[Users] local iso folder not mounted
by Umarzuki Mochlis 10 Sep '12

10 Sep '12

Hi, I installed ovirt 3.1 from dre repo on centos 6 using allinone plugin from that repo it timed-out during adding local host when I logged into web management, I can see on host's tab that local_host failed to be installed and NFS ISO domain (which actually a local folder) was failed to be mounted. But I can mount it with mount.nfs manually. What did I missed here? I wanted to create a single ovirt server for testing purposes. -- Regards, Umarzuki Mochlis http://debmal.my

[Users] VNC console connection information dialog doesn't show host's FQDN
by Adam Tkáč 10 Sep '12

10 Sep '12

Hello all, oVirt web interface doesn't write host's hostname in VNC connection info dialog. It writes only IP address. Is it possible to configure this somewhere? I remember the dialog wrote FQDN but it doesn't write it now, not sure how it got broken. Currently the connection dialog looks like this: ---- Please use your VNC client to connect to this VM. Use the following parameters: IP:Port: 192.168.30.140:5902 Password: WxGYrAg7wjXF (note: this password is valid for 120 seconds) ---- However I would like to configure it to write this: ---- Please use your VNC client to connect to this VM. Use the following parameters: IP:Port: host.example.com:5902 Password: WxGYrAg7wjXF (note: this password is valid for 120 seconds) ---- Is it possible to do it somehow? Thank you in advance. Regards, Adam

[Users] Cannot add another host to "all-in-one" datacenter
by Adam Tkáč 10 Sep '12

10 Sep '12

Hello all, I installed an oVirt datacenter via "all-in-one" plugin, which means everything currently runs on one machine. I would like to add another host to this datacenter, it has it's own storage for virtual machine images, but oVirt refuses to add it with error "Cannot add more than one Host to "Local Storage" Data Center". Is it possible to configure this somewhere and add the host to the local_datacenter? Thank you in advance for response. Regards, Adam

Re: [Users] Can't add NFS domain
by Changsen Xu 10 Sep '12

Damiano, Thanks a lot for your answer. I just got vdsm compiled and installed on fresh FC17 (installed with live cd), used your 3.4.9 FC16 kernel. Yes, now, engine can add it as host, great. But engine still can't add NFS domain. Any idea what is happening?

[Users] [oVirt 3.1] Export VM
by Andres Gonzalez 10 Sep '12

10 Sep '12

Hello, I have a VM that has a 30 GB thin provisioned hard disk, but when I make an export from the GUI the process allocates 30 GB instead of the 6 GB that the disk is using now. This could be something that I have wrong or a bug ? I have installed oVirt 3.1 under CentOS 6.3 (dre repo). Also, is there any way to upgrade qemu to have the possibility of make live snapshots and exports ?! Thanks. Regards.- -- AGD

Hi, Forgive me if this is a dump question. What is the difference between ovirt and openstack projects? Are both of these projects perform the same job creating a cloud? Thanks, Neo

[Users] oVirt-engine Migration Docs
by Neil 07 Sep '12

07 Sep '12

Hi guys, I've read the following regarding upgrading from 3.0 to 3.1... "Due to the nature of this upgrade, we DO NOT recommend it, users are advised to do a 3.1 clean installation, and to import all VM's and template into the new installation." I'm running a live ovirt-engine(very early 3.1 release with no upgrade path) system with 3 VM's and I'd like to do the recommended -- "clean installation and import all VM's and template", but I'd like to know if there are any detailed guides on how to do this? I also have an unused server that I can use as a spare host that I can add into my clean engine install to get the VDSM onto the latest version as well, but how do you go about exporting and importing the VM's and the template? I am working on a live system and downtime needs to be limited, not sure if this is the correct procedure? Prepare old engine: 1.) Create a export storage domain 2.) Suspend each VM and export (presume suspending is enough and they don't need to be shutdown?) 3.) Detach export storage domain Prepare new engine machine: 1.) Install new ovirt-engine 2.) "Restore previous keystore and preserve .sh scripts" presume this is how the configs and DB are restored? 3.) Log into ovirt as admin and add only the spare host (to ensure that VDSM 4.10 is used, because I'm currently using VDSM 4.9) 4.) Attach export storage domain 5.) Import VM's all running on new "spare" host Upgrade old VDSM hosts: 1.) Remove VDSM 4.9 on old hosts(2 of them)? 2.) Add/install the new hosts from inside webadmin to get the old hosts up to VDSM 4.10? I'll gladly document the steps in detail if there is no detailed guide already for this. Thanks, any assistance is greatly appreciated. Regards. Neil Wilson.

[Users] Problem with creating a glusterfs volume
by Dominic Kaiser 06 Sep '12

06 Sep '12

So I have a problem creating glusterfs volumes. Here is the install: 1. Ovirt 3.1 2. 4 Nodes are Fedora 17 with kernel 3.3.4 - 5.fc17.x86_64 3. 4 nodes peer joined and running 4. 4 nodes added as hosts to ovirt 5. created a directory on each node this path /data 6. chmod 36.36 -R /data all nodes 7. went back to ovirt and created a distributed/replicated volume and added the 4 nodes with brick path of /data I received this error: Creation of Gluster Volume maingfs1 failed. I went and looked at the vdsm logs on the nodes and the ovirt server which did not say much. Where else should I look? Also this error is vague what does it mean? -- Dominic Kaiser Greater Boston Vineyard Director of Operations cell: 617-230-1412 fax: 617-252-0238 email: dominic(a)bostonvineyard.org
