[Users] Documentation: Storage Domain conversion from Data Domain to Export Domain
by Michael Ayers 29 Nov '13

29 Nov '13

This is a multipart message in MIME format. ------=_NextPart_000_018F_01CDB69A.3C5318B0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Hey All, I ran into this issue myself where I needed to convert a data domain to an export domain in order to recover virtual guests from a corrupted ovirt/rhevm instance into a new ovirt/rhevm instance. This wasn't documented anywhere that I saw but with the help of Itamar Heim and an well timed email to the list from Igor Lvovsky last night I was able to do this and wanted to send to the list a documented procedure for how to modify the metadata of the data domain prior to import as an export domain. This procedure works for both RHEV-M and Ovirt. Let me know if you have any questions.

[Users] Trusted Pools and CentOS 6 packages
by Gianluca Cecchi 15 Nov '13

15 Nov '13

Hello, based on http://www.ovirt.org/Trusted_compute_pools_deployment#Provision_White_List_… The commands of kind: bash_oat_cert .. bash oat_oem ... are to be run on hypervisor host side, correct? Where can I find these packages for CentOS 6? Thanks in advance Gianluca PS: I took the time to correct a typo in client section where it said "Yum Install oat server package from fedora19 repository" instead of "Yum Install oat client package from fedora19 repository"

Re: [Users] so, what do you want next in oVirt?
by Juan Pablo Lorier 11 Nov '13

Hi, I think that one of the best things from Proxmox is the ability to connect to any of the hosts via web and been able to admin the hole infrastructure from there. This avoids the single point of failure that today engine represents in ovirt plataform. I agree with Jakub that been able to mix Intel and AMD hosts would be great so we can use the hole of the servers into a DC and engine may migrate VM to the same kind of processors if available but if not, migrate to any available host and alert about the performance degradation. I'm still a rookie to ovirt so at this time I don't know all the features to make further coments. I think you have a great product and the best of it is the speed it's improving. Regards,

[Users] so, what do you want next in oVirt?
by Itamar Heim 26 Oct '13

26 Oct '13

earlier in the year we did a survey for feature requests / improvements / etc. since a lot of things were added, and priorities usually change, I'd like to ask again for "what do you need the most from oVirt / what are your pain points" next? below[1] I've listed my understanding of what already went in from previous survey requests (to various degrees of coverage). Thanks, Itamar [1] from the top 12 V Allow disk resize V Integrate Nagios/Zabbix monitoring - via a ui plugin V Highly Available engine - via hosted engine[2] V Open vSwitch integration - via neutron integration X Allow cloning VMs without template ? Enable hypervisor upgrade/updates through engine[3] V Allow engine on an oVirt hosted VM - via hosted engine[2] V Enable guest configuration (root password, SSH keys, network) via guest agent in engine - via cloud-init X Integrate v2v into engine ? Bond/extend ovirtmgmt with a second network for HA/increased bandwidth[4] X Integrate scheduling of snapshots and VM export for backups in engine[5] V Spice – support Google Chrome - via mime based launch Other items mentioned in previous survey which should be covered by now: - Fix timeout when adding local host during all-in-one configuration - Fix engine set-up when SELinux is disabled - Provide packages for el6 (CentOS, Red Hat Enterprise Linux) - Allow multiple VMs to be deployed from the same template at the same time - ISO domains on local/GlusterS - Show IP addresses in Virtual Machines->Network Interfaces - OpenStack Quantum support (now called Neutron) - noVNC support - Support spice.html5 and websocket proxy - Add other guest OSes to list - Port oVirt guest agent to Ubuntu[6] - SLA - Allow resource time-sharing - Spice - Mac client (via mime based launch) - Spice - port XPI plug-in to Windows (not sure this will happen, but mime based launch allows using firefox now) - Spice - client for Ubuntu/Debian (should be covered via mime based launch) [2] hosted engine is in active development, but not released yet. [3] host update is supported, but not for general yum update. [4] a lot of improvements were done in this space, but i'm not sure if they cover this exact use case [5] backup api is now being pushed to master, and orchestration of backups should probably happen via 3rd part backup vendors? [6] I'm not sure packaging exists yet, but ubuntu is covered for the basic functionality of the guest agent.
