Failed to start Dreamview in a virtualized Ubuntu host

[alhezmi72]

I installed Apollo 8.0 in an Ubuntu virtual machine and tried going through the [https://github.com/ApolloAuto/apollo/blob/master/docs/02_Quick%20Start/apollo_8_0_quick_start.md](Apollo 8.0 Quick Start Guide) and updated the ports and DreamView IP:Port as per the recommendation stated above, but I got the same error message: [ERROR] Failed to start Dreamview. Please check /opt/apollo/neo/data/log/dreamview.log or /opt/apollo/neo/data/log/monitor.log for more information

Output of the log file: /opt/apollo/neo/data/log/dreamview-dev.log

兄弟你解决了吗，跟你一模一样的问题

[alhezmi72]

No, I could not! I could run the simulator only on a non-virtualized Ubuntu machine, but not in a VM.

The cause of the error cannot be determined from the log you provided. Please start dreamview_plus again. If the startup fails, please execute the following two commands respectively and take screenshots of the output. I will continue to judge "tail -500f data/log/dreamview_plus.INFO" and "mainboard -d /apollo/modules/monitor/dag/monitor.dag"

Thanks for your feedback! The error message is still there!

In fact, I have under the log directory only two log files: $>cd data/log dreamview-dev.log monitor-dev.log But I do not see the file: dreamview_plus.INFO

When I run the tail command: tail -500f data/log/dreamview-dev.log The initial logged messages are printed, but when I tried running the dreamview aem bootstrap start from a second screen, nothing is printed in the tail screen.

Regarding the second command, when I try running this command, the following output is prompted: $>mainboard -d /apollo/modules/monitor/dag/monitor.dag
