[Users] Ceph RBD
by Alex T 03 Jul '13

Just wondering if there is any possibility of adding support for Ceph's RBD, I understand there are means of simply mounting an RBD with glusterfs, but for performance and simplicity adding support for creating and adding RBD's to VM's would be nice... from my experience on ubuntu 12.04 Qemu 1.4.2 is a strong recommendation. I just don't want to switch to opennebula (although probably the easiest transition from ovirt) or proxmox, kind of getting hooked on the ovirt, but it's lack of support for ceph maybe for it's direct competition with gluster is imposing on its adoption... Just some other thoughts for the developer's who seem to be few and far between (or at least according to bugzilla), providing support for debian/arch/gentoo (although they already have a little community going), I think would get alot more involvement.. Also getting the website fixed up should be asap, I mean, it is very hard to navigate, broken links, dead pages, there are tons of pages that are outdated, some that are up to date but are very difficult to navigate too... I mean you can really just copy and paste the RHEV admin manual and call it the ovirt manual, and get alot more interest, if you try and go to the ovirt admin manual now its just a dead page.... There are from what I remember 1800+ bugs and it seems that only a few developer's are actively working on them, I think that creating some better video's, with better audio showing just how simple it is to create a storage domain, create gluster volumes, iscsi domains etc.. would greatly enhance support, because lets face it, ovirt makes managing your infrastructure easy and intuitive... the more user's the bigger the community the faster the development, please port all the documentation possible from RH to Ovirt and fix up all the broken and dead links on the website so people don't think that Ovirt is a dead project, advertise all the supporter's intel, ibm, netapp whoever... if you get support in for Ceph, you beat out Citrix Vmware, Microsoft, Oracle all in one punch, everyone is looking at Ceph, ovirt is the replacement for microsofts virtual machine manager which requires a ton of things to get functional and the fact that hyper-v is a piece of crap, citrix xenserver at this level would cost around $5K per server with xendesktop and their cloud portal or whatever it's called would be over 10-20K+, VMware would be around 40-50K depending how many server's but just the storage domain option I believe is 35K, oracle I think is a little cheaper at about 3.5K per server, but not so many features... I mean ovirt has so much to offer, just need to get the word out there! I also think getting openvswitch implemented would also be a great addition to both security and functionality. Anyways, great job so far guy's, thank you very much for this software,

[Users] Ovirt-engine for Fedora 18

Hi All, I tried yum upgrade on my F18 mgmt-engine server and saw that I don't get 3.2.2. Running the following command: yum --disablerepo=* --enablerepo=ovirt-stable list shows the following (shortened) otopi.noarch 1.0.2-1.fc18 @ovirt-stable otopi-java.noarch 1.0.2-1.fc18 @ovirt-stable ovirt-engine.noarch 3.2.1-1.fc18 @ovirt-stable ovirt-engine-backend.noarch 3.2.1-1.fc18 @ovirt-stable ovirt-engine-cli.noarch 3.2.0.12-1.fc18 @updates ovirt-engine-dbscripts.noarch 3.2.1-1.fc18 @ovirt-stable ovirt-engine-dwh.noarch 3.2.0-1.fc18 @ovirt-beta ovirt-engine-genericapi.noarch 3.2.1-1.fc18 @ovirt-stable ovirt-engine-reports.noarch 3.2.0-2.fc18 @ovirt-stable ovirt-engine-restapi.noarch 3.2.1-1.fc18 @ovirt-stable ovirt-engine-sdk.noarch 3.2.0.11-1.fc18 @updates ovirt-engine-setup.noarch 3.2.2-1.1.fc18 @ovirt-stable ovirt-engine-tools.noarch 3.2.1-1.fc18 @ovirt-stable ovirt-engine-userportal.noarch 3.2.1-1.fc18 @ovirt-stable ovirt-engine-webadmin-portal.noarch 3.2.1-1.fc18 @ovirt-stable ovirt-host-deploy.noarch 1.0.2-1.fc18 @ovirt-stable ovirt-host-deploy-java.noarch 1.0.2-1.fc18 @ovirt-stable ovirt-image-uploader.noarch 3.2.2-1.fc18 @ovirt-stable ovirt-iso-uploader.noarch 3.2.2-1.fc18 @ovirt-stable ovirt-log-collector.noarch 3.2.2-1.fc18 @ovirt-stable ovirt-release-fedora.noarch 7-1 @/ovirt-release-fedora.noarch Notice the 3.2.1 ovirt-engine.noarch but the 3.2.2-1 ovirt-engine-setup. Running the same command on a Centos-6.4 engine server gives me the expected ovirt-engine-3.2.2-1.1.el6.noarch Regards, Joop -- irc: jvandewege

Re: [Users] Vlan interface on top of bonding
by Juan Pablo Lorier 02 Jul '13

Hi everyone, Thank you all, you've been very helpfull. I have one more question; How do I get a network not to be a VM network. If I create a new one, the VM option is ticked and grayed so I can't untick it. The same thing with an already created network. Sorry for all this questions, but though I've managed to find out by myself other stuff like vsdm changing multipath.conf, I haven't found much documentation on network configuration (this kind of stuff). Regards,

Hi, I am trying to switch off Hosts in DC which are idle. I wanted to know as to why start/stop of hosts options are enabled in Power Mgmt tab only when the host is in Maintenance mode and not otherwise. Also, is there any way via pythonSDK to put the host in maintenance mode ? Regards, Deepthi

[Users] Using python sdk to find the VMs running on a host.
by Deepthi Dharwar 01 Jul '13

01 Jul '13

Hi, I am using the ovirt-python-sdk to figure out if the host is idle or not. The way to determine if the host is idle at a given instant is finding out the number of VMs running on it. If the number of VMs = 0 implies host is idle. I was exploring the python sdk to figure out Host-VMs mapping i.e What are the VMs running on the different host. Looks like the only way to find this, is to query each VM in /api/vms list to get the host on which it is running. Is this the right way ? Is there no direct query or REST API to list the VMs running on a given host at that instant. I was looking to get the data center hierarchy structure. Number_of_datacenters | V clusters in each data center | V Hosts in each cluster | V VMs on each host. This kind of mapping as seen on the GUI. Is there any way to obtain the same from the ovirt-python-sdk ? With this information, this would help me write scripts to turn-off my hosts if idle automatically and power them on as required. Regards, Deepthi

[Users] too much debugging in ovirt-node
by Winfried de Heiden 01 Jul '13

01 Jul '13

Hi all, Using ovirt-node-iso-2.6.1-20120228.fc18.iso (2012 seems to be a typo, must be 2013?) is logging with too much debugging. Changing all the"DEBUG" to "WARNOMG" in /etc/vdsm/logger.conf and "persist /etc/vdsm/logger.conf" solved it for /var/log/vdsm/vdsm.log. However, /var/log/libvirtd.log also shows tons of debug messages. The file /etc/libvirt/libvirtd.conf shows: listen_addr="0.0.0.0" unix_sock_group="kvm" unix_sock_rw_perms="0770" auth_unix_rw="sasl" host_uuid="06304eff-1c91-4e1e-86e2-d773621dcab3" log_outputs="1:file:/var/log/libvirtd.log" ca_file="/etc/pki/vdsm/certs/cacert.pem" cert_file="/etc/pki/vdsm/certs/vdsmcert.pem" key_file="/etc/pki/vdsm/keys/vdsmkey.pem" Changing log_outputs="1:file:/var/log/libvirtd.log" to "log_outputs="3:file:/var/log/libvirtd.log" with persist (or unpersist first, thn persist) doesn't help. After a reboot log_outputs="1:file:/var/log/libvirtd.log" will appear again. How to decrease the log level for libvirtd? Kind regards, Winfried
