centos 7 kernel 693 extremely slow boot on ovirt version 4.1.5.2-1.el7.centos
by Charles Kozler 16 Sep '17

16 Sep '17

I have tried this multiple times I imported glance image latest centos 7 as a template. Made a VM from it and rebooted it multiple times testing some apps. Reboot was always 30 seconds or less I did a full yum update and then reboot on reboot I am hung up at "[drm] initalized qxl 0.1.0 20120117 for 000:00:02.0 on minor 0" for between 3-5 minutes (varies, but usually averages there) https://i.imgur.com/ZAhf4je.png for reference QXL I know is the console. I tried setting it to VGA and it hung on about the same part except it doesnt reference QXL, it references another device driver. I am guessing there is some issue with the display drivers? Not really sure what to say about this...is this a KVM issue? A centos 7 kernel issue? Or is ovirt booting the VM via KVM with a parameter that is new-ish and causing some conflict with new kernel? or did something update in the image that I wasnt aware that is causing slow boot now? Host(s) kernel is 3.10.0-514.26.2.el7.x86_64

Disk image upload via CLI?
by Matthias Leopold 15 Sep '17

15 Sep '17

Hi, is there a way to upload disk images (not OVF files, not ISO files) to oVirt storage domains via CLI? I need to upload a 800GB file and this is not really comfortable via browser. I looked at ovirt-shell and https://www.ovirt.org/develop/release-management/features/storage/image-upl…, but i didn't find an option in either of them. thx matthias

Recommended gluster setup
by Abi Askushi 15 Sep '17

15 Sep '17

Hi all, I see in the ovirt guides that a gluster volume replica 3 with 1 arbiter is recommended. Why not simple replica 3? Is it due to the higher replication data that would cause performance issues? What I am observing is that a VM running on the server which has the arbiter brick has slower read performance then when the same VM runs on another server with a normal brick. Has anyone observed this? Is it because the arbiter does not have the real data on it? Thanx, Alex

Different link speeds in LACP LAG?
by Chris Adams 15 Sep '17

15 Sep '17

I have a small oVirt setup for one customer, with two servers each connected to a two-switch stack with 1G links. Now the customer would like to upgrade the server links to 10G. My question is this: can I add a 10G NIC and do this with minimal "fuss" by just adding the 10G links to the same LAG, then removing the 1G links? I would have the host in maintenance mode no matter what. I haven't checked the switch to see if it'll support that yet, figured I'd start on the oVirt side. -- Chris Adams <cma(a)cmadams.net>

V4.1 questions
by Colin Coe 14 Sep '17

14 Sep '17

Hi all We're in the process of upgrading from RHEV 3.5 to 4.1.5 and I have a couple of questions. RHV 4.1.5 takes between 10-15 minutes to become usable after a service restart, is this expected or is something wrong with our environment? The webUI seems to timeout and go back to the logon page after a very short time. Can this behavior be changed? Lastly, the RH318 course book states that to upgrade a RHEV-H node via RHEV-M, you need to install the "rhev-hypervisor7" package on the RHEV-M node. Is this still correct? Thanks CC

oVirt node with SHE on FC
by Gianluca Cecchi 14 Sep '17

14 Sep '17

Hello, it is not clear to me the exact workflow in case of testing what in object. For sure first step is to install base node from iso. NGN has no more read only filesystem. Does this mean that I have to set up eg multipath for FC LUNs (engine and data domain) before running the engine setup via cockpit? Or when I specify FC in type of storage domain it would ask and setup automatically multipath for me? Are the ovirt repos already setup when I have installed from the iso or do I have to install ovirt-release-xx rpm? In another enviroment with block based storage domains (iSCSI) and an external engine and full CentOS hypervisors I customized vdsm creating a file /etc/vdsm/vdsm.conf.d named 50_thin_block_extension_rules.conf using volume_utilization_percent = 25 volume_utilization_chunk_mb = 4096 Can I make these sort of customization in NGN without any persist command, because the file system is read write now or should I manage from cockpit or other tools instead? I'm exploring situations where NGN could be suitable better than full CentOS OS for hypervisors and I would like to know clearly advantages and limits. Thanks in advance Gianluca

Question: Where does Ovirt stores VM snapshots?
by Shashwat shagun 14 Sep '17

14 Sep '17

Hi, I’m new to Ovirt, I just wanted to know where does Ovirt stores VM snapshots (On the hosts?) and It stores the VM virtual hard drives on hosts right? Because wouldn’t it’ll be slow if they stores it on a Network drive? P.S sorry for my bad English, English is not my first language Regards, Shashwat Shagun me(a)shashwat.tech

why force bond* naming?
by Charles Kozler 13 Sep '17

13 Sep '17

Hello - I had setup my server somewhat before installing ovirt. I left em1 alone for the ovirtmgmt but I had bonded two NICs on a separate card and named it storage0 and storage1 accordingly. Everything setup fine and when I went to add more networks for em3+em4 in LACP named bond0, the web UI would not let me proceed because my two NICs named storage0 and storage1. It didnt say directly it was those but it said it needed "bond" in the name followed by a number. I shut everything down and renamed them bond100 and bond101 and all was well However, I cant stop and think that I was not trying to set those NICs (storage0/1) up in ovirt so why would ovirt UI care about NICs in the server that it wasnt even responsible for managing nor I had any modifications to from the UI? I get forcing it when you're adding through to UI but making the UI force the user to use bond* for all of their NICs doesnt seem right Thoughts?
