Hi, I implemented my own Hypercall in xen. Now I wish my application under dom0 could talk to Xen via my hypercall. Currently, I make a stub in dom0''s kernel, which works as a proxy to forward the request. So, my application first makes a system call to dom0, which then makes hypercall to xen. Is this design necessary? May I call hypercalls from user application under dom0 directly?

I was following an email chain in the xen mailing list on HVM hypercalls on grant tables and the email chain link is below http://lists.xensource.com/archives/html/xen-devel/2007-03/msg00688.html This link says that we need not required hypercalls to share memory b/w HVM''s. But as far as my understanding of sharing memory is concerned, I think the memory is shared using grant table

Hi I have a doubt regarding Mini-OS and Xen. If it is true that Xen reserves in the virtual address space the top 64MB on 32bit systems and 168MB in PAE systems, doesn''t it exist with a Mini-OS kernel which has only 32MB in size i.e. going by its default config file? Obviously I''m missing something. Regards, Bhaskar. _______________________________________________ Xen-devel

Hi, I''m trying to use the SYSCALL/SYSRET opcodes with a minios kernel without much success. Going by the manuals (and linux sources) I first have to setup the STAR and LSTAR registers to define the segment and instruction pointer to be used for SYSCALL: /* * LSTAR and STAR live in a bit strange symbiosis. * They both write to the same internal register. STAR allows

I am shame to say that I have never met a function whose return value is void*. This is the first time~~~ So, can anyone told me the meaning of the return value of this function -----xc_map_foreign_range? Is it a pointer pointed to a memory area corresponding the machine frame number(the last parameter passed to the function)? And the third parameter named size: the unit of size is in bytes or

Hi, I''d like to do some operation every time an hypercall is issued in a domU kernel. I started modifying include/asm-i386/mach-xen/asm/hypercall.h but I don''t think it''s such a great idea, so I think that, as a last chance, I''ll have to substitute all of the hypercall function call with some wrapper function of my own. Can anyone tell me if

Hi , Are there any options with xenstored to access xenstore ? Can I look up contents of xenstore ? Thanks, Sanket _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi all, I''ve taken a stab at documenting the current interface between netfront and netback drivers, here: http://wiki.xensource.com/xenwiki/XenNetFrontBackInterface Currently, the only way for non-Linux implementers to adhere to this interface is to study the Linux netfront driver, which has a great deal of optimizations and is not meant to be documentation. I''d love it if

Good morning, I am new to Xen, and trying to understand how Xen works. I have some questions about virtualization of interrupts on Xen. Thanks in advance for all helps. 1) From papers about Xen architecture found at Xen homepage, Xen seemingly intercepts interrupts of Dom1 (paravirtualization). So interrupts occur in Dom1''s context are sent to Xen, and Xen handles them. Is that correct?

Hi, I have a question about memory page tables in Xen. As far as I understood, every modification to page table will go through Xen(hypervisor). Is it so that all page tables are actually allocated in Xen(hypervisor) instead of guest OS(domain)? Also, is it the case that Xen(hypervisor) needs to maintain a page table for each process running in every domain? Thanks Haifeng

Hi, I need to use the grant table mechanism, but I can''t find any example regarding how to do it. Could you please provide some examples?

It seems to me that Xen is full of stuff that aren''t beneficial for everybody, this includes NUMA, ACM and other stuff that certain companies try to introduce... In a better world, the Xen binary would have been more sleek and fast, and those extra features should be loaded via stating a Module boot line in Grub. This way, testing would be easy and it''s more elegant than using a
