Hello, On our 3.8 dual-node ONE I got this morning a OVERLOADED node with load average of 35.
I found one my own VMs eating 99% CPU, it was just booted and waiting
at ISO boot menu prompt.
It looks to be related to KVM as I reproduce it on a 4.2.
I can reproduce it by defining a template using an Ubuntu Server AMD64 ISO
and instanciate it.
I just let the VMs at ISO boot menu, and the KVM process quickly eat 99%
of CPU.
If someone has an idea.
Here is the template:
oneadmin@nebula:~$ onetemplate show 17
