Web-CVS-Tools is now under GNU GPLv3
Posted by Alex Amiryan in Code, Links on November 10th, 2009
Web-CVS-Tools is now release under GNU GPLv3. Project migrated to github.com, so now you can participate in development.
Web-CVS-Tools is a bunch of script written in Perl to automate and make easier web development using CVS. You can read about the intended web development team work flow in my earlier article, which can be found here.
To make some changes to source code just run:
git clone git://github.com/alexamiryan/Web-CVS-Tools.git

Have fun!
VirtualBox init.d service autostart script
Posted by Alex Amiryan in Code, howtos on November 4th, 2009
I’ve just installed started using VirtualBox on my Fedora 11 x86_64 and it works just perfectly. I’ve migrated from VMWare when it figured out that it is unable to work with latest kernel version. So I need to start some virtual machines in the background with system startup. I’ve made a lot of googling and found some dirty scripts that were not meeting my criterias. I’ve decided to write my own system startup service.
You need to create file named vbox in /etc/sysconfig/ to list the virtual machine names that you want to start with system. Also when shutting down this service will save state to all running VMs. Here is the script:
/etc/init.d/vbox
#!/bin/sh
#
# chkconfig: - 91 35
# description: Starts and stops vbox autostart VMs.
### BEGIN INIT INFO
# Provides: vbox
# Required-Start: $network $named $vboxdrv
# Required-Stop: $network $named
# Default-Start:
# Default-Stop: 0 1 2 3 4 5 6
# Short-Description: Autostart some Virtual Box VMs
# Description: Autostart some Virtual Box VMs that are mentioned in /etc/sysconfig/vbox file
### END INIT INFO
. /etc/rc.d/init.d/functions
MANAGE_CMD=VBoxManage
[ -r /etc/sysconfig/vbox ] && . /etc/sysconfig/vbox
prog=$"Virtual Box Machines"
start()
{
echo -n $"Starting $prog: "
RETVAL=0
for vbox_name in ${VBOX_AUTOSTART}
do
SERVS=1
echo -n "${vbox_name} "
daemon $MANAGE_CMD startvm "${vbox_name}" -type vrdp >/dev/null 2>&1
RETVAL=$?
[ "$RETVAL" -eq 0 ] || break
done
if [ -z "$SERVS" ]; then
echo -n "no virtual machines configured "
failure
RETVAL=6
else
if [ "$RETVAL" -eq 0 ]; then
success $"vbox startup"
touch /var/lock/subsys/vbox
else
failure $"vbox start"
fi
fi
echo
return "$RETVAL"
}
stop()
{
echo -n $"Shutting down $prog: "
for vbox_name in ${VBOX_AUTOSTART}
do
echo -n "${vbox_name} "
runuser root -c "$MANAGE_CMD -q controlvm "${vbox_name}" savestate" >/dev/null 2>&1
done
RETVAL=$?
[ "$RETVAL" -eq 0 ] && success $"vbox shutdown" || \
failure $"vbox shutdown"
echo
[ "$RETVAL" -eq 0 ] && rm -f /var/lock/subsys/vbox
return "$RETVAL"
}
status()
{
for vbox_name in ${VBOX_AUTOSTART}
do
echo -n "${vbox_name} "
$MANAGE_CMD showvminfo "${vbox_name}"|grep "^State:\s*.*$"
done
}
case "$1" in
start)
start
;;
stop)
stop
;;
restart|force-reload)
stop
start
;;
status)
status
;;
*)
echo "Usage: $SCRIPTNAME {start|stop|restart|force-reload|status}" >&2
exit 3
;;
esac
:
And here is configuration file:
/etc/sysconfig/vbox
# Virtual box machines to autostart # Example to start 2 machines # VBOX_AUTOSTART = "MachineName1 MachineName2" # VBOX_AUTOSTART=""
Thats it. If you have any questions do not hesitate to contact me.
