Problems with ovirt-web-ui-1.6.0-1.el7.noarch
by Matthias Leopold 24 Dec '19

24 Dec '19

Hi, after upgrading oVirt from 4.3.5 to 4.3.7 some things in the VM Portal stopped working for users with "User" role: * running guest agent is not recognized ("It looks like no guest agent is configured on the VM.") * CD/ISO list is "[Empty]" for this I found "- limit CD/ISO list by data center" in rpm changelog, but this doesn't help me in any way Assigning other roles (UserVmRunTimeManager, PowerUserRole) doesn't change anything. /var/log/ovirt-engine/ui.log is quiet. Downgrading to ovirt-web-ui-1.5.3-1.el7.noarch resolves both issues. Am I the only one who is experiencing this? thx for advice Matthias

Re: Strategy to Mange Ovirt VMs Created from Templates

Sealing the VM is not something specific to oVirt, and is also valid for KVM. Actually sealing the VM is to run virt-sysprep against the VM/disk. You can check http://libguestfs.org/virt-sysprep.1.html and especially the --list-operations which can help you understand what ia being cleaned up. So you can: 1. Update the VM 2. Install and enable cloudinit service 3. Maybe try to create your ansible user and allow ssh keys (Using ansible over root is not good and is a bad practice) 4. Power off and seal the machine as a template (details at https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualiza… ) 5. Create VM from the template and power it up manually. 6. Verify that the new VM matches your needs and remove. About cloud init - you should know that is used extensively in OpenStack and VmWare has it's own solution similar to CloudInit. Some examples can be found at: https://cloudinit.readthedocs.io/en/latest/topics/examples.html So you can change passwords, configure network, create your ansible user with necessary permissions and way more.

Strategy to Mange Ovirt VMs Created from Templates
by jeremy_tourville＠hotmail.com 23 Dec '19

23 Dec '19

I want to be able to manage VMs using Ansible. As part of the template creation process it says to seal the VM. Can someone tell me what sealing does to a Linux VM? I understand it removes some of things that make the VM unique but no real specifics. So, if I want to manage a VM created from a template would this general process work?- Seal the VM Install CloudInit and keys, accounts, etc Shut off VM and create template from it. Create new VM using Ansbile & CloudInit CloudInit would have just enough info so that you could manage the VM with Ansible. Would that work? I am just starting to explore what CloudInit can do and what it is. I am brand new to it. I didn't find enough info on template sealing to help me devise a full cycle management strategy. Perhaps there are other/easier methods? Thanks for your advice and input.

Dear All: My ovirt engine managed two vdsms with nfs storage on another nfs server, it worked fine about three months. One of host (host_1.3; ip:172.18.1.3) was created about 16 vms, but the host_1.3 was shutdown unexpectly about 2019-12-23 16:11, when re-started host and vms; half of the vms was lost some configure or changed , such as lost theirs ip etc.(the vm name is 'zzh_Chain49_ACG_M' in the vdsm.log) the vm zzh_Chain49_ACG_M was create by rest API through vm's templated . the template is 20.1.1.161; the vm zzh_Chain49_ACG_M was created by ovirt rest api and changed the ip to 20.1.1.219 by ovirt rest api. But the ip was changed to templated ip when the accident happened. the vm's os is centos. Hope get help from you soon, Thank you. Mark Sincerely.

iSCSI connections and storage put into maintenance
by Gianluca Cecchi 22 Dec '19

22 Dec '19

Hello, I have a cluster composed by two hosts connected to some iSCSI storage domains. I have put one host into maintenance and I see that all the iSCSI sessions are closed. So far so good. Then I put one storage domain into maintenance and I would expect to see on the active host the (2) iSCSI sessions versus this storage domain to get closed. Instead I continue to see them up and "multipath -l" command gives me the 2 paths for the LUN part of the storage domain connection. Is this expected and only when I execute detach of the SD I will get the closure of the iSCSI connections? Because the detach phase will unregister the VMs and I would like not to do it, but at the same time I will have a planned maintenance for this storage domain and I would like to clean the connections on host side, to let multipath happy when they will go down for some hours... Thanks in advance for any insight. Gianluca
