VMs with scsi don't start anymore

[crazy-to-bike]

As workaround,you can you boot from an ide disk (or floppy , then mount root on a scsi disk.

That's too inconvenient. But: Is using a virtual ide hd really slower than scsi?

Using a real hd ok, the scsi drive / bus has a higher data rate, but in a vm?

don't have really test scsi vs ide but they are many optimisations for scsi in qemu 1.0.


alternative method :

edit your vm config file, and add :

args: -option-rom 8xx_64.rom,bootindex=1


then download
http://www.lsi.com/downloads/Public/Host Bus Adapters/Host Bus Adapters Common Files/lsi_bios.zip

and extract 8xx_64.rom to /usr/share/kvm/


start your vm, it must boot

Thanks for the great tip spirit, works a charm!

Hello. I have the same problem with Proxmox 2.1 and I want to try this solution.
Any ideas where I can find the config file to put "args: -option-rom 8xx_64.rom,bootindex=1" in?

Thank you!
