Hi,

you can avoid this check in the engine by running this db script: update vdc_options set option_value = false where option_name = 'EnableSwapCheck'; don't forget to restart your jboss.

Thanks, Gilad.

what does this error mean? HOST or guest swap too much disk space? thanks

A swapping host in most cases have a major impact on VM behavior. So by default oVirt will not run a VM on a swapping host. this is highly unrecommended.

this is a protection mechanism if memory overcommit is overwhelming ability to compensate via ksm (and later ballooning). how much RAM on your host? how much vram (total ram allocated to VMs) on it?
