clean up a fc lun to reuse it
by Nathanaël Blanchet 03 Oct '18

03 Oct '18

Hi all, I tried to install the Hosted-Engine on a FC lun, and the first time, it failed at the end because of a sanlock issue. So I fixed it and the re-deoployed from scratch until this new issue [ ERROR ] Error: Fault reason is "Operation Failed". Fault detail is "[Physical device initialization failed. Please check that the device is empty and accessible by the host.]". HTTP response code is 400. Before, I found that the lun [2] was used: [ INFO ] ok: [localhost] The following luns have been found on the requested target: [1] 36006016039a142001792ac5b1b9e513a 1024GiB DGC VRAID status: free, paths: 8 active [2] 36006016039a142006755b25b7505d26b 100GiB DGC VRAID status: used, paths: 8 active So it was the good explanation for the failure. Following the admin guide, I cleaned up the lun using |# dd if=/dev/zero of=/dev/mapper/||36006016039a142006755b25b7505d26b bs=1M count=200 oflag=direct| And re-deployed it until it complains the device was not empty despite of before. The script still reported that the status of the lun was "used" Finally, I rebooted the host, and that time the script considered the lun status as free. So there is somewhere a bit of code into the ansible script that keeps the old status of the lun before dd, until rebooting. Is there an other way to refresh the lun status after dd ?

[OT] transferring kvm raw mage from filesystem to lvm based
by Gianluca Cecchi 02 Oct '18

02 Oct '18

Hello, I have a windows 7 VM that is composed by a raw disk on filesystem on Fedora 28. I would like to transfer this VM to another environment, always based on same version of Fedora 28, but where the storage is configured in virt-manager as lvm based, so similar to what happens in oVirt block based storage domains. I'm trying to figure how to transfer the image. I presume I can create a new LV and then leave some bytes for the LVM header into the created LV and then make a sort of dd with offset? Anyone has any hint? Thanks in advance, Gianluca

iSCSI multipath with Dell Compellent
by Bernhard Dick 02 Oct '18

02 Oct '18

Hi, I'm trying to achieve iSCSI multipathing with an Dell Compellent SC4020 array. As the Dell Array does not work as an ALUA system it displays available LUNs only on the currently active system (here is a good description that I found: https://niktips.wordpress.com/2016/05/16/dell-compellent-is-not-an-alua-sto… ). As a result I cannot add the currently non-active controller to an iSCSI-Bond (as it does not present the LUNs to oVirt) and so the path to the second controller will not be up. Is there any way to solve this? Regards Bernhard

Change network interface for hosted engine iSCSI connection
by Bernhard Dick 02 Oct '18

02 Oct '18

Hi, after I changed the network configuration of one of my hosted engine hosts in oVirt I am no longer able to run the ha-daemon on the host. When I run hosted-engine --connect-storage on this host I get the following error: vdsm.client.TimeoutError: Request StoragePool.connectStorageServer with args {'connectionParams': [{'netIfaceName': 'ens1f1', 'port': '3260', 'connection': '192.168.1.1', 'iqn': 'iqn.2002-03.com.compellent:5000 d...', 'user': '', 'tpgt': '0', 'ifaceName': 'ens1f1', 'password': '', 'id': 'cd5fa13f-fbb7-4cc6-a094-4b280dc7b514'}], 'storagepoolID': '00000000-0000-0000-0000-000000000000', 'domainType': 3} timed out after 60 seconds ens1f1 is the network card that has been used earlier for iSCSI, now it should connect via ens1f0. Is there a way to update this configuration for the host? Regards Bernhard

Trouble to update the ovirt hosts (and solution)
by Arman Khalatyan 02 Oct '18

02 Oct '18

Current cocpit packages are conflicting, which is preventing the host update: .... Transaction check error: file /usr/share/cockpit/networkmanager/manifest.json from install of cockpit-system-176-2.el7.centos.noarch conflicts with file from package cockpit-networkmanager-172-1.el7.noarch file /usr/share/cockpit/networkmanager/po.ca.js.gz from install of cockpit-system-176-2.el7.centos.noarch conflicts with file from package cockpit-networkmanager-172-1.el7.noarch .... Looks like a current packaging of cocpit is wrong, it doesn't upgrade existing version. To solve it simply: yum remove cockpit-networkmanager-172-1.el7.noarch yum clean ;yum update all fixed. arman.

clarification needed on power management options
by g.vasilopoulos＠uoc.gr 01 Oct '18

01 Oct '18

I would like some clarification on MinFreeMemoryForUnderUtilized and MaxFreeMemoryForOverUtilized. How does that work? it seems the names should be oposite ? so if I have hosts with 64GB ram and I want to consider them over utilized at 48GB used and under utilized at 12GB used, should I set MinFreeMemoryForUnderUtilized=12GB MaxFreeMemoryForOverUtilized=48GB ? is this correct ? Also If ihave hyperconverged setup with 3 hosts having a replica3 storage for the engine and I disable policy management on these hosts, will these hosts be part of the overall utilization regardless if the engine can shut them down ?

liveliness check fails on one host
by g.vasilopoulos＠uoc.gr 01 Oct '18

01 Oct '18

I have an ovirt installation (4.2.6), and I have come accross this issue: Hosted engine can migrate to a certain host say host5. Admin portal is working fine, everything is working fine AFAIK but hosted-engne --vm-status shows "failed livelines check", when engine is on that host, so after a while the engine migrates somewhere else, it not a terrible problem, but it is annoying and I would like to know why is this happening, and if there is a way to fix it On every other host in the cluster this problem does not exists. firewall rules are exactly the same on hosts (in fact they are copied) . Any places to look at? Thank you

Suggestion: Addition of a one-off PXE boot option in the "Edit Virtual Machine > Boot Options" section
by Zach Dzielinski 30 Sep '18

30 Sep '18

My current usage of oVirt requires me to switch the boot priorities for virtual machines from hard disk to pxe fairly often. It would be nice to see an option added in that would set a one-off pxe boot for virtual machines, reverting back to the original boot priorities after restart. This would save some time when dealing with multiple machines, by eliminating the need to switch them to pxe and then back to their previous boot options in the middle of their boot process.

Networking in oVirt
by sinan＠turka.nl 30 Sep '18

30 Sep '18

Hi all, Today I have installed oVirt 4.2 on a single machine (self hosted engine). My server has 6 physical adapters, but only 1 has an active uplink (enp2s0f0). The server is directly connected to the internet. The installation of oVirt created the following interfaces: - br-int - ovirtmgmt [IP configured: inet 85.17.x.x] - virbr0 [IP configured: inet 192.168.122.1] - virbr0-nic - vnet0 The hosted-engine is attached to ovirtmgmt and got IP 192.168.122.76 assigned. The hosted-engine does have access to the internet. The logical network ovirtmgmt is assigned to the physical interface enp2s0f0 when I check this via the oVirt webgui. I have 2 questions. Q1: I would like to achieve the following: - Create a new network, call it vm_network. - Create VM's and attach them to the vm_network. - These VM's should able to access the internet. Is this possible, if so, how do I achieve this? Q2: When my first question is answered and I have VM's running, some of the VM's I would like to give an external/public IP address. How do I achieve this? Thanks! Sinan

Re: Info about procedure to shutdown hosted engine VM

Hi all, sorry for being late to such an interesting thread. I discussed almost this same issue (properly and programmatically shutting down a complete oVirt environment in a way that also guarantees a clean and easy power up later) privately with some friends some time ago. Please note that the issue has been already discussed on the mailing list before (we had started from those hints):http://lists.ovirt.org/pipermail/users/2017-August/083667.html I will translate here from Italian our description of the scenario, hoping to add something to the discussion (maybe simply as another use case): Setup: * We are talking about an hyperconverged oVirt+GlusterFS (HE-HC) setup (let's say 1 or 3 nodes, but more should work the same) * We are talking about abusing the "hyperconverged" term above (so CTDB/Samba/Gluster-NFS/Gluster- block are also running, directly on the nodes) ;-) Business case: * Let's say that we are in a small business setup and we do not have the luxury of diesel-powered generators guaranteeing no black-outs * Let's say that we have (intelligent) UPSs with limited battery, so that we must make sure that a clean global power down gets initiated as soon as the UPSs signal that a certain low threshold has been passed (threshold to be carefully defined in order to give enough time for a clean shutdown) * Let's say that those UPSs may be: * 1 UPS powering everything (smells single-point-of-failure, but could be) * 2 UPSs with all physical equipment having redundant (2) power cords * 3 or more UPSs somehow variously connected * Let's say the the UPSs may be network-monitored (SNMP on the ovirtmgmt network) or directly attached to the nodes (USB/serial) General strategy leading to shutdown decision: * We want to centralize UPS management and use something like NUT[1] running on the Engine vm * Network controlled UPSs will be directly controlled by NUT running on the Engine vm, while directly attached UPSs (USB/serial) will be controlled by NUT running on the nodes they are attached to, but only in a "proxy" mode (relaying actual control/logic to the NUT service running on the Engine vm) * A proper logic will be devised (knowing the capacity of each UPS, the load it sustains and what actually means to power down those connected equipment in view of quorum maintenance) in order to decide whether a partial power down or a complete global power down are needed, in case only a subset of UPSs should experience a low-battery event (obviously a complete low-battery on all UPSs means global power down) Detailed strategy of shutdown implementation: * A partial power down (only some nodes) means: * Those nodes will be put in local maintenance (vms get automatically migrated on other nodes or cleanly shut down if migration is impossible because of constraints or limited resources; shutdown of vms should respect proper order, using tags, dependency rules, HA status or other hints) but without stopping GlusterFS services (since there are further services depending on those, see below) * Services running on those nodes get cleanly stopped: * Proper stopping of oVirt HA Agent and Broker services on those nodes * Proper stopping of CTDB (brings down Samba too) and Gluster-block (NFS-Ganesha too, if used instead of Gluster-NFS) services on those nodes * Clean unmounting of all still-mounted GlusterFS volumes on those nodes * Clean OS poweroff of those nodes * A global power down of everything means: * All guest vms (except the Engine) get cleanly shut down (by means of oVirt guest agent), possibly in a proper dependency order (using tags, dependency rules, HA status or other hints) * All storage domains (except the Engine one) are put in maintenance * Global oVirt maintenance is activated (no more HA actions to guarantee that the Engine is up) * Clean OS poweroff of the Engine vm * Proper stopping of oVirt HA Agent and Broker services on all nodes * Proper stopping of CTDB (brings down Samba too) and Gluster- block (NFS-Ganesha too, if used instead of Gluster-NFS) services on all nodes * Clean unmounting of all still-mounted GlusterFS volumes on all nodes * Clean stop of all GlusterFS volumes (issued from a single, chosen node) * Clean OS poweroff of all nodes Sorry for the lenghty email :-) Many thanks. Best regards, Giuseppe PS: I will read through the official Ansible role for shutdown asap (I surely still need a lot of learning for writing proper Ansible playbooks... :-D )I just published our Ansible mockup [2]of the above detailed global strategy, but it's based on statically collected info and must be run from an external machine, to say nothing of my awful Ansible style and the complete lack of the NUT logic and configuration part On Wed, Sep 12, 2018, at 16:15, Simone Tiraboschi wrote: > > > On Wed, Sep 12, 2018 at 3:49 PM Gianluca Cecchi > <gianluca.cecchi(a)gmail.com> wrote:>> On Wed, Sep 12, 2018 at 10:03 AM Simone Tiraboschi >> <stirabos(a)redhat.com> wrote:>>> >>>> >>>> Does it mean that I have to run the ansible-playbook command from >>>> an external server and use as host in inventory the engine server, >>>> or does it mean that the ansible-playbook command is to be run from >>>> within the server where the ovirt-engine service is running and so >>>> keep intact the lines inside the smple yal file:>>>> " >>>> - name: oVirt shutdown environment >>>> hosts: localhost >>>> connection: local >>>> " >>>> >>> >>> Both options are valid. >> >> Good!

VNC Console on iOS device using Shotcuts
by hy3nk4＠gmail.com 28 Sep '18

28 Sep '18

Hi, I am currently experimenting with ability to connect VM console from iPad. I have developed a workflow in Shorcuts app (formerly Workflow). https://www.icloud.com/shortcuts/183ccea2fcca472c8e05b0eb766a8b39 You have to install VNC viewer that is able to open vnc:// url on your device. I am using VNC Viewer - Remote Desktop by RealVNC (https://itunes.apple.com/cz/app/vnc-viewer-remote-desktop/id352019548?mt=8) Workflow is far from perfect so if you have any ideas to improve this workflow I am surely listening.

Libvirt import to oVirt 3.5?
by Mark Steele 28 Sep '18

28 Sep '18

Hello, Is there a mechanism for importing VM's from a KEMU Libvirt host to oVirt 3.5? I see there is an import menu item for import on 4.1 but not on my installation of 3.5.

Enabling Gluster Service
by Maton, Brett 28 Sep '18

28 Sep '18

I just enabled the Gluster service in an existing oVirt 7.2.7-1 cluster via the Web-UI which put all hosts into non-operational status. Lots of events being created: Could not find gluster uuid of server host001.local on Cluster testlab. Could not find gluster uuid of server host002.local on Cluster testlab. Could not find gluster uuid of server host003.local on Cluster testlab. and a bunch of failed vm migrations Is it possible to add glusterfs after ovirt has been installed and configured?

Host restarting for unknown reasons
by turboaaa＠gmail.com 28 Sep '18

28 Sep '18

I have a dual host, self hosted engine, cluster/datacenter. I call these Node1 and Node2. They are running CentOS 7 and I have been running the updates regular by putting each host into maintenance mode and installing the update via the web gui. Node1 is restarting at odd times, causing VMs on that node to start up on Node2 (which is by design). However the restarts are becoming more frequent and I am having a hard time figuring out what is causing it. Below is a snippet from the /var/log/ovirt-hosted-engine-ha/agent.log on Node1. My current plan is to simply rebuild Node1 by re-installing CentOS 7, and using the cluster tools to import it.

Upgrading one of my oVirt Node hosts from 4.2.6 to 4.2.6.1 The host will not boot, it has the following message: node status: DEGRADED Please check the status manually using 'nodectl check' # nodectl check Status: FAILED Bootloader ... FAILED - It looks like there are no valid bootloader entries. Please ensure this is fixed before rebooting. Layer boot entries ... FAILED - No bootloader entries which point to imgbased layers **the rest of the message has a bunch of OK entries** How do I fix this?
