Hi, I'm seeing the errors mentioned in the subject line with my new oVirt installation. I've tried to remove the metadata's checksum line and re-activate, to no avail. For background, please see: http://pastebin.com/raw.php?i=R2SH5ah8 I'm unable to detach and activate my ISO domain. Please advise. Thanks, Joshua -- Joshua Dotson Founder, Wrale Ltd

[Users] Planned outage :: resources.ovirt.org/lists.ovirt.org :: 2013-01-21 01:00 UTC

This is an OpenPGP/MIME signed message (RFC 4880 and 3156) ------enig2QPOTWAJSDKQFRARSDTUF Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable There will be an outage of www.ovirt.org for approximately 45 minutes. The outage will occur at 2013-01-21 01:00 UTC. To view in your local time= : date -d '2013-01-21 01:00 UTC' I may start part of the outage 15 minutes before that. If you anticipate needing services until the outage window, reply back to me with details ASAP. =3D=3D Details =3D=3D We need to resize the Linode instance to get another 15 GB for storage until we can move services off the Linode permanently, as planned. This resizing should give us some breathing room. The account resize is estimated to take 30 minutes, during which time the Linode VM will be offline. After that, there will be a few minutes for reboot and restart of services, including the manual starting of the IRC bot 'ovirtbot'. The time window chosen coincides with the lowest CPU usage typically seen on any given day - 01:00 UTC tends to be very quiet for about an hour. Hopefully no one will even notice the downtime. If you have any services, such as Jenkins or Gerrit backup, that may go off during that window, you may want to retime it or be prepared for an error. =3D=3D Affected services =3D=3D * resources.ovirt.org ** meeting logs ** packages * lists.ovirt.org (MailMan) * ovirtbot * Gerrit backup (anacron may pick this up) * Other cronjobs (anacron may pick this up) =3D=3D Not-affected services =3D=3D * www.ovirt.org (MediaWiki) * jenkins.ovirt.org * gerrit.ovirt.org * alterway{01,02}.ovirt.org --=20 Karsten 'quaid' Wade, Sr. Analyst - Community Growth http://TheOpenSourceWay.org .^\ http://community.redhat.com @quaid (identi.ca/twitter/IRC) \v' gpg: AD0E0C41 ------enig2QPOTWAJSDKQFRARSDTUF Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.13 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iD8DBQFQ/C5s2ZIOBq0ODEERAielAKCYj7E23olhFjrftzhIdMey/n4k9QCdG4MR ILrAtGG53Wnn545S12rdacI= =C+px -----END PGP SIGNATURE----- ------enig2QPOTWAJSDKQFRARSDTUF--

[Users] Attaching an existing KVM installation to oVirt
by Eric_E_Smith＠DELL.com 20 Jan '13

Hello - I'm new to the list and thought I would send my first email. Is there a way to attach an existing KVM installation (Non Fedora - non node based installation of say, CentOS or Ubuntu) to oVirt? Thanks in advance, Eric

[Users] Storage domain weirdness (or design)
by Alex Leonhardt 20 Jan '13

20 Jan '13

Hi, I see a strange behaviour - Setup: 1 ovirtmgmt / ovirt-engine hsot 2 ovirt nodes / HVs 2 storage domains in same cluster & DC HV1 => storage domain 1 (master) HV2 => storage domain 2 Issue: When I create a host with say ~40GB disk to be on HV2/storage_domain_2, it does that via HV1 ? Why is that ? I realize a storage domain is "attached to the cluster/dc", however, when creating the VM I explicitly seleted to only run on HV2, so why would it still create the disk via HV1 ? The mgmt network (for now) is only just that, a mgmt network, not meant to create 40 GB disks (dd from /dev/null) over NFS .. it's currently only a 100mbit switch Question: How, if at all, can I make Ovirt create the Disk from the host where it's meant to run on ? Thanks, Alex -- | RHCE | Senior Systems Engineer | www.vcore.co | www.vsearchcloud.com |

[Users] mark VM to start on boot
by Jim Kinney 20 Jan '13

20 Jan '13

How do I mark a VM to startup if a node fails? 2 hosts in cluster, windows domain controller on one host, backup on second host. Both are marked high priority. "Bad Things" happen and both hosts get rebooted. I want those domain controllers to automatically restart. I'm assuming the failure of the hosts did not knock down the manager. (I have them on separate floors, power, etc). -- -- James P. Kinney III * *Every time you stop a school, you will have to build a jail. What you gain at one end you lose at the other.

Re: [Users] Thin provisioning extending while "Make template" still a bug?
by Maor Lipchuk 19 Jan '13

Hi Adrian, Sorry for the late respond. Please see inline comments, and feel free if there are any more questions, or other issues which you want us to address to. p.s. Since some of the responds were in different threads, I gathered all of them to this email. > 3) About the attached logs the virtual machine made from template was > finally made at: > 2012/12/22 17:21 > Logs are from 16:17 to 17:21 aproximately and I might reuse them to > ask why it takes so long to make the virtual machine while checking > the storage image at /home/storage (its size) it would seem that the > copy has finished. > I think that the "Make vm from template" task started about 30 > minutes or 40 minutes before it being finished. Well, that's the > average time it takes for me. Since you are creating a server the default behaviour is to clone your disks, which means engine calls copyImage to the SPM. >From what I saw in the logs your template have two disks, which one of them is 1920 GB, this is why it took 30 minutes to copy it. If you want your copy to be faster, you can change the default in the resource allocation tab to use thin instead of clone when you add a new server. although, take in notice that when you will use thin provisioning, the server will be based on the template and you will not be able to remove the template until the VM will be removed.

If you can still reproduce this scenario when you create a template with wrong provisioning, please attach the logs of it.

[Users] hierarchy map of ovirt environment
by Jiri Belka 19 Jan '13

19 Jan '13

Hello, in vSphere you can have 'views' like Storage views, Network views... Example: http://i.techrepublic.com.com/blogs/sept-2010-virtualizationtips-tip4-figc.… This is very useful, typical scenario is when delivery manager asks sysadmins about potential impact on VMs when a scheduled update of a switch/storage box goes wrong. It's easy in vSphere, just check 'views' and you will see it. Something like this possible in oVirt? It would be nice to have it as 'map', also as 'result' of searching, something like... vms: network.name = foo and network.risk = down jbelka

[Users] Settings lost after node reboot
by Nicolas Ecarnot 18 Jan '13

18 Jan '13

Hi, Migration failed due to a lack of an iptables rules about tls > # libvirt tls > -A INPUT -p tcp --dport 16514 -j ACCEPT I added it in /etc/sysconfig/iptables and migration worked. After a reboot, this rule is lost, as well as some setting I added in /etc. I see the the nodes have very specific mouting strategies, and/or read only architecture. I'm not sure I want to become an expert about why and how it's done, but I'd be glad if someone just tells me where I have to write my settings in order them to resist node reboot? Thank you. -- Nicolas Ecarnot
