[Users] persisting selinux nightmare
by David Smith 21 Feb '14

21 Feb '14

I'm using the ovirt iso image and can't seem to get selinux to persist off no matter what i do. With selinux enforcing, SSHD isnt working, can't install or use the hosts. With it disabled, all seems to work, but after reboot, boom its enforcing again. I even edited /etc/selinux/config and changed it to permissive, then used "persist config" to persist the file. I reboot, I see the file is still changed, but selinux is back into enforcing mode (getenforce) what gives? I'm using this iso image, is this the latest one? It seems really hard to navigate the various old links in docs and such to find the most up to date isos. ovirt-node-iso-3.0.3-1.1.vdsm.fc19.iso

[Users] Host Non-Operational from sanlock and VM fails to migrate
by Trey Dockendorf 21 Feb '14

21 Feb '14

I have a 2 node oVirt 3.3.2 cluster setup and am evaluating the setup for production use on our HPC system for managing our VM infrastructure. Currently I'm trying to utilize our DDR InfiniBand fabric for the storage domains in oVirt using NFS over RDMA. I've noticed some unstable behavior and it seems in every case to begin with sanlock. The ovirt web admin interface shows the following message as first sign of trouble on 2014-Feb-03 07:45. "Invalid status on Data Center Default. Setting Data Center status to Non Responsive (On host vm01.brazos.tamu.edu, Error: Network error during communication with the Host.).". The single VM I had running is stuck in the "Migrating From" state. virsh shows the VM paused on the crashed host and the one it attempted to migrate to. Right now I have a few concerns. 1) The cause of the sanlock (or other instability) and if it's related to a bug or an issue using NFSoRDMA. 2) Why the VM failed to migrate if the second host had no issues. If the first host is down should the VM be considered offline and booted on the second host after first is fenced? Attached are logs from the failed host (vm01) and the healthy host (vm02) as well as engine. The failed host's /var/log/message is also attached (vm01_message.log). Thanks - Trey

[Users] oVirt 3.4 pre-release and GlusterFS support (F19)
by Brad House 20 Feb '14

20 Feb '14

I've been testing the 3.4 prerelease on Fedora 19. When I create a GlusterFS (not POSIXFS) storage group and create a VM with a disk image on the storage group, I see a POSIX mount created on the host. Upon further investigation, when evaluating the executed qemu command line, it doesn't appear qemu is being told to use libgfapi but rather that previously observed POSIX mount. One other note, I'm specifically testing the hosted engine, and haven't tested using the non-hosted variant. The question is .... is this expected behavior, and if so, is it because of the hosted engine? Or is this some form of regression from the advertised feature list of oVirt 3.3? Anything I should try or look at? I'm obviously concerned about the FUSE overhead with Gluster and would like to avoid that if possible. Thanks! -Brad

[Users] Why choose glusterfs over iscsi for oVirt storage?
by Justin Clacherty 20 Feb '14

--_000_C79B906B4ECB8E46A3281AC932C805502F49039Aexchangeredfish_ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Hi, I'm just setting up some storage for use with oVirt and am wondering why I = might choose glusterfs rather than just exporting a raid array as iscsi. T= he oVirt team seem to be pushing gluster (though that could just be because= it's a Red Hat product). Can anyone answer this one? What I have come up with is as follows. For: - easy to expand - redundancy across storage devices/easy replication - high availablility - performance - it's kind of cool :) - maintenance? Against (these are guesses): - performance? (multiple layers of filesystems everywhere - fs in = vm + image on gluster + gluster + block filesystem) - complexity - maintenance? Any help here is appreciated. Also, does the underlying block level filesy= stem matter here? VMs running under ovirt would be typical business applic= ations - file serving (samba4), email, databases, web servers, etc. Cheers, Justin. --_000_C79B906B4ECB8E46A3281AC932C805502F49039Aexchangeredfish_ 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=3DContent-Type content= =3D"text/html; charset=3Dus-ascii"><meta name=3DGenerator content=3D"Micros= oft Word 15 (filtered medium)"><style></style></head><body lang=3DEN-AU link=3D"#0563C1= " vlink=3D"#954F72"><div class=3DWordSection1>Hi,<o:p>= </o:p><o:p> </o:p>I&= #8217;m just setting up some storage for use with oVirt and am wondering wh= y I might choose glusterfs rather than just exporting a raid array as iscsi= .  The oVirt team seem to be pushing gluster (though that could just b= e because it’s a Red Hat product).  Can anyone answer this one?<= o:p></o:p><o:p> </o:p>What I have come up with is as follows.<o:p></o:p><o:p> </o:p>For:<o:p></o:p><![if= !supportLists]>-          <= /span><![endif]>easy to expand<o:p></o:p><![if !supportLi= sts]>-          </spa= n><![endif]>redundancy across storage devices/easy replication<o:p></o:p></= p><![if !supportLists]>-      &nbsp= ;   <![endif]>high availablility<o:p></o:p><![if !supportLists]>-        =   <![endif]>performance<o:p></o:p><![if !supp= ortLists]>-          = <![endif]>it’s kind of cool J<o:p></o:p><![if !supportLists]>-  &nbsp= ;       <![endif]>maintenance?<= o:p></o:p><o:p> </o:p>Against (these are guesses):<o:p></o:p><![if !supportLists]><s= pan style=3D'mso-list:Ignore'>-          <![en= dif]>performance?

[Users] API read-only access / roles
by Sander Grendelman 20 Feb '14

20 Feb '14

I'm working on (Zabbix) monitoring through the RESTful API. Which role should I assign to the monitoring user? The user only needs read access to the data but it looks like I nead to assign at least an "Admin" role to the user to be able to read data through the API. For this I've created a "AdminLoginOnly" role that only has System->Configure System->Login Permissions access. Is this the way to go for this king of configuration? Or is there a way to further minimize the permissions of this user? Another issue is that a "Login" event is generated every time the user connects through the API. This makes the "Events" pane less useful / readable. Is there a way to disable this for some users/roles?
