[Users] Ovirt Memory Page Sharing or to less memory

[Noam Slomianko]

I stand corrected, it seems that this change is supported.
If you go and check the memory optimisation tab you'll find that it is set to "Custom Value"

Short answer: not really

Long answer: you can go in to the engine DB -> 'vds_groups' (clusters) table and change the 'max_vds_memory_over_commit' column to what ever value you like.
Word of caution: This isn't supported, and i cannot guarantee how will the Ovirt UI or the Host react to this change

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
