[DRBD-user] DRBD on virtual machine

[Dennis Jacobfeuerborn]

What specifically don't you get about this? The features DRBD provides
are no different when running in a virtual machine so I'm not sure what
you think makes this fundamentally problematic?

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.
