Info about openstack staging-ovirt driver connection not released
by Gianluca Cecchi 28 Apr '20

28 Apr '20

Hello, I'm setting up an Openstack Queens lab ( to best match OSP 13) using oVirt VMs as nodes. At this time only undercloud configured and 8 Openstack nodes (VMs) set as available for provisioning. I'm using staging-ovirt driver on director node in similar way as the vbmc one. I see from oVirt active user sessions page that every minute I have one connection for node (in my case 8) of the designated user (in my case ostackpm). But it seems they are never released. How can I check the problem? Director is CentOS 7 server and the staging-ovirt driver is provided by the package: [root@director ~]# rpm -q python-ovirt-engine-sdk4 python-ovirt-engine-sdk4-4.3.2-2.el7.x86_64 [root@director ~]# I didn't configure the oVirt repo but only installed the latest stable available for 4.3.9: wget https://resources.ovirt.org/pub/ovirt-4.3/rpm/el7/x86_64/python-ovirt-engin… sudo yum localinstall python-ovirt-engine-sdk4-4.3.2-2.el7.x86_64.rpm Anyone with experience on this? In the mean time any way to use a command using api to kill the stale (I think) sessions? Thanks, Gianluca

Virtual machine replica - DR
by ccesario＠blueit.com.br 28 Apr '20

28 Apr '20

Hello, Does someone know any tool/method to replicate the VMS from a "Production" Cluster to "Secondary" Cluster, to provide a DR solution without Storage replication dependency or Gluster Storage. Like Veeam, Zerto toosl do with other hypervisors. Is there anyway, tool, product to do it!? Regards Carlos

Custom ignition in cloud-init?
by Wesley Stewart 26 Apr '20

26 Apr '20

Before anyone tells me this is now included in 4.4.0, I saw this, but I don't think I'm willing to update my centos7 host to centos8 yet. (But perhaps that will be the answer). Currently on 4.3.9/Centos 7 I am trying to run fedora core is to test it out, and the ISO installer hangs on: "failed to isolate default target freezing" So I tried the QCOW2 image, but I'm looking at ways of running the ignition file. I see in the "run once" section i can deploy a custom unit script, and I was wondering is this filetype agnostic? If I generate a JSON ignition script and put it in there will it get passed through correctly ? Or will I need to update to 4.4.0? I also found: https://gerrit.ovirt.org/#/c/100008/ This was abondoned for a "better solution" last September. Was this referring to the changes in 4.4.0? Lastly has anyone who was running 4.3.9 upgrade their centos host to centos8 and then upgrade ovirt without any issues? I usually try and wait at least a couple of minor version changes before switching to a new major version. Thanks guys!

Ovirt vs lvm?
by csabany＠freemail.hu 26 Apr '20

26 Apr '20

Hi, Our production ovirt system looks like: standalone management server, vesion 4.3.9, 6 clusters, 28 nodes (v4.2, v4.3) , one storage domain, (FC SAN Storages), centos7 vm-s , and some windows vms. I have a returning problem. Sometime when i power off a vm and power on again , i get an error message our linux vm (when we use lvm of course): dracut: Read-only locking type set. Write locks are prohibited., dracut: Can't get lock for vg. I can repair only 70% of damaged vm. I tried to localize the problem, but a can`t. The error occured randomly every cluster, every storage on last 2 years. Has anyone ever encountered such a problem?

How to force removal of old host from Engine
by Shareef Jalloq 24 Apr '20

24 Apr '20

Hi, I seem to have got a stale host in my engine that I can't remove. I recently reinstalled oVirt Node on this host and while trying to refresh the host in the engine, have got it in some state where I can't do anything. The host is listed as Status=Unassigned. Under the Management pull down I only have Restart and Stop options, both of which error if selected. The Remove button is not available. How do I force a removal of this host from the view so I can reload it? Shareef.

Move Hosted Engine VM to a different storage domain
by Anton Louw 24 Apr '20

24 Apr '20

Hi All, I know this question has been asked before, by myself included. I was hoping that someone has run through the exercise of moving the hosted engine VM to a different storage domain. I have tried many routes, but the backup and restore does not work for me. Is there anybody that can perhaps give me some guidelines or a process I can follow? The reason I need to move the HE VM is because we are decommissioning the current storage array where the HE VM is located. Thank you very much Anton Louw Cloud Engineer: Storage and Virtualization ______________________________________ D: 087 805 1572 | M: N/A A: Rutherford Estate, 1 Scott Street, Waverley, Johannesburg anton.louw(a)voxtelecom.co.za www.vox.co.za

This ovirt-administrator group is only for accessing(authentication & sso) ovirt engine admin panel and, as far as I understand it, it does restrict access to particular engine's admin functions.

Batch delete Snapshots
by Christian Reiss 22 Apr '20

22 Apr '20

Hey folks, quick question: Can this be made batch-able? # gluster snapshot delete all System contains 1 snapshot(s). Do you still want to continue and delete them? (y/n) So for a script I could do a snapshot, copy the contents and auto-remove all snapshots after. I could go with snapshot list and act on those, but this seems like it should be in the code? -Chris. -- with kind regards, mit freundlichen Gruessen, Christian Reiss

With so much experience in IPTABLES - it's understandable, but keep in mind that in CentOS/RHEL 8 iptables command is just a translator to nftables - with limited capability and I don't think that it was a coincidence . With firewalld you can still achive 90-95% of what you could do in IPTABLES while the rules are quite clear even for a new admin. What I really like is that you can predefine the ports and protos for a specific service and easily deploy it via salt or ansible. Best Regards, Strahil Nikolov

Safely disable firewalld [Ovirt 4.3]
by francesco＠shellrent.com 22 Apr '20

22 Apr '20

Hi all, I was wondering if it's "safe" disabling entirely the firewalld service and manage the firewall only via iptables, on the host and on the hosted engine (a self-hosted engine). It would make a lot easier the managing the firewall rules for me because of many automatisms I created based on iptables. Did anyone manage to do this? Any contraindication for doing this or precaution that I have to take care of? Thanks for your time and help, Francesco

Ok so this is definitely looking better.

However, now I recall I made some changes compared to blog post example: 1) /etc/ovirt-engine/extensions.d/openid-http-mapping.properties I added escaping in regexp for '\' ... config.mapAuthRecord.regex.pattern = ^(?<user>.*?)((\\\\(?<at>@)(?<suffix>.*?)@.*)|(?<realm>@.*))$<file://(%3f%3cat%3e@)(%3f%3csuffix%3e.*%3f)@.*)(%3f%3crealm%3e@.*))$)$> ... 2) /etc/httpd/ovirt-openidc.conf Escaping for '"' in error document snippet ... <LocationMatch ^/ovirt-engine/sso/(interactive-login- negotiate|oauth/token-http-auth)|^/ovirt-engine/callback> <If "req('Authorization') !~ /^(Bearer|Basic)/i"> Require valid-user AuthType openid-connect ErrorDocument 401 "<html><meta http-equiv=\"refresh\" content=\"0; url=/ovirt-engine/sso/login-unauthorized\"/><body><a href=\"/ovirt-engine/sso/login-unauthorized\">Here</a></body></html>" </If> </LocationMatch> ... These two issues were most probably caused by the blog site rendering. You might want to check engine.log (or server.log not really sure which one was that) for aaa extension initialization logs. They should appear at the beginning just after restarting engine. Unfortunately, at the moment I do not have running keycloak setup (I used to have a local VM) but I will try to find some time to set it up again once I'm done with another work item that actually consumes almost entire disk space for my 2 machines) Please let me know if anything changes after applying these config changes. It this works for you then I will request the blog post to be updated. Do you mind if I keep(re-post) this discussion back to users@ovirt in case other might have similar issues with keycloak integration? A.

Hello oVirt Community / infrastructure team, we would like to get guidance on how to mirror the oVirt content publicly. We replicate content using our own networks so we'd only be pulling the content from the oVirt content server from one location in Chicago. Please advise. Thank you, Adrian

Hopefully, I would be able to help you with it. There is excellent blog post[1] available. You might also check keycloak+ldap post [2], however, when I was working on the integration I was not aware of if and did not test it. The error you mentioned does not really indicate what exactly is wrong but it might suggest that there is some sort of misconfiguration with apache (you need to install and configure mod_auth_openidc as described at [1]). At least that happened in my case. In case you have already gone through it you could probably check apache logs. Under [1] there is a python script that can be used to check api calls, please update username/password and test it against your environment. Would it be possible post relevant piece of apache logs together with engine.log ?

oVirt and KeyCloak intergration
by Anton Louw 21 Apr '20

21 Apr '20

Hi Everybody, Has anybody gone the route of using KeyCloak to login to oVirt? KeyCloak has been configured and the neccesary configs have also been done on the engine. It redirects perfectly from the oVirt Web Login page to KeyCloak, but after logging into KeyCloak, I get redirected back to the oVirt Web Login. When trying to login again, I get the below error: [cid:ea1b2738-7e36-4cdb-8650-191d6992853c] server_error: Missing parameter: 'params' I have checked all the logs, but nothing is telling me what exactly the issue is. If anybody has any idea, please let me know. Thanks Anton Louw Cloud Engineer: Storage and Virtualization ______________________________________ D: 087 805 1572 | M: N/A A: Rutherford Estate, 1 Scott Street, Waverley, Johannesburg anton.louw(a)voxtelecom.co.za www.vox.co.za

Migrate engine to another storage domain without losing engine settings?
by Simon Nylund 21 Apr '20

21 Apr '20

Have been trying to figure out a simple way of migrating our hosted-engine to another storage domain, while keeping the data on the same domain. Is there any safe way of doing this? Fortunately I've only tested this in a dev environment, where I ended up with not being to able to restore the backup I did. The only way I got it to work was to deploy a fresh engine attached to the new storage domain, and then import the data storage domain containing the vms. The problem with that is that I lose all the settings I had in my hosted engine, and the hosts.

spice options hook
by ozmen62＠hotmail.com 21 Apr '20

21 Apr '20

Hi, We're using oVirt 4.3 and want to use spice streaming to better user experience, for example youtube etc. I've tried to use before_vm_start script, but lots of problems came out. 1 - on default environmet, hook script returns of no such file or directory, because python3 does not exist on the system if i install python3, vdsm stops working if change interpreter in the script, vdms retuns rc=0 error code hook=114 and it does not appear on the vm custom properties So, could you help me to run this hook properly we've tested https://github.com/oVirt/vdsm/tree/master/vdsm_hooks/spiceoptions Master and 4.3 branch returns same error code and nothing appeared on the "custom properties" is there anyone who is use it successfully 2 - for this experince is GPU neccessery (not vGPU) , our server has standard 8mb onboard gpu thanks

Correct workflow for modifying engine vm.conf file
by Gianluca Cecchi 21 Apr '20

21 Apr '20

Hello, I would like to know a way to interact and modify in a "supported"/working way the vm.conf file on shared storage that contains details for the engine vm and I think is the base to dynamically generate the /var/run/ovirt-hosted-engine-ha/vm.conf In the past it was possible to temporarily modify the file under /var/run (or copy to another location) and start engine with it, but now it seems it doesn't work and that the file is continuously updated/refreshed Eg on engine storage domain on a lab with oVirt 4.4. beta4 I have the tar file [root@novirt2 ~]# tar tvf /rhev/data-center/mnt/glusterSD/novirt2st.storage.local\:_engine/7c9397f5-859b-4fba-bcc5-4ecbd454a189/images/530490b0-935e-46a8-84f6-6cd6618c6f0d/2e0f414c-2589-4545-a0a4-3bfed24ef3fc -rw-r--r-- root/root 181 2020-04-19 15:04 broker.conf -rw-r--r-- root/root 2777 2020-04-19 15:04 fhanswers.conf -rw-r--r-- root/root 1076 2020-04-19 15:04 hosted-engine.conf -rw-r--r-- root/root 6 2020-04-19 15:04 version -rw-r--r-- root/root 1359 2020-04-19 15:04 vm.conf [root@novirt2 ~]# And its vm.conf has: cpuType=Cascadelake-Server,+md-clear,+mds-no,-hle,-rtm,+tsx-ctrl,+arch-capabilities I would like to modify it and remove the "+tsx-ctrl" flag. Is there anything in the database that generates modification in the file on shared storage and then on the directory under /var/run? Or how is all the workflow managed to generate at the end the xml file to use to start the engine vm? What is that initially determines how to populate the cpuType in vm.conf at all? Thanks, Gianluca

Hello, I'm trying what in subject as a nested environment. Physical is oVirt 4.3.9 I configured the VM that has to be the hypervisor with cpu passthrough. The local VM starts ok with these settings: usr/libexec/qemu-kvm -name guest=HostedEngineLocal,debug-threads=on -S -object secret,id=masterKey0,format=raw,file=/var/lib/libvirt/qemu/domain-1-HostedEngineLocal/master-key.aes -machine pc-q35-rhel8.1.0,accel=kvm,usb=off,dump-guest-core=off -cpu Cascadelake-Server,ss=on,hypervisor=on,tsc-adjust=on,umip=on,pku=on,md-clear=on,stibp=on,arch-capabilities=on,ibpb=on,rdctl-no=on,ibrs-all=on,skip-l1dfl-vmentry=on,mds-no=on,kvmclock=on When at final stage of deployment it tries to start the final engine VM it goes down due to this in vdsm.log: 2020-04-19 15:09:48,962+0200 ERROR (vm/22082519) [virt.vm] (vmId='22082519-70bb-476f-a373-45c2d402a870') The vm start process failed (vm:871) Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/vdsm/virt/vm.py", line 801, in _startUnderlyingVm self._run() File "/usr/lib/python3.6/site-packages/vdsm/virt/vm.py", line 2608, in _run dom.createWithFlags(flags) File "/usr/lib/python3.6/site-packages/vdsm/common/libvirtconnection.py", line 131, in wrapper ret = f(*args, **kwargs) File "/usr/lib/python3.6/site-packages/vdsm/common/function.py", line 94, in wrapper return func(inst, *args, **kwargs) File "/usr/lib64/python3.6/site-packages/libvirt.py", line 1166, in createWithFlags if ret == -1: raise libvirtError ('virDomainCreateWithFlags() failed', dom=self) libvirt.libvirtError: unsupported configuration: unknown CPU feature: tsx-ctrl 2020-04-19 15:09:48,962+0200 INFO (vm/22082519) [virt.vm] (vmId='22082519-70bb-476f-a373-45c2d402a870') Changed state to Down: unsupported configuration: unknown CPU feature: tsx-ctrl (code=1) (vm:1629) 2020-04-19 15:09:48,965+0200 INFO (vm/22082519) [virt.vm] (vmId='22082519-70bb-476f-a373-45c2d402a870') Stopping connection (guestagent:441) The xml it tries to activate is: <cpu match="exact"> <model>Cascadelake-Server</model> <feature name="md-clear" policy="require"/> <feature name="mds-no" policy="require"/> <feature name="hle" policy="disable"/> <feature name="rtm" policy="disable"/> <feature name="tsx-ctrl" policy="require"/> <feature name="arch-capabilities" policy="require"/> <topology cores="2" sockets="16" threads="1"/> <numa> <cell cpus="0-31" id="0" memory="16777216"/> </numa> </cpu> <os> <type arch="x86_64" machine="pc-q35-rhel8.1.0">hvm</type> <smbios mode="sysinfo"/> <bios useserial="yes"/> </os> Similar nested env with 4.3.9 on the same physical hw completed ok and the final engine VM had only: -machine pc-i440fx-rhel7.6.0,accel=kvm,usb=off,dump-guest-core=off \ -cpu Skylake-Server,spec-ctrl=on,ssbd=on,md-clear=on \ The physical cpu is: Model name: Intel(R) Xeon(R) Platinum 8260L CPU @ 2.40GHz and between its flags I don't find tsx-ctrl: Flags: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx pdpe1gb rdtscp lm constant_tsc art arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc aperfmperf eagerfpu pni pclmulqdq dtes64 monitor ds_cpl vmx smx est tm2 ssse3 sdbg fma cx16 xtpr pdcm pcid dca sse4_1 sse4_2 x2apic movbe popcnt tsc_deadline_timer aes xsave avx f16c rdrand lahf_lm abm 3dnowprefetch epb cat_l3 cdp_l3 invpcid_single intel_pt ssbd mba ibrs ibpb stibp ibrs_enhanced tpr_shadow vnmi flexpriority ept vpid fsgsbase tsc_adjust bmi1 hle avx2 smep bmi2 erms invpcid rtm cqm mpx rdt_a avx512f avx512dq rdseed adx smap clflushopt clwb avx512cd avx512bw avx512vl xsaveopt xsavec xgetbv1 cqm_llc cqm_occup_llc cqm_mbm_total cqm_mbm_local dtherm ida arat pln pts hwp hwp_act_window hwp_epp hwp_pkg_req pku ospke avx512_vnni md_clear spec_ctrl intel_stibp flush_l1d arch_capabilities any help on how to proceed and test?

Enabling VT-d causes hard lockup

Hi, I've been trying to get an old machine setup for PCIe passthrough but am seeing kernel hangs when booting into oVirt. This is a Supermicro X10DAi with dual E5-2695 V4's I think. I had VT-d enabled and added SR-IOV. Don't think there's anything else I need to enable in the BIOS is there? I just updated to the latest version for this board too. It always seems to be CPU#18 too : https://photos.app.goo.gl/HG7NcyWwfuq646HeA Shareef.
