Re: [Xen-users] Help with system
Olá Gilberto,
Not going to help much ... just to give some feedback.
I never saw that error, and I just installed a CentOS 54 x86_64 on a
Quad AMD server (it installs xen 3.0.3, aka xen 3.1.2 or something)
but I do not remember to have that error. I'm now with xen 3.4.2, and
from xend.log I cannot see that BUG error.
The only think I notice different from what I'm used to see is your
kernel : I have 2.6.18-164.15.1.el5xen, you have
2.6.18-164.15.1.el5.*centos.plusxen*
I expect that if you install a from a CentOS repo you will get the same
kernel as me, but I'm wrong then.
Cheers,
N.

I do not know if this is a Xen Bug or CentOS or a Kernel BUG...
I use this kernel: 2.6.18-164.15.1.el5.centos.plusxen #1 SMP Wed Mar
17 20:32:20 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux
But doesn't matter what kernel I use come from CentOS mirror with xen
support...
I allways get that kernel message....
Somebody already have thi problem too???
Thanks for any advice...
