libtls shouldn't be a problem since month. just
apt-get install libc6-xen

also smp works really fine.

the console issue is nothing special, as xen domU's can use different kinds of
tty by design.
Which one to use is up to the admin, nevermind which default is used.

hwclock issue should be bugreported to the upstream maintainer as this could be
easily fixed.

your current problem is NOT the ID. This is caused by mac-address assigning
of the domU.
I bet, you didn't give a mac address in the domU config like
vif = [ 'mac=00:16:3e:de:ad:be, bridge=xenbr0' ]
so everytime the domU is booting it detects a new eth device, thinking that
the former one might come back.

sorry, never faced any problem with smp or filesystems on raid. are you talking
of a softraid? never tried this, but you should use your md0 as a pv for a lvm.
