[Users] Replacing ISO domain
by Gabi C 10 Jan '14

10 Jan '14

Hello! 1 Ovirt-engine + 2 nodes with Glusterfs on them (replicate), 1 ISO domain, 1 Export domain. ISO domain is created at ovirt-setup time on ovirt-engine host.How can I replace this ISO domain with a new, bigger, one on another machine?

[Users] Creation of preallocated disk with Gluster replication
by gregoire.leroy＠retenodus.net 10 Jan '14

10 Jan '14

Hello, I have a Gluster volume in distributed/replicated mode. I have 2 hosts. When I try to create a VM with a preallocated disk, it uses 100% of the available CPU and bandwidth (I have 1 Gigabit network card). The result is I can't even create a preallocated disk because the engine detects a network failure. I get that kind of messages in /var/log/messages : " Jan 2 14:13:54 localhost sanlock[3811]: 2014-01-02 14:13:54+0100 167737 [3811]: s4 kill 21114 sig 15 count 1 Jan 2 14:13:54 localhost wdmd[3800]: test failed rem 51 now 167737 ping 167718 close 167728 renewal 167657 expire 167737 client 3811 sanlock_ef4978d6-5711-4e01-a0ec-7ffbd9 cdbe5d:1 " And that in the Ovirt Gui : " 2014-janv.-02, 15:35 Operation Add-Disk failed to complete. 2014-janv.-02, 15:35 Storage Pool Manager runs on Host HOST2 (Address: X.X.X.X). 2014-janv.-02, 15:35 Invalid status on Data Center GlusterSewan.

I understand that the creation of a 10 Go disk image generates a lot of traffic, but is there a way to limit it so that it doesn't have an impact on the production ? Furthermore, Why does it use so much CPU ressources ? I can see on my monitoring graph a big peak of CPU usage when I launched the operation (probably until 100%). Thank you, Regards, Grégoire Leroy

Re: [Users] VSDM?s logrotate makes Hosts fill up var, eventually
by Juan Pablo Lorier 10 Jan '14

Hi Dan, If my opinion is worth, I use logs all the time as my setup is evolving all the time and have issues quite often, so I rather use space in logging too much than loose information I need in regular bases. Regards,

So be warned: if you have this hardware check very carefully your network mount points inside Vms If you have already tested this configuration and have this working please let me know.

[Users] Specifying values for cert, key, and CA for ovirt-shell
by Bob Doolittle 09 Jan '14

09 Jan '14

Hi, I want to run ovirt-shell directly (as root) on the Engine. Presumably all the files I need for CA, key, and cert are in the /etc/pki area. But when I use the attached .ovirtshellrc file I get: error: [Errno 336265218] _ssl.c:341: error:140B0002:SSL routines:SSL_CTX_use_PrivateKey_file:system lib How can I specify an appropriate configuration to get this working? I would prefer to keep using SSL if possible. Thanks, Bob

[Users] Bug? in tweak vm instance via REST/JSON 3.3.2
by Sven Kieske 09 Jan '14

09 Jan '14

Hi, we got a problem with starting a vm after changing some of its parameters via REST (JSON) this is the command to create the vm (this works): POST request on https://virt-mgmt-01.internal/api/vms/ {"name":"vr00002","cluster":{"id":"2ad11b5e-9e74-499a-b317-5a9a3027cfca"},"template":{"id":"374a12df-5ffc-4feb-a2bf-c912f059675f"}} Then we tweak memory and cpu: PUT request on https://virt-mgmt-01.internal/api/vms/42dba82f-e7ea-40ff-a76e-70056912b47f {"memory":2048,"cpu":{"topology":{"sockets":1,"cores":1}}} and then we start it: POST request on https://virt-mgmt-01.internal/api/vms/42dba82f-e7ea-40ff-a76e-70056912b47f/… {"vm":{"initialization":{"cloudInit":{"host":{"address":"vr00002"},"networkConfiguration":{"nics":{"nics":[{"name":"eth0","bootProtocol":"STATIC","network":{"ip":{"address":"10.0.1.12","netmask":"255.255.255.252","gateway":"10.0.1.9"}},"onBoot":true}]},"dns":{"servers":{"hosts":[{"address":"46.30.62.99"},{"address":"46.30.62.98"},{"address":"46.30.62.97"}]}}},"users":{"users":[{"name":"root","password":"lPzYG06qV63+Tne7"},{"name":"vr00002","password":"lPzYG06qV63+Tne7"}]},"files":{"files":[{"name":"\/foo\/ip-configuration","content":"extern_v4address1 185.15.194.7\npassword1 lPzYG06qV63+Tne7","type":"PLAINTEXT"}]}}}}} the error we get: Operation Failed","detail":"[Cannot run VM. There is no host that satisfies current scheduling constraints. See bellow for details:]" when we start the vm without altering memory and cpu it starts just fine. Is this not supported via JSON, or is this a bug? PS: BTW there seems to be a spelling bug in the error message ("bellow"). -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.

[Users] Experience with low cost NFS-Storage as VM-Storage?
by Sven Kieske 09 Jan '14

09 Jan '14

Hi, I'd like to ask around if someone does run oVirt with NFS backed Storage provided by simple servers (no SAN or NAS) and what your experience is so far? In particular I'm interested what happens if there is a connection loss to the NFS-Volume. How does this affect running vms and the compute nodes they run on? I suspect they would first write their changes to RAM instead of virtual HDD. But once the RAM is full, does just the vm become unresponsive or does the whole compute node die? I couldn't test this yet myself, but my limited experience with NFS-Servers tells me, that they become unresponsive if they are under heavy load and I'd like to know how this affects the vms and computenode. Thanks! PS: Bonus question: Does someone utilize the NFS-Servers also as computenodes ? -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.
