Thanks, but I still miss how to grow the partition inside the disk
inside the lvg (lvg -> /dev/xvda -> /dev/xvda1)
To summarize, the steps should be (from dom0):
1) grow the lvg used for domU (=/dev/xvda from the domU point of view)
-> lvextend -L +1024 /dev/vg_domU/lv_FC55
2) grow the partition used by "/" in the lvg (/dev/xvda1) with parted
-> parted /dev/mapper/vg_domU-lv_FC55
-> resize 1 32kB 9664MB (This does not work, see below)
3) resize the fs with resize2fs (from dom0) or with ext2online from domU
(thanks to Jeremy)
-> resize2fs /dev/mapper/vg_domU-lv_FC55
Here's the output from parted:
Using /dev/mapper/vg_domU-lv_FC55
(parted) print
Disk geometry for /dev/mapper/vg_domU-lv_FC55: 0kB - 9664MB
Disk label type: msdos
Number Start End Size Type File system Flags
1 32kB 8587MB 8587MB primary ext3 boot
(parted) resize 1
Start? [32kB]? 32kB
End? [8587MB]? 9660MB
Error: File system has an incompatible feature enabled.
Is there a tool other than parted I could use to resize the partition
/dev/xvda1 inside the lvg?

After that I'm stucked:
- I cant expand the filesystem for "/" from domU: "fdisk" gives the
correct (new) size for "/dev/xvda", but I can't use parted or
rezise2fs on "/dev/xvda1" as it is mounted...
Take a look at ext2online for online resizing of ext[23] filesystems
- Maybe, from dom0, a combination of "lomount" and "parted" or
"resize2fs" or other tools could do the job but I don't know how to do
it.
Take a look at kpartx (I think it's in the device-mapper-multipath
package for whatever reason, but that's neither here nor there) -- it'll
let you set up device mapper devices based on a partition table if you
want to do manipulation of guest filesystems from dom0
