Change the scheduler:

Q: I am experiencing a heavy slowdown of the entire dom0 and all other domUs if one domU gets under heavy load.Is there any way to tighten this domU by adjusting something like scheduling?
A: You can use elevator=cfq as the command line option for both the dom0 and domU kernels in grub.conf and /etc/xen domU config files respectively. This will force the use of cfq as the default scheduler. By default anticipatory is the scheduler in dom0 and noop in domU. Alternatively:echo "cfq" > /sys/block/sda/queue/scheduler

File for about:config in Firefox

I want to backup my about:config settings, where is the file that stores it?

I think you mean this file:

prefs.js

Look for it in

/home/your_user/.mozilla/firefox/orws2gsm.default

Settings for crash restore: 

user_pref("browser.sessionstore.resume_from_crash", false);

Comiple xen 3.3 on CenOS 5
Ref: http://www.nikhef.nl/pub/projects/grid/gridwiki/index.php/Xen_on_CentOS_5_-_Notes
1. download two tar files from xen.org
2. Install mercurial src code version manager

wget http://www.selenic.com/mercurial/release/mercurial-0.9.5.tar.gz
tar xvfz mercurial-0.9.5.tar.gz
cd mercurial*
make install
export PYTHONPATH=/usr/local/lib/python2.4/site-packages:${PYTHONPATH}
(if not export that environment variable, you will get an error as this: ImportError: No module named mercurial).

3. Install prerequested packages:


yum install \
gcc make zlib-devel zlib python-devel curses libncurses-devel ncurses-devel openssl openssl-devel \
`yum search xorg-x11|grep dev|grep x86_64|awk -F . '{print $1}'` \
bridge-utils tetex tetex-latex transfig libtool-ltdl dev86 glibc-devel


( for i386 version, replace x86_64 with i386)

4. tar xzf xen*, cd xen*, make world
5. cd dist, sh ./install.sh
6. disable tls:
Put this in /etc/ld.so.conf.d/xen.conf:

# This directive teaches ldconfig to search in nosegneg subdirectories
# and cache the DSOs there with extra bit 0 set in their hwcap match
# fields. In Xen guest kernels, the vDSO tells the dynamic linker to
# search in nosegneg subdirectories and to match this extra hwcap bit
# in the ld.so.cache file.
hwcap 0 nosegneg

Note that the file name _must_ end ".conf". When you've done that, run
/sbin/ldconfig and reboot. The problem should go away.

7. reboot
