When i start my two mysql-cluster vms they will use the 256 PMG plus 3,75 GB MS they have defined a max of 4 GB MS. At this poitn now the problem begins the mysql taken the hole memory in both vms and now there is no more free ram at the host and it is not possible to start more vms. (this is also speculation im not a expert) So i need for my understanding a higher rate of memory overcommit to be able to start all vms, and for that the host must use the swap to have enough memory for overcomit to start all vms and yes the higher the rate, the worse the performance. I'm not sure if this is the right or good way tho fix this problem (sorry for my bad english I hope this is understandable)

[Users] Ovirt Memory Page Sharing or to less memory
by Mathok 18 Oct '12

18 Oct '12

Hello, I have only 3 host with less amount of memory for test purpose and i like to run more vms but i cant start them because they are under the defined memory threshold. It is possible to increase the level of memory page sharing on a cluster above the 200% with a option and start the vms after that change ? or it is possible to deactivate the memory threshold with any option? regards mathok

[Users] database issue after power failure
by Neil 16 Oct '12

16 Oct '12

Hi guys, I've got what looks like a huge issue after a power failure. In my server.log I'm seeing "Caused by: org.postgresql.util.PSQLException: FATAL: database "engine" does not exist" in my server.log and in my engine.log I'm seeing the following which also looks very bad. "2012-10-15 09:08:41,357 ERROR [org.ovirt.engine.core.bll.Backend] (MSC service thread 1-4) Error in getting DB connection. The database is inaccessible. Original exception is: DataAccessResourceFailureException: Error retreiving database metadata; nested exception is org.springframework.jdbc.support.MetaDataAccessException: Could not get Connection for extracting meta data; nested exception is org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is java.sql.SQLException: javax.resource.ResourceException: IJ000453: Unable to get managed connection for java:/ENGINEDataSource" Please could someone assist if possible, I'm currently logged in on #ovirt as well. Thanks. Regards. Neil Wilson.

[Users] ovirt node - cant start spice
by Yuriy Demchenko 15 Oct '12

15 Oct '12

Hi, I've recently installed ovirt-node-2.5.2 and now have trouble starting VM with spice as console: > unsupported configuration: spice secure channels set in XML > configuration, but TLS is disabled in qemu.conf How can i fix this? Also, what I didn't get is how to log in to node via ssh to get normal console, not to "admin interface", is it even possible? -- Yuriy Demchenko
