Re: [ovirt-users] oVirt + opennode or oVirt+proxmox
by Juan Pablo Lorier 20 Jul '14

Hi Robson, I don't know openode, but I can tell you that I can't think of a way of using proxmox along ovirt. Both are virtualization platforms based on KVM (so you can run vms from one platafrom into the other without any conversion, just export-improt,copy or whatever you need to go from one to the other). They have both their upsides and downsides, basically IMHO, I like proxmox decentralized way of managing the platform, but I love more the great community around ovirt and it's fast evolution. One thing is certain, your virtualization host can't be both, ovirts and proxmox virtualization hosts. Regards,

Ceph support
by Johan Kooijman 18 Jul '14

18 Jul '14

Hi all, Does somebody have *any* idea on when oVirt will start to support Ceph through libvirtd? I could mount an RBD volume onto a server and then expert it as NFS, but that kills my I/O throughput quite severely (write IOPS go down by 84%). Ceph is the way to go for storage needs if you ask me, but I'd rather not move away from ovirt because there's no support. -- Met vriendelijke groeten / With kind regards, Johan Kooijman

Relationship bw storage domain uuid/images/children and VM's
by Steve Dainard 18 Jul '14

18 Jul '14

Hello, I'd like to get an understanding of the relationship between VM's using a storage domain, and the child directories listed under .../<storage domain name>/<storage domain uuid>/images/. Running through some backup scenarios I'm noticing a significant difference between the number of provisioned VM's using a storage domain (21) + templates (6) versus the number of child directories under images/ (107). Running RHEV 3.4 trial. Thanks, Steve

[ANN] oVirt 3.4.3 Release is now available
by Sandro Bonazzola 18 Jul '14

18 Jul '14

The oVirt development team is pleased to announce the general availability of oVirt 3.4.3 as of Jul 18th 2014. This release solidifies oVirt as a leading KVM management application and open source alternative to VMware vSphere. oVirt is available now for Fedora 19 and Red Hat Enterprise Linux 6.5 (or similar). This release of oVirt includes numerous bug fixes. See the release notes [1] for a list of the new features and bugs fixed. The existing repository ovirt-3.4 has been updated for delivering this release without the need of enabling any other repository, however since we introduced package signing you need an additional step in order to get the public keys installed on your system if you're upgrading from an older release. Please refer to release notes [1] for Installation / Upgrade instructions. Please note that mirrors will need a couple of days before being synchronized. If you want to be sure to use latest rpms and don't want to wait for the mirrors, you can edit /etc/yum.repos.d/ovirt-3.4.repo commenting the mirror line and removing the comment on baseurl line. A new oVirt Live ISO will be available too[2].

oVirt 3.4.3 GA postponed due to blocker
by Sandro Bonazzola 17 Jul '14

17 Jul '14

Hi, recent python upgrade in Fedora 19 broke vdsmd service. While we wait for an updated python-cpopen package to be built, we're postponing oVirt 3.4.3 GA. The package should be built for tomorrow and will be hosted on ovirt repo until it will be available on Fedora repositories. We'll release 3.4.3 after basic sanity testing with the new package.

small cluster
by urthmover 17 Jul '14

17 Jul '14

I have 10 mac minis at my disposal. (Currently, I’m booting each device using a centos6.5 usbstick leaving the 2 disks free for use) GOAL: To build a cluster of 10 servers running postgres-xc EQUIPMENT: 10 mac mini: i7-3720QM(a)2.60GHz/16G RAM/1x1gbit NIC/2x1TB SSDs (zfs mirrored) REQUEST: Please run the software application postgres-xc (a multi-master version of postgres). I'm told by the DBA that disk IO is the most important factor for the tasks that he’ll be running. The DBA wants 10 servers each with a 50G OS partition and a 800GB /data. THOUGHTS: I have a few ideas for how to accomplish but I'm unsure which is the best balance between disk IO and overall IT management of the environment. QUESTIONS FOR THE LIST: Should I present each of the 10 mac mini’s mirrored disks to glusterfs thus creating a large 10TB storage area. Then connect the storage area to ovirt-engine creating on 10TB storage domain, and use it as the storage domain for 10 large 800GB disks (a /data for each guest) ? Should I present each mac mini’s mirrored pair as an nfs share to ovirt-engine? This would create 10 1TB storage domains. Then create 10 large 800GB /data partitions (a /data for each guest). Should I NOT use ovirt and just run each mac mini as a mirrored pair of disks and a sandalone server? LASTLY: I’m open to any other thoughts or ideas for how to best accomplish this task. Thanks in advance, -- urthmover

[QE] Hardening Guide
by Sandro Bonazzola 17 Jul '14

17 Jul '14

Hi, while I was working on Bug 1097022 - ovirt-engine-setup: weak default passwords for PostgreSQL database users I was wondering where to write hardening tips described in comment #18. It looks like we don't have any page on oVirt wiki about hardening. Anyone interested in contributing to such page? I guess it can be created as http://www.ovirt.org/OVirt_Hardening_Guide Thoughts? -- Sandro Bonazzola Better technology. Faster innovation. Powered by community collaboration.

Missing Storage domain
