[Xen-users] Which variables should be set in hypervisor using first time
When I download the Xen 3.4.2 (hypervisor and tools) official source distribution http://www.xen.org/products/xen_source.html the XEN and did a make world it asked me a lot of choices like the below ones how should I choose and which ones to use I am not clear on this part apart from selecting configuration for my PC what should I use as modules If I am not wrong these are the same choices which would come when some one compiles a kernel from jeremy tree from soucre is there any standard documentation available for reading this choice[1-22]: 6 Generic x86 support (X86_GENERIC) [Y/n/?] y Maximum number of CPUs (2-255) (NR_CPUS) [32] 32 Preemption Model 1.

RE: [Xen-users] Which variables should be set in hypervisor using first time
I also met such a problem. As I mentioned in another thread "[Xen-users] difference between Xen and Dom0 kernel", the configuration of xen''s installation is really confusing. If no existing .config given, the makefile will create one with create_config.sh script and then make changes based on it. The following choices that Tapas are just the changes it will make to the config file generated by create_config.sh. If we want to use an existing config file, e.g., ubuntu''s default config (like /boot/config-2.6.27-xxx), these choices would be much more. Would anybody direct me to a subset of choices that are the most important for Xen''s installation? At the same time I''ll also try the config options given by http://wiki.xensource.com/xenwiki/XenParavirtOps. Thank you very much!

Re: [Xen-users] Which variables should be set in hypervisor using first time
Even I am also stuck up in this process can you tell the steps you did to compile the kernel. In a previous thread I mentioned about a book A hands on guide to the art of virtualization Jeanna Mathews but even this does not specifies exactly the parameters we are looking for.
