[edit] How to install MS VirtualServer/MS VirtualPC Addons on Gentoo Linux

Download Virtual Machine Additions for linux from [1] and install it on VirtualServer/VirtualPC host.

Inside your Gentoo Linux guest machine install rpm2targz for convert rpm additions package.

Convert rpm additions package

Install packages

and build modules

Now you need to modify runscript for Gentoo

• Edit /etc/init.d/vmadd as follows.

#!/sbin/runscript 
# @file 
# Microsoft Virtual Machine Additions for Linux 
# Provides:       vmadd 
# Description:    VM additions kernel module 
 
kdir=/lib/modules/`uname -r` 
dev=/dev/vmadd 
modname=vmadd 
module=$kdir/misc/$modname 
prepapp=/usr/sbin/vmadd-prepare-module 
dll=/usr/sbin/vmadd.dll 
file="" 
test -f $module.o  && file=$module.o 
test -f $module.ko && file=$module.ko 

test -z "$file" && { 
   eerror "kernel module not found" 
   exit 1 
} 

running() { 
   lsmod | grep -q vmadd[^_-] 
} 

start() { 
       ebegin "Starting VM additions " 
       running || { 
               rm -f $dev || { 
               eerror "cannot remove $dev" 
               exit 1 
               } 

       modprobe $modname || { 
               eerror "modprobe $modname failed" 
               exit 1 
               } 
       } 

       if [ ! -c $dev ]; then 
       maj=`sed -n 's;\([0-9]\+\) VMAdditions;\1;p' /proc/devices` 
       test -z $maj && { 
               rmmod $modname 
               eerror "cannot locate device major" 
               exit 1 
       } 

       mknod $dev c $maj 0 || { 
               rmmod $modname 
               eerror "cannot create device $dev with major $maj" 
               exit 1 
       } 
       fi 
       test -x $prepapp && { 
       $prepapp $dll || { 
               rmmod $modname 
               eerror "cannot prepare module" 
               exit 1 
       } 
       } 
       return 0 
} 

stop() { 
       ebegin "Stopping VM additions " 
       if running; then 
               rmmod $modname || eerror "cannot unload module $modname" 
               rm -f $dev || eerror "cannot unlink $dev" 
       fi 
       return 0 
}

• Edit /etc/init.d/vmadd-heartbeat as follows.

#!/sbin/runscript 
# Microsoft Virtual Machine Additions for Linux 
# Provides:       vmadd-heartbeat 
# Required-Start: vmadd 
# Required-Stop:  vmadd 
# Description:    VM additions service heartbeat 

PIDFILE="/var/run/heartbeat" 

BINARY=/usr/sbin/vmadd-heartbeatd 

running() { 
   lsmod | grep -q vmadd[^_-] 
}  

depend() {
       vmadd
}

start() { 
       ebegin "Starting VM additions service heartbeat" 
       start-stop-daemon --start --exec $BINARY \ 
         --pidfile $PIDFILE 
       RETVAL=$? 
       test $RETVAL -eq 0 && touch $PIDFILE 
       eend $?
} 

stop() { 
       ebegin "Stopping VM additions service heartbeat" 
       start-stop-daemon --stop --exec $BINARY \ 
         pidfile $PIDFILE 
       eend $? 
}

• Edit /etc/init.d/vmadd-shutdown as follows.

#!/sbin/runscript 
# Microsoft Virtual Machine Additions for Linux 
# Provides:       vmadd-shutdown 
# Required-Start: vmadd 
# Required-Stop:  vmadd 
# Description:    VM additions service shutdown 
 
PIDFILE="/var/run/shutdown" 
BINARY=/usr/sbin/vmadd-shutdownd 

running() { 
   lsmod | grep -q vmadd[^_-] 
}  

depend() {
       vmadd
}

start() { 
       ebegin "Starting VM additions service shutdown" 
       start-stop-daemon --start --exec $BINARY \ 
         --pidfile $PIDFILE 
       RETVAL=$? 
       test $RETVAL -eq 0 && touch $PIDFILE 
       eend $? 
} 

stop() { 
       ebegin "Stopping VM additions service shutdown" 
       start-stop-daemon --stop --exec $BINARY \ 
         --pidfile $PIDFILE 
       eend $? 
} 

• Edit /etc/init.d/vmadd-timesync as follows.

#!/sbin/runscript 
# Microsoft Virtual Machine Additions for Linux 
# Provides:       vmadd-timesync 
# Required-Start: vmadd 
# Required-Stop:  vmadd 
# Description:    VM additions service timesync 
 
PIDFILE="/var/run/timesync" 
BINARY=/usr/sbin/vmadd-timesyncd 

running() { 
   lsmod | grep -q vmadd[^_-] 
} 

depend() {
       vmadd
}

start() { 
       ebegin "Starting VM additions service timesync " 
       start-stop-daemon --start --exec $BINARY \ 
         --pidfile $PIDFILE 
       RETVAL=$? 
       test $RETVAL -eq 0 && touch $PIDFILE 
       eend $? 
} 

stop() { 
       ebegin "Stopping VM additions service timesync" 
       start-stop-daemon --stop --exec $BINARY \ 
         --pidfile $PIDFILE 
       eend $? 
} 

Now you are ready for start Linux Additions

If you are running on VirtualServer You may also want this (do not use it on VirtualPC)

[edit] Error Messages

In case you get the folowing error message:

make[2]: *** [/lib/modules/vmadd/module/vpc-mod.o] Error 1
make[1]: *** [_module_/lib/modules/vmadd/module] Error 2
make[1]: Leaving directory `/usr/src/kernels/2.6.27.7-134.fc10.i686'
make: *** [vmadd-build-module] Error 2
make: Leaving directory `/lib/modules/vmadd/module'
Could not build kernel module

You need to patch vpc-mod.c and vpc-utils.c

vpc-mod.c

Add #include <linux/fs.h>, before the following source 
#include <linux/signal.h>
#include <linux/sched.h>
#include <linux/interrupt.h>

=== Patched version ===
#include <linux/fs.h>
#include <linux/signal.h>
#include <linux/sched.h>
#include <linux/interrupt.h>

vpc-utils.c

line 105: "ebx", "ecx", "edx", "esi", "edi", "ebp"

delete the ending "ebp" including the "," before

[edit] Compiling the modules on 2.6.31 and higher kernels

The patches above are required. The makefile that comes with vmadd does not work, but it can be altered to work (from The Linux Kernel Module Programming Guide):

Makefile:

# Makefile altered for 2.6 kernels

KVERSION ?= $(shell name -r)
KDIR     ?= /lib/modules/$(KVERSION)/build
OUTDIR   ?= /lib/modules/$(KVERSION)/misc

obj-m += vmadd.o
vmadd-objs := vpc-mod.o vpc-utils.o

all:
        make -C $(KDIR) M=$(PWD) modules
clean:
        make -C $(KDIR) M=$(PWD) clean
install: vmadd.ko
        mkdir -p $(OUTDIR)
        install -m 0400 -o 0 -g 0 vmadd.ko $(OUTDIR)

Remember to use tabs after the all, clean and install rules.
