I assume this is just SCSI emulation, > like some older devices have used? There's several things going on here: (1) SATA (which is really IDE) uses the SCSI infrastructure in the Linux kernel. So disks appear as /dev/sdX. (2) Old kernels used a separate IDE infrastructure (/dev/hdX). But I'm pretty sure this is all deprecated now and even old PATA IDE disks will use the SCSI infrastructure and appear as /dev/sdX. (See also: http://linux-ata.org/) (3) In the virtual machine the situation is complicated: (a) If the virtual machine is fully virtualized, we emulate an old PATA disk controller, so the virtual disks appear as /dev/hdX. (b) If the virtual machine has either Xen paravirt drivers installed or is completely paravirtualized, Xen has its own block device infrastructure and the disks appear as /dev/xvdX. Virt-p2v attempts to rewrite /etc/fstab after migration so that drive names are rewritten correctly. If it doesn't get this right then you may need to boot the virtual machine in single user mode and edit /etc/fstab. (If you have to do this, let me know some details and the contents of /etc/fstab.p2vsaved and /etc/fstab because it's a bug). Situation (3)(a) above is slow. You can improve things for your Fedora Core 1 system by installing a Xen kernel from a later version of Fedora, although this is at the moment entering somewhat uncharted territory so keep a backup.
