Hi, I''d be very interested to hear: does anyone have a stable working amd64 machine (in 64bit mode)? if so, which kernel do you use, and which version of xen / hg tree do you use? linux-2.6-xen.hg compiles fine over here, but reboots during boot. so fast I can''t see anything. (sorry, my laptop has no serial port. so I can''t capture a log file.) 2.6.16-rc4-git8 plus

Hello, I?m quite new to this list. I have a high frequency-dataset with more than 500.000 records. I want to edit a data.frame "Test". My small programm runs fine with a small part of the dataset (just 100 records), but it is very slow with a huge dataset. Of course it get?s slower with more records, but when I change just the size of the frame and keep the number of edited records

Hello All, As I promised, I've completed and initial patch for openssh PKCS#11 support. The same framework is used also by openvpn. I want to help everyone who assisted during development. This patch is based on the X.509 patch from http://roumenpetrov.info/openssh/ written by Rumen Petrov, supporting PKCS#11 without X.509 looks like a bad idea. *So the first question is: What is the

Hi, are there any patches for getting linux kernel 2.6.16.* working with xen 3.0.2. A friend told me .1 works fine, and .5 does not work at all, but maybe that information is outdated? Also there seem to be a number of security issues (2.6.16.9 was released today), so it would be nice if we could use the latest stable kernel with these fixes. are there patches to fix any problem with xen

a bit unrelated, still I wonder: does syslinux contain an mbr? or does anyone know any app that contains an mbr and can install it, without overwriting the partition table? my experience is, that is wise to have an mbr and use the active flag to select the active partition (which might have a bootmanager installed). however every linux distribution I know installed the bootloader such as

...high speed communication between the virtual machines, and the option to filter all traffic between them (without using the bridge netfilter tables) would be nice. Or is there a reason not to use such a setup, and a better option to implement this? Thanks for your help and best regards, Andreas Jellinghaus

Hi, I hope this is the right list for initramfs questions. First I noticed: with initrd I can use real-root-device and pivot_root mechanisms. with initramfs only pivot_root works. My init (or linuxrc) scripts end like this: mount -t xfs -n -o ro /dev/mapper/root /new-root umount -n /sys || true umount -n /dev || true umount -n /proc || true cd /new-root pivot_root . initrd exec chroot .

Hi, please correct me if I'm wrong: - the kernel needs enough ram for the compressed initramfs and the same files decompressed, so it can decompress the files and boot the /init on the initramfs. - if the kernel does not have enough ram, it will kernel panic. my tests were done on a server with 256 mb ram and a 80MB compressed initrd. I removed some packages and now it fits and the

Hi, Here's a try at writing an initramfs HOWTO. This is basically a write-up of a number of interesting emails I collected over time. It could probably use an editor, more fact-checking and a bunch of other good things, but it should be better than nothing ;-) Daniel -------------- next part -------------- INITRAMFS HOWTO 0) What are klibc and initramfs?

I''m using kubuntu dapper, so /proc/sys/kernel/hotplug is disabled, and instead udevd is running to get events from kernel and do what is necessary. in my first steps with xen (unstable), I get this error: root@nandemonai:~# xm create myxm Using config file "/etc/xen/myxm". Error: Device 2049 (vbd) could not be connected. Hotplug scripts not working. root@nandemonai:~#

Hi, xend start should test for /var/run/xenstored before running xenstored. on (k)ubuntu at least /var/run is a tmpfs, so after each reboot it is empty and you need to re-create all directories. a simple test -e ... || mkdir ... would prevent people from running into problems. maybe this is simple enought to get into xen-unstable before 3.0.2? Thanks, Andreas

till last week everything was fine, our cds with isolinux and created with mklinux worked fine. but suddenly our build system fails, the cds don't boot anymore, or more precisely: they do boot in vmware and on several new machines we have, but on lots of other, older machines they suddenly stopped working. we didn't change our scripts, and syslinux and mkisofs is still the same version

Hi, the latest kernel supports swap files, so I guess the resume code also works with those. So I wonder: is this still a good idea with ext3? As far as I know there is no such thing as a "mount read-only" with journalling filesystems - ext3 when mounted will always detect that it is not clean and replay the journal etc. So what do you think? Is it ok to use ext3 with swap files and
