VirtualBox freeze my system

[sed_faster]

Hello folks,

I have this environment with virtual box:


$ uname -a
Linux user 4.15.0-22-generic #24-Ubuntu SMP Wed May 16 12:15:17 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04.1 LTS
Release: 18.04
Codename: bionic
$ virtualbox --help
Oracle VM VirtualBox Manager 5.2.10_Ubuntu


After I startup a simple VM with Winxp or Win10 my system simply freeze. This situation didn't occur right after the VM startup. This occur more a less 3 minutes after VM started. To solve this I press ctrl+alt+F1 and accessed screen number 1 (command line). After this I press ctrl+alt+F7 and come back my gui (LXDE). After I do this simply but annoying task the system unleashes.

How can I solve this situation?
These values do not always occur, but of the several times the system freezes and I perform the steps I spoke I was able to capture these values: https://imgur.com/a/4O0aFui

Thanks

log files? Use journalctl to get the relevant ones using a timescale.

Years ago, I had an issue with vbox refusing to run on an brand new ubuntu system. It was lock up the host completely.
That same, exact, hardware has been running kvm + libvirt since about 3 days later 24/7/365 with 10-20 VMs all this time. KVM is maintained by the Linux kernel team, not a 3rd party team. Just sayin', for you consideration.

I consulted journalctl but I can't understand what this file has and where I should look:



$ journalctl -r

Between nov 05 03:40 and nov 05 03:48 I started VM win 7 and this process, through virtual 5.2.10 crashed 3 times. All times to unlock the system I hat to did this process:

1-Ctrl+F1
2-Ctrl+F7

I changed between a command line and graphic mode. What should I do?
Thanks

As this sounds like a problem I had with my own setup (lubuntu 18.04.1 + virtualbox version 5.2.10_Ubuntu r121806), can you please explain in which way your system freezes?
Are you able to move your mouse but clicks are not recognized?

If so, can you please check if your system is back to normal if you hit Host Key (which should be right ctrl if unchanged) + F twice? (First time to enter fullscreen mode of VM + second time to exit fullscreen mode)

If this "revives" your machine than you have probably the same issue as me.

You can try the steps mentioned in this post: https://ubuntuforums.org/showthread.php?t=2395969&p=13814509#post13814509

Keep me updated if it solves your problem.
Cheers ;)

I'm really glad that my tip helped you! It is quite interesting to see that my workaround also helps other people. =)

You are very much welcome ;)
