how to create 2 HDD on KVM for linux

asterisk14

i'm installing a linux program that expects 2 HDD's. One for linux program and other for storage. I've used Gpart to create 4 partitions (there were already 3 created by the linux), but the extra one does not show up. I think the program is expecting a physically separate HDD. Is there any way to emulate or do this in KVM?

You need to ask your host to split your hard drive.

Will the second HDD be used for a lot of IO? If not, you can try cheating by creating a loop device and mounting it.

@rds100 - second hard disk is just storage mostly, some log files, mostly static. how would i go about doing what you have said?

create 1GB empty image file

dd if=/dev/zero of=disk2.img bs=1M count=1k

setup loopback device

losetup /dev/loop0 ./disk2.img

create file system

mkfs.ext4 /dev/loop0

create mount directory

mkdir /otherdisk

mount the image

mount /dev/loop0 /otherdisk
