[Users] simple networking?
by Ted Miller 16 Dec '13

16 Dec '13

I am trying to set up a testing network using o-virt, but the networking is refusing to cooperate. I am testing for possible use in two different production setups. My previous experience has been with VMWare. I have always set up a single bridged network on each host. All my hosts, VMs, and non-VM computers were peers on the LAN. They could all talk to each other, and things worked very well. There was a firewall/gateway that provided access to the Internet, and hosts, VMs, and could all communicate with the Internet as needed. o-virt seems to be compartmentalizing things beyond all reason. Is there any way to set up simple networking, so ALL computers can see each other? Is there anywhere that describes the philosophy behind the networking setup? What reason is there that networks are so divided? After banging my head against the wall trying to configure just one host, I am very frustrated. I have spent several HOURS Googling for a coherent explanation of how/why networking is supposed to work, but only fine obscure references like "letting non-VMs see VM traffic would be a huge security violation". I have no concept of what king of an installation the o-virt designers have in mind, but it is obviously worlds different from what I am trying to do. The best I can tell, o-virt networking works like this (at least when you have only one NIC): there must be an ovirtmgt network, which cannot be combined with any other network. the ovirtmgt network cannot talk to VMs (unless that VM is running the engine) the ovirtmgt network can only talk to hosts, not to other non-VM computers a VM network can talk only to VMs cannot talk to hosts cannot talk to non-VMs hosts cannot talk to my LAN hosts cannot talk to VMs VMs cannot talk to my LAN All of the above are enforced by a boatload of firewall rules that o-virt puts into every host and VM under its jurisdiction. All of the above is inferred from things I Googled, because I can't find anywhere that explains what or how things are supposed to work--only things telling people WHAT THEY CANT DO. All I see on the mailing lists is people getting their hands slapped because they are trying to do SIMPLE SETUPS that should work, but don't (due to either design restrictions or software bugs). My use case A: * My (2 or 3) hosts have only one physical NIC. * My VMs exist to provide services to non-VM computers. * The VMs do not run X-windows, but they provide GUI programs to non-VMs via "ssh -X" connections. * MY VMs need access to storage that is shared with hosts and non-VMs on the LAN. Is there some way to TURN OFF network control in o-virt? My systems are small and static. I can hand-configure the networking a whole lot easier than I can deal with o-virt (as I have used it so far). Mostly I would need to be able to turn off the firewall rules on both hosts and VMs. banging head against wall, Ted

[Users] Upgrade from 3.3.1-2 el6 to 3.3.2
by Sven Kieske 16 Dec '13

16 Dec '13

Hi, got a question regarding engine upgrades: My current setup: I got 3.3.1-2.el6 installed from ovirt-beta repo and want to upgrade to 3.3.2 RC. According to: http://www.ovirt.org/OVirt_3.3.2_release_notes "oVirt 3.3.2 release candidate is available for testing. In order to install it you've to enable ovirt-updates-testing repository." I need ovirt-updates-testing enabled? Shall I disable ovirt-beta repo? Additional info: the base os is still CentOS 6.4 Did anyone perform an inplace upgrade to 6.5? Is this recommended? -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.

[Users] Documentation incoming
by Sven Kieske 16 Dec '13

16 Dec '13

Hi, just for all who are curious: There is a large package of documentation for oVirt at redhat.com: https://access.redhat.com/site/documentation/Red_Hat_Enterprise_Virtualizat… There is also beta documentation for 3.3. This is more structured than the ovirt.org wiki. Maybe this helps someone. PS: In case you do not know: Red Hat Enterprise Virtualization (RHEV for short) is a downstream product build from oVirt, so almost everything in the docs should be transferable to oVirt. -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.

[Users] all-in-one: adding nodes, HA
by Vesa Alho 16 Dec '13

16 Dec '13

Hi, I've been searching archives, but didn't find a definitive answers so decided to ask here. Question 1: all-in-one: adding nodes In case I use all-in-one installation, is it possible to add more nodes? I would be using shared iSCSI storage. What I understand, in order to use multiple physical servers, I need to dedicate one for management? Question 2: High Availability What I need to do in practice to get high availability between two virtual machines? I tried to search for guides. Do I need setup some watchdog devices and daemons? -Mr. Vesa Alho BTW, does Ovirt FAQ exists yet? My questions would be basic FAQ material. I can help out with Wiki if needed.

[Users] [Bug] Ubuntu 12.04.3 LTS Server does not start with CD attached
by Sven Kieske 16 Dec '13

16 Dec '13

Hi, I created a BZ with very detailed information: https://bugzilla.redhat.com/show_bug.cgi?id=1038121 tl;dr: The above mentioned OS does not start correctly if you attach a cd-rom to it, this includes submitting meta-data via Cloud-Init. The System hangs during the boot-process. I couldn't reproduce this with Ubuntu 13.10, but I have to get Ubuntu 12.04 LTS running with Cloud-Init. I did not find any hint in the Ubuntu log files to the causes of behaviour. You find most of the relevant log files in the BZ. The System boots fine if you eject the cd via webadmin. It seems not to get removed automatically when you shutdown the machine. Did anybody else run into this issue? Any help would be appreciated. -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.

Re: [Users] moving ovirt controller
by Vered Volansky 16 Dec '13

Hi Rob, What you need to do is upgrade the engine using engine-setup and the SHA of the version you want. If you have the rpm for the newer version use it with engine-seyup. If not, you'll have to build on your own, the use engine-setup. Then you can migrate the DB. This, BTW, is highly not recommended, though this is the way to work. It's recommended to work with stable versions. Let me know us this works for you.
