Hi, since 2.0.4 didn''t work with my notebook (see ''[Xen-devel] "general protection faults" in dom0 when loading intel-agp module'') I tried xen-testing. Now I''m on xen-unstable but I still get the following problem. X loads but doesn''t display anything more than the X cursor. The rootwindow looks kind of strange. Please see

Hi! I''m trying to run w83627hf_wdt.ko watchdog driver in domain 0 (xenlinux 2.6.10-xen0), but the driver doesn''t seem to work (the machine reboots all the time after the watchdog-timeout set in BIOS). Is there something that could prevent the driver from accessing the watchdog-hardware (io-ports/registers) ? The watchdog-driver is very simple, and you can find it in

> OK, here is a patch which provides fine grained cpu utilization > reporting. Some notes: I really can''t see the point of this patch -- it isn''t necessary to log every scheduling operation to record CPU usage for a domain over multiple time scales. Simply exporting the cumulative CPU usage for all domains and polling it from dom0 will enable you to do this. If you do

Fwiw, I think a ReactOS port would be very useful to both projects. One thing I think xen could do with (if it isn''t there already) is some sort of virtual framebuffer like with disk and network. Dom0 could provide the backend of the virtual framebuffer (on virtual consoles or inside X windows or whatever), and the other domains could make use of the exported framebuffers. It

Hello list, Currently, i use a partition image to run my XenU (/dev/hda2) and "fdisk -l" return nothing and can''t open /dev/hda . I want to use a full hard drive image (not partition image) from my Xen0 as hda in my XenU. I want to be able to run fdisk on hda in my XenU to list and regenerate partitions. I tried with this (/img is my hard drive image): disk =

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I complained some time ago that a the dom0-kernel (2.6.9-based) inside Xen would wait forever when trying to detect the hard disks connected via the S-ATA controller, which is provided by the nForce 250Gb chipset. The problem guessed by Keir (IIRC) was that the interrupt routing didn''t work because Xen didn''t use ACPI to do

Hi everyone, I''m doing some networking experiments over high BDP topologies. Right now the configuration is quite simple -- two Xen boxes connected via a dummynet router. The dummynet router is set to limit bandwidth to 500Mbps and simulate an RTT of 80ms. I''m using the following sysctl values: net.ipv4.tcp_rmem = 4096 87380 4194304 net.ipv4.tcp_wmem = 4096

Looking at the 2.0 code, it looks like the guest OSs are made to believe that PSE is not available. Is this a design choice? Has any work been done on supporting 4M pages in guest kernels?

Hello, At first i want to thank you for your work on such a wonderful piece of software. If can get my setup running as planned it will help me to use my hardware ressources in a much more efficient way. I''m a xen newbie an trying to setup following environment: xen-2.0.4 compiled from source hardware: 2 PIV 3GHz Processors, 1GB RAM, 2 NICs Dom0: Debian Sarge kernel 2.6.10 on xen-br0

Hi. I spawned a thread last week about the failure of bridged networking and I have gotten a little further. Turns out that I _do_ have network connectivity from inside the domains, but I cannot get the network to come up when I boot. I have to login and start up the network manually. E.g. after installing Debian Sarge according to the debootstrap method outlined in the users manual, I created a

Hi. I have a Shuttle box with an AMD Athlon XP 2200+ and 1GB of RAM. I''m normally running it with Debian sarge/sid and kernel 2.6.10-1-k7, as built by Debian. I want to use Xen on it. I built a xen0 kernel which is as close to the Debian kernel as I can (no power management, no HPET timers, broken ISA drivers disabled), disabled /lib/tls, and booted with the new kernel. Everything works.

Hi *, i am coming from UML, and now i evaluate Xen on my desktop: Xen-2.0.4 linux-2.6.10 "CONFIG_MODULES is not set" "CONFIG_AGP is not set" "CONFIG_FB_RADEON=y" FC3, [/usr]/lib/tls moved away It works, but some desktop applications crash once in a while within dom0: metacity-2.8.6 firefox-1.0.1 wnck-applet (from gnome-panel-2.8.1) But

Hi, I''m trying to run ntpdate from domain zero and getting weird results. This used to work (prior to using xen). Is this related to xen at all or an entirely unrelated issue? Queries seem to work: # ntpdate -q time-b.nist.gov Looking for host time-b.nist.gov and service ntp host found : time-b.nist.gov server 129.6.15.29, stratum 1, offset 41.820087, delay 0.17027 17

I''m tracking performance on the machine I installed yesterday. mutt running on one Xen instance, accessing via imap to another instance, accessing via nfs the maildir in another instances, seems little laggy when moving up and down the message index list. Network latency seems low < 30ms on average. So I was tracking vmstat. On the mutt instances is seems reasonable: [nic@shell:~]

Given that dom0 is itself doesn''t managed the memory directly that you only need to compile HIGHMEM4G into the dom0 or domU kernels if you intend to use more than 1G in one domX instances. ie. Even if you have more than 1Gb of total physical memory, if none of the domX use more than 1Gb of memory, there is no need to compile in HIGHMEM4G. Or, does dom0 need to be compiled with this in
