[Users] Confused about Gluster usage
by Martijn Grendelman 11 Mar '14

11 Mar '14

Hi, I have been running oVirt 3.3.3 with a single node in a NFS type data center. Now, I would like to set up a second node. Both nodes have plenty of storage, but they're only connected to each other over 1 Gbit. I'm running nodes on CentOS 6.5. What I would like to accomplish is: * use a Gluster-backed DATA domain on my existing NFS datacenter * load balancing by even spread of VMs over the two nodes * leveraging the speed of local storage, so running a VM over NFS to the other node is undesireable So I was thinking I want the storage to be replicated, so that I can take a node down for maintenance without having to migrate all the storage to another node. I was thinking: GlusterFS. But I am confused on how to set it up. I understand I cannot use the libgfapi native integration due to dependency problems on CentOS. I have set up a replicated Gluster volume manually. How can I use my two nodes with this Gluster volume? What are the necessary steps? I did try a couple of things; most notably I was able to create a 2nd data center with POSIX storage, and mount the Gluster volume there, but that doesn't work for the first node. Alternatively, it would also be fine to migrate all existing VMs to the POSIX datacenter and then move the existing node from the old NFS data center to the new POSIX data center. Is that possible without exporting/importing all the VMs? Cheers, Martijn.

[Users] ovf image for hosted engine
by Jason Brooks 11 Mar '14

11 Mar '14

Hey all, The hosted engine may be installed from pxe, cdrom or disk. The disk format must be an OVF image, right? Any suggestions on how to create an ovf image? Poking around, I see mentions of tools to convert from ovf, but not to ovf, at least not within the KVM/libvirt world. I know that this format is used within oVirt, but I don't understand how to go from the *.ovf file in the export domain + the disk image file or files to a single disk image. Do these have to be zipped together? Is there some utility for that, or guidance on how it comes together? My cdrom and pxe hosted engine installs have been spotty -- some crashes, some unresponsiveness from pxe and from the cd install -- so I'd like to know how to take the disk route... Thanks, Jason

Re: [Users] oVirt in PAT - NAT environment

Hi René, I don´t have a second NIC, only a public on eth0. So, if I understood correctly, Neutron is not part of oVirt, but needs to be installed a part. I need to use the All-in-one version of oVirt, so I need to install Neutron on this same host? Any additional advice? ----- Ursprüngliche Mail ----- Von: "René Koch" <rkoch(a)linuxland.at> An: "relaxibus" <relaxibus(a)akfree.it> CC: "Assaf Muller" <amuller(a)redhat.com>, users(a)ovirt.org Gesendet: Montag, 10.

[Users] ovirt-engine certs
by Thomas Scofield 11 Mar '14

How can I regenerate the ovirt engine CA certs and corresponding vdsm certs? I have an ovirt setup that I'm upgrading from 3.2.0 (from the dre repos) to 3.2.3 and I am getting the certificate errors listed below after the upgrade. I have done this same upgrade on an number of other ovirt-engines with no issue. The setup had originally been installed with ovirt 3.1 so it possible that some of the certificate configurations from 3.1 are still present on this ovirt-engine and it is contributing to the problem. For example, I noticed that the /etc/pki/ovirt-engine/cacert.conf file on this troublesome upgrade has "default_bits = rsa:1024", but the systems that upgraded successfully have "default_bits = rsa:2048". The same is true for the cert.conf file.

Hello folks, I know, this is a topic where you have spend a lots of words, but, after installing oVirt 3.3 and 3.4 on CentOS and let goign google search engine to become hot, I don´t found any solution for my environment. My environment: - dedicated server at "server4you.net" with CentOS 6 - Main IP (public) 82.25.xx.yy - Addon IP (public) 62.75.xx.yy What I will do: - create VMs on a private network 192.x.y.z - talk to the internet from the VMs (NAT) - reach the VMs from the internet (PAT) - reach the VMs via SSH from the host server I found some "workarounds", but no one was easy to implement or the infos was not cobering all the aspects. I have seen the possibility to use a "hook", but no user guide and step by step instruction found. Looking forward to get a working solution :-) Cheers, -Jarno
