This entry is part 10 of 10 in the series LJDT - Linux Just Does That

Have you ever wanted to resize a disk in a VM and wondered how insanely painful that would be? After all, from the old days of platter-based spinning drives in computers (sorry to those of you still living in those days), before SANs with resizable LUNs, file-backed VMs, and other marvels of recent times, disks didn’t magically resize themselves unless it was to get smaller because they were breaking/broken. As a result, OS’s have learned to handle bad sectors by avoiding them, but growing the current, running disk just seems eerie to me every time I want to do it. Apparently I’m old.

There’s a new breakthrough technology available as a Technology Preview in SUSE Linux Enterprise Server 11 Service Pack3 (SP3). It’s called “virtio-blk-data-plane”—and you’ve probably never heard of it. But it deserves a fanfare because it gives KVM the ability to handle unprecedented storage I/O rates more than 50% higher than its competition. This is important …
