[Gluster-users] about HA infrastructure for hypervisors

You should indeed to use the same server running as a storage brick as a KVM host to maximize hardware and power usage. Only thing I am not sure is if you can limit the amount of host memory Gluster can eat so most of it gets reserved for the Virtual Machines.

Good point. While abtracting we decided to seperate KVM & Gluster but I can't remember why.
We'll think about that again.

Ok! Thanks.
