BSoD in windows servers V.M due the processor Class
by Carlos Castillo 08 Aug '14

08 Aug '14

The subject of this email possibly suggest that I'm publishing in the wrong place but I'm not. I'm would like try to see if anyone faced a similar situation with Windows VM's. Since the beginning of week 2 of my database servers (oVirt's VM's), are presenting a BSoD (STOP) because of a bugfix 0x00000101 CLOCK_WATCHDOG_TIMEOUT. After analyzing the minidump and make some review I found that this problem commonly occurs on Windows Server 2008 R2 installed in machine's with Intel processors Nehalan class (Xeon 5675 as we have in our solution). 99% of our Windows VM's run Windows 2008 R2, and although the situation has now generated only 2 servers affectation I wonder if exists some procedure to solve or a way to mask the processor type in the virtual machines. Thanks in advance -- Carlos J. Castillo ---------------------------------------------------------------------------------- Ingeniero de Soluciones de TI +58 426 2542313 @Dr4g0nKn1ght

User Portal "Open in Full Screen"
by Sigbjorn Lie 07 Aug '14

07 Aug '14

Hi, In version 3.3 the "Open in Full Screen" under Spice Console Options in the User Portal was not enabled by default. In version 3.4 the "Open in Full Screen" is now enabled by default. Is it possible to manage the default behaviour of this setting? I would like it *not* to be enabled by default. Regards, Siggi

Kernel panic for live images
by Jaco 07 Aug '14

07 Aug '14

Hi folks, I get kernel panics when booting the live images: * ovirt-live-3.4.0.el6ev.iso (MD5: 01a83d96a9650dd3da19cc37edaa7b19) * ovirt-live-el6-3.4.3-1.iso (MD5: 816fd6b1294f4619e205f2efd92f0f2f) I've run Memtest86 (v2.01) & it checks out OK, the current CentOS 6.5 on the host runs OK & live-booting other images (either LiveUSB or PXE, CentOS, Fedora, Debian, Ubuntu & other) works fine. Has anyone else gotten this? Just seeking confirmation that it's not just me before filing a bug. I believe a new images may become available after the testing this week. Will try earlier images to compare. - J

Is there a plan to allow VM migration?
by John Gardeniers 06 Aug '14

06 Aug '14

As per the subject, is there a plan to allow VM migration? By that I don't mean the current idea of detaching the export storage and attaching it to another compatible system. I mean a real migration to something external to the system the VM is currently on. At least in my universe, there are times when it is highly desirable or even necessary to take an Ovirt/RHEV VM and move or copy it to another system, such as between completely separate Ovirt/RHEV systems or to other systems such as KVM/Qemu or VirtualBox. The nearest I can manage right now is to use an imaging tool to make a copy of the drive and import that into the destination machine. That's slow, cumbersome and still requires the VMs configuration to be manually duplicated. regards, John

Hi Sven, Regarding the ticket "path", Is it the direct combination of host and port ? suppose if the host is 1.2.3.4 and the port is 5100 then what should be the "path" value ? Is there encryption needs here ? >>so you have access from the browser to the websocket-proxy, network wise? can you ping the proxy? and the websocket proxy can reach the host where the vm runs? yes.. there should be no firewall issue as we can access the console from ovirt engine portal Do we need to allow our own portal ip address in the ovirt engine and hypervisiors also ??? -- Regards Shanil On Wed, Jul 16, 2014 at 3:13 PM, Sven Kieske <S.Kieske(a)mittwald.de> wrote: > > > Am 16.07.2014 11:30, schrieb Shanil S: > > We will get the ticket details like host,port and password from the > ticket > > api funcion call but didn't get the "path" value.

The oVirt team is pleased to announce that the 3.5.0 First Release Candidate is now available for testing as of Aug 5th 2014. The release candidate is available now for Fedora 19, Fedora 20 and Red Hat Enterprise Linux 6.5 (or similar) and allow you to use Red Hat Enterprise Linux 7 as node and run Hosted Engine. Feel free to join us testing it on Tue Aug 12th third test day! This release of oVirt includes numerous bug fixes. See the release notes [1] for a list of the new features and bugs fixed. The existing repository ovirt-3.5-pre has been updated for delivering this release without the need of enabling any other repository. If you're already using ovirt repository on EL7, please update ovirt-release3.5 rpm, it will provide additional repositories for it. Please refer to release notes [1] for Installation / Upgrade instructions. New oVirt Live, oVirt Guest Tools and oVirt Node ISO will be available soon as well[2]. Please note that mirrors may need a couple of days before being synchronized. If you want to be sure to use latest rpms and don't want to wait for the mirrors, you can edit /etc/yum.repos.d/ovirt-3.5.repo commenting the mirror line and removing the comment on baseurl line. Known issues in this RC: - Bug 1124099 - Live Merge: Limit merge operations based on hosts' capabilities - ovirt-optimizer has not been updated for EL6 due to dependencies issues - vdsm for EL7 is missing a couple of patches compared to other distro due to building issues [1] http://www.ovirt.org/OVirt_3.5_Release_Notes [2] http://resources.ovirt.org/pub/ovirt-3.5-pre/iso/ -- Sandro Bonazzola Better technology. Faster innovation. Powered by community collaboration. See how it works at redhat.com

backup.sh fails
by Niklas Fondberg 04 Aug '14

04 Aug '14

Hi all, I might be of a tangent but I tried to follow the steps in http://www.ovirt.org/User_talk:Stkeimond/Backing_Up_And_Restoring_OVirt for a backup. I get an error because of the postgres user password that I never set in the installation of oVirt (as far as I know.) Does anyone know of another way to backup or is this a bug/fault_by_me? The command line and error is: [root@dl380 dbscripts]# ./backup.sh -u postgres -l /mnt/msa60/backups/ Backup of database engine to /mnt/msa60/backups//engine_Mon_Jul_14_16:50:45_CEST_2014.sql started... pg_dump: [archiver (db)] connection to database "engine" failed: FATAL: Ident authentication failed for user "postgres" pg_dump: *** aborted because of error Backup of database engine failed.

Lowering cluster CPU level : safe?
by Nicolas Ecarnot 04 Aug '14

04 Aug '14

Hi, I'm trying to add some Westmere hosts into a Sandybridge cluster, and of course, they get refused : "Host xxxxxxxxx moved to Non-Operational state as host does not meet the cluster's minimum CPU level. Missing CPU features : model_SandyBridge" I tried to lower the cluster level but I get this warning : "Change Cluster CPU level There are running VMs. Lowering the Cluster CPU level might prevent migration of these VMs to some of the Hosts in the Cluster. Are you sure you want to continue?" As a frightened chicken, I clicked "Cancel" and turned to you : how safe is it to lower the CPU level? I understand some instructions will be missing, and maybe performance will change, but we don't have heavy CPU usage yet, so this may not be a big issue. I was wondering what will happen to my existing VMs? Will I have to modify some setup? What may prevent migration between westmere and sandybridge hosts? Regards, -- Nicolas Ecarnot

RAID Expanded
by Neil 04 Aug '14

04 Aug '14

Hi guys, I'm running oVirt 3.3 with an FC SAN. I had 12x500GB LUNS and these were all assigned to my data domain. Once the new volumes have finally finished syncing on the SAN, will oVirt automatically see the new LUNS, or is there anything that needs to be done in order to see them? I'm just trying to prepare for when things finally finish. Thank you. Regards. Neil Wilson.

ilo4 vs. ipmilan fencing agents
by Jason Brooks 04 Aug '14

04 Aug '14

Hi all -- I'm trying to get fencing squared away in my cluster of hp dl-380 servers, which come with ilo4. I was able to get a successful status check from the command line with fence_ilo4, but not w/ the ilo4 option in ovirt. I see, though, that ilo4 in ovirt just maps to fence_ipmilan, and I was not able to get a successful status check w/ fence_ipmilan from the cli. So, I tried resetting the mapping so that ilo4 maps to ilo4. Now I can complete the power management test in ovirt, but I imagine there's some reason why ovirt isn't configured this way by default. Will fencing actually work for me with ilo4 mapped to ilo4, rather than to ipmilan? Thanks, Jason --- Jason Brooks Red Hat Open Source and Standards @jasonbrooks | @redhatopen http://community.redhat.com

Can keys be set up for engine-iso-uploader and engine-img-uploader?
by Dwight Schauer 04 Aug '14

04 Aug '14

Hello Ovirt users, Is there a way for automated processes outside of Ovirt to use engine-iso-uploader and engine-img-uploader without requiring the admin password to be inserted? I would rather not have to deal with passwords in automated processes and I was hoping there was a cleaner solution (keys, certs, etc). -- Dwight Schauer
