Migration Return Errors
by Matt Wells 14 Dec '15

14 Dec '15

We're running oVirt 3.5 in a two node setup. We've had some storage issues and getting it humming with Gluster but this seems to have all of that squared away. Our problem is peculiar and I wanted to ask the list to see if anyone else has had this. In short you can migrate a VM from one host to the other but once there it can not return to it's original host. We attempted a few things yesterday and with testing today I'll attach logs shortly. ** Environment Hosts name - Host1.example.com Host2.example.com VMs name - Server1.example.com Server2.example.com This is a hosted-enginge configuration but all seems to be working well. Even the hosted-engine shows this behavior but I'm focusing on Server 1 and 2; not the engine as I believe it complicates the tests. * Both nodes are operational with no power management setup * All VMs reside within the vm_storage mount point * At this time there is only one Network; it has the VMs and hosts. This will be broken up after this is resolved. * Server1 migrates (by hand ) from Host1 to Host2 with no issues * Server2 is powered on atop Host1 with no issues; leaving one VM on both hosts * I attempt to migrate Server1 back to Host1 and he states there is no available hypervisor * I can reboot Server2 with no issues, create a new VM on Host1 * A VM can only migrate onces, never able to return from whence it came The only way to force this is to place Host1 in maintenance mode and activate again. After this Server2 can return to Host1 but then is unable to go back to Server2; being in the same cycle

How To: Node Hosted-Engine with less then 16GB

Anything to do with ' jenkins' OVA did not work for = me, size mismatch, etc. Anytime I tried to deploy the Hosted-Engine via the Node TUI, I was not pro= mpted to adjust the amount of RAM the Hosted-Engine VM takes. (default 16G= B). After the deploy setup, the Hosted-Engine VM would not boot. When using a regular Ovirt host to deploy the Hosted-Engine, I was prompted= to adjust the RAM for the Hosted Engine! Solution : Install ovirt-engine RPMs on "host1". Install ovirt-hosted-engine-appliance RPM. Copy its OVA from /usr/share/ovi= rt-engine-appliance/ to your webserver Run hosted-engine -deploy from "host1". Adjust the RAM to 4096. Run the Hosted-Engine deploy from Node. Let it SCP the config from "host1" Reboot Host1 as make it another Node. --_000_3217552491024477ba9926bdf0e12f11GEEEX01globaleagleentco_ Content-Type: text/html; charset="us-ascii" Content-Transfer-Encoding: quoted-printable <html xmlns:v=3D"urn:schemas-microsoft-com:vml" xmlns:o=3D"urn:schemas-micr= osoft-com:office:office" xmlns:w=3D"urn:schemas-microsoft-com:office:word" = xmlns:m=3D"http://schemas.microsoft.com/office/2004/12/omml" xmlns=3D"http:= //www.w3.org/TR/REC-html40"> <head> <meta http-equiv=3D"Content-Type" content=3D"text/html; charset=3Dus-ascii"= > <meta name=3D"Generator" content=3D"Microsoft Word 15 (filtered medium)"> <style></style> </head> <body lang=3D"FR-CA" link=3D"#0563C1" vlink=3D"#954F72"> <div class=3D"WordSection1"> Here’s a short guide for = people having trouble setting up Hosted-Engine using only Ovirt Nodes.   Anything to do with ‘ jenkins&#8= 217; OVA did not work for me, size mismatch, etc.<o:p></o:p> Anytime I tried to deploy the Hosted-Engine via the Node TUI, I was not<= /i> prompted to adjust the amount of RAM the Hosted-Engine VM takes.  = (default 16GB).   After the deploy setup, the Hosted-Engine VM wo= uld not boot.  <o:p></o:p> When using a regular Ovirt host= to deploy the Hosted-Engine, I was prompted to adjust the RAM for the Hosted Engine!<o:p></o:p>= <o:p> </o:p> Solution  :<o:p></o:p></sp= an> Install ovirt-engine RPMs on &#= 8220;host1”.<o:p></o:p> Install ovirt-hosted-engine-app= liance RPM.

hosted-engine --deploy using vmfex, not bridged mode ?

I'm following some guides but I'm having trouble with the hosted-= engine --deploy section. I want to use VM-FEX to setup this initial host, as when I go bridged mode = it breaks the networking on the host and I am unable to configure/correctly= setup everything. Is there a way I can perform the hosted-engine setup using this method of t= elling it to use a vm-fex defined network pool? I might need to configure t= his myself before running hosted-engine deploy.. which is fine but I can't = touch or edit the virsh settings as there's a password - and I'm not sure h= ow to get that to modify the networking myself after the initial setup. FYI - this is the guide I'm following, as we are interested in the gluster = replication (http://community.redhat.com/blog/2014/10/up-and-running-with-o= virt-3-5/) Any suggestions/tips would be appreciated.

oVirt 3.6 and CentOS 7
by ovirt＠timmi.org 13 Dec '15

13 Dec '15

Hi oVirt users, since a couple of days I'm struggling to install oVirt 3.6 on a CentOS 7 server. Here are the steps I have done to get oVirt 3.6 engine on the host. 1. Install minimal CentOS 2. update to latest version (yum update) 3. install oVirt 3.6 (yum install ovirt-engine) 4. start rpcbind (systemctl start rpcbind) 5. run engine-setup --== CONFIGURATION PREVIEW ==-- Application mode : both Default SAN wipe after delete : False Firewall manager : firewalld Update Firewall : True Host FQDN : hostname.localdomain Engine database secured connection : False Engine database host : localhost Engine database user name : engine Engine database name : engine Engine database port : 5432 Engine database host name validation : False Engine installation : True NFS setup : True PKI organization : Me NFS export ACL : 192.168.1.0/24(rw) NFS mount point : /home/iso Configure local Engine database : True Set application as default page : True Configure Apache SSL : True Configure VMConsole Proxy : True Engine Host FQDN : hostname.localdomain Configure WebSocket Proxy : True After the successful installation of the engine I logged into the admin portal to add the host to the data center. Here I entered in the following issue: Adding the host never was successful. I found out that the firewalld was always stopped and disabled during that process. A manual start of the firewalld was allowing me to continue. After that I was able to add the storage to the server. Now I thought I will be able to install a VM into the host but it looks like that something else is missing. I have no options in the drop-down boxes of cluster, templates and OS. Is anyone able to help me here? Please note that this is my first oVirt installation. Best regards and thx Christoph

[Rest API / Python SDK] Setting VM Video Type
by Ollie Armstrong 11 Dec '15

11 Dec '15

Hi everyone, I'm looking for a method of settings the VM's video type to QXL from the Python SDK, which doesn't appear to be possible in any way. Whenever I set the graphics protocol to VNC it defaults the video type to CIRRUS. I'd like to use QXL with VNC, which is possible to set using the console's web UI. Has anyone achieved this before? Using the "SPICE + VNC" option with QXL would also be acceptable, but the API doesn't seem to accept that value for the graphics protocol. Cheers, Ollie

VM migration fails when hardware node fails

Strange permissions on Hosted Engine HA Agent log files
by Giuseppe Ragusa 10 Dec '15

10 Dec '15

Hi all, I'm installing oVirt (3.6) in self-hosted mode, hyperconverged with GlusterFS (3.7.6). I'm using the oVirt snapshot generated the night between the 18th and 19th of November, 2015. The (single, at the moment) host and the Engine are both CentOS 7.1 fully up-to-date. After ovirt-hosted-engine-setup successful completion, I found the following (about 3 days after setup completed) "anomalies": 666 1 vdsm kvm - /var/log/ovirt-hosted-engine-ha/agent.log 666 1 vdsm kvm - /var/log/ovirt-hosted-engine-ha/agent.log.2015-11-23 666 1 vdsm kvm - /var/log/ovirt-hosted-engine-ha/broker.log 666 1 vdsm kvm - /var/log/ovirt-hosted-engine-ha/broker.log.2015-11-23 The listing above comes from a custom security checking script that gives: "octal permissions" "number of links" "owner" "group" - "absolute pathname" Is the ominous "666" mark actually intended/necessary? ;-) Do I need to open a bugzilla notification for this? Many thanks in advance for your attention. Regards, Giuseppe
