Q1:
virsh start --console "some-guest"
How can a different kernel be booted from?
If kernel=0 won't complete boot.
Q2:
On one Guest, cannot enter luks pw.
It shows where to enter it,
just no asterisks.
even though all console=tty*
is in last position on grub2 cmd line.

Maybe try sgabios? Add this to your guest's <os> block:
<bios useserial='yes'/>
Make sure sgabios is installed. You'll probably need to create a manual
symlink until this bug is fixed:

Not sure about that one.

Can I add this using virt-isntall? Can virt-install configure sgabios with
an option?
Is there any command line tool, which can add/remove/update XML parameters?
Example:
tool --add domain.os.bios useserial=yes

There's /usr/bin/xpath but that's for querying only it seems. Would be pretty
straightforward to make one for setting arbitrary data.
Though in this case I think finishing off virt-xml is the best way to go, I've
just never managed to give it the final push:

OK, I wrote one. Please look at this:
http://www.salstar.sk/pub/salpack/usr/sbin/virsh-pyquery
This script uses pyquery, jquery based selector syntax. If you like jquery
selectors, then you will like it. It can add/delete/remove/update entities
or attributes.

Nice too, but limited to only supported options. :(

Very cool! Something like that should be implemented as a virsh subcommand
(but it would likely use xpath syntax since that's what libvirt uses internally).

True, but support also comes with docs, --help discoverability, no need to
know the XML syntax, and future proofing against XML changes. That said there
is definitely a need for both tools.

OK, try to look at xpath version with some enhancements:
http://www.salstar.sk/pub/salpack/usr/sbin/virsh-xpath
It's still beta quality, but functional.
Example options:
# Query boot options:
--guest NAME --query //os/boot
# Add an element with attributes:
--guest NAME //os --add bios --attr useserial=yes
# Update attribute of an element:
--guest NAME //devices/disk/driver --update --attr cache=none
# Remove attributes:
--guest NAME //disk/driver --remove cache --remove type
# Delete element:
--guest NAME '//os/boot[@dev="hd"]' --delete
