Hi,

We have converted a very old fedora 5 server to run on oVirt. However, since the Fedora 5 does not have virtio drivers, or virtio-scsi drivers, the disks are connected to virtual IDE interface. The problem here is on a single IDE interface, we cannot connect more than 2 disks. But the old converted server had 4 disks on 2 IDE controllers.

First question is can we add one more virtual IDE Controller to the VM? If yes, please share the procedure. Or whether any one can share the proper virtio or virtio scsi for fedora 5 OS drivers so that we can get other two inactive disks working.

You might manage to write a vdsm hook to do this, no idea how hard this can be. See e.g.: https://www.ovirt.org/develop/developer-guide/vdsm/hooks-catalogue/ https://www.ovirt.org/develop/developer-guide/vdsm/hook/vmdisk/ Latter adds a virtio disk, you might try to write something based on it.

...

Unfortunately we cannot upgrade from Fedora 5 at the moment.

Neither are possible. Does the Fedora have an iSCSI initiator support perhaps? You can expose those disk via different VMs to that VM - but still it might look different to the OS. (We don't even support such an old OS - but if it works, great).

You might try to use a newer kernel. It seems like Fedora 9 or 10 started supporting virtio, so you can try their kernel. No idea if it will work, and what might break. Try first on a test VM.

Y.

Await your inputs.

Re: [ovirt-users] oVirt virtio drivers for fedora 5

Maybe you can make this two disks larger, make more extended partitions on them and move partitions from disks 3 and 4 to this two and modify fstab accordingly? Or if you don't need separate mount points you can extend space on / and move data to / filesystem tree and remove fstab entries, and use only 1 virtual disk, if it's acceptable. All this can be done from modern OS, you can connect all 4 disks via virtio drivers, connect 5th disk, move data to it, install fedora5 bootloader, modify fstab and than reattach to original vm via IDE.
