Hi there,

Actually, when i need an hypervisor, i use an RHEL 5.2 ou 5.3 distrib
xen version 3.0.3 "Red Hat" (with some backport, modification, etc...)

But i wanted to try the Xen 3.3, to do that, i used Suse / Opensuse distrib,
xen version 3.3

But, i have many trouble to use it and need little help and explanation :

- Now, i can''t create Para-virtualised host, if i try to create a 
para-virtualised VM with the RHEL Kernel (for exemple)
I have drivers issues, the VM can''t see hard-disk or DVD device... and 
crash if i use network install (Glibc detected blablabla)
Someone know why ???

- I don''t have VT, so, with the Xen 3.0.3, i have never been able to 
create Fully Virtualised host... no problem
Now, with the Xen 3.3, i can create Full Virtualised VM (VM works, but 
with bad performance)
?!?

- I''ve tried to import Xen Para-Virtualised VM from Xen 3.0.3 to Xen
3.3...
On my new Xen 3.3 hypervisor :
If i use the "Xm create" command, the 3.0.3 VM start, everything
fine...
If i use the virt-manager to import VM : "Unable to find Kernel" or 
"Device not found etc etc..." (With same config file)
?!? Again

Does someone can answer me, or tell me where i can find some help ???

Thanks Again
Tom

It''s actually 3.1.2 with lots of backports. Don''t trust the
rpm
version number :)

Using http://www.gitco.de/repo/ with RHEL 5.3 is easier, since you''re
already familiar with RHEL.

Dunno, sorry. Probably opensuse-specific bug.
I''ve been using RHEL 5.3 as both dom0 and domU with Xen 3.3.1 from
Gitco without problems, so you might want to try that.

Hardware vritualization support is still required for HVM/fully
virtualized guest, regardless of Xen version. Are you sure you don''t
have VT?

How do you "import" a VM using virt-manager?
AFAIK the way to "import" a domU from its config file is by running
"xm new" instead of "xm create". You''ll then be
able to see it on
virt-manager.

***************************************************
When install OpenSUSE 11.1 select XenHost package.
OpenSUSE 11.1 has vminstall GUI tool
with equivalent to virt-manager functionality.
Just get built in help for it, to manage
properly. It''s a bit different from RH''s
virt-manager.
Actually, in Suse 11.1 vminstall does
work and creates images loadable via
suse''s pygrub
