Install Xen 4.0

["plamen .." <paco078@abv.bg>]

 Hi all,

I'm trying to upgrade ubuntu 8.0.4 LTS to Xen 4.0 with kernel 2.6.32.12. I get kernel sources from kernel.org, compile and install them. Thus ubuntu boots OK with 2.6.32.12 and everything works. After that I got Xen 4.0 from git repository, build and install:

make xen
make tools
make stubdom
make install-xen
make install-tools PYTHON_PREFIX_ARG=
make install-stubdom

update-rc.d xend defaults 20 21
update-rc.d xendomains defaults 21 20

Replace Xen kernel in grub and after reboot kernel start booting and in about 2 seconds system halts and screen goes blank. It is not possible to see what is the actual error and last line before the screen goes blank.

I tried to install another way to 'make world' in the Xen 4.0.0 sources. They came with kernel 2.6.31.13 and had source checkout issues which I was needed to manually workaround. At the and the result was same - linux booting starts and 2 seconds later system halts with blank screen.

Do I miss something or Xen 4.0 is NOT compatible with those kernel versions ? 

Thanks in advance,
paco
