Up to now for me a thin disk is space that is allocated on demand. But if I create VM from a template and use type "Thin" it must be a little bit different. The newly created VM will operate on the frozen template data plus some delta file that stores the changed block. Is that right? Shouldn't that be a "linked-disk"? Extra question: Why can't I move a (thin provisioned) template disk and instead have to copy it and delete it afterwards? Thanks in advance.

by Gianluca Cecchi 19 Dec '13

19 Dec '13

Hello, when editing a VM I see in console section that there is an option defined as: VirtIO Console Device Enabled By default the checkbox is not selected. I didn't find clear references to what this option enable/disable inside the guest... Thanks in advance for any clarification. Gianluca

[Users] Bridge w/o IP address?
by Blaster 19 Dec '13

19 Dec '13

I want to put multiple VMs on the same hypervisor, some will be Internet facing, some will be internal facing. I obviously don't want the hypervisor to be an attack vector, so I don't want the HV to have an IP address on the DMZ network. Is this configuration as simple as creating another another bridge like the ovirtmgmt bridge, not giving it an IP address, and adding it to the DMZ facing hosts?

Any recommended file system to use to hold VM disk images? EXT4? BTRFS(disable COW I assume?)? ZFS? XFS?

[Users] Ubuntu & Debian guest agent
by Sven Kieske 19 Dec '13

19 Dec '13

Hi, I'm currently investigating the use of the guest agent on the above mentioned operating systems (12.04.3 lts server for Ubuntu and Debian 7). The wiki pages seem outdated to me, as it states for Ubuntu: "There are binary packages available on launchpad PPA. These packages are just for demo." AFAIK there should be somewhere a package with production ready agent at least for Ubuntu(I saw this mentioned somewhere)? ATM I'm running engine 3.3.1 but plan to upgrade to 3.3.2, once RC gets released on Monday. Are there any known limitations in combining different agent/vdsm/engine versions? Can someone point me to some more accurate and up-to-date information than these? http://www.ovirt.org/Ubuntu/GuestAgent http://www.ovirt.org/Debian/GuestAgent http://www.ovirt.org/Category:Ovirt_guest_agent http://www.ovirt.org/Ovirt_guest_agent Thanks in advance -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.

[Users] oVirt run once Linux boot options
by Jakub Bittner 19 Dec '13

19 Dec '13

Hello, I am wondering howto use this feature. Is it possible to install server from this dialog? I specified kernel and initrd path as http url to our spacewalk server and to kernel parameters I added ks=http://spacewalk.server.url/ks.cfg, but it did not start. Is it possible to connect oVirt with spacewalk 2.0 (redhat satellite 5.6) to provision servers? Thank you.

[Users] Solaris 11.1 ISO panic on boot
by Blaster 19 Dec '13

19 Dec '13

I have a Solaris 11.1 system running on a nice piece of hardware that I’d like to make better use of. I would like to virtualize it under ovirt. I created an ovirt guest using the RHEL 64 bit template. I attached the Solaris 11.1 ISO and booted. As soon as the Solaris banner is displayed, poof, kernel panic. Of course every whizzes by so fast I have no chance of getting a screen shot. Has anyone been successful in boot Solaris 11.1 under ovirt? Should I have picked a different template?

Re: [Users] simple networking? [SOLVED] mostly
by Juan Pablo Lorier 19 Dec '13

Itamar, I have the same problem and already have mentioned that in previous posts. In my case, I have vlan 128 tagged assigned for ovirtmgmt so I set the host ip manually on top of a vlan interface and the, after ovirt does install the node, it fails to finish as it can't manage properly to create the bridge and pass the ip to the brand new bridge. The ovirtmgmt interface I create in engine is a bond (and originally I configure just a single interface with the ip to grant engine access), just in case this changes the scenario. Regards,
