Which VM has Virtual SCSI Disks


I've been looking a VM SW, VBox and Qemu, and I'm looking to emulate scsi disks for an install, not ide. Anyone know which program will let me emulate scsi disks?

I don't know about VirtualBox or Qemu but VMWare does.

Any non-proprietary VM SW that has scsi emulation?

Thumbs up [SOLVED] QEMU Virtual LTSP install with SCSI disks

[SOLVED] Using QEMU (apt-get install qemu).

4 SCSI Disks: sd[abd]=9.1GB, sdc=18.2GB

RAID10+LVM+EXT4 Partitioning plan:

Quote:
* Active RAID partitions: sd[abd]
* Spare RAID partitions: sdc

* sd[abd]=9.1 GB
o P [1] 100 MB RAID type FD (boot)
o L [5] 450 MB RAID type FD (swap)
o L [6] 8.6 GB RAID type FD (os)

* sdc=18.2 GB
o P [1] 100 MB RAID type FD (boot)
o L [5] 450 MB RAID type FD (swap)
o L [6] 8.6 GB RAID type FD (os)
o L [7] 9.1 GB EXT4 type 83 (extra)

* md0 RAID10+VG-LV
o [3] md0-active=sd[abd]1
o [1] md0-spares=sdc1
o vg=lts-boot
o lv=lts-boot-lv
o Format type ext4 and mount as /boot

* md1 RAID10+VG-LV
o [3] md1-active=sd[abd]5
o [1] md1-spares=sdc5
o vg=lts-swap
o lv=lts-swap-lv
o Format type swap

* md2 RAID10+VG-LV
o [3] md2-active=sd[abd]6
o [1] md2-spares=sdc6
o vg=lts-os
o lv=lts-os-lv
o Format type ext4 and mount as /
Create disk images of type qcow2:
Code:
qemu-img create -f qcow2 sda_9r1GB.qcow2 9.1G
qemu-img create -f qcow2 sdb_9r1GB.qcow2 9.1G
qemu-img create -f qcow2 sdc_18r2GB.qcow2 18.2G
qemu-img create -f qcow2 sdd_9r1GB.qcow2 9.1G
Using ~/Downloads/xubuntu-10.04-alternate-i386.iso as cdrom:
Code:
qemu -m 256 -drive file=sda_9r1GB.qcow2,if=scsi,bus=0,unit=0 -drive file=sdb_9r1GB.qcow2,if=scsi,bus=0,unit=3 -drive file=sdc_18r2GB.qcow2,if=scsi,bus=0,unit=4 -drive file=sdd_9r1GB.qcow2,if=scsi,bus=0,unit=5 -boot d -cdrom ~/Downloads/xubuntu-10.04-alternate-i386.iso -soundhw ac97 -net nic -net user
F4 Modes: "Install an LTSP Server"

Eventually getting into the manual partitioning plan of RAID type FD:
With 100 MB for /boot, 450 MB for swap and 8.6 GB for os / on each disk.
