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 All, The interface manual says - grant tables provide a generic mechanism sharing between domains. Subsequent lines suggest mechanism sharing between only unpriviliged domains. Can grant tables be used for this capability based shared memory communication between dom0 and domUs?

Hi All, I found it very difficult to get Xen-3.1 up on a a machine with Intel''s ICH9 family of disk controllers :-(. Is the ICH9 support really there in xen-3.2 ? I tried but was not successful in booting even xen-3.2 from xen.org. Did anyone have a success? Or any help on what extra config options I need to pass while compiling a domain0 from xen sources? Thanks, -- Pradeep Singh

HI Rusty, I wanted to play with lguest. As it was recently merge upstream by Linus, i took a look and the location looks like driver/lguest*. Unfortunately my local git repo cannot get the 2.6.23-rc2 changes from upstream somehow :-/.[duh... says "Cannot get the repository state from http://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git"]. i do not know what i am doing

Hello, my server has massive problems with my NIC. I got: "Detected Tx Unit Hang". At the moment I use 2.6.31 from Jeremy, does anyone know if it''s fixed in 2.6.32 or newer tree?

Hello. log of the crashing boot process: http://pasik.reaktio.net/xen/pv_ops-dom0-debug/pv_ops-dom0-bootlog-14-xen331-linux-2.6.29-rc6-crash.txt 2.6.29-rc5 based pv_ops dom0 works on the same computer.. with the same Xen version. I tried with and without pci=nomsi. adding ''noapic'' doesn''t seem to help (I need that with 2.6.29-rc5 to make it work). Any ideas

Hi Konrad I encountered a bug when trying to bring offline a cpu then online it again in HVM. As I''m not very familiar with HVM stuffs I cannot come up with a quick fix. The HVM DomU is configured with 4 vcpus. After booting into command prompt, I do following operations. # echo 0 > /sys/devices/system/cpu/cpu3/online # echo 1 > /sys/devices/system/cpu/cpu3/online With

These two patches were originally part of the XSM series that I have posted, and remain prerequisites for that series. However, they are independent of the XSM changes and are a useful simplification regardless of the use of XSM. The Acked-bys on these patches were provided before rebasing them over the copyback changes in 26268:1b72138bddda, which had minor conflicts that I resolved. [PATCH

Hi Ingo, Here''s the chunk of patches to add Xen Dom0 support (it''s probably worth creating a new xen/dom0 topic branch for it). A dom0 Xen domain is basically the same as a normal domU domain, but it has extra privileges to directly access hardware. There are two issues to deal with: - translating to and from the domain''s pseudo-physical addresses and real machine

paging mechanism clarification Hi All, The Xen uses 2 level Paging Mechanism to resolve the Virtual Addresses into frame numbers from domU.The first level is taken care by the MMU for the domU i.e translation from virtual address to the physical address just like normal paging mechanism. The second level of translation is done by the Xen hypervisor.It translates the pseduo physical address

hello, I would like to map (Read/Write) pages owned by a HVM guest from my Dom0 Linux kernel module. I have access to the "machine frame numbers" of these pages. 1. What is the right interface to do this? kmap needs ''struct page'' ptrs which I doubt exist for pages owned by a HVM guest. Is there a hypercall to do this then? 2. Do I need to modify the HVM behavior in

Hello, I am trying to boot a FC6 domU on Xen 3.2 (compiled on a FC6 system). After compiling Xen 3.2 successfully on FC6 and making the ramdisk, I modified the conf.grub as shown below. With this, I was able to boot xen. ------------------------------ --------------------------------------------------------------------------------- # grub.conf generated by anaconda # # Note that you do not have

''cat /proc/interrupts'' in a Linux PV domain shows interrupts starting at 256 and labelled as ''Dynamic-irq''. Are these available in a HVM domain, eg under Windows?

I am currently looking at a bug report[1] which is happening when a Xen PVM guest with multiple VCPUs is running a high IO database load (a test script is available in the bug report). In experimenting it seems that this happens (or is getting more likely) when the number of VCPUs is 8 or higher (though I have not tried 6, only 2 and 4), having autogroup enabled seems to make it more likely, too

I want to know any difference between writing, reading and shadow page table (for example performance). I am thankful for any help or resource for that. -- Best Regards Mohamad Taghi Mir Mohamad Rezaie Iran University of Science and Technology Department of Computer Science & Engineering System Software Group _______________________________________________ Xen-devel mailing list
