Template Clone/Independent vs Thin/Dependent
by Shanil S 24 Oct '14

24 Oct '14

Hi, I am using the ovirt 3.5 and when i create VM from the template through Ovirt web portal, it displays Template is "Clone/Independent"but with the same template When i create through REST API, it shows "Thin/Dependent"... I Found one email thread ( https://www.mail-archive.com/users@ovirt.org/msg21271.html ) from the community for the same issue but even using their method still it display the same "Thin/Dependent". I am using the following xml :- <vm> <name>$name</name> <cluster> <name>phase1</name> </cluster> <cpu> <topology cores='$core' sockets='$socket'/> </cpu> <memory>$memory</memory> <template> <name>$templatetype</name> </template> <disks> <clone>true</clone> </disks> </vm> I have attached the screen shots , please check it. -- Regards Shanil

Ovirt 3.5 VDSM Crashing on Networknames ?
by Matt . 24 Oct '14

24 Oct '14

I'm having a very strange issue on (some) VDSM hosts. Host is going down and VM's cannot find disk while booting, what do my logs show: vdsmd_init_common.sh: libvirt: Network Driver error : Network not found: no network with matching name 'vdsm-NETNAME' When it see this, all networks are brought down it seems. Anyone seeing this and knows why this happens ? Libvirt is 1.1.1 Cheers, Matt

Change password using ovrt api is not working
by Shanil S 23 Oct '14

23 Oct '14

Hi, Currently i have updated the ovirt version to 3.5 and after that the reset password using api is not working but there isn't any errors returned. The following xml is i used for the reset password and it was working with the previous version <action> <vm> <os> <boot dev='cdrom'/> </os> <initialization> <cloud_init> <users> <user> <user_name>root</user_name> <password>$newpass</password> </user> </users> </cloud_init> </initialization> </vm> </action> Could you please have a look at the above xml ? Is there anything modified in the new version ? The reset password is working fine from the ovirt admin panel and the issue is only when we use the ovirt api to reset the password. -- Regards Shanil

Upgrading all-in-one 3.4.4 to 3.5 on fedora 19
by Gianluca Cecchi 23 Oct '14

23 Oct '14

Hello, I have an all-in-one 3.4.4 installation on F19. Currently my network config under /etc/sysconfig/network-scripts: $ cat ifcfg-ovirtmgmt DEVICE=ovirtmgmt ONBOOT=yes TYPE=Bridge DELAY=0 IPADDR=192.168.1.101 NETMASK=255.255.255.0 GATEWAY=192.168.1.1 BOOTPROTO=none NM_CONTROLLED=no $ cat ifcfg-p10p1 DEVICE=p10p1 ONBOOT=yes HWADDR=90:e6:ba:c9:f1:e1 BRIDGE=ovirtmgmt NM_CONTROLLED=no If I upgrade to 3.5.0 would it convert into the new default network unified persistence or should I keep net_persistence = ifcfg in my vdsm.conf for all-in-one installations? Will NetworkManager still kept off after upgrade? I suppose vnic profiles that I use for natting some of the VMs, using extnet vdsm hook will be preserved, correct? Thanks in advance, Gianluca

iSCSI connection to a LUN - EMC CX4-120 - Login OK but no LUN
by Nicolas Ecarnot 23 Oct '14

23 Oct '14

Hi, Setting up our third oVirt infra, we are now connecting it to an EMC CX4-120 SAN. On this SAN, we have set up a classical storage group, added the authorized hosts, registered them. On the oVirt side, we want to create the first master storage domain and so we give the GUI the right SAN ip, and the iSCSI connection is working. We see appearing the two virtual IP of the storage processors (A and B), and the login button reacts well, no error appears. But no LUN shows up at this point. Looking at the hosts used by this connection, it appears that the iSCSI connection worked well, and that the LUN is visible on the host side ("iscsiadm -m session -P3"). So now, in the web GUI, there is no LUN showing up I could connect to. I have isolated the relevant logs - the engine one and the vdsm one : Engine : http://pastebin.com/32Sg85C8 VDSM : http://pastebin.com/BbY6mVSk I don't know what is missing? May you help me? -- Nicolas Ecarnot

Fwd: Are there some general strategyhow to Iscsi strorage domain?

---------- Forwarded message ---------- From: Arman Khalatyan <arm2arm(a)gmail.com> Date: Thu, Oct 23, 2014 at 10:11 AM Subject: Re: [ovirt-users] Are there some general strategyhow to Iscsi strorage domain? To: Trey Dockendorf <treydock(a)gmail.com> Thank you Trey for sharing your setup. I have also one test system with zvol exported with iscsi over 10G. Unfortunately the difference in performance of zfs over raid controller is huge, particularly where VM running mysql. I did not try HBAs yet, I have only LSI/Adaptec/Areca RaidControllers they dont have IT mode. Maybe that can be the reason. For sure always one need to find the sweet edge between performance and reliability. Just for comparison with yours I get on random IO: zvol/16Disks/Raid2/tgtd/iscsi/10G-> on VM multiple rsync - ~100-150MB/s, Same HW but disks with Areca RAID6 - 650MB/s stable even more in some cases. The best performance I got on FDR iser-> 80% of bare metal performance: 1500MB/s but ovirt goes mad claiming that Network and Disk devices are saturated. My VM goes time by time to paused state. It is due to that the Ovirt treating all ib devices as 10Gbit cards(in terms of speed).:( On Thu, Oct 23, 2014 at 8:30 AM, Trey Dockendorf <treydock(a)gmail.com> wrote: > Not sure if it's a solution for you, but ZFS.
