Windows VMs won't boot in debug mode
by Andrew X 17 Jul '18

17 Jul '18

Hi Everyone, I've been having problems getting Windows 10 VMs to boot in debug mode after turning on debugging over network (steps below). Also, device manager in Windows is not showing the processors' node which might be related (same reason why Windows is refusing to boot in debug mode?). I don't have any of these problems when I use generic KVM or Proxmox KVM. To turn on debugging in Windows, I do the follwoing from an admin terminal window: bcdedit /debug on bcdedit /dbgsettings net hostip:a.b.c.d port:p key:1.2.3.4 Any help will be appreciated, Thanks, Andrew

17 Jul '18

Dear users, I would love to get some feedback if someone has tried to install and use the oVirt metrics store, released in 4.2, for collecting metrics and logs, based on Elasticsearch, Kibana, Collectd and Fluentd on top of OpenShift. https://www.ovirt.org/develop/release-management/features/metrics/metrics-s… How did the installation go? Are you actively using it? And any other feedback would be much appreciated.

Disk Statistics API in oVirt
by Hari Prasanth Loganathan 17 Jul '18

17 Jul '18

Hi Team, We are using the following API to collect the disk statistics, https://X.X.X.2/ovirt-engine/api/ *disks/2331bad7-71ec-4fad-95bb-2b3449f3dbda/statistics* <https://X.X.X.2/ovirt-engine/api/disks/2331bad7-71ec-4fad-95bb-2b3449f3dbda…> I found one issue in the disk statistics. In case If the Virtual Machine has this disk (*2331bad7-71ec-4fad-95bb-2b3449f3dbda*) attached to it and I perform some read / write operation in the VM and it increases the corresponding disk level Read data rate / Write data rate / disk.read.latency / disk.write.latency. *Example*, I received the following values for this disk, But the problem is even when I bring down the VM still the last known value is received continuously. *Is it a known issue Or any workaround is available? * *Expected : All values should go to Zero* *Actual : All values retains the last known values when the VM was in UP state. * { "statistic": [ { "kind": "gauge", "type": "decimal", "unit": "bytes_per_second", "values": { "value": [ { "datum": 2184 } ] }, "disk": { "href": "/ovirt-engine/api/disks/2331bad7-71ec-4fad-95bb-2b3449f3dbda", "id": "2331bad7-71ec-4fad-95bb-2b3449f3dbda" }, "name": "data.current.read", "description": "Read data rate", "href": "/ovirt-engine/api/disks/2331bad7-71ec-4fad-95bb-2b3449f3dbda/statistics/33b9212b-f9cb-3fd0-b364-248fb61e1272", "id": "33b9212b-f9cb-3fd0-b364-248fb61e1272" }, { "kind": "gauge", "type": "decimal", "unit": "bytes_per_second", "values": { "value": [ { "datum": 41202005 } ] }, "disk": { "href": "/ovirt-engine/api/disks/2331bad7-71ec-4fad-95bb-2b3449f3dbda", "id": "2331bad7-71ec-4fad-95bb-2b3449f3dbda" }, "name": "data.current.write", "description": "Write data rate", "href": "/ovirt-engine/api/disks/2331bad7-71ec-4fad-95bb-2b3449f3dbda/statistics/2f23addd-4ebd-3d82-a449-c28778bc33eb", "id": "2f23addd-4ebd-3d82-a449-c28778bc33eb" }, { "kind": "gauge", "type": "decimal", "unit": "seconds", "values": { "value": [ { "datum": 0.12 } ] }, "disk": { "href": "/ovirt-engine/api/disks/2331bad7-71ec-4fad-95bb-2b3449f3dbda", "id": "2331bad7-71ec-4fad-95bb-2b3449f3dbda" }, "name": "disk.read.latency", "description": "Read latency", "href": "/ovirt-engine/api/disks/2331bad7-71ec-4fad-95bb-2b3449f3dbda/statistics/3a7b3f72-d035-3bb9-b196-e86a4eb34993", "id": "3a7b3f72-d035-3bb9-b196-e86a4eb34993" }, { "kind": "gauge", "type": "decimal", "unit": "seconds", "values": { "value": [ { "datum": 1.4 } ] }, "disk": { "href": "/ovirt-engine/api/disks/2331bad7-71ec-4fad-95bb-2b3449f3dbda", "id": "2331bad7-71ec-4fad-95bb-2b3449f3dbda" }, "name": "disk.write.latency", "description": "Write latency", "href": "/ovirt-engine/api/disks/2331bad7-71ec-4fad-95bb-2b3449f3dbda/statistics/b1e75c7b-cea4-37d2-8459-f7d68efc69a3", "id": "b1e75c7b-cea4-37d2-8459-f7d68efc69a3" }, { "kind": "gauge", "type": "decimal", "unit": "seconds", "values": { "value": [ { "datum": 0 } ] }, "disk": { "href": "/ovirt-engine/api/disks/2331bad7-71ec-4fad-95bb-2b3449f3dbda", "id": "2331bad7-71ec-4fad-95bb-2b3449f3dbda" }, "name": "disk.flush.latency", "description": "Flush latency", "href": "/ovirt-engine/api/disks/2331bad7-71ec-4fad-95bb-2b3449f3dbda/statistics/9c17ad7b-9ef1-3e8d-ad0a-ff8bee3925f0", "id": "9c17ad7b-9ef1-3e8d-ad0a-ff8bee3925f0" } ] } Thanks, Hari -- DISCLAIMER - *MSysTechnologies LLC* This email message, contents and its attachments may contain confidential, proprietary or legally privileged information and is intended solely for the use of the individual or entity to whom it is actually intended.

Hello, This is more out of curiosity, I was wondering during a migration or import/export does all the storage traffic goes through the SPM server? Thanks John

Jump from a disk to its storage domain from VM disk
by Gianluca Cecchi 16 Jul '18

16 Jul '18

Hello, currently on 4.2.3 I can - Select Storage --> Disks - Select disk link in the line (in the "Alias" column) - In the new disk page select "Storage" tab and I can see the related Domain Name and its information (eg free space if I want to extend the disk) --> it would be nice to have a "link" on domain name so that you can directly jump to Storage --> Domains --> Domain Name It would be nice to have similar behavior also directly starting from Compute --> Virtual Machines Select VM --> Disks Select disk Here I can select "edit" and then in the edit window I can see information about storage domain between the other fields. It would be nice to have a pointer to directly go to the storage domain containing that disk. Gianluca

oVirt - Scaling out from one to many
by Leo David 16 Jul '18

16 Jul '18

Hello everyone, I have two things that i really need to understand regarding storage scaling using gluster. Basically, I am trying to figure out a way to go from 1 single instance to multiple nodes cluster. 1. Single node SelfHosted Engine HyperConverged setup - scale instance up to 3 nodes: - the gluster volumes are created as distributed type. - is there a procedure to migate this single-host scenario to multiple nodes, considering that the 3 nodes setup is using replica 3 gluster volumes ? 2. 3 Nodes SelfHosted Engine - add more storage nodes - how should I increase the size of the already present replica 3 volumes ? - should the volumes be as distribute-replicated in an environment larger than 3 nodes ? 3. Is there a limit as a maximum number of compute nodes per cluster ? Thank you very much ! Leo -- Best regards, Leo David

ovirt 3.8 to ovirt 4.2 Migration.
by techieim 15 Jul '18

15 Jul '18

Hello Team Ovirt, We are running Ovirt3.8 version in our prod, we want to upgrade to 3.8 to 4.2. At present we have 2 (hyp A & hyp B)physical host ovirt 3.8 is running with self hosted engine with data domain and iso one cluster and data center. What we were thing do this migration in following fashion. Plan A. 1. Attach export domain present infra. 2. Take backup all of running vm as export. 3. Detach export domain 4. Detach hyp B from cluster and data center 5. Install fresh ovirt 4.2 iso on hyp B 6. Install self hosted engine 7. Attach Data Domain 8. Attach Export Domain which was use in ovirt 3.8 9. Import all vm's from there to new ovirt 4.2 10. Once all the vm's got up and running poweroff hyp A 11. Install fresh ovirt 4.2 iso on hyp A and attach cluster. Plan B. 1. Attach export domain present infra. 2. Take backup all of running vm as export. 3. Detach export domain 4. Detach hyp B from cluster and data center 5. Install fresh ovirt 4.2 iso on hyp B 6. Install self hosted engine 7. Attach Data Domain 8. Export from ovirt 3.8 to ovirt 4.2 9. Once all the vm's got up and running poweroff hyp A 10. Install fresh ovirt 4.2 iso on hyp A and attach cluster. Thank a ton in advance we may be wrong with above step help us to win this migration. Regards Techieim
