CentOS-6.4_x86_64
I have a KVM virtual machine (several actually) which acts as a warm spare for another kvm instance running on a different physical host. Each hour it backs up the live system using rsync. This morning I discovered that the backup instance was running at 99% utilisation and that the process consuming the entire virtual cpu was this:
sh -c rpm -q -a --queryformat "%{NAME}\n%{VERSION}-%{RELEASE}\n%{EPOCH}\n%{GROUP}\n%{SUMMARY}\n\n" 2>/dev/null
In fact there were two identical instances of these processes, one the parent of the other.
The vm instance does not have access to the internet as its physical host is connected to the physical host of the live kvm using a x-over patch cable.
Where is this process started from? What does it do? And why is it consuming so much cpu.?
Does anyone here have any ideas?
