Re: [PVE-User] Migration VM from VMWare 5 (.vmdk) to Proxmox

sata needs ahci driver.

set it to IDE which should be already included in the kernel.

Then change /dev/sda1 into /dev/hda1 in grub.

It will probably drop you into the rescue shell. Then change fstab too 
to point all the /dev/sdaX to /dev/hdaX


this will let you boot with an IDE disk.

Then if performance of the IDE is poor you could change to sata 
(changing back to /dev/sdaX) enabling ahci module in modprobe.conf and 
regenerating the initrd. (or even Virtio)
