[Xen-users] High Number of VMs

[Ciro Iriarte <cyruspy@xxxxxxxxx>]

Hi, I'm curious about how you guys deal with big virtualization
installations. To this date we only dealt with a small number of VM's
(~10)on not too big hardware (2xquad xeons+16GB ram). As I'm the
"storage guy" I find it quite convenient to present to the dom0s one
LUN per VM that makes live migration possible but without the cluster
file system or cLVM complexity. The thing is that Linux has a 255 SCSI
device limit apparently (255/2= ~128 with multipath) and that won't
scale in big installations (300 VMs for example).

Any experiences on this scale?

Regards,
