[Users] hosted engine setup (NFS)
by René Koch
Hi,
I installed hosted engine and faced an issue with NFS during installation.
First of all, I'm using GlusterFS on my storage and ovirt engine doesn't
support GlusterFS yet, only NFS.
But for NFS I can't use mountprotpo=tcp as hosted-engine --setup doesn't
ask for NFS options.
So I manually edited the following file:
/usr/share/ovirt-hosted-engine-setup/plugins/ovirt-hosted-engine-setup/storage/storage.py
and changed opts.append('vers=3'):
if domain_type == 'nfs3':
fstype = 'nfs'
opts.append('vers=3,mountproto=tcp')
My question is now: is it possible to ask for NFS options during setup
or do you think this can lead into problems? NFS via TCP worked fine for
me for one week until I rebooted the host today (did reboot tests last
weeks, too which was fine) and can't start hosted engine anymore (see
other mail thread), but I think the other issue is not NFS mountproto
related.

Disable auth basic in API
by Jose Manuel Marquez Alhambra
Hi,
I’m testing a connection broker that uses oVirt's API. At the moment, the connection broker doesn’t work because it doesn’t send the basic authentication to oVirt's API. I contacted the developers and they're investigating the error. While they solve the error, I would like to continue testing the connection broker. Is there any way to disable auth basic in oVirt's API?
I’m using it in a testing environment (oVirt 3.4 at CentOS 6), so I’m not worried about security risks.
Thank you.
Regards,
Jose

minimum DNS requirements for /etc/hosts
by Jeremiah Jahn
So like the nut job I am, I host my dns server on a virtual machine
that is now hosted by ovirt, I also have a few gateway machine in
there as well for routing traffic between internal networks. With
virt-manager, DNS rarely seemed to be an issue. I'd connect to a host
IP, and bring up the vm, no problem. Ovirt on the other hand takes
forever if dns is down. So i've passed around a /etc/hosts file to
resolve any ip address that ovirt might be looking for while dns is
out. I'd like to verify at an abstract level, what needs to be in
said file, to keep everything from timing out, or just taking forever.
name and FQDN of each host
name and FQDN of engine host
name and FQDN of each storage domain.
Is this enough, or are there other places/things the ovirt node and
hosts might be trying to resolve?
thanks,
-jj-

Re: [ovirt-users] minimum DNS requirements for /etc/hosts
by Jeremiah Jahn
I only use names for storage, but didn't have entries for the engine
yet, So I think ssh was slow since it couldn't do reverse DNS lookups
against the engine where my consoles are coming from. Thanks for the
input. I wanted to verify before testing since this is a production
environment. It seems like even the XMLRPC code must try and do a
reverse DNS against the engine as well, not just ssh. Seems like the
engine hosts also needs said hosts file as well..

yes, storage info are stored in /etc/ovirt-hosted-engine/hosted-engine.conf.
By the way, if you want to propagate the info on new hypervisors when you run deploy on them, you should also update the answer file in
/etc/ovirt-hosted-engine/answers.conf so it will be configured automatically in newly installed hypervisors

Re: [Users] 2 virtual monitors for Fedora guest
by Gianluca Cecchi
Some prelimianry tests at my side.
oVirt 3.4 on fedora 19 AIO.
Datacenter and cluster configured as 3.4 level
Some packages on it
libvirt-1.1.3.2-1.fc19.x86_64
qemu-kvm-1.6.1-2.fc19.x86_64
vdsm-4.14.6-0.fc19.x86_64
spice-server-0.12.4-3.fc19.x86_64
guest is an updated Fedora 19 system configured based on blank
template and OS=Linux
and
xorg-x11-drv-qxl-0.1.1-3.fc19.x86_64
spice-vdagent-0.14.0-5.fc19.x86_64
Client is an updated Fedora 20 box with virt-viewer-0.6.0-1.fc20.x86_64
If I select the "Single PCI" checkbox in console options of guest and
connect from the Fedora 20 client I don't see at all an option in
remote-viewer to open a second display and no new display detected in
guest.
And lspci on guest indeed gives only one video controller.
BTW: what is this option for, apart the meaning?
If I deselect the "Single PCI" checkbox I get the "Display 2" option
in remote-viewer but it is greyed out.
No new monitor in "detect displays" of guest.
In this last situation I have on host this qem-kvm command line:

dependency error when upgrade ovirt 3.3 -> 3.4 (CentOS)
by H. Haven Liu
Hello,
I'm trying to upgrade an ovirt 3.3 installation to 3.4, but getting a dependency error. I tried to update the ovirt-engine-setup package to v 3.4.0-1.el6, which requires ovirt-engine-setup-plugin-ovirt-engine = 3.4.0-1.el6, which requires ovirt-engine >= 3.3.2. However, it appears that ovirt-engine 3.3 is in the versionlock list and cannot be updated. Should I manually disable the versionlock plugin, or am I missing something?
Thanks,
Haven
