LDAP Bind failing because of SSLHandshakeException after Virtualization Manager was rebooted
by wbhegedus＠gmail.com 14 Nov '18

14 Nov '18

After moving and rebooting our Red Hat Virtualization Manager box to another node in our cluster, we are unable to make LDAP login work using StartTLS. No networking or configuration changes were made, but the logs indicate that the TLS negotiation is failing with our Active Directory domain controllers now. Specifically: "2018-11-13 10:33:12,500-05 WARN [org.ovirt.engineextensions.aaa.ldap.Framework] (ServerService Thread Pool -- 49) [] Exception: The connection reader was unable to successfully complete TLS negotiation: SSLHandshakeException(sun.security.validator.ValidatorException: No trusted certificate found), ldapSDKVersion=4.0.5, revision=b28fb50058dfe2864171df2448ad2ad2b4c2ad58" I have tried everything I can think of. I removed and reimported the certificate for the domain controller in the Java Keystore. I deleted the profile entirely and recreated it. I tried using the full certificate chain and I tried using single certificates from the chain, and all combinations together. For now, we have it working by specifying "pool.default.ssl.insecure = true" in the .properties file, but I'd prefer to have this working again using StartTLS. Is there something I am missing? I want to make sure that I'm not overlooking something before submitting any sort of bug report. Any help is appreciated. Thanks! PS - this is what the properties file looks like: [root@rhvm ~]# cat /etc/ovirt-engine/aaa/liberty.edu.properties include = <ad.properties> vars.domain = liberty.edu vars.user = cn=PREADER,ou=Service Accounts,ou=IS,OU=FSA,dc=University,dc=liberty,dc=edu vars.password = <redacted> pool.default.auth.simple.bindDN = ${global:vars.user} pool.default.auth.simple.password = ${global:vars.password} pool.default.serverset.type = srvrecord pool.default.serverset.srvrecord.domain = ${global:vars.domain} pool.default.ssl.startTLS = true pool.default.ssl.truststore.file = ${local:_basedir}/liberty.edu.jks

Replicated storage gets erased when added to new environment.
by Jacob Green 14 Nov '18

14 Nov '18

So I was testing with two Identical ovirt environments running the latest 4.2 environment. I have iscsi storage set up at Site A, and I have that same storage replicated to Side B, before I get into learning disaster recovery I wanted to see what importing the replicated storage would look like. However when I import it I get the follow, and the vms are wiped from the replicated storage I presented with iscsi. So is this possible with iscsi? Is there another way to go about doing this? My iscsi solution is freenas. -- Jacob Green Systems Admin American Alloy Steel 713-300-5690

Networking - interface and security questions
by davidk＠riavera.com 14 Nov '18

14 Nov '18

Hello, I'm trying to setup a new ovirt install and have run into some general issues that I hope someone can help with. I'm somewhat new to ovirt (but not virtualization). First off, I've been doing lots of reading and I can't seem to find what the generally accepted method is for firewalling access between networks and VMs is in ovirt? I see references to network filters, but no obvious ways to set ports or modify the configuration beyond a set list of general good-practice policies (no arp spoofing, etc). What do people use in a production environment? Trunk out to an external firewall and do the filtering there? Run iptables or some rules locally in each VM? Or just run pfSense or other firewall software as another VM and manage it there? And lastly, I'm trying to setup a new interface using the external ovn provider but am having problems. I can define the external provider network just fine (not connected to physical network), but can't seem to actually use it. When I create a new VM and assign the new network to an associated interface, the VM fails to start. The error I get is: "VM testvm is down with error. Exit message: Cannot get interface MTU on 'br-int': No such device." Am I missing something obvious here? I'm running oVirt 4.2.7 with the latest oVirt Node on a few hosts (also 4.2.7). All my configuration has been via the web interface so far. Sincerely,

RDP as default console for Windows VM
by Anantha Raghava 14 Nov '18

14 Nov '18

Hi, In the past, we could set RDP as default console for Windows VM. VMs used to reboot once we set RDP under console options & become default for all users. In the new versions I am unable to achieve the same result. Is there a way to set RDP as default Console for Windows VM? -- Thanks & Regards, Anantha Raghava eXzaTech Consulting And Services Pvt.

Ovirt VDI
by Hari Prasanth Loganathan 14 Nov '18

14 Nov '18

Hi Team, I created a VM which has one disk. For this VM, I created two Virtual Desktop (VDI_1 and VDI_2) using open-UDS and it created successfully. *Consider the following scenario* : 1) I took a console for VDI_1 and created a file in it using the console 2) I took the console for VDI_2 and checked whether the file created in VDI_1 is available in it but as per the VDI concept it is not available Could someone clarify the below use case, Now when I looked at the Disk associated with the VDI, It seems the Disk of the VM is same for the VDI_1 and VDI_2, so How does the file created in VDI_1 is not reflecting in VDI_2?

Can I Move a Fiber Channel Domain between different environments?
by Jacob Green 13 Nov '18

13 Nov '18

We have two Ovirt environments, our existing environment is Ovirt 4.1 And we want to migrate to our 4.2 environment, we chose this path because upgrading had a lot of issues for us, also we are migrating our cluster environment to a new IP scheme. So this made the most sense to us. The question we have now is can we simply move an existing Fiber Channel domain from our Ovirt 4.1 environment to our 4.2 environment. I see information here that suggests we can, https://ovirt.org/documentation/admin-guide/chap-Storage/ however there is information further down in the document that seems conflicting or I am confused, I am willing to accept that. *Near the top of the page I linked it says the following* "Note:The export storage domain is deprecated. Storage data domains can be unattached from a data center and imported to another data center in the same environment, or in a different environment. Virtual machines, floating virtual disk images, and templates can then be uploaded from the imported storage domain to the attached data center. SeeImporting Existing Storage Domains <https://ovirt.org/documentation/admin-guide/chap-Storage/sect-Importing_Exi…>for information on importing storage domains." **Ok cool so I should be able to import the storage domain into a new environment? According to that information it would seem so.* * *However further down it says the following,* "Reusing LUNs LUNs cannot be reused, as is, to create a storage domain or virtual disk. If you try to reuse the LUNs, the Administration Portal displays the following error message:" So I do not want to make a mistake, and remove my storage domain from my original ovirt environment just to find I cannot re add it to the new ovirt environment, and if I do that will I be able to import the VMs? Thank you for any guidance on this topic, It would be much appreciated. I guess the TLDR would be is the part pasted below of the linked documentation accurate for fiber channel? "Data Importing an existing data storage domain allows you to access all of the virtual machines and templates that the data storage domain contains. After you import the storage domain, you must manually import virtual machines, floating disk images, and templates into the destination data center. The process for importing the virtual machines and templates that a data storage domain contains is similar to that for an export storage domain. However, because data storage domains contain all the virtual machines and templates in a given data center, importing data storage domains is recommended for data recovery or large-scale migration of virtual machines between data centers or environments. Important: You can import existing data storage domains that were attached to data centers with a compatibility level of 3.5 or higher." Please forgive my confusion. -- Jacob Green Systems Admin American Alloy Steel 713-300-5690

Networking - How to pass all vlan (trunk) to a guest VM?
by Jonathan Greg 13 Nov '18

13 Nov '18

Hi, I didn't find the documentation about it... How I can pass all the vlan (trunk) to a guest VM (without SR-IOV)? My switch is configured to trunk all vlans. I do have configured a logical network with the "Enable VLAN tagging" box uncheck and assign it to a VM. My understanding with this setting is that tagged and untagged packet should be forwarded to the VM guest. Unfortunately it doesn't work at all, if I run a tcpdump on the VM nic attached to this logical network, I don't see anything... I would really like to run a virtual router or firewall on my setup without having to shutdown my VM and having attach a new vnic each time I want to add a new vlan. Any idea? Jonathan

Re: storage healing question
by Ravishankar N 12 Nov '18

12 Nov '18

Hi, Can you restart the self-heal daemon by doing a `gluster volume start bgl-vms-gfs force` and then launch the heal again? If you are seeing different entries and counts each time you run heal info, there is likely a network issue (disconnect) between the (gluster fuse?) mount and the bricks of the volume leading to pending heals. Also, there was a bug in arbiter volumes[1] that got fixed in glusterfs 3.12.15. It can cause VMs to pause when you reboot the arbiter node, so it is recommended to upgrade to this gluster version.

New disks cloned from template get wrong quota-id, when quota is disabled on DC
by Florian Schmid 12 Nov '18

12 Nov '18

Hi, we have recently upgraded our ovirt environment from 4.1.6 to 4.1.9 and then to 4.2.5. I don't know exactly when this issue was happened the first time, because on the affected DCs, we haven't created new VMs for some time ago. To our setup: We have several DCs configured and only the former default one has quota enabled. We have separate templates for each DC and they haven't been cloned or anything else from a template in default DC When I now create a VM on DC from a template (disks are cloned), where quota is not enabled, the new disks are getting quotas assigned, which are not available in that DC! The template disks all have the correct quota ID assigned!

As soon I enable quota on that DC, new disks created by VM creation via template, will get the correct quota ID. The problem with wrong IDs is, that you can't edit the disks anymore! I can repeat that error every time and I can give all the information you need to debug this. Pleas inform me, what data do you need... Best Regards Florian

storage healing question
by Dev Ops 12 Nov '18

12 Nov '18

The switches above our environment had some VPC issues and the port channels went offline. The ports that had issues belonged to 2 of the gfs nodes in our environment. We have 3 storage nodes total with the 3rd being the arbiter. I wound up rebooting the first 2 nodes and everything came back happy. After a few hours I noticed that the storage was up but complaining about being out of sync and needing healing. Within the hour I noticed a VM had paused itself due to storage issues. This is a small environment, for now, with only 30 VM's. I am new to Ovirt so this is uncharted territory for me. I am tailing some logs and things look sort of normal and google is sending me down a wormhole. If I run "gluster volume heal cps-vms-gfs info" this number seems to be changing pretty regularly. Logs are showing lots of entries like this: [2018-11-08 21:55:05.996675] I [MSGID: 114047] [client-handshake.c:1242:client_setvolume_cbk] 0-cps-vms-gfs-client-1: Server and Client lk-version numbers are not same, reopening the fds [2018-11-08 21:55:05.997693] I [MSGID: 108002] [afr-common.c:5312:afr_notify] 0-cps-vms-gfs-replicate-0: Client-quorum is met [2018-11-08 21:55:05.997717] I [MSGID: 114035] [client-handshake.c:202:client_set_lk_version_cbk] 0-cps-vms-gfs-client-1: Server lk version = 1 I guess I am curious what else should I be looking for? Is this just taking forever to heal? Is there something else I can run or I should do to verify things are actually getting better? I ran an actual heal command and it cleared everything for a few seconds and then the entries started to populate again when I did the info command.

Network/Storage design
by Josep Manel Andrés Moscardó 11 Nov '18

11 Nov '18

Hi, I am new to oVirt and trying to deploy a cluster to see whether we can move from VMWare to oVirt, but my first stopper is how to do a proper design for the infrastructure, how many networks do I need?, I have 2x10Gb SFP+ and 4x1Gb ethernet. For storage we have NFS coming from Netapp and ceph. Could someone point me in the right direction? Thanks.

libgfapi support are "false" by default in ovirt 4.2 ?
by Mike Lykov 09 Nov '18

09 Nov '18

Hi All I'm try to set up last ovirt version : ovirt-release42-pre.rpm repository Then, I install these (and many deps) rpms: ovirt-hosted-engine-setup-2.2.30-1.el7.noarch ovirt-engine-appliance-4.2-20181026.1.el7.noarch vdsm-4.20.43-1.el7.x86_64 vdsm-gluster-4.20.43-1.el7.x86_64 vdsm-network-4.20.43-1.el7.x86_64 All from that repository, and use webui installer for create glusterfs volumes (default suggested engine, data, vmstore) and then install hosted engine on that "engine" volume. In cluster I want to use libgfapi gluster storage access method, but when I import storages, created by installer at first step, VDSM mount it on hosts with FUSE. For Example ovirtstor1.miac:/engine on /rhev/data-center/mnt/glusterSD/ovirtstor1.miac:_engine type fuse.glusterfs (rw,relatime,user_id=0,group_id=0,default_permissions,allow_other,max_read=131072) ovirtnode1.miac:/data on /rhev/data-center/mnt/glusterSD/ovirtnode1.miac:_data type fuse.glusterfs (rw,relatime,user_id=0,group_id=0,default_permissions,allow_other,max_read=131072) I see in config, And it is disabled (false) [root@ovirtengine ~]# engine-config -a | grep -i libgf LibgfApiSupported: false version: 3.6 LibgfApiSupported: false version: 4.0 LibgfApiSupported: false version: 4.1 LibgfApiSupported: false version: 4.2 Why? Its is needed to enable it by hand? Like as in this presentation? https://www.slideshare.net/DenisChapligin/improving-hyperconverged-performa…

Storage domain mount error: Lustre file system (Posix compliant FS)
by okok102928＠fusiondata.co.kr 09 Nov '18

09 Nov '18

Hi. I am an ovirt user in Korea. I am working on VDI. It's a pleasure to meet you, the ovirt specialists. (I do not speak English well... Thank you for your understanding!) I am testing Lustre File System in Ovirt or RH(E)V environment. (The reason is simple: glusterfs and nfs have limit of performance, SAN Storage and excellent Software Defined Storage are quite expensive.) Testing for file system performance was successful. As expected, luster showed amazing performance. However, there was an error adding luster storage to the storage domain as Posix compliant FS. Domain Function : Data Storage Type : POSIX compliant FS Host to Use : [SPM_HOSTNAME] Name : [STORAGE_DOMAIN_NAME] Path : 10.10.10.15@tcp:/lustre/vmstore VFS Type : lustre Mount Options : The vdsm

Ovirt / RH(E)V An error occurs regardless of version. I have tested both in 3.6, 4.1, and 4.2 environments. I searched hard, but I did not have a similar case. I want to ask three questions. 1. Is there a way to fix the problem in Ovirt? (Secure bypass or some configurations) 2. (Extension of Question # 1) Where does block size 256512 come from? Why is it 256512? 3. Is this a problem you need to solve in the Lustre file system? (For example, a setting capable of direct IO in units of 512 bytes) I need help. Thank you for your reply.

Changing the system resources of the pool VM
by Hyung-Keun Kim 09 Nov '18

09 Nov '18

Hi. What I want to ask is simple. System resource changes in the Pool VM do not seem to be supported by ovirt. So let me ask you two questions. 1. Can you tell what the reason is? Are you related to the ovf file? 2. Is there any other way to use sub-templates? (Manual work is also fine) Is it possible to modify DB value only? If not, what else should I touch? Waiting for experts to answer. Thank you.
