Change local DC host address
by Alexandr Krivulya 18 Aug '16

18 Aug '16

Hi! There is any way to change host address in a local DC? In web-ui it's grayed out, ovirt-shell gives an error: status: 400 reason: Bad Request detail: Host Address can not be modified due to Security restrictions. In order to change Host Address, Host has to be reinstalled Reinstall host is not a solution with local DC.

Is hosted engine supported in hosts with diff CPU types?
by Fredy Sanchez 18 Aug '16

18 Aug '16

Hi all, I am deploying hosted engine in what will hopefully become our 4th oVirt cluster. The engine is up and running happily in host 1 already, but I am running into the following when running hosted-engine --deploy in hosts 2 and 3: The following CPU types are supported by this host: - model_Opteron_G3: AMD Opteron G3 - model_Opteron_G2: AMD Opteron G2 - model_Opteron_G1: AMD Opteron G1 [ ERROR ] Failed to execute stage 'Environment customization': Invalid CPU type specified: model_SandyBridge Host 1 has an Intel chip. Hosts 2 and 3 have an AMD chip. Is this a supported config? If so, how can I bypass the error? Thank you very much. Cheers, Fredy

Ovirt 4.0 Login Issue
by Melissa Mesler 17 Aug '16

17 Aug '16

I am running 4.0 on CentOS 7.2. Sometimes when I first log in to the admin page, it will give me and error that says "Request state does not match session state." Then if I go through the process of logging in again, it will go through with no issue. It doesn't do this every time but it does do it quite often. Any ideas on why? - MeLLy

Upgrade hosts/nodes from engine
by Hanson 17 Aug '16

17 Aug '16

Hi Guys, Quick question, I have my nodes on a bond-bridge-privateVlan setup, and my engine on a bond-bridge-publicVlan setup for remote monitoring. Understandably, the nodes are complaining that they are failing updates. (They're on a private vlan, and only configured with IP's in that vlan, the public vlan doesn't have IP's set on the hosts so they can pass it to VMs). Is there a way to have the engine do the updates on the node using its internet connection, like a proxy? For security reasons I like to have the nodes not publicly accessible, as we see hundreds if not thousands of ssh attempts, and root would probably be the most attacked account. Thanks, Hanson

Gluster replication on 1Gb interfaces
by Fernando Frediani 16 Aug '16

16 Aug '16

Hi all. I understand using 10Gb interfaces when using Gluster is advised for helping with data replication specially in situations where a node went down for a while and need to re-sync data. However can anyone tell if using one 1Gb interface dedicated for it in hosts with 1.8 TB of Raw storage would be still Ok or can it cause severe impact on performance ? What are the chances of a 1Gb nice being saturated during normal operation ? Thanks Fernando

edit gluster storage domain
by Edward Clay 16 Aug '16

16 Aug '16

Hello, I need to edit a glusterfs storage domain to add the mount option " backupvolfile-server=SERVER" So when the primary servers IP is not accessible the remaining servers will be used to retrieve data stored on the gluster volume. Right now when I try to edit the storage domain the mount options box is grayed out and not editable. I recently had to take all vms down so I put the HV in maintenance mode and the edit options wasn't present. I need to understand if this is the correct option to make a glusterfs volume fault tolerant? Also I need to understand how to make this edit in the ovirt web interface or other method. TIA

oVirt 4 with custom SSL-certificate and SPICE HTML5 browser client -> WebSocket error: Can't connect to websocket on URL: wss://ovirt.engine.fqdn:6100/

Hello oVirt guru`s ! I have successfully replaced the oVirt 4 site SSL-certificate according to the instructions from "Replacing oVirt SSL Certificate" section in "oVirt Administration Guide" http://www.ovirt.org/documentation/admin-guide/administration-guide/ 3 files have been replaced: /etc/pki/ovirt-engine/certs/apache.cer /etc/pki/ovirt-engine/keys/apache.key.nopass /etc/pki/ovirt-engine/apache-ca.pem Now the oVirt site using my certificate and everything works fine, but when I try to use SPICE HTML5 browser client in Firefox or Chrome I see a gray screen and message under the button "Toggle messages output": WebSocket error: Can't connect to websocket on URL: wss://ovirt.engine.fqdn:6100/eyJ...0=[object Event] Before replacing certificates SPICE HTML5 browser client works. Native SPICE client works fine. Tell me what to do with SPICE HTML5 browser client?

Hello, I'm confused because though I'm using ovirt-shell to script many actions every day, and even after a large bunch of reading and testing, I can not find the correct syntax to move (offline/available) disks between storage domains. May you help me please? (oVirt 3.4.4) -- Nicolas Ecarnot

oVirt 4.0 and multipath.conf for HPE 3PAR. What do you advise?
by aleksey.maksimov＠it-kb.ru 16 Aug '16

16 Aug '16

Hello, oVirt guru's ! I installed oVirt 4.0 on several servers HP ProLiant DL360 G5 with QLogic/Emulex 4G dual-port HBAs. These servers have multipath connection to the storage system HP 3PAR 7200. Before installing oVirt to servers I set up the configuration file /etc/multipath.conf according to the vendor recommendations from document "HPE 3PAR Red Hat Enterprise Linux and Oracle Linux Implementation Guide (emr_na-c04448818-9.pdf)" https://blog.it-kb.ru/2016/06/12/configuring-device-mapper-multipathing-dm-… Before installing oVirt my multipath.conf was the: ---> start of /etc/multipath.conf <----- defaults { polling_interval 10 user_friendly_names no find_multipaths yes } blacklist { devnode "^cciss\/c[0-9]d[0-9]*" } multipaths { multipath { wwid 360002ac000000000000000160000cec9 alias 3par-vv2 } multipath { wwid 360002ac000000000000000170000cec9 alias 3par-vv1 } } devices { device { vendor "3PARdata" product "VV" path_grouping_policy group_by_prio path_selector "round-robin 0" path_checker tur features "0" hardware_handler "1 alua" prio alua failback immediate rr_weight uniform no_path_retry 18 rr_min_io_rq 1 detect_prio yes } } ---> end of /etc/multipath.conf <----- But after installing oVirt file multipath.conf has changed to: ---> start of /etc/multipath.conf <----- defaults { polling_interval 5 no_path_retry fail user_friendly_names no flush_on_last_del yes fast_io_fail_tmo 5 dev_loss_tmo 30 max_fds 4096 } devices { device { all_devs yes no_path_retry fail } } ---> end of /etc/multipath.conf <----- Now I'm not sure that this configuration is optimal. What do you advise?

Short SSL key sizes, and TLS 1.2 on vdsm
by Chris H 15 Aug '16

15 Aug '16

Hello, My RHEVM hypervisors (Red Hat Enterprise Virtualization Hypervisor release 7.2 (20160627.3.el7ev)) are failing corporate Nessus TCP/IP vulnerability scans spectacularly with the following. 1) "SSL Certificate Chain Contains RSA Keys Less Than 2048 bits": many ports in the 5900 range are presenting certificates signed by a key of 1024 bits. I can certainly see 1024-bit keys on the management server and the hypervisors: management ovirt-engine]# openssl x509 -in ca.pem -noout -text | grep Public-Key Public-Key: (1024 bit) hypervisor admin]# openssl x509 -in /etc/pki/vdsm/certs/cacert.pem -noout -text | grep Public-Key Public-Key: (1024 bit) Can anyone point me at directions on how to regenerate the key(s) with 2048 bits, and all certificates, preferably without breaking anything? The management server is running RHEL 6.8, rhevm-3.6.7.5. 2) "TLS Version 1.2 Protocol Detection": Port 54321 is failing because it doesn't support TLS v1.2 (and also because its certificate's key is less than 2048 bits). This port is used by "/usr/bin/python /usr/share/vdsm/vdsm". Can I enable TLS v1.2 in vdsm? It doesn't have to accept TLSv1.2 exclusively, it just has to have v1.2 available (and NOT SSLv2 or 3). If I firewall off these ports, I can't connect to VMs' consoles anymore, so hiding from the scanner isn't feasible for long. Please help point me in the right direction. Thanks, Chris -- *The Starflyer is real!*

LDAP-based domain not working after upgrade?
by Nicolás 15 Aug '16

15 Aug '16

Hi, We're running oVirt 4.0.1.1, and we're trying to grant a permission to a user on a VM. Thing is when we open the 'Permissions' subtab on that VM, we click on Add, the LDAP backend shows up but any value entered into the search box returns nothing, even when I know the values exist. This has been working on oVirt 3.x, we actually migrated to 4.x last week and didn't notice this issue. Additionally, there's no combobox to choose the permission to grant? All this is done with the admin@internal user, so I guess this is not a self-permission issue. Interesting thing is that I can successfully log-in to the user portal with a LDAP based user and manage all the VMs assigned to them. Just to see if there's been any configuration change, we also run the ovirt-engine-extension-aaa-ldap-setup tool, the configuration it returns is pretty similar to ours, and even the test commands (Login, Search) work successfully (I can see search returning user's data like name, surname, ...). We even applied this configuration to engine to see if it makes a difference but the result is the same, the search dialog returns nothing and neither I can see the permission to grant. Any hint about this? Thanks

Move VM disks from gluster storage to local storage
by Siavash Safi 14 Aug '16

14 Aug '16

Hi, An unknown bug broke our gluster storage (dom_md/ids is corrupted) and oVirt no longer activates the storage(I tried to recover it using the similar issues reported in mailing list but it didn't work). As I checked VM disk images are still accessible when I mount the gluster storage manually. How can we manually move the VM disk images to local storage? (oVirt complains about gluster storage being inactive when using the web interface for move/copy) Thanks, Siavash

LVM2 Thinprovisioned
by Fernando Frediani 14 Aug '16

14 Aug '16

Hello all. When you use oVirt with a Block Storage the only option available to store de VMs is LVM. Does LVM in oVirt use Thinprovisoned (supported in LVM2) instead of having to use the SAN Thinprovisioned features ? Fernando

General system updates policy
by David Gossage 14 Aug '16

14 Aug '16

Is it considered safe from an ovirt stability standpoint to apply yum updates to the hosts and engine as centos/redhat release them? For example the recent https://rhn.redhat.com/errata/RHSA-2016-1606.html update for qemu. If I run yum update and update that is their any worry for me that it has not been tested with oVirt and so versions will break something. Same with kernels, libraries etc.. *David Gossage* *Carousel Checks Inc. | System Administrator* *Office* 708.613.2284
