Thanks Rick and Uriel.
It was seeing double because as Uriel pointed out the root had errors and
nothing was mounted.
I linked and mounted the mini disks on another guest and repaired it.
I have another guest that uses LVM and it gave FSCK errors (reiserfs). I
ran FSCK on the PV's and it made it worse. By the time I got to doing it
on the LV, the damage was alread done.
I then restored all the relevant volumes (luckily only 4) and brought up
the guest. It threw up reiserfs errors and ended in kernel error.

RECONNECTED AT 22:33:53 PDT SATURDAY 06/04/05
The /usr, /home, /var and /tmp are in LVM. I am thinking of 'borrowing'
/usr, /var etc from another guest, not mount the LVM's at boot up, repair
and return to original config.
Any suggestions?

Re: Linux guest seeing double root partitions!
What do you mean "df shows duplicate root partitions"?
Do you mean something like
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/hda2 632476 104088 496260 18% /
/dev/hda1 116648 5443 105183 5% /boot
/dev/hda5 1897420 594208 1206824 33% /var
/dev/hda2 632476 104088 496260 18% /
tmpfs 258348 16 258332 1% /dev/shm
/dev/hda6 3162420 1693484 1308288 57% /usr
/dev/hda7 3162420 636100 2365672 22% /opt
If so,
that is easily fixed.
The problem is simply that it is listed in /etc/mtab twice.
Quick way to fix it might be (no promises)
cat /dev/null > /etc/mtab
mount -f /
sync ; sync ; shutdown -r now
If you have network access
it would be better to use your favourite editor on /etc/mtab.
