i'm using libvirt/kvm/qemu on a stable Debian Linux KVM 4.9.0-6-amd64 .

qemu-kvm : 1:2.8+dfsg-6+deb9u5
libvirt-daemon : 3.0.0-4+deb9u3
libvirt-clients : 3.0.0-4+deb9u3
virt-manager : 1:1.4.0-5
virt-viewer : 5.0-1
virtinst : 1:1.4.0-5

My guests are made with this kind of command line :

virt-install --connect=qemu:///system --name=debian --ram=2048 --disk 
--network=bridge:bridge-0-3,model=virtio --accelerate --noautoconsole 
--vnc --vnclisten= --keymap=fr 
--cdrom=/home/iso/debian-6.0.1a-i386-netinst.iso --os-type=linux 
--os-variant=debiansqueeze --hvm

Since a long time ago now (may be a Debian upgrade) i noticed that ssh 
session from my personal PC to guests are very slow (connection and 

My ssh configuration is the same on all my real/vm servers.
The problem occure only on my guest.

Have you got a solution or an idea to solve this problem ?

Thanks for your help
