CentOS 5.9 VM crash when running under VBox 5.1.22

Reported by: IrishGold Owned by:
Component: other Version: VirtualBox 5.1.22
Keywords: NMI watchdog Cc:
Guest type: Linux Host type: Linux


Hi there,

I have a CentOS 7 machine (Kernel 3.10.0-327.18.2.el7.x86_64) with VirtualBox.

Until Today I had VirtualBox 5.0.32 r112930 (package VirtualBox-5.0-5.0.32_112930_el7-1.x86_64) installed and three VM running: two CentOS 5.9 (Kernel 2.6.18-194.3.1.el5) and one Windows XP.

Today, after installing VirtualBox 5.1.22 (package VirtualBox-5.1-5.1.22_115126_el7-1.x86_64.rpm) and the sister extension package, one of the CentOS crashed with kernel panic "Kernel Panic - Not syncing: NMI watchdog" message.

Find herein a ZIP file containing two files:

  1. The image of the machine’s console at the time of the crash, and
  2. The Vbox.log from the server with 5.1.22 after the VM crashed

Thanks for your help/support.

I don't mean to hurry you, but since the VM is my IP-PABX I'm currently without phone system.

I just would like to know whether you need any more info, log, whatever before I go back to VBox 5.0. A quick answer to this specific question would be very much appreciated.

Thanks for your understanding + support.

Could you add the following parameters to the kernel command line of your CentOS 5.9 images: divider=10 nmi_watchdog=0. You need to add these parameters most likely to /boot/grub/grub.conf.

Indeed now it works. Thanks.

I would appreciate it very much if you could explain the logic behind it. Thanks.

We have seen this kind of guest problem with EL5 kernels with other versions of VirtualBox as well. See also  here.
