Re: [Xen-users] Re: Xen 3.4 Hackery on Ubuntu 9.04 (aka Jaunty) Server

Christian,

I know how to explain clear.

The first install Xen on Ubuntu 9.04 aka Jaunty Server is supposed to create only :-
# cd /usr/local/lib/python2.6/dist-packages/xen
# ls -l
total 36
-rw-r--r-- 1 root staff 2 2009-05-20 17:03 __init__.py
-rw-r--r-- 1 root staff 140 2009-05-20 17:20 __init__.pyc
drwxr-sr-x 2 root staff 4096 2009-05-20 17:20 lowlevel
drwxr-sr-x 2 root staff 4096 2009-05-20 17:20 sv
drwxr-sr-x 3 root staff 4096 2009-05-20 17:20 util
drwxr-sr-x 2 root staff 4096 2009-05-20 17:20 web
drwxr-sr-x 5 root staff 4096 2009-05-20 17:20 xend
drwxr-sr-x 3 root staff 4096 2009-05-20 17:20 xm
drwxr-sr-x 2 root staff 4096 2009-05-20 17:20 xsview

By running
# make uninstall
you remove everything , but packages above.
It's a hack.

Real Xen 3.4 build should be done on another Ubuntu 8.10 aka Intrepid Server.
Servers may dual boot or to be on the same LAN:-

# cd /usr/src
# hg clone http://xenbits.xensource.com/xen-3.4-testing.hg
# cd xen-3.4-testing.hg
# make world
# make dist

Make dist is like "make install" on ./dist folder.
It's supposed to transfer Xen System to another Host.
It's root FS has to be mounted at Intrepid Server as
a directory.  Say /mnt.  Then remote install :-

# cd /usr/src/xen-3.4-testing.hg/dist
# ./install.sh  /mnt

It should report to you:-
Installing Xen from './install' to '/mnt'...
- installing for udev-based system
- modifying permissions
All done.
Checking to see whether prerequisite tools are installed...
Xen CHECK-INSTALL Wed May 20 14:33:35 EDT 2009
Checking check_brctl: OK
Checking check_crypto_lib: OK
Checking check_curl: unused, OK
Checking check_iproute: OK
Checking check_python: OK
Checking check_python_xml: OK
Checking check_udev: OK
Checking check_xml2: unused, OK
Checking check_zlib_lib: OK
All done.

This step will install working Xen System on remote  (or dual booting)
Ubuntu Jaunty Server.
More over it works without "fake install", but no "pygrub" in service.
   That's said. Fake install was done only to bring back to life "pygrub"
been transfered from Intrepid, because it silently invokes python 2.6 after
transfer. Don't forget to install python2.5 and python2.5-dev on
Ubuntu Jaunty Server before Xen transfer.

Thanks.
Boris.

I'm not saying that the uninstall script does anything wrong nor that you shouldn't use.
All I wanted to express is that you should be more careful when telling people to run a command that will actually delete more than they would anticipate from what you were saying...


Best regards,
