For the best debug I describe my installation:
I have installed 2 node with the 1.4 b2 iso. So I have reduced the default pve/data lvm and then created a new lvm that I'm using for drbd.
So the new pve/lvmdrbd lvm is the backend disk for drbd itself (/dev/drbd1).
On /dev/drbd1 I have created a new volume group and I inserted it in the master node through web interface (Add LVM Group - check shared).
Is it correct?

Could you explain me how it works?
What is the process that manages it?
There are some configuration files?
Thanks.

Another information that I'm verifying now: before migration I opened a command prompt in the vm and I inserted the command "ping -t 192.168.1.1" (192.168.1.1 is my router), and in my notebook the command "ping -r 192.168.1.20" (192.168.1.20 is the vm). During the migration I see in my notebook that I lose 5 ping (it is normal) and when the vm is completely migrated the ping return. In the destination host I see that the cpu load is low: I believe that the vm is working well. If open the vnc console of the vm I see that the ping command that I have inserted is working correctly but if I move the cursor the vm freezes, the host's cpu load increases until 100% and after few seconds blue screen appears.
It seems that there is a problem with the virtual video card or with the virtual mouse/keyboard.
What could it be?
So you use LVM on top of DRBD on top of a lvm volume??
DISK-partition/LVM/DRBD/LVM
Instead I would use a partition directly
DISK-partition/DRBD/LVM

When we modify shared storage metadata we do:
Code:
ssh master pvesm lock <STORAGE_ID>pvesm implements a simple locking protocol.

I have the same problem, but on DRBD.

However, I still didn't test without virtio.

So the problem is with the version of KVM, right?
I see that in 1.4 beta2 it is implemented the 0.11.0 KVM version.
Do you believe that with older version of proxmox I resolve?
What version of KVM is in proxmox 1.4 b1?
And in 1.3?
Thansk a lot for the support.

But in the Roadmap description of 1.4 b1 I see 'Zero downtime live migration (KVM) over ssh channel - all traffic is encrypted'; what version of KVM is here?

Can I remove the pve-qemu-kvm and install the qemu-kvm that I find in linux-kvm.org?
There is any dependency with other packages?
