[Gllug] Xen - bit of a ramble

[Adrian McMenamin]

Because I had the time and a spare box I tried to install xen at the
weekend. It did not go well.

Ubuntu failed because the stock binary didn't like LVM and I couldn't seem
to get a new initrd to work. I had the Fedora Core 5 isos downloaded so I
burn them and installed.

I had forgotten, of course, that Fedora installs SE Linux by default so
when I realised that appeared to be messing up by system I removed the
SELinux rpms whereupon I lost bash and much else besides so had to
reinstall the whole thing.

Got to that point and then discovered (this is now 1am this morning) that
the xen kernel yum offers is b0rked (see
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=190899) but at least
there is a promise of a fix.

But when I finally get that done, and get guest systems installed etc, how
do I access the virtual systems over ssh or similar? There isn't much
about this to be found anywhere.

http://ftp.hpl.hp.com/techreports/2004/HPL-2004-207R1.pdf suggests using
vnc but what about simple cli access? And how does networking work - can I
assume that the whole xen system is a bit like a NAT-in-a-box?

I know these are basic questions but I have been googling and it's not
clear to me.
