[ovirt-users] From Self-hosted engine to standalone engine
Hello, we currently have a self-hosted engine on gluster with 3 hosts. We want to have the engine on a single machine on a standalone KVM. We did the following steps on our test platform. - Create a VM on a standalone KVM - Put the self hosted engine into global maintenance - Shut the self-hosted engine - Copy the self-hosted engine image disk (by browsing into the gluster engine volume) by using linux dd command to the standalone KVM - Reusing the self-hosted engine's MAC address on the new standalone VM - Starting the standalone VM which use the self-hosted image disk previously copied on the standalone KVM - Log in the engine and then undeploy the hosted-engine by re-installing all the host and go for UNDEPLOY on the self-hosted section - Stop ovirt-ha-agent and ovirt-ha-broker Everything seems to be ok for now. What do you think about our process ? (to go from self-hosted to standalone) Do you have any idea on what should be checked ? Thank you (We wanted to go out from self-hosted engine, because we don't really master this deployment) ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/5UZROLYIC273ARCXUIWHOIIVC3EPGS6E/
[ovirt-users] Re: Migrate datacenter with hosts and VM managed from engine no1 to engine no2
Hello Simone, at first, let me thank you for your answer. Ok for the storage domain. I have already done this before. The storage domain is a glusterfs domain. The glusterfs volume is composed of 3 hosts which are managed from the 1st engine. I wanted the detach the hosts, vm, storage domain from that engine and import everything on a new engine without loosing gluster volume info These are the steps I would like to do - stop all the VM - put into maintenance the storage domain - detach the storage domain from the datacenter - put all the host into maintenance - remove every host from the datacenter On the new engine: - create a new datacenter, cluster - add the host from the old datacenter (which does have glusterfs's conf) to the cluster - import the storage domain - import the VM from that storage domain Well I think I have to give a try on a test platform.

[ovirt-users] Migrate datacenter with hosts and VM managed from engine no1 to engine no2
Hello, we have the current setup. => 1 datacenter on site A with 1 cluster which is compose of 3 hosts and a self-hosted engine => 1 datacenter on site B (let's call this TATA) with 1 cluster compose of 3 hosts which is using glusterfs. This datacenter is managed by the self-hosted engine on site A We want to create on site B another datacenter with 1 cluster and another self-hosted engine then disengage datacenter TATA from self-hosted engine on site A. after that, we want to import all the ressource on the self-hosted engine on site B Is it possible to do this without loosing VM on glusterfs ? Off course VM will be shutdown during the operation. I mean, when a host is added on a new datacenter, ovirt will install package if necessary.

[ovirt-users] Failed to hot-plug disk
Hello,
I have a problem when i tried to hotplug a disk to a VM. Here is the situation.
We use a VM (let's call this backupVM) which is responsible of doing our VM
backup by :
- Making a snapshot of the VM we want to backup
- Attach the snapshot disk
- Make the copy using DD
- Unplug the snapshot disk and then delete snapshot.
For some reason that i don't know, for certain VM, the backupVM cannot hot plug
the snapshot disk.
I'm using ovirt 4.2.4
Here is what is see in engine.log

Hello, i used the vm_backup script as provide here : https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/vm_backup.py I understood the process to backup VM. I'm stuck at getting the logical_name of the disk when the snapshot disk is attached in a VM. I checked the flow like this: - The disk is attached on the VM - oVirt guest agent detect the new disk and the mapping seen on the LOG (i did put those log in DEBUG in /etc/ovirt-guest-agent.conf), i also reduce the report_disk_usage to 10 to speed up the process - VDSM on the host get the info from the ovirt guest agent seen by running the following command vdsm-client Host getVMFullList - On the engine the logical_name is empty seen with the following sql request select device,type,device_id, logical_name from vm_device where type='disk' and vm_id='XXX'; ovirt-engine-4.2.3.5-1.el7.centos.noarch vdsm-4.20.27.1-1.el7.centos.x86_64 ovirt-guest-agent-common-1.0.14-1.el7.noarch Do you have an idea ? Is the information request by the engine to VDSM ? VDSM does report to the engine ? What is the flow to get the logical_name populated in the engine DB, python SDK ? I can provide logs if needed.

[ovirt-users] Hardering oVirt Engine
Hello, we are subject to PCI-DSS. I have some questions. We currently have setup oVirt in our environnement. We created 2 Datacenter. - one with a cluster with hosted engine on gluster (Hyperconverged env) which represents the "LAN" part - one with a cluster with gluster storage wich is the DMZ In PCI-DSS we have to secure communication (use HTTPs as much as possible). I did saw that ovirt-ha-agent (on hosted-engine capable host) check the status of the engine by sending GET request on the hosted-engine on port 80 (the same check that hosted-engine --vm-status did in fact). Since ovirt 4.2.2, with the introduction of gluster eventing, a new flow (HTTP post resquest) is needed from gluster nodes to the engine. (In my case, it's a flow from the DMZ to the LAN part in HTTP (non secure) Here is my question. Is it possible to "hardering" this part of the engine ? Another question out of PCI scope. Events like warning and error in the dashboard are clean each days. I tried to find which process did that (look into /etc/cron.daily, root crontab, etc) on the engine without succes. Is there any maintenance task that is run periodicaly ? Could we have the list of all the engine's task ? (regulary check the status of host, vm, storage) also the frequency ? I would appreciate the help. (Great great product ovirt !) Thank you for your jobs ! We did manage KVM hypervisor as standalone machine without all the power that libvirt provides.
