I am attempting to use libvirtd/kvm on CentOS 5.latest to migrate a SCO
OpenServer 5.0.6a VM from the old VMware server.
I have converted the multiple vmdk disk files to a single file, then used
qemu-img convert to create files for libvirtd, both qcow2 and raw formats.
After many attempts to get this working I'm up against what appears to be a
+ The VMware VMs are using straight 'ide' HD emulation which has been
working well for several years.
+ The 'ide' on libvirtd appears to map to SATA which isn't supported by
OSR5. I've tried doing a fresh install from CDROM, but the
installation fails to find the hard disk. I might be able to find the
appropriate BTLD for this, but that won't help migrating existing VMs.
+ When I tried using 'scsi' libvirtd says this isn't supported. This
would be my preferred emulation as we have used SCSI drives since the
early days of Xenix on Tandy hardware.
+ The final problem if these are solved is that SCO is funny about its
drive geometry, and the current versions of libvirtd and qemu don't
appear to support the <geometry> allowing one to specify heads,
Am I going to have to resort to using VMware workstation for this?
