[Users] Snapshot delele/merge broken. Was: Live storage migration snapshot removal (fails)
by Sander Grendelman 14 Nov '13

14 Nov '13

Snapshot deletion on preallocated FC domain disks is broken in ovirt-stable/3.3 Both online and offline snapshot deletion leads to an error and the snapshot state is changed to "BROKEN". When I apply the patch at http://gerrit.ovirt.org/#/c/19983/ from https://bugzilla.redhat.com/show_bug.cgi?id=1015071 snapshot deletion works again. Can/will this patch be backported to ovirt-stable?

[Users] Custom settings for Kernel Same-page Merging (KSM)?
by Frank Wall 14 Nov '13

14 Nov '13

Hi, recently I've noticed that ksmd is using quite a lot CPU on my oVirt node. While I have plenty RAM, my CPU is way slow. Thus ksmd is eating up the most limited ressource here. Is it supported to use custom settings for ksmd? I've noticed that it is handled by MoM: /etc/vdsm/mom.d/03-ksm.policy. May I just change some settings here, or is there a tuning parameter in oVirt engine? Couldn't find a matching one with engine-config. I'd like to use a higher value for sleep_millisecs to reduce CPU usage (with the possible side effect of higher RAM usage). Thanks - Frank

[Users] Installing Windows VMs
by Bob Doolittle 14 Nov '13

In the QuickStart Guide, it implies that you should find a virtual floppy image for virtio-win in the ISO_DOMAIN. Or at least I can find no information on where to find/populate that image before the Guide shows its use. However, in my default 3.3 installation, there was nothing pre-populated in my ISO_DOMAIN. Should there have been? Regards, Bob

Re: [Users] Default route on hosts
by Assaf Muller 14 Nov '13

Can users outside of the hosts' networks reach the VMs in the hosts? If you use netstat -rn it is expected that the gateway will be 0.0.0.0, as ifcfg-ovirtmgmt has DEFROUTE=yes and ifcfg-public has DEFROUTE=no, then ovirtmgmt's 'gateway' (0.0.0.0) will be determined as the host's default gateway. However with the new multiple gateways feature we configure source routing to make sure that traffic that comes (from the outside) in the public network's device will return the way it came in. You can use 'ip rule' to see the rules VDSM configures. It creates two rules and a routing table per device. You can use 'ip route show table %s' on each table, where the IDs can be obtained by 'ip rule'. ----- Original Message ----- From: "Chris Geddings" <chris.geddings(a)duke.edu> To: "Assaf Muller" <amuller(a)redhat.com> Sent: Tuesday, November 12, 2013 2:26:40 PM Subject: Re: [Users] Default route on hosts On Nov 12, 2013, at 3:32 AM, Assaf Muller <amuller(a)redhat.com> wrote: > oVirt 3.3 introduced a feature called multiple gateways which may assist you.

Now, my management network has a gateway of 0.0.0.0, as it is a completely simple network, so that may be part of the problem. I'm not sure the impact of a 0.0.0.0 as a gateway. I'm not sure how to poke at this further to figure out where the breakage is. Routing looks like it has gotten a little more complex, and I'm still operating with 'netstat -rn' and 'route add foo' type commands. --Chris

[Users] Bug: adding LocalStorage Data Centers
by Sven Kieske 14 Nov '13

14 Nov '13

Hi, affected version: oVirt 3.3 (ManagementNode) how to reproduce: setup 2 data centers with local storage, add data master storage domains to these 2 data centers add another data center with local storage, try to add another master storage domain. expected result: the data domain gets created just like the 2 before actual result: ovirt management complains that the data domain already exists, which is not true. This behaviour was introduced with version 3.3, we didn't see this in version 3.2 This is regardless of node versions. I would at first like to know if anybody can reproduce this? If this is the case I would create a bugzilla entry. Regards Sven

[Users] Failed to configure management network on the host
by Rob Abshear 14 Nov '13

14 Nov '13

I am running oVirt Engine Version: 3.4.0-0.2.master.20131107144332.git214186b.fc18. I am having an issue adding new hosts. I do a fresh install of fc18 on the host and then try to add it into my cluster. The controller installs all packages and it looks like it's all good, but at the end I get the message "Failed to configure management network on the host" and the host goes into non operational state. I can remove the host and add it into a second oVirt environment that I am running. This other environment is runningoVirt Engine Version: 3.2.3-1.fc18. Once I add it into that other environment, I can then remove it and successfully add it into my 3.4 environment. -- *NADA Convention & Expo*: January 24-27, 2014 - New Orleans, LA - Booth 5001 <http://www.bbb.org/south-east-florida/business-reviews/advertising-agencies…><http://www.bbb.org/south-east-florida/business-reviews/advertising-agencies…>

[Users] oVirt 3.4 planning
by Itamar Heim 13 Nov '13

13 Nov '13

To try and improve 3.4 planning over the wiki approach in 3.3, I've placed the items i collected on users list last time into a google doc[1] now, the main thing each item needs is a requirements owner, devel owner and a testing owner (well, devel owner is really needed to make it happen, but all are important). then we need an oVirt BZ for each, and for some a feature page. I also added columns indicating if the item will require an API design review and a GUI design review. this list is just the start of course for items from it to get ownership. i expect more items will be added as well, as long as they have owners, etc. the doc is public read-only, please request read-write access to be able to edit it. feel free to ask questions, etc. Thanks, Itamar [1] http://bit.ly/17qBn6F

If it works with Nagios, it works with Icinga. Cheers, Martijn.
