[Users] Glance with oVirt
by Riccardo Brunetti 10 Oct '13

10 Oct '13

Dear ovirt users. I'm trying to setup an oVirt 3.3 installation using an already existing OpenStack glance service as an external provider. When I define the external provider, I put: Openstack Image as "Type" the glance service endpoint as "URL" (ie. http://xx.xx.xx.xx:9292) I used the openstack public url. check "Requires Authentication" put the administrator user/password/tenant in the following fields. Unfortunately the connection test always fails and the glance provider doesn't work in ovirt. In the engine.log I can see: 2013-09-24 15:57:30,665 INFO [org.ovirt.engine.core.bll.provider.TestProviderConnectivityCommand] (ajp--127.0.0.1-8702-3) Running command: TestProviderConnectivityCommand internal: false.

The glance URL is reachable from the oVirt engine host, but looking with tcpdump on the glance service I noticed that no connections come up --- when I use "requires authentication" --- a connection happens if --- I do not use "requires authentication" --- (even if the test fails ultimately) My OS is CentOS-6.4 and my packages are the following: [root@rhvmgr03 ovirt-engine]# rpm -qa | grep ovi ovirt-host-deploy-1.1.1-1.el6.noarch ovirt-log-collector-3.3.0-1.el6.noarch ovirt-engine-cli-3.3.0.4-1.el6.noarch ovirt-engine-webadmin-portal-3.3.0-4.el6.noarch ovirt-engine-tools-3.3.0-4.el6.noarch ovirt-release-el6-8-1.noarch ovirt-engine-sdk-python-3.3.0.6-1.el6.noarch ovirt-iso-uploader-3.3.0-1.el6.noarch ovirt-host-deploy-java-1.1.1-1.el6.noarch ovirt-engine-userportal-3.3.0-4.el6.noarch ovirt-engine-backend-3.3.0-4.el6.noarch ovirt-engine-setup-3.3.0-4.el6.noarch ovirt-engine-3.3.0-4.el6.noarch ovirt-image-uploader-3.3.0-1.el6.noarch ovirt-engine-lib-3.3.0-4.el6.noarch ovirt-engine-restapi-3.3.0-4.el6.noarch ovirt-engine-dbscripts-3.3.0-4.el6.noarch Do you have some suggestion to debug or solve this issue?

[Users] Cannot set disk interface in user portal
by Dead Horse 08 Oct '13

08 Oct '13

The Add disk UI in the User Portal does not populate the interface pull-down. Nor will it allow the creation of a new virtual disk as a result. The error states insufficient permissions however the user is assigned PowerUserRole at the cluster level and on the associated storage domain(s).

--_000_7fbb63dfa18c4b05af73e117062f6f83BN1PR04MB170namprd04pro_ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Hello All, I've been searching the archives and not yet managed to find anything on th= e subject, so I'm hoping that someone can point me in the right direction. I am using nodes with Intel 10G network cards. The driver for these cards = has been tweaked to complain (and fail to start the interface) if a non-Int= el approved optical transceiver is in use. It's easy to override with the = following options: ixgbe.allow_unsupported_sfp=3D1 The usual ways of doing this are either to place it on the kernel command l= ine at boot time, or in /etc/modprobe.d/ixgbe.conf where it would read "opt= ions ixgbe allow_unsupported_sfp=3D1". Unfortunately I have no idea how to= make either of these permanent on an oVirt node. I'm running the ovirt-node-iso-3.0.1-1.0.2.vdsm.el6.iso image. It has an /= etc/modprobe.d directory where changes do not persist across reboots. It a= lso has /config/etc where I've added modprobe.d and modprobe.d/ixgbe.conf. = By adding this file to /config/files, I've been able to make it appear in = /etc/modprobe.d at boot time. This has no effect. It appears to take plac= e after the ixgbe driver has already been started. If I "rmmod ixgbe" and = "modprobe ixgbe" manually, it works fine. So the general question is, how do I make configuration changes which persi= st across reboots? Surely others have run into the same situation when try= ing to support specific devices.

[Users] Quota for VMs created from templates
by Mitja Mihelič 08 Oct '13

08 Oct '13

Hi! We are running engine version 3.3.0 on CentOS6 and we have come across a problem, possibly a bug. When a user creates a VM from a template, the template's quota is assigned to the VM. Here is the setup: - quota is set to Enforced on the data center - quota is created for template purposes (TemplateQuota) - a template is created from a sealed VM with TemplateQuota assigned to it - quota is created for a user, the user is set as its consumer - the user creates a VM from the mentioned template and leaves the quota unchanged - the created VM consumes the user's storage quota but does not consume their memory and CPU quota This way a user can create and run an arbitrary number of VMs as long they stay within their storage quota. No errors are reported in the logs. Kind regards, Mitja Mihelic -- -- Mitja Mihelič ARNES, Tehnološki park 18, p.p. 7, SI-1001 Ljubljana, Slovenia tel: +386 1 479 8877, fax: +386 1 479 88 78

[Users] A security issue in ovirt 3.2 on fedora - setup leaves a world-writable /etc/sysconfig/nfs
by Yedidyah Bar David 08 Oct '13

08 Oct '13

Hi all, The setup code of ovirt releases 3.2 and older set wrong permissions for several files, depending on options chosen during setup/upgrade. The potentially-affected files are: /etc/sysconfig/nfs /etc/sysconfig/iptables /etc/httpd/conf/httpd.conf.BACKUP* /etc/httpd/conf.d/ssl.conf.BACKUP* files under the ISO domain copied there by setup, by default under /var/lib/exports The bug does not affect systems with linux kernels older than 3.1, which included undocumented behavior that prevented it from occurring. Here is a link to the kernel patch that dropped this undocumented behavior: https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit… In practice this means that among the distributions supported by ovirt, only ovirt on Fedora is affected. ovirt 3.3 is not affected as-is. Systems upgraded from 3.2 might still have the files with wrong permissions, and should follow the actions below. How to fix an existing system? Change the permissions of existing files by running the following commands as root: chmod 600 /etc/sysconfig/nfs chmod 600 /etc/sysconfig/iptables chmod 600 /etc/httpd/conf/httpd.conf.BACKUP* chmod 600 /etc/httpd/conf.d/ssl.conf.BACKUP* find /var/lib/exports -perm /002 -type f -exec chmod 600 {} \; For the last command, replace "/var/lib/exports" with the appropriate directory, if you did not accept the default during setup and configured another directory to hold the ISO domain. A fix for this bug was pushed to gerrit: http://gerrit.ovirt.org/19557 Security implications: This bug allows local users escalate their privileges by editing /etc/sysconfig/nfs and waiting until the nfs service will be started/stopped (e.g. a reboot of the machine). -- Didi

Hello, I've seen ovirt can support plugin ... so is there any documentation about writing a plugin ? Can we write it in python ? Well because, here, we don't want to install openstack/neutron for network management ... It's too complicated and to heavy. I, your opinion wrong design choice about openvswitch implementation.
