The vdsm logs are not the correct ones.

Hello, I am having this same issue and have inserted the three new lines into /lib/python2.7/site-packages/ansible/modules/cloud/ovirt/ovirt_network.py yet it still occurs. I have rebooted the oVirt Node host. Do I need to insert the fix elsewhere or take other action to properly apply this fix? Thank you very much, Diamond Tours, Inc.

oVirt API - New vm on specified storage
by Tommaso - Shellrent 04 Feb '20

04 Feb '20

Hi to all. we are tring to create a new VM via API, but we are unable to select the desidered storage where to deploy it. We make a call like this: CALL: POST /ovirt-engine/api/vms?clone=true Data: {"cpu":{"topology":{"sockets":1,"cores":4,"threads":1}},"memory":4294967296,"memory_policy":{"guaranteed":4294967296,"max":4294967296},"disk_attachments":[{"disk":{"id":"925c999e-536f-4905-bc54-5cf64477a3a7","format":"cow","storage_domains":[{"id":"a772c71a-bd7b-4898-9497-120dcd853d96"}]}}],"name":"apitest.domain.com","fqdn":"apitest.domain.com","cluster":{"id":"890681f6-e0fe-11e9-81b5-0200007c8e05"},"template":{"id":"45da14a2-7f6f-43d9-9481-19a2034700fe"}} But the reply is: Reply HTTP 400 { "detail" : "For correct usage, see: https://XXXXXXX/ovirt-engine/apidoc#services/vms/methods/add", "reason" : "Request syntactically incorrect." } Have someone some suggestion or good example??

memory overcommit in oVirt
by yam yam 04 Feb '20

04 Feb '20

Hello, I thought memory overcommit feature in oVirt utilizes host's overcommit features by manipulating kernel variables like vm.overcommit_ratio, vm_overcommit_memory. but, I've just confirmed that those variables didn't change at all. I wonder if oVirt's overcommit really has nothing to do with that of host and if so, how does oVirt manage memory overcommit.

ESXi 6.7 as a nested VM on top of oVirt cluster.
by branimirp＠gmail.com 03 Feb '20

03 Feb '20

Hello list I am wondering if anyone has tried this before? I am trying to consolidate my lab to an oVirt cluster which consists of oVirt (4.3.8) and 2 KVM hypervisors (CentOS 7.7.). Among other things, one of my efforts is a small ESXi + vCenter lab. In addition, I have a standalone KVM hypervisor. I can run nested ESXi 6.7 on top of the standalone KVM hypervisor (with nested KVM enabled) without any problem. However, on top of oVirt-controlled KVMs I have some issues. The hypervisors have nested kvm support enabled via vdsm hooks. qemu emulates e1000 for a nested ESXi vm. ESXi installation process goes smooth but as soon as I enable management network and restart it, the nested ESXi cannot communicate with the outside world (DNS ping cannot pass). Also https connection to VMWare ESXi web gui and ping to the ESXi also fail. I noticed on my client machine, that ARP requests are incomplete for ESXI as well. Within oVirt, I see no packet drops in "Network interface" tab for the nested ESXi. In addition, I have a few, ordinary, non-nested VMs running on the same network as the nested vm and I can normally establish connection to those machines. Additionally, as a test, I created a nested KVM vm on top of the oVirt cluster, same network as the nested ESXi and it works as expected - can spin VMs, can connect to it. The network assigned to the nested ESXi has a "No network filter" vNic profile applied. I tried to google for a solution but found only this: https://github.com/mechinn/kvmhidden - not sure if this is the solution at all (also, I wonder if this is still up-to-date after 3+ years)? Could I please ask if anyone tried something similar and experienced this problem? Is there any additional configuration that I should apply to the oVirt cluster? Thank you very much in advance! Regards, Branimir
