Hi James. I go through the patch, since all its changes happens inside __xen_evtchn_do_upcall(), so I apply the patch into my 2.6.31.kernel by manual. (I was failed to merge a usable, 2.6.38dom0, since quite a lot branch needed, such as blkback, netback) But still, the blue screen shows up. Log attached. Is the timeout better than before? Beside, I think I need find some to examine my

Hi, Creating a new domain is a lot easier in opensuse 11. I follow the instruction on the website and build a virtual machine which uses opensuse 11 as well (I installed it from iso image). Everything works fine except the network. I cannot access the Internet from DomU. Here is some information. P.S. the DomU id is 1. "brctl show" in Dom 0: bridge name bridge id STP

Hello, I''m currently trying to understand some problems I had in the past with mixing look-back with blktap(2) for HV and PV domains. I''m stuck reading the source code, so I''d like to get some help from the list. Interrupt me if I got something fundamentally wrong in my understanding so far: 1. With pure-HV the domU gets an emulated IDE (or whatever) disk. The

This patch contains fixes for persistent grants implementation v2: * handle == 0 is a valid handle, so initialize grants in blkback setting the handle to BLKBACK_INVALID_HANDLE instead of 0.

I''m running SLES10 SP1 and have been using file:/ for my file-backed domUs. The domUs sit on a shared OCFS2 SAN-backed filesystem and are run on my three or four XEN servers. I''m having issues with the loopback devices not being released when the domUs shutdown or migrate, so I decided to switch over to tap:aio for my file-backed domUs. This isn''t working, either.

Hi, I don''t see any obvious flush to disk taking place for vbd''s on the source host in XendCheckpoint.py before the domain is started on the new host. Is there a guarantee that all written data is on disk somewhere else or is something needed?

I accidentally realized today that any domU''s using the paravirt disk driver potentially suffer from poor performance when they get handed in a physical volume and partitioning is done inside the guest. The physical volume passed in has to be one that has the compat 512 logical sector size but hints its real sector size (eg. 4096) as physical sector size. In dom0 handling is correct and

Hey Jens, Please in your spare time (if there is such a thing at a conference) pull this branch: git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git stable/for-jens-3.10 for your v3.10 branch.

The xencommons runlevel script has a few modprobe calls to load drivers for dom0. Recently also the backend drivers for vbd and vif were added. Unfortunately without an explanation why that is (suddenly) needed. Now that I have been hitting such missing backend driver issue as well with a xenlinux based dom0 kernel I wonder how to handle the situation. The pvops kernel has 3 backend drivers

Hi Is it true that the GPLPV drivers is incompatible with QCOW images? The Windows DomU works fine with raw standard "file:/" images, and paravirtualized Linux DomU works fine with QCOW and raw images. If i use QCOW images with my Windows DomU''s i get a stop error: 0x00000007b (inaccessible boot device). It looks like the blkback.3.hda process, that normally starts with

Hi, One of our colleagues spotted a problem in xentop. Sometimes the VBD_WSECT value suddenly becomes unreasonably high, and it turned out xentop reads /sys/bus/xen-backend/devices/vbd-(domid)-(devID)/statistics/wr_sect into an unsigned long long. That value is exposed by blkback, and among other stat counters, it''s a signed integer: drivers/block/xen-blkback/common.h struct

Hi all, I want to install xen 4.2.1 on ubuntu 12.04. The default linux version is 3.0.29. After I install xen 4.2.1 and the system always reboot automatically. I can not enter the system. Now I have updated the linux kernel version 3.7.0. Download the linux kernel 3.7.0 and compile it, install it. The system can reboot successfully. However, I can not create the virtual machine successfully.

I have installed xen on a node and while starting up a guest while in the kernel boot I am experiencing a hold/pause. The kernel stops in the boot sequence still loading the kernel at: stdout ...
