The "root=" part is not valid; it's specifying nothing for the root
filesystem device. Your old menu.lst file probably the info you
need. There is a line somewhere in the file that starts with:
# kopt=...
That is where you put such options as the "root=" business that will
be present in every entry. update-grub reads that line and creates
the entries from it.
For example, one of my wheezy VMs has this:
# kopt=root=UUID=5658a3af-0344-4bc4-8ba6-4ca2cc6cf429 ro console=hvc0
The "root=" part should be the block device that has your root
filesystem on. Yours will be either /dev/xvda or /dev/xvda1. I
generally recommend using the UUID of the filesystem, that way if
the device name changes then things still work.
From the rescue VM you can see with
$ cat /proc/partitions
whether you have a partitioned disk or not (if there's an xvda1 it's
partitioned). But I can save you some time and tell you that you
don't. Therefore your root filesystem is on /dev/xvda.
You can tell the UUID using:
$ sudo tune2fs -l /dev/xvda | grep UUID
but I can save you some time and tell you:
Filesystem UUID: 8a67d497-9377-48b8-910e-b979c6f405e0
So your kopt line should be:
# kopt=root=UUID=8a67d497-9377-48b8-910e-b979c6f405e0 ro console=hvc0
Once you have edited that into the file
$ sudo update-grub.
I suspect it will then boot.
Cheers,
Andy
