What services do you want to have in the server?, and
At peak times, how many speed of write do you need?
(If you don't need speed for write of blocks of disk and network, DRBD can be
installed in the guest).
Also you can search by Internet the benchmarks of virtio-block and virtio-net.

Hi list:
Firstly thanks for your replies.
Supposed to be worse performance using VM but, is so dramatic?
Now I have a physical architecture with HA and I plan migrate these to VM
with another hosting provider. I think that with RAM, CPU and storage there
will be no problem ...
Do you need more
@Antonio:
The problem is that the VMs don't have the network performance that have the
host (virtio-net is for excellence the best), by a great difference, virtio.net
never will have the performance of a host. Now is in development a new
technology: " virtio-blk dataplane" and "virto-net datapl
I've run DRBD inside virtual guests as well as on a virtual hosts - both
without issues. It depends on your use case.
It sounded to me like Antonio was planning on running DRBD in two VMs
that he has to do P-to-V migrations on.

But DRBD must be running in the host, not in the guest (VM).

I don't know of a reason you wouldn't want to run DRBD on a VM. I've had
no issues doing so.

Hi list:
I need your help ... I have to migrate two physical servers with
DRBD+Pacemaker+Corosync to virtual machines. On the new set of virtual
machines I will can manage more hardware resources but, do you have any
reason advise against using DRBD on virtual machines?
I hope your answers.
