Hello. I'm running CentOS 7 with mainline kernel 3.17 built by myself. I've configured the kernel with all the xen parameters as builtin instead of modules. Yesterday I've decided to try to build and install Xen from sources. I've pulled the latest sources from git, changed the branch to staging and built and installed xen like this: make xen make tools make stubdom sudo make

Hi. Im writing a kernel module to extract some information from kernel, the module is working really fine in an AMD (AMD Athlon(tm) 64 X2 Dual Core Processor 3800+), but, when trying to run the module in a i7 (Intel(R) Core(TM) i7 CPU 930 @ 2.80GHz) Im facing some strange errors (see below). The kernel versions are just the same on both machines (2.6.34.10-0.2-xen #1 SMP x86_64 x86_64 x86_64

I''m having an issue forwarding through an Intel on-board graphics adapter. This is on a Dell Optiplex 780 with 8GB of RAM. The pass-through works perfectly fine if I have 2GB of RAM assigned to the HVM domU. If I try to assign 3GB or 4GB of RAM, I get the following on the console: [ 41.222073] br0: port 2(vif1.0) entering forwarding state [ 41.269854] (cdrom_add_media_watch()

Hello, I am using Xen 4.0.0_21091_06-0.1 on OpenSuse 11.3 64 bit, with a Windows XP Pro SP3 32 bit guest, and my workstation keeping locking up, even the NumLock and CapsLock keys being unresponsive when it does. Where should I begin troubleshooting? Thanks, Todd CPU info: ___________________________________________________________________________ processor : 0 vendor_id : GenuineIntel

Good Afternoon. My colleague Stefan (sstan) was asked on the IRC channel to provide our use case for PV USB in our environment. This is possible with the current xm stack but not available with the xl stack. Currently we use PVUSB to attach a USB Smartcard reader through our dom0 (SLES 11 SP1) running on an HP Blade Server with the Token mounted on an internal USB Port to our domU CA server

Anyone can help me with this problem I''ve described here: https://bugzilla.novell.com/show_bug.cgi?id=612006 I''ve had XEN4.0 working on CentOS 5.4 platform without these problems.  I''m trying to do the same now with a newer laptop and CentOS didn''t recognise half hte drivers.  The latest opensuse 11.3 does have these drivers and specifically nouveau

I followed these steps to get 3.3 installed on a CentOS 5.2 machine: # wget http://bits.xensource.com/oss-xen/release/3.3.0/xen-3.3.0.tar.gz # tar xvcf xen-3.3.0.tar.gz # cd xen-3.3.0 # make tools # make xen # make install-tools # make install-xen Development deps were all meet, everything compiled w/o error. Used yum to install kernel-xen bridge-utils bridge-utils gtk-vnc (did I need that?)

This error is not 100% reproducible. However, kernel panic has been occurred many times for last two months. It usually happens when multi VMs (in our case, 14 VMs) are booting together. After we made three big changes to gain more availibility, it began to happen. Changes are : 1. Use *NAS* as vm storage for migration from local disk 2. Use *two bondings* for switch HA (with 4 nics) from

This dependence is undesirable and logically incorrect. It''s undesirable because Xen network protocol should not depend on a OS-specific constant. It''s incorrect because the ring slots required doesn''t correspond to the number of frags a SKB has (consider compound page frags). This patch removes this dependence by correctly counting the ring slots required.

Hello, Jeremy: See the included patch. If it''s OK it''d be nice to get it into xen/stable-2.6.32.x branch.
