Engine expands CPU and memory
by xilazz＠126.com 28 May '20

28 May '20

Hi, everyone. When I use the ovirt cluster, there are multiple virtual machines in the cluster.Engine controller shows excessive CPU load during administration, I would like to ask if there is a way to extend engine controller CPU and memory online, I would be very grateful.thank you

oVirt not using local GlusterFS bricks
by Randall Wood 28 May '20

28 May '20

I have a three node oVirt 4.3.7 cluster that is using GlusterFS as the underlying storage (each oVirt node is a GlusterFS node). The nodes are named ovirt1, ovirt2, and ovirt3. This has been working wonderfully until last week when ovirt2 crashed (it is *old* hardware; this was not entirely unexpected). Now I have this situation: all three oVirt nodes are acting as if the GlusterFS volumes only exist on ovirt2. The bricks on all three nodes appear to be in sync. I *think* this began happening after I restarted ovirt2 (once hard, and once soft) and then restarted glusterd (and only glusterd) on ovirt1 and ovirt3 after `gluster-eventsapi status` on those two nodes showed inconsistent results (this had been used with success before). How can I make the oVirt nodes read and write from their local bricks?

oVirt 4.4 pending VM changes on HostedEngine VM
by Radoslav Milanov 28 May '20

28 May '20

Hello I'm not sure how but I've got pending changes on the HostedEngine VM on a 3 node 4.4 cluster and those changes are never applied. Is there a way to cancel pending VM changes in general ? Thanks.

Adding extra parameters to qemu-kvm
by Sakari Poussa 28 May '20

28 May '20

Hi, Before I dive in too deeply to vdsm-hook-qemucmdline I'd like to know if it is the correct solution to my needs. I want to add the following (type of) parameters to VM startup -object memory-backend-file,id=mem1,share=on,mem-path=/dev/dax0.0,size=$PMEM_SIZE,align=2M \-device nvdimm,id=nvdimm1,memdev=mem1,label-size=128k \ Is the vdsm-hook-qemucmdline the correct tool? Can I use (add the params) it also from the ansible playbook (via ovirt roles) somehow? Thanks, Sakari

Current Architecture of oVirt and Quality Assurance measures
by Juergen Novak 28 May '20

28 May '20

I am currently evaluating oVirt for the usage in big companies as base system for edge computing applications. I already tried to find a current architecture overview regarding the oVirt modules -- particularly ovirt-node-ng and imgbased. But I did not manage to find any. There is some architecture documentation, but marked as outdated and many links go to 404. So I would ask, if somebody could provide any current architecture overview (no user documentation), particularly of the node module(s). An other question I have, is which quality measures are used in development? * Tools used (for Unit-Tests, Component-Tests, Integration-Tests) * Are there any statistics about test coverage? Any assistance would be appreciated. Best Regards /juergen

oVirt 4.4 gluster single host vm paused due to unknown storage error
by Gianluca Cecchi 28 May '20

28 May '20

Hello, in environment in subject, I downloaded from glance repository the CentOS 8 image CentOS 8 Generic Cloud Image v20200113.3 for x86_64 (5e35c84) and imported as a template. I created a vm based on it (I got the message: "In order to create a VM from a template with a different chipset, device configuration will be changed. This may affect functionality of the guest software. Are you sure you want to proceed?") When running "dnf update", during I/O of packages updates the VM went into pause. VM c8desktop started on Host novirt2.example.net 5/28/201:29:04 PM VM c8desktop has been paused. 5/28/201:41:52 PM VM c8desktop has been paused due to unknown storage error. 5/28/201:41:52 PM VM c8desktop has recovered from paused back to up. 5/28/201:43:50 PM In messages of (nested) host I see: May 28 13:28:06 novirt2 systemd-machined[1497]: New machine qemu-7-c8desktop.

I see in 4.4 Gluster is glusterfs-7.5-1.el8.x86_64 Can this be a problem that only appears in single host as there are indeed no data travellling to the network to sync nodes and sharding feature for some reason is not able to keep pace, when local disk is very fast? In 4.3.9 single host with gluster 6.8-1 my only way to solve was to disable sharding.. and I got final stability see here https://lists.ovirt.org/archives/list/users@ovirt.org/thread/OIN4R63I6ITOQS… Still waiting for Gluster devs comments on logs provided at that time As I already wrote, in my opinion the single host wizard should set sharding off in automatic, because in that environment can make thin provisioned disks unusable. In case of future additions of nodes, the setup can make a check and say the user that he/she should re-enable sharding.... Just my 0.2 eurocent Gianluca

This update is the first in a series of stabilization updates to the 4.4 series. Important notes before you try it Please note this is a pre-release build. The oVirt Project makes no guarantees as to its suitability or usefulness. This pre-release must not be used in production. Some of the features included in oVirt 4.4.1 Release Candidate require content that will be available in CentOS Linux 8.2 but can’t be tested on RHEL 8.2 yet due to some incompatibility in openvswitch package shipped in CentOS Virt SIG which requires to rebuild openvswitch on top of CentOS 8.2. Installation instructions For the engine: either use appliance or: - Install CentOS Linux 8 minimal from http://centos.mirror.garr.it/centos/8.1.1911/isos/x86_64/CentOS-8.1.1911-x8… - dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44-pre.rpm - dnf update (reboot if needed) - dnf module enable -y javapackages-tools pki-deps postgresql:12 - dnf install ovirt-engine - engine-setup For the nodes: Either use oVirt Node ISO or: - Install CentOS Linux 8 from http://centos.mirror.garr.it/centos/8.1.1911/isos/x86_64/CentOS-8.1.1911-x8… ; select minimal installation - dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44-pre.rpm - dnf update (reboot if needed) - Attach the host to engine and let it be deployed. This release is available now on x86_64 architecture for: * Red Hat Enterprise Linux 8.1 or newer * CentOS Linux (or similar) 8.1 or newer This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for: * Red Hat Enterprise Linux 8.1 or newer * CentOS Linux (or similar) 8.1 or newer * oVirt Node 4.4 based on CentOS Linux 8.1 (available for x86_64 only) See the release notes [1] for installation instructions and a list of new features and bugs fixed.

ovirt 4.4.0 - Live merge failure with libvirt error "virDomainBlockCommit() failed"
by Marco Fais 27 May '20

27 May '20

Hi, I have upgraded one of my nodes to oVirt-node 4.4.0 and I am testing the basic functionality in preparation for the full cluster migration. Unfortunately snapshot deletions are not working at the moment; I have a live merge failure most of the times due to a libvirt error -- virDomainBlockCommit() failed I have opened a bug on this as well (https://bugzilla.redhat.com/show_bug.cgi?id=1840414) See the most relevant portion of the vdsm.log here: 2020-05-26 22:43:39,067+0100 ERROR (jsonrpc/1) [virt.vm] (vmId='baaf6be8-dcf4-4f26-b0f1-435287eeed95') Live merge failed (job: 7b96452b-0e60-46c6-9236-6b8a906b0ed8) (vm:5381) Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/vdsm/virt/vm.py", line 5379, in merge bandwidth, flags) File "/usr/lib/python3.6/site-packages/vdsm/virt/virdomain.py", line 101, in f ret = attr(*args, **kwargs) File "/usr/lib/python3.6/site-packages/vdsm/common/libvirtconnection.py", line 131, in wrapper ret = f(*args, **kwargs) File "/usr/lib/python3.6/site-packages/vdsm/common/function.py", line 94, in wrapper return func(inst, *args, **kwargs) File "/usr/lib64/python3.6/site-packages/libvirt.py", line 728, in blockCommit if ret == -1: raise libvirtError ('virDomainBlockCommit() failed', dom=self) libvirt.libvirtError: internal error: qemu block name 'json:{"backing": {"driver": "raw", "file": {"driver": "file", "filename": "/rhev/data-center/mnt/glusterSD/192.168.30.2:_Temp__Storage/246845e5-5546-4f04-948e-66a9532b403f/images/64955343-da61-4b76-9158-8df8363dc5a3/b0558698-bc82-4941-ac52-9fa2385a9f00"}}, "driver": "qcow2", "file": {"driver": "file", "filename": "/rhev/data-center/mnt/glusterSD/192.168.30.2:_Temp__Storage/246845e5-5546-4f04-948e-66a9532b403f/images/64955343-da61-4b76-9158-8df8363dc5a3/be844ebe-10b6-4ac7-89c1-9f8526a52762"}}' doesn't match expected '/rhev/data-center/mnt/glusterSD/192.168.30.2:_Temp__Storage/246845e5-5546-4f04-948e-66a9532b403f/images/64955343-da61-4b76-9158-8df8363dc5a3/be844ebe-10b6-4ac7-89c1-9f8526a52762' 2020-05-26 22:43:39,075+0100 INFO (jsonrpc/1) [api.virt] FINISH merge return={'status': {'code': 52, 'message': 'Merge failed'}} from=::ffff:10.144.138.240,60914, flow_id=dbf9c831-e0cb-4891-a38c-d61136daf029, vmId=baaf6be8-dcf4-4f26-b0f1-435287eeed95 (api:54) 2020-05-26 22:43:39,075+0100 INFO (jsonrpc/1) [jsonrpc.JsonRpcServer] RPC call VM.merge failed (error 52) in 0.18 seconds (__init__:312) This issue was reported also on https://bugzilla.redhat.com/show_bug.cgi?id=1785939; according to the comments the resolution seems to be in libvirt 6.x. However I am not quite sure if / how I can get libvirt 6 in my setup... is there a test image (ideally ovirt-node) I can use? Any suggestions? Unrelated: I had also a problem during the hosted-engine deployment due to the fact the machine is not connected directly to internet and could not complete the dnf update steps (even with the proxy configured it was still failing at a later stage during the engine setup, same problem..). I might open another thread on it... Thanks, Marco
