[Users] [Best practice] NFS export domain served by oVirt manager?
by Nicolas Ecarnot
Hi,
Here is a simple question about what is the best practice about the
location of a NFS export domain.
At present, I'm using a server as the oVirt manager, and this server is
also a NFS server for the ISO storage domain.
I'm using another server to serve an NFS export domain, but I'm thinking
of changing that.
Is there any advice against the decision to host the export domain NFS
on the same server as the manager?
For the time being, I will mainly use this export storage domain to
rarely import some p2v imports, but I don't need performance.
Your opinion?

[Users] oVirt and firewalld
by Jonathan Daugherty
Hi,
I've just set up a new oVirt installation with two nodes. Both of the
nodes have had 'firewalld' disabled. When I went to test VM
migration, it failed, apparently due to this (from the vdsm log on the
source node):
error : virNetClientProgramDispatchError:174 : Error while building
firewall: Some rules could not be created for interface vnet0:
Failure to execute command '$EBT -t nat -N libvirt-J-vnet0' :
'DBusException org.freedesktop.DBus.Error.ServiceUnknown: The name
org.fedoraproject.FirewallD1 was not provided by any .service
filesCouldn't connect to FirewallD, it's probably not running.'.
Is running firewalld a requirement for oVirt? Is it possible to avoid
having oVirt attempt to manage my firewall rules?
Thanks!

[Users] Add NIC directly to VM (Dedicated)
by Matt .
Hi,
For setting up a firewall in a VM I would like to add 2 of my 4 nics
directly to a VM.
In my previous setup I thought I have done that, but at the moment I cannot
figure this out and cannot find the docs to accomplish this.
I would like to dedicate those 2 nics to my firewall VM's to avoid sharing
them using a network per accident to other VM's.
How is this be done at the moment ?
Cheers,
Matt

[Users] Engine location best practice?
by Lance A. Brown
I'm setting up an oVirt environment at $WORK and trying to decide where
to locate the ovirt-engine. Is it better practice to put it on a
separate computer from the nodes? If I co-locate it on a node machine,
then I have to worry about it being unavailable if that node is down.
How much of an issue is that likely to be?
Thanks,

[Users] ovirt-shell: Disabling autopage
by Adam Litke
Hi,
Currently the ovirt-shell displays command results using a pager. It does this
even when running non-interactively (ie. input via pipe) which is broken. As a
workaround, I discovered the option 'cli:autopage = False' should be placed in
my .ovirtshellrc file. This works great the first time, but then it seems
ovirt-shell is overwriting this file and dumping my new setting. What am I
doing wrong here?

[Users] Internet Explorer with latest master
by Dead Horse
Ever since this change: http://gerrit.ovirt.org/#/c/11078/
The webadmin and userportal UI no longer displays nor works correctly
within Internet Explorer 8 or 9.
Under IE 8 or 9 the UI is pretty much an usable garbled mess. Everything
looks and works fine under Chrome and Firefox.
Unfortunately Internet Exploder is a necessary evil for windows users to
be able to get at SPICE consoles. (No spice plugin/support for
Firefox/Chrome yet...)

[Users] GlusterFS configuration and performance question

Hi,
We're planning to migrate from iSCSI /LVM to mirrored GlusterFS to reach fa=
il-over.
As I did read here<http://community.gluster.org/q/can-i-use-glusterfs-as-an=
-alternative-network-storage-backing-for-vm-hosting/> GlusterFS isn't actua=
lly the best solution for big VM images?
(by the way what means big here?)
Does anybody here can share his experience with using GlusterFS,
how many VMs are running and what is the expected IO per second for a VM ?
(I know this can differ enormously)
We have about
Perhaps somebody here already uses 3.3 (with self-healing) ?
I'm pretty looking forward to GlusterFS 3.4, as the new features seem to be=
"made" for RHEV/oVirt.
Thanks in advance for your feedback!
Best, Sven.

[Users] full screen and different resolutions with spice
by Gianluca Cecchi
Let me know if I had better to post to spice-devel....
I'm testing oVirt 3.2 beta user portal.
One client boots from a usb stick running SLAX 32bit in persistent
mode with kernel 3.6.9.
It is a derivative from slackware 14 where I compiled and persistently installed
spice-protocol-0.12.2-noarch-1
xf86-video-qxl-0.1.0-i486-1
celt051-0.5.1.3-i486-1
pyparsing-1.5.6-i486-1
spice-0.12.0-i486-1
vala-0.17.6-i486-1
gtk-vnc-0.5.1-i486-2
virt-viewer-0.5.4-i486-1
xulrunner-15.0.1-i486-1
jdk-7u13-i586-1
spice-xpi-2.8-i486-1
so far so good.
I can start firefox 17.0.1 and connect to user portal
The test VM is Windows XP
There was previously a session from another client pc with full screen
resolution of 1366x768.
Now this other client PC has a max resolution of 1024x768
I notice that it fails to start in full screen (I get the typical
window where you see that the screen is bigger than the current
physical) and also the Shift+F11 shortcut doesn't get any effect or
error.
If inside the vm I now set 1024x768 it adjusts and I can set full
screen with Shift+F11 and I now can disconnect and reconnect
successfully in fullscreen option.
Then I close spice window and sign out from user portal (leaving the
VM at its logged in screen)
If now I connect again to the user portal from the 1366x768 capable
client, that is Fedora 17 with firefox 18.0 and
spice-gtk-python-0.12-5.fc17.x86_64
spice-xpi-2.8-2.fc17.x86_64
spice-server-0.10.1-5.fc17.x86_64
spice-gtk-tools-0.12-5.fc17.x86_64
spice-client-0.10.1-5.fc17.x86_64
spice-vdagent-0.10.1-1.fc17.x86_64
spice-gtk-0.12-5.fc17.x86_64
spice-glib-0.12-5.fc17.x86_64
spice-gtk3-0.12-5.fc17.x86_64
I connect in full screen mode and I see the Windows XP session just
starts in 1024x768 (as I left it) and suddenly adjusts to the 1366x768
capable resolution
Any hint on why the fiirst auto-adjust didn't work?
- different spice version?
- perhaps only possible to up scale but not down scale?
- other?
This will address situation with one user potentially connecting to
the same VM in full screen mode but using different clients and so
with possible different video resolutions
A work around could be to power off the vm each time but it is not desirable...
Also, in Fedora I get the small box at top middle of the screen where
I can exit full screen for my vm. Instead in slax I have not it.
WHat is the component providing that box?
Thanks for all
