RE: [Xen-users] Xen boot errors
Firstly thanks for the help thus far :)
With the addition of the Xen-specific options referenced (below) by Opensuse 11.2's kernel-xen additional options in the .config, more dialog occurs during the kernel compilation now.
I am fairly sure that the 'debug' releated options (relating to the network and pci backends) are not required to operate a stable XEN system. I was hoping to confirm that those options would just make error reporting more detailed (verbose) and not change the way XEN itself will operate?
-Will all the XEN features work without the debugging support compilied into the kernel?
-Also would someone like to weigh in as to how performance might be impacted by leaving these options enabled?
Any other XEN kernel configuration tips would be much apprecaited. Although I have not mentioned previously my system is x86_64 Debian Lenny. Hardware is an Intel Core i7 860, 8GB RAM, Intel VT-d and VT-d I/O enabled at the bios level.
Please correct me if I am incorrect with my assumption, thanks.

In the tar.gz source snapshot I downloaded there was a default x86_64 config at ./arch/x86/configs/x86_64_defconfig

No I did not put these lines in the config file, I did not see any CONFIG_XEN options in the default config so I thought that the xen-patchs might have enabled these options by default.
I will added these line to the current .config and recompile & test...
