[ovirt-users] hosted engine does not start correctly (CentOS 7.1, overt-engine 3.5.2)

[Haoyang Haven Liu]

Hello,

I tried to follow <http://www.ovirt.org/Migrate_to_Hosted_Engine <http://www.ovirt.org/Migrate_to_Hosted_Engine>> to migrate an existing ovirt environment. 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 at ovirt ~]# systemctl status ovirt-engine
ovirt-engine.service - oVirt Engine

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 at 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)

Swap:          2559           0        2559
[root at ovirt ~]# 

The hs_error.log is attached.

Any help is appreciated.

Haven
