Configuring your disks is really two parts
- where should the KVM host be installed
- where will you store the KVM guests filesystem images
KVM host
I have two identical 16G SSD disks. The partition layout is
sda 16G sda1 256M type=fd sda2 15360M type=fd sdb 16G sdb1 256M type=fd sdb2 15360M type=fd
Raid
md0 raid1 sda1 sdb1 md1 raid1 sda2 sdb2
Luks
md1 luks formatted
LVM
md1 is configured as lvm with a volumegroup called vg1
with two partitons
For my system I have two small SSD disks. They are 16G each. I will use those to install the KVM host on.
