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.

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:

autotoolizing xen?
Hi there! I was wondering what the general opinion on autotoolizing xen is? I am volunteering to do so, if there is interest in updating the build system to use autoconf, automake and/or libtool. Is one configure script for all of xen enough or do you want to be able to configure all/some tools separately? I know that Anthony is no fan of libtool... are there more reservations about some

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? I

VFS: Unable to mount root fs on unknown-block(1,0)

UDP port 1194 marking/routing problem

I use such commands: iptables -t mangle -D POSTROUTING -o eth0 -p udp --dport 1194 -j MARK --set-mark 0x990 ip rule add fwmark 0x990

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: [nic@shell:~]

[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. Signed-off-by: Hollis Blanchard <hollisb@us.ibm.com> -- Hollis Blanchard IBM Linux Technology Center

Xen "restarting system" on Fedora FC4
I posted this to the Fedora-test list but I''ll try here. If I need to ditch fedora rpms and move to building directly from src before posting here, please let me know and I''ll do so (apologies in advance if this is the case). I have the following Fedora RPMS installed: kernel-xen0-2.6.10-1.1155_FC4 kernel-xenU-2.6.10-1.1155_FC4 xen-2-20050222 I can

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

hdX: lost interrupt?
I successfully installed Xen 2.0.4 from source on a Slackware 10 system. I installed grub, got that working and all. But when I boot the dom0 kernel, I get: cmd 0x5a timed out hdc: lost interrupt My hdc is my dvd burner... when I applied a kernel option of "hdc=ide-scsi" it seemed to have skipped over it but recieved the same error on hdd ...

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

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?

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?

Invalid or unsupported executable format, or is it a reiserfs problem?
Our newly build xen kernel does not boot. The error message is : Invalid or unsupported executable format.
