[Users] [Best practice] NFS export domain served by oVirt manager?
by Nicolas Ecarnot 15 Feb '13

15 Feb '13

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? -- Nicolas Ecarnot

[Users] oVirt and firewalld
by Jonathan Daugherty 15 Feb '13

15 Feb '13

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! -- Jonathan Daugherty Software Engineer Galois, Inc.

[Users] Add NIC directly to VM (Dedicated)
by Matt . 15 Feb '13

15 Feb '13

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 15 Feb '13

15 Feb '13

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, --[Lance]

[Users] ovirt-shell: Disabling autopage
by Adam Litke 15 Feb '13

15 Feb '13

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? -- Adam Litke <agl(a)us.ibm.com> IBM Linux Technology Center

[Users] Internet Explorer with latest master
by Dead Horse 14 Feb '13

14 Feb '13

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...) - DHC

[Users] NFS Advanced Parameters Greyed out on Existing Storage Domains
by Chris Noffsinger 14 Feb '13

14 Feb '13

So I have read this BZ https://bugzilla.redhat.com/show_bug.cgi?id=855729 and these related ovirt BZs http://gerrit.ovirt.org/#/c/8110/ http://gerrit.ovirt.org/#/c/8797/ http://gerrit.ovirt.org/#/c/8798/ So forgive me but I am a little confused. I have some existing NFS Storage domains that I was not paying attention and attached without doing any advanced parameters in RHEV 3.1 Now the NFS Advanced Parameters box is greyed out. So now that I have attached these domains I cannot change the advanced nfs option such as change it to Nfs4 from 3 or rsize and wsize? Maybe if I was using upstream oVirt instead of Rhev 3.1 I would be able to make the changes in vdsm.conf and they would be honored? -- Chris Noffsinger

[Users] full screen and different resolutions with spice
by Gianluca Cecchi 14 Feb '13

14 Feb '13

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 Gianluca
