mentioned beginning to help with libvrit 2.0 and/or 2.5 updates. Just not sure what to do in the short term? Any hints/help would be appreciated: Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.cmich.edu * elrepo: mirrors.netix.net * epel:

I am still waiting in hope someone will have an idea on what to do. Perhaps I should do this:- boot into a normal kernel uninstall centos-virt update the system reinstall centos-virt What do you think?

Dear Jean-Marc, Thank you for replying. I Installed CentOS 7 and centos-virt from the normal repos (CentOS-Xen) in December 2015 and have not had to build anything. I am running CentOS 7, not sure if it has automatically updated itself to 7.3, so I would expect the updates to come from the repo, and not need building from source.

As libvirt from Xen is 1.3.0 and libvirt from CentOS 7.3 is now 2.0.0, libvirt from Xen has to be rebuild to upgrade the new libvirt 2.0.0 See my previous post : https://lists.centos.org/pipermail/centos-virt/2016-November/005255.html I've done it for my own repo : https://copr.fedorainfracloud.org/coprs/jmliger/virt7-upstream/ Regards, Jean-Marc Le 30/12/2016 ? 17:56, Francis The

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

Jiri Denemark has already proposed to help rebuild libvirt for CentOS-Xen but I don't know if he got all that is need to do so ? Maybe I could help also, but I would have to learn the Centos build system first.

Hi, I am using the libvirt 1.0.6 with the patch applied: http://libvirt.org/git/?p=libvirt.git;a=commitdiff;h=371c155 The problem I encountered is, with virsh comand 'nodedev-create /home/kvm/vHBA.xml', the vHBA can be generated as expected on the host, but error msg will show in the virsh shell: libvirt: Node Device Driver error : Node device not found I try to find the reason with
