Hi all, Please can anybody explain how communication(direct or indirect) happens between xen and guest os(windows) in full virtualization mode. Both from VMM to guest and from guest to VMM. Thanks and regards, Aditya. __________________________________________________________ Yahoo! India Answers: Share what you know. Learn something new http://in.answers.yahoo.com/

Hi list, I''m using Dom0 gentoo with xen 3.0.4 and xenman. I have several DomU working and it is really nice :) so all my DomUs are installed with disk images. Now i want to use an ISO to boot and install a linux system (or win). When i try to boot the DomU i dont have nothing, nothing relevant (for me) in logs and i can connect to the console. The state of the DomU is unknow. Any help

If a domain has PCI devices then we can''t safely save or migrate it. At least one user has had system crashes due to this, and the way the xendomains script automatically saves and restores domains on reboot. Since there''s no sensible semantics for it at the moment, we should disallow it and return an appropriate error message to xm. The first attached patch prevents the

Hi, I''ve been trying to boot from a RHEL4 install iso without much luck (the xen way).

Hello, http://wiki.xensource.com/xenwiki/XenBusDriver?highlight=%28xenbus%29 says that "XenBus provides a bus abstraction for paravirtualized drivers to communicate between domains. In practice, the bus is used for configuration negotiation, leaving most data transfer to be done via page flipping." What is the equivalent mechanism for fully-virtualized drivers in Xen (HVM running

I''m using xen-unstable, and I''ve successfully made a passthrough of an intel storage controller to an HVM domU, binding with pciback. 00:1f.2 SATA controller: Intel Corporation 6 Series/C200 Series Chipset Family SATA AHCI Controller (rev 05) I can access the array from within Windows by installing Intel Rapide Storage Drivers, and everything works as it should. I only have a

I''m looking at doing something that may seem a little bit odd, I would like to use xen to virtualize several desktop environments, with a specific keystroke configured to switch to that environment. I will have either gentoo or debian as a dom0. this will be used only for management of the virtual machines. I will have several full desktop environments for different users. For example, I

Hello, I am a newbie at xen - I am trying to trace the complete execution of a trap. Specifically, I am trying to find out where the control transfer happens between a domU to dom0 when a trap occurs, and where the control switches back to domU after the trap is handled. I was wondering if there is some documentation on this or someone may be able to help me out. Thanks, Girish

Mats, Thanks for your trial; following your mail I tried it with hda; it is the same, it does not work - "fdisk -l" does not show hda.

What are methods to debug domU when it hangs? Using xen 3.1 compiled from sources I could not manage to launch no domU. Fot instance, I run something like this: =====8<===================== disk = [ ''file:/oradata-act/sles.disk,hda1,w'', '',hdc:cdrom,r'' ] kernel = "/boot/vmlinuz-2.6.18-xen" ramdisk = "/boot/initrd-2.6.18-xen" cpus =

Hi all, I''m brand new to Xen and this list. I''m planning on using Xen. Especialy I''m interested in the Live Migration Feature. Somewhere I read that the hardware must be identical. What does this mean? Will migration work from a P4 to a Xeon (Core2 Mircoarchitecure) ? Will migration work if they got different NIC? What are the limitations? Maybe someone does already

Keir, is there a particular reason you chose to use slightly different special mode numbers than Linux, ignoring VIDEO_CURRENT_MODE altogether? I think it wouldn''t be bad to be in sync with Linux here, and I independently think that having a way to avoid mode switching altogether is good to have in case of possible problems on exotic hardware.

Hello All, I have been having a very difficult time getting any template to work on xen.

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

I''ve now given up trying to get grub working with my particular e1000 adapter, I''ve tried all the patches and all I can get is something that works a little bit but never past the grub menu. I''m sure I read something somewhere about a tool which would combine a multiboot image + modules into a single bootable item which could be loaded by lilo, and am hoping that the

At the moment, we translate the virtual address from the guest in the page-fault-handler to guest physical address via the gva_to_gpa() function in svm.c/vmx.c:
