<font style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">I continue to see people run DRDB clusters as VM guests. I personally don't get this. The only reason to do this is as a proof of concept and not for production. I run a DRDB cluster
as a source of data storage system for a virtualization environment. It is based on physical machines for maximum performance. Depending on the I/O requirements of the DRBD system and it's applications running underneath it could make it very difficult for
the virtualization hosts to supply the necessary I/O capability to support the required load.<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>
