[Users] Gluster Compatibility
by Barry French 11 Feb '12

11 Feb '12

Hi, Is oVirt able to use glusterfs to access gluster shares. I know gluster can export NFS shares but using the glusterfs client provides redundancy over all gluster brick ip's, whereas standard NFS does not. Thanks.

[Users] Possible to migrate from an existing KVM/Libvirt VM (installed in an LVM) ?
by Morgan Cox 10 Feb '12

10 Feb '12

Hi Can an existing KVM/Libvirt VM (installed in an LVM) ever be migrated to an Ovirt node (offline migration is ok.) ? Also - when Ovirt is released - what OS is the going to be used for .iso for the node - i.e it is going to be based on Fedora or RHEL (centos) ? (i know you can get packages for other os's) Regards

[Users] [USERS] 2 more questions regarding upgrade of the nodes
by Morgan Cox 10 Feb '12

10 Feb '12

I got responses in IRC to my questions. A very nice person - Mburns basically answered all my questions - I had asked about SWRAID for the nodes too As always i'm amazed how easy it is to get answers in the opensource world Many thanks to everybody involved ! Regards 12:36] <mburns> morgan: support life: it's an open project so support is just community support [12:36] <mburns> i haven't heard anything around how we're going to handle OS upgrades at this point [12:37] <mburns> but i would think that each ovirt release will be on the current versions of the different distros [12:37] <mburns> morgan: regarding nodes, if you're using ovirt-node, then it's fedora only currently [12:38] <mburns> there is work being done to be able to create clients/slaves on different distros, but not as part of the node project [12:38] <mburns> though we'd love for people who know those distros to help out creating variants of the node for each [12:39] <-- ydary has left this server (Quit: Leaving.). [12:39] <mburns> morgan: upgrading the node: the way the node is designed, upgrades are fairly easy and non-destructive [12:40] <mburns> the base image is dropped in and the configuration and shared data aren't touched [12:40] <mburns> morgan: no support for swraid in the node at this time [12:41] <mburns> morgan: i don't think it's really needed either [12:42] <mburns> there is minimal configuration to be made on the node, so re-installation in the case of a lost disk is pretty simple [12:42] <mburns> the bigger deal is the storage for your datacenters [12:42] <mburns> and if you're using nfs/iscsi/fc, you definitely want raid of some sort there

[Users] Reverse DNS really necessary?
by Floris Bos / Maxnet 09 Feb '12

09 Feb '12

Hi, oVirt's setup procedure seems to insist reverse DNS records are present. When running engine-setup interactively, you are able to override this, but with automated installations it flat outs refuses to install: == [root@ovirt ~]# engine-setup --answer-file=answers Welcome to oVirt Engine setup utility The IP 192.168.88.102 does not hold a PTR record for the FQDN: ovirt.maxnet.eu Failed handling answer file: Error reading parameter HOST_FQDN from answer file == Kinda annoying requirment, when you only want to create a quick test setup. Was wondering where it is actually using reverse DNS for? -- Yours sincerely, Floris Bos

Is there a method to pre-generate a set of certificates/configuration files for a node? It is not that hard to let the boot server serve the node-specific configuration files as a cpio (initramfs) archive, based on the MAC-address of the node. The kernel supports having more than one initramfs file, and simply combines the files from both archives. -- Yours sincerely, Floris Bos

(the others on ovirt were easy to find with google) Thanks, Joost
