[ovirt-users] engine tries to allocate 11GB and aborts (was: hosted engine does not start correctly (CentOS 7.1, overt-engine 3.5.2))

I managed to complete the “engine-backup —mode=restore…” step, and the following “engine-setup” step appear to have completed. However, the ovirt-engine service was not started successfully has errors: [root@ovirt ~]# systemctl status ovirt-engine ovirt-engine.service - oVirt Engine Loaded: loaded (/usr/lib/systemd/system/ovirt-engine.service; enabled) Active: failed (Result: exit-code) since Mon 2015-05-25 22:26:12 PDT; 43s ago Main PID: 15931 (code=exited, status=1/FAILURE) May 25 22:26:11 ovirt.polysep.ucla.edu systemd[1]: Started oVirt Engine.

Hint: Some lines were ellipsized, use -l to show in full. Additionally, /var/log/ovirt-engine/console.log complains “cannot allocate memory”. The VM engine has 4GB of memory, but ovirt-engine engine seems to want ~11GB of memory, is that right? [root@ovirt ~]# cat /var/log/ovirt-engine/console.log OpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(0x0000000412180000, 11250696192, 0) failed; error='Cannot allocate memory' (errno=12) # # There is insufficient memory for the Java Runtime Environment to continue. # Native memory allocation (malloc) failed to allocate 11250696192 bytes for committing reserved memory. # An error report file with more information is saved as: # /tmp/jvm-15974/hs_error.log [root@ovirt ~]# free -m total used free shared buff/cache available Mem: 3791 123 3175 28 492 3428 Swap: 2559 0 2559 [root@ovirt ~]# The hs_error.log is attached. Any help is appreciated.
