[Bug 578930] [NEW] Lucid qemu-kvm: ksmd default config is CPU hog

[lequeux1]

Public bug reported:

Binary package hint: qemu-kvm

Lucid 64 bits


Expected: have qemu-kvm propose adquate default values
Found: using kvm, running 2 VMs , ksmd constantly eats 20 to 30%CPU

Lucid script used to tune ksm (/etc/init.d/qemu-kvm , parms in /etc/init
/qemu-kvm.conf)  doesnt provides adequate values IMHO

-> Suggest modify qemu-kvm.conf
 either to deactivate ksm
 or have 200 for SLEEP_MILLISECONDS

Similar issue found on proxmox (debian) proposing default values:
