Qemu-kvm-rhev packages and gluster
by Joop 12 Jul '14

12 Jul '14

Just installed these packages on a test cluster and I'm having problems migrating VMs :-( Looking at the libvirt logs shows that there is a port conflict (49153) when migrating. Looks like libvirt is using glusterfs ports for migratiio and yes there is a BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1009100 This problem isn't there when using the std el6 qemu-kvm packages but I need gluster AND migration so it seems I'm stuck until somebody 'fixes' the build in jenkens.

I am running it on a HP DL380 with an external SAS chassi. Linux dist is Centos 6.5 and oVirt is 3.4 running all-in-one (for now until= we need to have a second host). Our company (www.vireone.com) deals with system architecture for many telco= and media operators and is now setting up a small own datacenter for our i= nternal tests as well as our IT infrastructure. We are in the process of installing Zentyal for the SMB purposes on a guest= and it would be great to have that guest also serving a fs path directory = with NFS + SMB (which is semi crippled on the host after oVirt installation= with version 3 et.c.). Does anyone have an idea of how I can through oVirt (seen several solutions= using virsh and kvm) letting my Zentyal Ubuntu guest have access to a host= mount point or if necessary (second best) a seperate partition?

Dashboard tab in Administration Portal displays a message only "Specified page not found"

Hi. I noticed one important thing is that the service does not start ovirt-engine-dwhd. I have no idea why this happens. I tried to look for some logs for this service, but nothing. If you have any idea where to look or what to do, I'd be grateful. Grzegorz

You could alse extract the system-uuid if its different between systems. No guarantee though that all bios vendors make there systems unique. Joop

Problem with hosted engine setup on VLAN/bond combo
by Chris Adams 11 Jul '14

11 Jul '14

I am trying to install oVirt with the hosted engine. The physical system is CentOS 6.5 x86_64 (with all current updates). It is connected to a two-switch stack via bond0 (running LACP), which is a VLAN trunk, and the management interface is vlan51. This doesn't work with oVirt 3.4.2, but I see that both 3.4.3 and 3.5 have "support engine on bond" and "support engine on vlan" in the release notes, so I tried again with today's 3.4.3 RC. I got a different error from "hosted-engine --deploy": [ ERROR ] Failed to execute stage 'Misc configuration': Command '/usr/bin/vdsClient' failed to execute I see this in /var/log/vdsm/supervdsm.log: ######################################################################## MainProcess|Thread-16::INFO::2014-07-10 10:20:23,003::configNetwork::275::root::(addNetwork) Adding network ovirtmgmt with vlan=51, bonding=None, nics=['bond0'], bondingOptions=None, mtu=None, bridged=True, defaultRoute=True,options={'bootproto': 'static', 'ONBOOT': 'yes'} MainProcess|Thread-16::ERROR::2014-07-10 10:20:23,003::supervdsmServer::100::SuperVdsm.ServerCallback::(wrapper) Error in addNetwork Traceback (most recent call last): File "/usr/share/vdsm/supervdsmServer", line 98, in wrapper res = func(*args, **kwargs) File "/usr/share/vdsm/supervdsmServer", line 190, in addNetwork return configNetwork.addNetwork(bridge, **options) File "/usr/share/vdsm/configNetwork.py", line 186, in wrapped return func(*args, **kwargs) File "/usr/share/vdsm/configNetwork.py", line 287, in addNetwork blockingdhcp=blockingdhcp, **options) File "/usr/share/vdsm/configNetwork.py", line 121, in objectivizeNetwork topNetDev = Nic(nic, configurator, mtu=mtu, _netinfo=_netinfo) File "/usr/share/vdsm/netmodels.py", line 80, in __init__ raise ConfigNetworkError(ne.ERR_BAD_NIC, 'unknown nic: %s' % name) ConfigNetworkError: (23, 'unknown nic: bond0') ######################################################################## Is there maybe still a problem combining a VLAN on a bond? A little background (if it helps): this is my first attempt with oVirt. I'm installing on a clean CentOS install on a spare box, with the intent to get oVirt up and running and then convert (one node at a time) an existing VM setup (running old stand-alone Xen installs) to oVirt. -- Chris Adams <cma(a)cmadams.net>

[ANN] oVirt 3.5.0 Second Alpha is now available for testing
by Sandro Bonazzola 11 Jul '14

11 Jul '14

The oVirt team is pleased to announce that the 3.5.0 Second Alpha is now available for testing. Feel free to join us testing it! You'll find all needed info for installing it on the release notes page, already available on the wiki [1]. A new oVirt Live iso is already available for testing[2] including all available updates from CentOS. An oVirt Guest Tools iso is now available too[3]. A new oVirt Node build will be available soon as well. Please note that mirrors will 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 You can't add hosts to 3.5 clusters until a new VDSM build with 3.5 compatibility level will be released (All in One won't work).
