I've run DRBD inside virtual guests as well as on a virtual hosts - both without issues. It depends on your use case. <BR>
<BR>
It sounded to me like Antonio was planning on running DRBD in two VMs that he has to do P-to-V migrations on.<BR>

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

​​Hi list:<BR>
<BR>
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?<BR>
<BR>
I hope your answers.<BR>
<BR>
Thanks in advance.<BR>
<BR>
Regards,<BR>
<BR>
Antonio.​
