[Users] Multi-Host Network Configuration
by Piotr Kliczewski 28 Jan '14

28 Jan '14

Hi, I played with multi host network config and used two boxes to test it. One el6 (vdsm) and f19 (engine, vdsm). During the test I noticed that vdsm on f19 haven't joined to cluster (known issue). I performed modification of vlan and MTU. Both boxes were modified but I noticed that by accident I modified ovirtmgmt network and I noticed that I lost connectivity. el6 box recovered whereas f19 haven't. I think it was because the vdsm was local to the engine. I spend sometime trying to recover network configuration. Thanks, Piotr

[Users] Update request to support "Classless IN-ADDR.ARPA delegation"
by Michelle&Judie 28 Jan '14

28 Jan '14

Hi guys, I found a problem on installing server, which has address from small ip zone, less than a class C. "engine-setup" checks FQDN resolvability in "./plugins/ovirt-engine-setup/config/hostname.py". This program requests forward & reverse query to DNS, and see if it comes back to host domain name. But it does not support RFC2317("Classless IN-ADDR.ARPA delegation") type domain, and fails on FQDN check. See following URLs for RFC2317 explanation. http://support.simpledns.com/KB/a146/how-to-sub-delegate-a-reverse-zone.aspx http://www.rfc-editor.org/rfc/rfc2317.txt I made patch to "hostname.py" to clear this problem. Please check following patch, and consider upgrading on the next release. --- hostname.py.org 2013-12-13 17:22:11.000000000 +0900 +++ hostname.py 2014-01-28 18:01:09.514791351 +0900 @@ -96,15 +96,16 @@ flags=re.VERBOSE, pattern=r""" ^ - (?P<query>\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}).in-addr.arpa. + (?P<query>[\w/.-]+) + \. \s+ \d+ \s+ IN \s+ - PTR + (?P<type>(PTR|CNAME)) \s+ - (?P<answer>[\w.-]+) + (?P<answer>[\w/.-]+) \. $ """ @@ -171,11 +172,32 @@ args=args, raiseOnError=False ) + ad=addr.split('.') + query="{3}.{2}.{1}.{0}.in-addr.arpa".format(*ad) if rc == 0: for line in stdout: found = self._DIG_REVLOOKUP_RE.search(line) - if found: - names.add(found.group('answer')) + if not found: + continue + if query != found.group('query'): + continue + answer=found.group('answer') + if found.group('type') == 'CNAME': + self.logger.debug( + '{query} CNAME to: {answer}'.format( + query=query, + answer=answer, + ) + ) + query=answer + continue + self.logger.debug( + '{query} resolves to: {answer}'.format( + query=query, + answer=answer, + ) + ) + names.add(answer) return names def _validateFQDNresolvability(self, fqdn): Upgrading to a better patch is greatly appreciated.

[Users] Setup Networks: Unexpected exception
by Frank Wall 28 Jan '14

28 Jan '14

Hi, still testing 3.4 and I'm unable to save a node's network configuration in webadmin: Error while executing action Setup Networks: Unexpected exception My configuration on the ovirt node: - manually added net2 bridge, attached to eth1 My configuration in ovirt-engine webadmin: - added new network net2 - noticed that ovirt failed to find this network on node - tried to add net2 to node with "Setup Host Networks" Error in engine.log [1]. Error in vdsm.log [2]. I think it could be related to BZ 1054195: https://bugzilla.redhat.com/show_bug.cgi?id=1054195 ([NetworkLabels] Attaching two labeled networks to a cluster result in failure of the latter) I'm not sure, because I only wanted to add *one* new network.

[Users] oVirt 3.4 - testing days report [read only disks]
by Martin Perina 28 Jan '14

28 Jan '14

Hi, I tested read only disks feature [1] and it worked fine. I used this configuration: 1) RHEL 6 VM rhel1 with shared disk mounted as RW, 2) RHEL 6 VM rhel2 with shared disk mounted as RO 3) Windows 7 VM win71 with shared disk mounted as RO rhel2 and win71 VMs sees all files on shared disk, but the disk was read only for them.

[Users] Strange UI bug: tab "VM" unusable / oVirt 3.3.1+
by Frank Wall 28 Jan '14

28 Jan '14

Hi, I'm experiencing a strange UI bug in the Amdin Portal. The "Virtual Machines" tab is unusable in serval ways: - when selecting a VM, all buttons are greyed-out, except "New VM" - you cannot power on, power off, open console or edit a VM - when selecting a VM, the VM-specific tabs do not appear on the bottom All other tabs, especially the "Hosts" tab are working as expected. Initially I suspected an incompatible browser on my side, so I tried with Firefox 25, Chrome and IE 11. No success. This UI bug hit me after upgrading from oVirt 3.3.0 to 3.3.1. And it is still reproducable in oVirt 3.3.2 BETA1. Any hint on this? Or any advice how to provide some useful debug output? I have to mention that I am able to workaround this bug: - select a VM - right click, choose "New VM", click "Cancel" - now most VM actions are no longer greyed-out - power on the VM - still the "console" button remains greyed-out Thanks - Frank

The Snapshot list of a VM remained empty in Firefox although I know that snapshots exist. The "Create Snapshot" button was still working and issued the right commands. Nevertheless the list remained empty. Opening an IE session prooved that everything was ok. The pane was populated with the list of snapshots. After restarting Firefox everything was fine again. Has anybody experienced simialr issues and if yes is there already an opn BZ for that?

The default/default data center/cluster had to be abandoned because of a split-brain that could not be healed. Can't remove old storage from database, can't get data center up due to corrupt storage, ends up a circular argument. I started over with same hosts, totally new storage in new data center. This mill/one data center/cluster was working fine with VM2 storage, then died. Ted Miller
