I'm using kvm
on Ubuntu 16.04
my machine cpu is 24 core and I run 47 sandbox using hyperthreading on kvm
.
The virtual machine use 0.5 core physically
After a few minutes of running kvm
, the following message pops up.
I entered iostat
, it comes out
avg-cpu: %user %nice %system %iowait %steal %idle
46.42 0.00 5.87 6.87 0.00 40.83
my kernel is 4.4.0-38-generic
Please tell me what causes this kind of error (CPU lockup), and what should my next steps be?
