I'm not following all of what is on the machine here, but here are some
general things to try:
1. From what I can tell, your grub.conf expects /boot to be on its own
partition, which appears to be sda1 .. is that the case?
2. Verify your /etc/fstab looks right for the new virtual HW you set up.
3. If that is correct, try using "grub-install /dev/sda" to reinstall
your bootloader.
4. You might trying using the older/compatible versions of hardware,
specifically the SCSI controller in case that is an issue.
5. In the event that it really can't find /proc or /sys mount in a
chrooted rescue environment run "mkdir /proc /sys ; chmod 555 /proc ;
chmod 755 /sys"
Good luck!
