Upgrade from 3.5rc to 3.5 final question
by Gianluca Cecchi 29 Oct '14

29 Oct '14

I see this in release notes for 3.5: " If you're using pre-release repo you'll need to re-enable pre release repository: [ovirt-3.5-pre] name=Latest oVirt 3.5 Pre Release #baseurl=http://resources.ovirt.org/pub/ovirt-3.5-pre/rpm/fc$releasever/ mirrorlist= http://resources.ovirt.org/pub/yum-repo/mirrorlist-ovirt-3.5-pre-fc$release… enabled=1 skip_if_unavailable=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-ovirt-3.5 and to run: # yum update "ovirt-engine-setup*" # engine-setup " but this leaves me some doubts... I currently have RC3 (or 4, I don't remember exactly). But if I walk through the pre-repo mirror, it seems to me that for example I will get ovirt-engine-backend-3.5.0.1-0.0.master.20141009085636.el6.noarch.rpm while going through 3.5 repo I will get ovirt-engine-backend-3.5.0.1-1.el6.noarch.rpm Are they indeed the same? Can you confirm that if I have a RC release I still have to use -pre repo to update to official 3.5.0? Thanks, Gianluca

migrate from stand alone on FC19 to hosted OK to use CentOS 7?
by Alastair Neil 29 Oct '14

29 Oct '14

I am trying to migrate my old ovirt install which started out at 3.3 standalone engine on FC19 to a hosted engine. I want to use CentOS , however, the postgresql version on 6.5 is old (8.4.20) and I am unable to get a clean restore. The version on FC 19 is 9.2.8, it looks like EL 7 has 9.2.7 (I am hoping the difference in the minor rev will not bite me). I was wondering if there are any issues using EL 7 to host the engine? I know I had seen some reports of issues with 3.5 on EL7 as hosts but was not sure if the engine had any gotchas. Thanks, Alastair

Opened BZ for small mem leak
by Daniel Helgenberger 28 Oct '14

28 Oct '14

Hello Sven and Dan, just FYI I opened a BZ [1] for the small mem leak of VDSM, 300KiB since Sven reported the same thing and it is there (and still is) since a long time now. With some help of us it might be pinpointed; the growth is quite linear. [2] Also, I think the issue might be neglectable in many / most production environments.

Re: [ovirt-users] CoreOS can not install on Ovirt
by Brian Harrington 28 Oct '14

Punit, Former Red Hatter and current "coreo" here. First which image are you trying to load? Your best bet will be to use the QEMU image. Also take a look at the console and see what the boot: line being supplied is. --Brian 'redbeard' Harrington > Hi, > > I try to install the CoreOS (https://coreos.com/) as guest VM under ovirt > 3.5 by ISO...but if i choose this CoreOS iso.... > > [image: Inline image 1] > > But if i choose Centos iso...it start the installation without any problem > ....i already checked the ISO of CoreOS is perfectly fine...i can install > it with physical machine...but stuck in the OVirt... > > Thanks, > Punit

MacPoolRanges not working as expected
by Xavier Naveira 28 Oct '14

28 Oct '14

Hi everyone, First of all I'd like to say that we have been using oVirt successfully for more than a year, creating an automated deploy system with help of foreman and puppet. That being said, we're currently facing the first serious problem and we'd appreciate some help. Everything was working fine until we exhausted the default MacPoolRanges. After looking for a solution to the error message we found this document: http://www.ovirt.org/Engine_config_examples#MacPoolRanges Following the instructions on it we executed the following commands: First we found out what our current pool was: # engine-config -g MacPoolRanges MacPoolRanges: 00:1a:4a:24:26:00-00:1a:4a:24:26:ff version: general So we proceeded to expand it: # engine-config -s "MacPoolRanges=00:1a:4a:24:26:00-00:1a:4a:24:27:ff" # service ovirt-engine restart After this we were able to create new machines but none of them seemed to have network. After some unsuccessful troubleshooting we restored the original pool and instead added a new one: # engine-config -s "MacPoolRanges=00:1a:4a:24:26:00-00:1a:4a:24:26:ff" # service ovirt-engine restart # engine-config -s "MacPoolRanges=00:1a:4a:24:26:00-00:1a:4a:24:26:ff,00:1a:4a:24:27:00-00:1a:4a:24:27:ff" # service ovirt-engine restart After doing this and test to create a new host everything seemed to work fine. The problem is that after the successful creation of some hosts the original problem where the new hosts didn't seem to have network, reappeared. Trying to narrow down the problem what we've find out so far is: This oVirt environment kickstarts hosts via PXE, when trying to PXE boot a new host, the DHCP process fails (timeout). Tracing the network packets, we are able to see that the virtual host sends the dhcp request, the dhcp server receives it and acknowledges it and it sends the dhcp offer back. The dhcp offer reaches the hypervisor to the vnetxx network interface BUT it doesn't go further and it doesn't reach the virtual host. This behavior is consistent through different hypervisors and vlans, including the ones that have been used/created before the problems appeared. The only pattern that we've been able to identify so far is through issuing the command "brctl showmacs <bridge_name>" This command list the mac addresses for the interfaces connected to the bridge. In the cases where everything works fine the output looks like this: port no mac addr is local? ageing timer 2 00:1a:4a:24:27:e0 no 0.01 2 fe:1a:4a:24:27:e0 yes 0.00 The virtual host MAC address begins with "00" and it has a corresponding address beginning with "fe" which is assigned to the "vnetxx" interface in the hypervisor. In the cases where the virtual host doesn't get the dhcp answers the output of "brctl showmacs <bridge_name>" is: port no mac addr is local? ageing timer 6 fe:1a:4a:24:27:a0 yes 0.00 This is, the actual virtual host's MAC address is missing from the bridge. We haven't been able to find a detailed explanation on how the network internals of oVirt should work but hopefully someone in this list can point us to the right resource. Thank you. Xavier.

oVirt 3.5 on RHEL 6.6 hyperv enabled breaks Windows VMs
by Charles Gruener 28 Oct '14

28 Oct '14

https://bugzilla.redhat.com/show_bug.cgi?id=1110305 This enabled the hv_relaxed flag on all my Windows VMs, causing them to no longer boot. The same thing would happen if I simply booted from the Windows install media. I would get a screen with a stop error: Your PC needs to restart. Please hold down the power button. Error Code: 0x0000001E Parameters: 0xFFFFFFFFC0000096 0xFFFFF802C4044EA4 0x00000000000000000 0x00000000000000000 I created a file called /etc/ovirt-engine/osinfo.conf.d/01-windows.properties that had one line: os.windows_xp.devices.hyperv.enabled.value = false I restarted ovirt-engine and now I can start my Windows VMs. Why does this occur? Is it because I upgraded from 3.4 to 3.5? Is there something else I'm doing wrong? I would like to not need this workaround. Thanks. Charles

3.5 install issues: failed to setup ovirtmgmt

--Sig_/UCS9Qt+.3XGZ4pTqVuU5k2x Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: quoted-printable I'm on my 4th attempt to get a 3.5 hosted-engine set up on CentOS 6.5.
