[Users] RAID1 mirror on ovirt-node + engine nfs server
by Jason Keltz 09 Jul '13

09 Jul '13

Hi. I've been reading about ovirt, and ready to try my own experiments with it. I have two small questions.. When an ovirt-node is installed from the standard ISO, there's no mention in the documentation about setting up a RAID1 mirror for the root disk on the node. I'm sure that once I get around to working out kickstarting the node, I could easily install the raid1 mirror, but I'm just wondering why I don't see that in the default ISO. Maybe I'm just missing something. Is redundancy of the disk on the node not important? Sure, if the node goes down, I guess the VMs could be run on other nodes, but if we can prevent the node from going down in the first place, then why not? I also have a question about the storage backend. In particular, I have a pretty powerful server that I intend to use as the NFS server, and a few servers to use as nodes. On the other hand, I don't have a powerful machine (at the moment) to use for the ovirt-engine. Would it be poor practice to run the ovirt-engine ON the NFS server? During engine setup, I see that you can setup an NFS share for ISOs from the ovirt-engine, but I don't think there's mention of just generalized storage there. I suspect it's "poor practice", but I thought I'd ask anyway. My setup will be relatively small (say, 4 nodes), and this would let me reduce 1 general server from the infrastructure (dedicated ovirt-engine). Thanks! :) Jason. ps: At the moment, I am not subscribed to users - please cc: me on responses.

[Users] libgovirt 0.2.0
by Christophe Fergeau 08 Jul '13

--hoZxPH4CaxYzWscb Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Hey, I've just made a new release of libgovirt. libgovirt is a GObject C library to access oVirt/RHEV[1] REST API[2]. At the moment, it's able to get the list of VMs available on an oVirt instance, and to get the connection details for a given VM. This release mainly consists of internal refactoring to make it easier to support new parts of oVirt REST API, and to get it to work with older glib versions. However, it also has minor API breaks, and changes the library soname because of ABI breakage. It can be downloaded from http://people.freedesktop.org/~teuf/govirt/libgovirt-0.2.0.tar.xz It's signed with my GPG key: A525 E3EA 186A AB45 DD0F 86AF 24A4 69FB 7A56 F78E Changes since 0.1.0 - Rename OvirtVm::uuid to OvirtVm::guid to match oVirt terminology - Break ABI :( - Switch back to using GSimpleAsyncResult (from GTask) to gain compatibility with older glib versions - Refactor internals to make it much easier to add support for more REST collections - Parse more VM states from the OvirtVm resource Christophe [1] http://www.ovirt.org/Home [2] https://access.redhat.com/site/documentation//en-US/Red_Hat_Enterprise_Virt… --hoZxPH4CaxYzWscb Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.13 (GNU/Linux) iEYEARECAAYFAlHal+cACgkQJKRp+3pW9462dgCcDtQXNqPSLW9JA6LX6Zy4GCUb bNUAnA5OStLSLs1bZxRaQl+kYo32S21Y =fbuI -----END PGP SIGNATURE----- --hoZxPH4CaxYzWscb--

Nor is support for mdraid devices, to be honest. It's something worth considering (whether btrfs redundancy or mdraid), but it's not currently implemented to my knowledge. I could be wrong about that. I also have a question about the storage backend. In particular, I have > a pretty powerful server that I intend to use as the NFS server, and a > few servers to use as nodes.

This is definitely a workable use case, especially for small environments.

[Users] Network setup with bonded vlan tagged interfaces only

--Boundary_(ID_BXXGSt4FBfZW7Pnv2D/KdA) Content-type: text/plain; CHARSET=US-ASCII; format=flowed Content-transfer-encoding: 7BIT Hi I am very new to oVirt and stumple accross some issues. Maybe I am doing something wrong. I have only one server right now which should be the engine + the host. The host network has been setup like the following: bond0 (Prod network bonding) bond0.110 (Prod VLAN) with ip 10.0.10.30 (I connect to the server with that address) bond1 (Storage bonding) bond1.130 (Storage VLAN) with ip 10.0.30.30 (used for iscsi communication) I have other vlans which I should use: VLAN 100 - reserved vor oVirt Management VLAN 120 - DMZ VLAN 140 - LAB Do I need to create bond0.xxx files for each of them? Or do I create the networks inside ovirt gui and vlan tag them? How should I configure ovirtmgmt interface? It has to go through bond0 and with vlan 100. I would very appreciate if one could explain me what the proper setup would look like for such a setup.

Hello, I am trying to install ovirt using the Live CD Image located at http://resources.ovirt.org/releases/3.2/tools/ovirt-live-1.0.iso but the install to HDD menu is prompting for root password? Could someone please point me to the root password for the installation of oVirt using install to HDD menu? Best Regards, Moto
