Hi, I have an oVirt 3.5.6 platform using hosted-engine setup. I installed my engine's VM with 2Gb of memory at the beginning, now I want to add 2Gb I've modified /etc/ovirt-hosted-engine/vm.conf on my hypervisors the VM is booting with 4Gb of memory (free -m), but the GUI is still showing 2Gb I tried engine-setup but I get this error [ INFO ] Cleaning async tasks and compensations [ ERROR ] Failed to execute stage 'Setup validation': '36' [ INFO ] Stage: Clean up Log file is located at /var/log/ovirt-engine/setup/ovirt-engine-setup-20151210124227-xrr3g5.log [ INFO ] Generating answer file '/var/lib/ovirt-engine/setup/answers/20151210124820-setup.conf' [ INFO ] Stage: Pre-termination [ INFO ] Stage: Termination [ ERROR ] Execution of setup failed Here is the tailf log 2015-12-10 12:48:20 DEBUG otopi.context context.dumpEnvironment:500 ENV OVESETUP_WSP_RPMDISRO_PACKAGES_SETUP=str:'ovirt-engine-setup-plugin-websocket-proxy' 2015-12-10 12:48:20 DEBUG otopi.context context.dumpEnvironment:500 ENV PACKAGER/keepAliveInterval=int:'30' 2015-12-10 12:48:20 DEBUG otopi.context context.dumpEnvironment:500 ENV PACKAGER/yumDisabledPlugins=list:'[]' 2015-12-10 12:48:20 DEBUG otopi.context context.dumpEnvironment:500 ENV PACKAGER/yumEnabledPlugins=list:'[]' 2015-12-10 12:48:20 DEBUG otopi.context context.dumpEnvironment:500 ENV PACKAGER/yumExpireCache=bool:'True' 2015-12-10 12:48:20 DEBUG otopi.context context.dumpEnvironment:500 ENV PACKAGER/yumRollback=bool:'True' 2015-12-10 12:48:20 DEBUG otopi.context context.dumpEnvironment:500 ENV PACKAGER/yumpackagerEnabled=bool:'True' 2015-12-10 12:48:20 DEBUG otopi.context context.dumpEnvironment:500 ENV SYSTEM/clockMaxGap=int:'5' 2015-12-10 12:48:20 DEBUG otopi.context context.dumpEnvironment:500 ENV SYSTEM/clockSet=bool:'False' 2015-12-10 12:48:20 DEBUG otopi.context context.dumpEnvironment:500 ENV SYSTEM/commandPath=str:'/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin' 2015-12-10 12:48:20 DEBUG otopi.context context.dumpEnvironment:500 ENV SYSTEM/reboot=bool:'False' 2015-12-10 12:48:20 DEBUG otopi.context context.dumpEnvironment:500 ENV SYSTEM/rebootAllow=bool:'True' 2015-12-10 12:48:20 DEBUG otopi.context context.dumpEnvironment:500 ENV SYSTEM/rebootDeferTime=int:'10' 2015-12-10 12:48:20 DEBUG otopi.context context.dumpEnvironment:504 ENVIRONMENT DUMP - END 2015-12-10 12:48:20 DEBUG otopi.context context._executeMethod:138 Stage pre-terminate METHOD otopi.plugins.otopi.dialog.cli.Plugin._pre_terminate 2015-12-10 12:48:20 DEBUG otopi.context context._executeMethod:144 condition False 2015-12-10 12:48:20 INFO otopi.context context.runSequence:417 Stage: Termination 2015-12-10 12:48:20 DEBUG otopi.context context.runSequence:421 STAGE terminate 2015-12-10 12:48:20 DEBUG otopi.context context._executeMethod:138 Stage terminate METHOD otopi.plugins.ovirt_engine_common.base.core.misc.Plugin._terminate 2015-12-10 12:48:20 ERROR otopi.plugins.ovirt_engine_common.base.core.misc misc._terminate:151 Execution of setup failed 2015-12-10 12:48:20 DEBUG otopi.context context._executeMethod:138 Stage terminate METHOD otopi.plugins.otopi.dialog.human.Plugin._terminate 2015-12-10 12:48:20 DEBUG otopi.context context._executeMethod:138 Stage terminate METHOD otopi.plugins.otopi.dialog.machine.Plugin._terminate 2015-12-10 12:48:20 DEBUG otopi.context context._executeMethod:144 condition False 2015-12-10 12:48:20 DEBUG otopi.context context._executeMethod:138 Stage terminate METHOD otopi.plugins.otopi.core.log.Plugin._terminate - What is the correct way to modify the engine's VM memory Thanks in advance.
