[Xen-devel] Xen-4.1-unstable hypervisor booting error
Hi, I''ve installed latest PVops kernel 2.6.32.21 (upgraded from 2.6.32.15 using the very same kernel build configuration - i.e. copied the config-2.6.32.15 file to the kernel source directory) and I can boot without hypervisor (using the standard kernel/initrd directives in grub) but not with the hypervisor since it fails.

Re: [Xen-devel] Xen-4.1-unstable hypervisor booting error
Could you try:-
/boot/xen.gz dom0_mem=1024M
. . . . . . . . . . .
Boris.
P.S. I had the same issue.

Hi,
I''ve installed latest PVops kernel 2.6.32.21 (upgraded from 2.6.32.15
using the very same kernel build configuration - i.e. copied the
config-2.6.32.15 file to the kernel source directory) and I can boot without
hypervisor (using the standard kernel/initrd directives in grub) but not with
the hypervisor since it fails.
Call trace is:

And the host is stuck and can''t boot.
Was it OK to use the config from 2.6.32.15 for 2.6.32.21 build or any pointers
what may be going on? The kernel/system is x86_64 system running on RHEL-5 with
the PVops kernel now but as I said, it can''t boot with the hypervisor
but everything is fine (except Xen) when booting without the hypervisor.
Thanks,
Michal

Re: [Xen-devel] Xen-4.1-unstable hypervisor booting error
Thanks a lot Boris, adding dom0_mem setting to 1G (1024M respectively) made it working fine so I guess there''s a wrong default setting for dom0_mem, at least for x86_64 architecture.
