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 27 Aug '14

27 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

VM Snapshot Problem
by Punit Dambiwal 27 Aug '14

27 Aug '14

Hi All, I am facing one strange problem with the snapshot of the VM...let me explain .... I have one vm called “vm1” & i have created the following snapshots :- 1) 2014-08-20 First Snapshot 2) 2014-08-21 Second Snapshot 3) 2014-08-22 Third Snapshot Now if i try to restore the VM(means commit) with Third Snapshot...other two snapshots will exists.. But if I restore the VM with First Snapshot...VM will restore successfully but it destroy the other 2 snapshosts (Second Snapshot & Third Snapshot)..that means both the other snapshots will be disappear.... Please let me know is this the limitation of Ovirt or it's any setting problem... Thank you.
