Hello Dan, Nevermind. After 2 months I had some time to look at this problem again but didn't remember I put the server in maintenance mode. I put it in maintenance mode to install updates and doublecheck all configuration and apparently I did something wright as it just works now. Kind regards. 2014-08-28 16:34 GMT+02:00 Andy Michielsen <andy.michielsen(a)gmail.com>: > Hello Dan, > > I can't find a clue in the engine.log but I'm unable to start any VM on > this host. > Looks like it lost its connection to its datadomain entirely. > > Kind regards. > > > 2014-08-28 15:12 GMT+02:00 Dan Kenigsberg <danken(a)redhat.com>: > > On Thu, Aug 28, 2014 at 02:14:07PM +0200, Andy Michielsen wrote: >> > Dear all, >> > >> > I need some help.

Moving a POSIX storage domain to be a Local Storage
by Elad Shmitanka 28 Aug '14

28 Aug '14

Hi, In the initial setup I wasn't aware of the option to assign a local disk as Local Storage and we have added it as a POSIX complaint Storage Domain, now that we want to add a new KVM host, it needs to attach the storage domain to the new host, which it obviously can't. My question is, how do I remove the Storage domain and add it back as a Local storage without harming the VMs that are already on the system (obviously some downtime will be needed) I guess that I can add another Storage Domain and start moving them to a "temp location" and then back, question is if there is another quicker way.

iSCSI self hosted engine
by Markus Mathes 28 Aug '14

28 Aug '14

Hi, I thought about a self hosted engine setup using 2 hosts connected to a iSCSI storage. A few questions arose and I didn't succeed finding the answers on the web. I somehow don't get how the iSCSI integration in ovirt works. - As far as I understand from the information I found, all iSCSI access for the virtual machines is done through one host. Does this mean, that all disk related traffic of the other host is going to the first host and then to the iSCSI storage? In this case. How are the virtual disk images then made available for the VMs on the other host? - If the first host fails, the engine will get started on the other host. Will the engine deal with the fact, that now the iSCSI storage domain has to be accessed using the other host. Or is iSCSI just not suitable for this kind of usage. - Has the self hosted engine to use a different iSCSI lun than the storage domain? Thanks Markus -- ************************************************** Markus Mathes, PhD Product Development www.dectris.com **************************************************

Network question: mirrored port?
by Chris Adams 28 Aug '14

28 Aug '14

I have a couple of traffic-monitoring servers that get a copy of all traffic on a VLAN via a mirrored port on the switch, connected to a dedicated port on each server. Is there a good way to run that type of traffic into a VM? -- Chris Adams <cma(a)cmadams.net>

info about ovirtmgmt bridge config in master
by Gianluca Cecchi 27 Aug '14

27 Aug '14

Hello, I'm configuring an all-in-one environment in a Qemu-KVM VM with CentOS 6.5 using nested virtualization. All seems ok except the hypervisor part that goes in timeout during setup and after reboot remains in "Unassigned" state. I notice that under /etc/sysconfig/network-scripts directory I don't have the ifcfg-ovirtmgmt file but only the old ifcfg-eth0 and in fact I only have bridge [root@ovirtita ~]# brctl show bridge name bridge id STP enabled interfaces ;vdsmdummy; 8000.000000000000 no Ha anything changed for master and ovirtmgmt network or does this mean that during setup something has gone wrong and that I can try to manually create ovirtmgmt bridge config...? If this can interfer, in my case I don't have dns set up but only entry in /etc/hosts. With previous versions and this one I got a warning but previously this didn't compromise hypervisor part in all-in-one environments.. engine-setup log https://drive.google.com/file/d/0BwoPbcrMv8mvQVRyZXFqdFpCbnM/edit?usp=shari… host deploy (on itself) part: https://drive.google.com/file/d/0BwoPbcrMv8mvLXhlMl9qcWhqTlU/edit?usp=shari… Thanks Gianluca

Ovirt and Fedora 20
by Jamie Bohr 27 Aug '14

27 Aug '14

I followed the instructions on http://www.ovirt.org/Quick_Start_Guide#Install_oVirt_Engine_.28Fedora_.2F_R… for installing ovirt on a Fedora 20 instance. I expanded jboss-as-web-7.0.2.Final into /opt/jboss-as-web-7.0.2.Final and ran "engine-setup --jboss-home=/opt/jboss-as-web-7.0.2.Final". Everything appeared fine however the web interface will not start, the following appear in the console.log file: Could not load Logmanager "org.jboss.logmanager" I looked for that error in reference to ovirt but did not find anything relevant, hoping someone on this list can point me in the right direction. Sorry if this was double posted, it was not in my sent item and it was late yesterday when I thought I sent it. -- Jamie Bohr
