Shouldn't be a problem. The only issue would be whether the installed
OS has a driver for the emulated scsi drive.
Do you mean if the host OS has a driver ie F25?
No, the RH 5.2 OS. See below.
If you used the emulated
IDE instead, you would need to mount the image (or drive) locally and
edit the fstab to change the /dev/sd* entries to /dev/hd*.
Not sure why I would need to be emulating IDE . .
In case the emulated SCSI chipset isn't supported by the installed OS.
See below.
OK, I am still at a loss as to how to proceed . . I had assumed that I
would need to do a dd of the old SCSI drive with it's 6 partitions and
create an image that I could move to my F25 workstation and from there
work out how to load into virt-manager or something . .
Tom explained briefly, but I'll add some more details.
Yes, you should dd the entire drive to a file in
/var/lib/libvirt/images/. Then in virt-manager, create a new VM using
the "Import existing disk image" option and choose the file that you
copied the drive to. When you get to step 4, check the customize
button. In the list of VM parts, there will most likely be an "IDE Disk
1" or something similar. Click on it and open the advanced options
section. With a recent Linux version, you would ideally use the virtio
disk bus, but there wouldn't be support for that in RH5.2. The way it
works is that the VM provides a virtual disk controller for the OS to
use. But the OS has to have a driver for whichever chipset is being
emulated. Virtio skips all that by providing direct access to the
hypervisor and skipping all the emulation slowdown. I thought there
were different chipset emulations you could choose, but it looks like
from virt-manager, it only provides one for each bus type. Try the SCSI
bus and hopefully it will be supported. It likely will be as the
emulated devices tend to be commonly used chipsets.
Hopefully this helps you.
