[Users] Getting Started with oVirt 3.3
Hi! Published a book about oVirt - Getting Started with oVirt 3.3 Getting Started with oVirt 3.3 has a tutorial-based approach to learning oVirt KVM virtualization. This book will introduce you to the various components of the oVirt engine and will show you how to implement virtualization. Getting Started with oVirt 3.3 talks you through the internal structure and working of oVirt 3.3 using a practical, hands-on approach. You will learn how to install and set up your own virtualization infrastructure as well as in what order you should configure your virtualization environment, what features oVirt has, and how to use them. You will also learn how easy it is to create cluster policies to control the operation of a cluster as well as how to create and use a virtual machine template. -- Alexey Lesovsky http://www.thislinux.org ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Re: [Users] ovirtmgmt not installed
As a matter of fact, when I installed F19, it created an eno1 device,
aliased to em1. Don't know why, yet.
Even adding a GATEWAY clause in /etc/sysconfig/network does not seem to
change the problem
Will check how to change the device name.

Subject: Re: ovirtmgmt not installed
Mike
Here you go. However, please note that I must investigate the connection
issue that Alon saw. will do it tomorrow.
Many thanks to you folks.
P
According to the output of 'nics' element, the 'em1' device is missing his
default gateway entry under the 'cfg' element.
One reason for that can be there is no
'/etc/sysconfig/network-scripts/ifcfg-em1'
file and vdsm fails to obtain the default gateway for it.
Could you create this file by your own and retry installing the host ?
After creating the file (make sure it contains NM_CONTROLLED=no), restart
the network service
and run 'vdsClient -s 0 getVdsCaps' to make sure 'em1' output contains the
data its 'cfg' sub-
element.

[Users] Public glance image repository for oVirt
Hi Everyone I thought of adding a new public Glance image repository on oVirt.org, to be used in different oVirt environments. The nice thing about glance compared to current export domain is that it can be attached to multiple oVirt environments / data centers, so it can be a public image repository everyone can use. Would you see such a repository as useful? Would you use it? What type of images/virtual appliances would you find beneficial to have there? If you're interested let me know. If we see enough traction for it then I'll set it up. Thank you, Oved ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

I've just tried to install this latest oVirt node image again and made

After pressing close I'm then back at the 'Keyboard layout selection'

If I then press enter on 'US international' then tab down to the option

get an error on the install progress screen - at the 40% point.
The error reads:

image and have tried installing it on two separate machines.
Whether I do a regular install (default boot screen option) or choose
'reinstall' from the troubleshooting menu I get tripped up at the same spot.
When it comes time to select a keyboard layout (I think this is correct)
US English is the default. I press enter at that point and after a
short delay there is a very uninformative error message that appears. I
can't remember what it is off the top of my head and the systems are at
work (I'm at home now).
After this point I can continue but the install fails immediately after
I get past the install target selection screen.
Has anyone successfully installed a node using this iso image?
I even tried removing partitions from the drive beforehand, to the point
of dd'ing the first 512 bytes to make sure there was no partition table.
This didn't help - I still ran into the install error described above.
I particularly wanted to try an FC19 based node to try out live storage
migration on NFS, as I was having problems with the EL6.4 node with this.
Is there a chance that that issue might be resolved for EL6 based nodes
by an upcoming new EL6.5 based node spin?
Sorry I cannot provide the exact error details for the install issue
now, but I can get the error detail in the next couple of days if required.
Thanks,
Paul
This time the install seems to work.
Unfortunately when it comes up the SSH service doesn't seem to be
working. When I try and ssh to the machine I get the following:
Read from socket failed: Connection reset by peer
The above was after configuring the node for an Ovirt engine, accepting
the certificate and entering a password.
The ovirt web GUI shows this node as non responsive.

[Users] CentOS upgrade from 3.2 to 3.3
Hi all! Just wanted to express my deepest admiration for the progress of this project. You may or may not remember my quest for upgrading from 3.1 to 3.2 and just how difficult a seemingly trivial thing can turn out to be quite the ordeal... This time around, we followed this post by dreyou on how to go from his 3.2-repo to the ovirt.org stable repo 3.3: http://wiki.dreyou.org/dokuwiki/doku.php?id=ovirt_rpm_start33 And the whole process _just worked_! Something that actually made me even more nervous, left me feeling like OK, so this is going just too well, I´ve got a bad feeling about this...:) But no, nothing ever blew us out the sky and the entire process of upgrading the engine and six hosts went through in just under the hour from start to finish! Best part is of course that our customers VM´s never even noticed; a completely live upgrade. Awesome! I mean, I worked my ass off trying to go from 3.1 to 3.2, I´ve actually put a mental block on the actual time it took, but probably six months of planning and trial and error, to have this done in under an hour...

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. That is a way to use oVirt, but the following simple setup should work and give you a way to check against your setup. I have two setups, one at home and one at work. The one at home is a setup of 2 hosts and one of those is a hacked up host/engine. engine/host1: standard fedora19 kde install, static ip (192.168.1.11) configured with my NAS (192.168.1.16) as dhcp/dns server and my internet router (192.168.1.254) as gateway Just make sure that NetworkManager is off and that your interfaces are not NM managed, network on. This was a allinone setup but I got a NAS with NFS so I turned my aio setup into a engine/host system. It has problems with that but nothing network related. Host2: same as above but without the engine install, ip:192.168.1.22, gw 192.168.1.254 DNS:192.168.1.16. How does it all come together? Well in your case, and mine if I were to start over, start with a static network which is NOT managed by NetworkManager. Use either Fedora or Centos which ever you more comfortable with and it also depends on whether you want to test/use all the features in oVirt. Currently, there are a few features not available in Centos because the versions of libvirt/kvm/qemu/gluster are too old in Centos. Install ovirt-engine on your first 'server', probably choose NFS as your storage domain, either on your engine server or from somewhere else on your network. Make sure its nfs-v3 and not v4!, local default is v4! Make sure that ip addresses on you network are resolvable, either through /etc/hosts or through DNS! Engine-setup will complain if this doesn't work, using localhost will not work either! On the engine server there will be no bridge and nothing will change the network config. Next the first host. Prepare the host in a similar way you did the engine server. You can choose a minimal install of either Centos or Fedora or install a full desktop but make sure that ips are static and NOT managed by NetworkManager, hostname resolvable, ovirt repo available. From the webui add your prepared host and if everything went OK you'll see that on that host you will now have a bridge, ovirtmgmt, which acts as the primary interface. Create a VMs and choose ovirtmgmt as a network for its nics, can't choose anything else. Either give the VMs a static address or use a dhcp server but the VMs should be able to talk to each other, to the host(s), the engine and to the internet. Every host that you add after the first will also has its network turned into a bridge, ovirtmgmt, and communication/migration/display/etc will take place over this network. One caveat, storage domain mapping is from the host to the storage, the engine, if it is NOT the NFS server, doesn't have to have access to the storage. If you have servers with more that 1 nic then you can create additional networks using the webui of oVirt and assign these to clusters and to VMs. If you need vlans to coexist with ovirtmgmt on the same physical nic, I think that is possible but haven't tried it myself. In theory you need to setup the network first outside of oVirt, including you vlan structure and then install ovirt. Some concepts: oVirt engine: is just the manager, does 'nothing' related to running VMs itself. You can turn it off and all hosts with their VMs will keep running. You just can't start new ones, in short manage them. oVirt host: is the real workhorse and is managed using oVirt-engine. Runs VDSM which communicates with engine and starts/manages the VMs on the host on behalf of engine. oVirt node: is a special slimmed down Fedora distro that includes VDSM and a small setup so that it can be used as a oVirt host People tend to mix and match ovirt-host and ovirt-node which makes for nice communication problems :-) If you haven't done so, there is an irc channel, ovirt, on irc.oftc.net with helpful people, if they are awake. Joop -- #irc jvandewege When I get another project out of the way (hopefully this week), I will be able to get back to my test setup and try again.

What reason is there that networks are so divided? Yes there is lack of documentation in this area, it's a shame but given it's an open source project with an open wiki, everyone is invited to contribute and improve this. I'll see if I can get a page started.. Please post a link if you succeed. 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. Not sure what you mean by all these restrictions, from what I know the firewall rules that are set on each host are to allow host to talk to engine (ssh, vdsm, VM consoles traffic, etc) no more no less.. Usually the default behavior of firewall is to block almost all communication so when you add a host and check the Configure firewall box it modifies it so that your host can function properly. I need my host to be on my LAN (for multiple reasons). Ovirtmgt stole the LAN connection, and cut off the host from the LAN, a connection which worked fine until then. oVirt has no sense of firewall otherwise. For all it cares you can turn it off completely, or configure it by yourself (manually or via puppet/chef/foreman/etc) and not use the capability of the system to configure it for you. How do I keep the engine from reconfiguring the firewall again if I change it manually? I saw a blog post that mentioned being able to uncheck a box (on the o-virt web GUI) called configure IPTables. That /might/ be what I need. I didn't see that box, but I wasn't looking for it (and at the moment I don't have o-virt available to me). You can also change it so that it uses the rules you want by modifying IPTablesConfig via engine-config tool. Where can I find documentation on changing firewall rules using engine-config? From what I understand, I want my LAN to be my non-VLAN bridge. Can I move the ovirtmgt functionality to run over the LAN, or can I/will I have to put ovirt-mgt onto a VLAN? 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. Your VMs will be sitting on the ovirtmgmt network, or on a VLAN? I want them to sit on the LAN (which may be ovirtmgt, if I can get the IP filtering turned off). If they have to be on something else too, that is OK, as long as it does not interfere with them being on the LAN. FYI, the LANs on both of my applications are fairly small. One of them less than 10 nodes, the other less than 20 nodes,

Hi Ted, I've lost the beggining of the thread so excuse me if I'm wrong about the topic. Do you want to get all the vms and host in the same subnet as the rest of your lan or the hole collision domain? When you create the logical networks (LN) in ovirt you can check if they are required or not. If you decide that all your hosts must give access to some subnet for vm use, you can create a LN, mark it as required in your data center (DC) and configure it in every host you have in the dc. Then you have two choices, if you just want the vms to access that subnet, add it to the host without configuring the ip on the host and you'll just get a bridge for vm use. If you want the host to use the bridge also, configure the ip and you'll get both, vms and host to be in the subnet. If what you need is to get every vm access to the hole collision domain, then I don't think you can do it in ovirt as you get a bridge for every logical network and if you have both, tagged and untagged vlan traffic, you won't be able use the same nic (or bond) to place mixed LNs (a limitation I've rised but yet haven't been resolved). Hope this helps. Regards, ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

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. That is a way to use oVirt, but the following simple setup should work and give you a way to check against your setup. I have two setups, one at home and one at work. The one at home is a setup of 2 hosts and one of those is a hacked up host/engine. engine/host1: standard fedora19 kde install, static ip (192.168.1.11) configured with my NAS (192.168.1.16) as dhcp/dns server and my internet router (192.168.1.254) as gateway Just make sure that NetworkManager is off and that your interfaces are not NM managed, network on. This was a allinone setup but I got a NAS with NFS so I turned my aio setup into a engine/host system. It has problems with that but nothing network related. Host2: same as above but without the engine install, ip:192.168.1.22, gw 192.168.1.254 DNS:192.168.1.16. How does it all come together? Well in your case, and mine if I were to start over, start with a static network which is NOT managed by NetworkManager. Use either Fedora or Centos which ever you more comfortable with and it also depends on whether you want to test/use all the features in oVirt. Currently, there are a few features not available in Centos because the versions of libvirt/kvm/qemu/gluster are too old in Centos. Install ovirt-engine on your first 'server', probably choose NFS as your storage domain, either on your engine server or from somewhere else on your network. Make sure its nfs-v3 and not v4!, local default is v4! Make sure that ip addresses on you network are resolvable, either through /etc/hosts or through DNS! Engine-setup will complain if this doesn't work, using localhost will not work either! On the engine server there will be no bridge and nothing will change the network config. Next the first host. Prepare the host in a similar way you did the engine server. You can choose a minimal install of either Centos or Fedora or install a full desktop but make sure that ips are static and NOT managed by NetworkManager, hostname resolvable, ovirt repo available. From the webui add your prepared host and if everything went OK you'll see that on that host you will now have a bridge, ovirtmgmt, which acts as the primary interface. Create a VMs and choose ovirtmgmt as a network for its nics, can't choose anything else. Either give the VMs a static address or use a dhcp server but the VMs should be able to talk to each other, to the host(s), the engine and to the internet. Every host that you add after the first will also has its network turned into a bridge, ovirtmgmt, and communication/migration/display/etc will take place over this network. One caveat, storage domain mapping is from the host to the storage, the engine, if it is NOT the NFS server, doesn't have to have access to the storage. If you have servers with more that 1 nic then you can create additional networks using the webui of oVirt and assign these to clusters and to VMs. If you need vlans to coexist with ovirtmgmt on the same physical nic, I think that is possible but haven't tried it myself. In theory you need to setup the network first outside of oVirt, including you vlan structure and then install ovirt. Some concepts: oVirt engine: is just the manager, does 'nothing' related to running VMs itself. You can turn it off and all hosts with their VMs will keep running. You just can't start new ones, in short manage them. oVirt host: is the real workhorse and is managed using oVirt-engine. Runs VDSM which communicates with engine and starts/manages the VMs on the host on behalf of engine. oVirt node: is a special slimmed down Fedora distro that includes VDSM and a small setup so that it can be used as a oVirt host People tend to mix and match ovirt-host and ovirt-node which makes for nice communication problems :-) If you haven't done so, there is an irc channel, ovirt, on irc.oftc.net with helpful people, if they are awake.

Between your info, something I stumbled onto on a blog, and the info from Mike, I hope to have enough to make some progress when I take another stab at it. I'd just like to reiterate what has

Re: [Users] How to pxeboot ovrit node into memory automatically?

Hey David, the stateless mode is currently not completely working with oVirt Engine. That means a Node needs to be approved each time it boots into the stateless mode. The stateless mode can be entered by appending stateless to the default kernel arguments. Greetings fabian ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
[Users] Rhel 6.5 Released = libgfapi?
Hi all, I noticed rhel 6.5 was released and now most centos mirrors have been updated: http://lists.centos.org/pipermail/centos-announce/2013-December/020032.html It appears to have a new version of qemu-kvm-0.12.1.2-2.415.el6.x86_64.rpm Is it now possible to switch from POSIX to native glusterfs? If so, how would one do that, I assume it requires some sort of database hack. Thanks, Andrew ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
