Bonjour a tous,
Toujours des problèmes avec XEN.
Avant tout, je suis sous SUSE 10.0 et j'ai installé le
pack de XEN qui est compris dans les cd de la
distribution.
Mon disque est un SATA
j'ai suivi la procédure décrite sur xenfr.org qui est
presque la meme que celle du site "officiel" de XEN.
J'ai donc decopié les fichiers d'installation dans un
"disque virtuel" que j'ai mis dans un répertoire
/stockage
Xen démarre bien et lorsque je lance xm create
/etc/xen/VM-Linux1, il me dit que le service est ok
mais, quand je demande la console, je vois qu'il y a
des erreurs.
==============================================
Voici la procedure que j'ai utilisé

A pair of credits:
Joshua Macdonald wrote the first draft of the
transaction manager. Yuri Rupasov
did testing and benchmarking, plus he invented the
r5 hash (also used by the
dcache code). Yura Rupasov, Anatoly Pinchuk, Igor
Krasheninnikov, Grigory
Zaigralin, Mikhail Gilula, Igor Zagorovsky,
Roman Pozlevich, Konstantin
Shvachko, and Joshua MacDonald are former contributors
to the project.
Lycos Europe (www.lycos-europe.com) had a support
contract with us that
consistently came in just when we would otherwise have
missed payroll, and that
they kept doubling every year. Much thanks to them.
