Interrupt levels
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:

PSE in guests
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?

Serious performance issues
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:

ntpdate issues?
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:

I/O descriptor ring size bottleneck?
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

xen-testing and redhat-cluster devel
Hi,
I''m using xen on two-node redhat cluster (CVS devel version), using lvm
as storage backend.
redhat cluster is used to synchronize LVM metadata (using clvmd) and as
storage
for domain configs and dom-U kernels (with gfs).
Latest version of redhat cluster works with xen-2.0.4, but not with
xen-2.0-testing.
ccsd failed to start on 2.0-testing. Anyone knows what the problem is?

fdisk hard drive image
Hello list,
Currently, i use a partition image to run my XenU (/dev/hda2) and "fdisk

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.

Calculating real cpu usage of Xen domains correctly!
Hi all,
With the new vm-tools we are trying to get top like capabilities going
correctly. Currently we have a program vm-list that has some of this
capability but is dependent on the cpu time given by libxc calls
(xc_get_dom_info & xc_domain_get_cpu_usage). These two functions give
you how much time (in nanoseconds, why is this not documented) the
domain has been actively used. Approaches:

X problem (radeon/intel-agp) on unstable
Hi,
since 2.0.4 didn''t work with my notebook (see ''[Xen-devel] "general

xen-testing. Now I''m on xen-unstable but I still get the following problem.

hardware-watchdog driver problems in linux 2.6.10-xen0
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

[patch] final header fixes
I think this is the last of the header fixes I''ve run across. Though it''s
sometimes difficult to tell, I believe Xen/ia64 has asm/mm.h, flushtlb.h,
page.h, and shadow.h. Please apply.

New to Xen: Can Xen Work with OpenMosix?
Apologies if this is the wrong place to post this question. In that event,
please point me in the right direction.
My question is whether or not I can use Xen with OpenMosix. The upshot of what
I''m attempting to do is this:
1. Build a two to four node cluster using OpenMosix for "raw horsepower"
2. Use Xen on the OpenMosix cluster to divide the "raw horsepower" any

Newbie problem: disk error launching FC3 in non-0 domain
Hi again
I have a minimal Fedora Core 3 image running fine as domain 0 (thanks
and sorry for the previous FAQ query) using both the standard install
ramdisk image, and the FC3 ramdisk image downloaded from xen sourceforge.
However, I can''t get it running in a non-zero domain.
In brief, I have a full FC3 installed on /dev/hda1, which I typically
use as my domain 0 OS. Then I have a

Framebuffer (was Xen port of ReactOS)
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
