Hello Alexandre,

Guest: 64bit Ubuntu 12.04 server istalled from iso with only SSH
Cache filled by:
find /usr -type f -print0 | xargs -0 cat >/dev/null

Guest config:
bootdisk: scsi0
cores: 1
ide2: isoimages:iso/ubuntu-12.04.1-server-amd64.iso,media=cdrom,size=673068K
localtime: 1
memory: 1024
name: testmigrate
net0: virtio=5A:69:3B:F8:6C:FD,bridge=vmbr0,rate=100
net1: virtio=6E:CF:0A:D7:12:4E,bridge=vmbr1
ostype: l26
scsihw: virtio-scsi-pci

virtio0: 
cephkvmpool1:vm-105-disk-1,iops_rd=215,iops_wr=155,mbps_rd=130,mbps_wr=90,size=20G

Host is running latest git version and a vanilla 3.7.1 kernel but i 
tested proxmox pve kernel too - no difference.

Thanks!

Greets,
Stefan
