I'm getting hda disks by default with kvm under RHEL5.4 using virt-install. This seems an odd default. Is there a reason for hda disks over sda disks? Can I change this?

These disks will show up in a RHEL5 guest as /dev/hda, etc. In newer distros, these disks show up as /dev/sda, etc. It's just a matter of the RHEL5 stack being older than the hdX -> sdX change. If you want to use scsi disks via virt-install, you can use: virt-install --disk ...,bus=scsi Though AIUI it's generally considered buggy at the qemu level, and may even be disabled in RHEL5.4 - Cole ^ permalink raw reply [flat|nested] 6+ messages in thread

Sorry, forgot about that. If you are installing a RHEL5.4 guest, use virt-install --disk ...,model=virtio or virt-install --os-variant virtio26 which will take care of disk and networking defaults. - Cole ^ permalink raw reply [flat|nested] 6+ messages in thread
