Hi, i would like to know why my machine has 2 process for each VM was configured at startup.

htop (for VM dn1)

/usr/bin/kvm -S -M pc-0.12 -enable-kvm -m 1000 -smp 1 -name dn1 -uuid 3ddc38bc-3d62-8a17-0abb-1ec73e983d0e -chardev socket,id=mon
/usr/bin/kvm -S -M pc-0.12 -enable-kvm -m 1000 -smp 1 -name dn1 -uuid 3ddc38bc-3d62-8a17-0abb-1ec73e983d0e -chardev socket,id=mon

will it consume the double of the assigned memory? Could it be a failure on my configuration or it is the default behaviour?

Many thanks in advance

How are you managing your kvm virtual machines? What tool are you using?

This is by design and it's the default behaviour of KVM. You don't have a configuration issue and it will not consume twice the amount of the assigned memory.
