There are three 'reasons' +# for a domain to stop: poweroff, reboot, and crash. For each of these you +# may specify: +# "destroy", meaning that the domain is cleaned up as normal; +# "restart", meaning that a new domain is started in place of the old +# one; +# "preserve", meaning that no clean-up is done until the domain is +# manually destroyed (using xm destroy, for example); or +# "rename-restart", meaning that the old domain is not cleaned up, but is +# renamed and a new domain started in its place. +# In the event a domain stops due to a crash, you have the additional options: +# "coredump-destroy", meaning dump the crashed domain's core and then destroy; +# "coredump-restart', meaning dump the crashed domain's core and the restart. +# The default is +# on_poweroff = 'destroy' +# on_reboot = 'restart' +# on_crash = 'restart' +#on_poweroff = 'destroy' +#on_reboot = 'restart' +#on_crash = 'restart' + +#----------------------------------------------------------------------------- +# Configure PVSCSI devices: +# PDEV gives physical SCSI device to be attached to specified guest +# domain by one of the following identifier format. +# - XX:XX:XX:XX (4-tuples with decimal notation which shows +# "host:channel:target:lun") +# - /dev/sdxx or sdx +# - /dev/stxx or stx +# - /dev/sgxx or sgx +# - result of 'scsi_id -gu -s'. +# ex. # scsi_id -gu -s /block/sdb +# 36000b5d0006a0000006a0257004c0000 +# VDEV gives virtual SCSI device by 4-tuples (XX:XX:XX:XX) as +# which the specified guest domain recognize. +#vscsi = [ 'PDEV, VDEV' ] +#vscsi = [ '/dev/sdx, 0:0:0:0' ] + +#============================================================================ +EOF diff --git a/src/os-plugins/plugins/xen/files/run-virt.include b/src/os-plugins/plugins/xen/files/run-virt.include new file mode 100644 index 00000000..36a1d1f4 --- /dev/null +++ b/src/os-plugins/plugins/xen/files/run-virt.include @@ -0,0 +1,157 @@ +# run-virt.include +# ----------------------------------------------------------------------------- +# Copyright (c) 2010 - RZ Uni Freiburg +# Copyright (c) 2010 - OpenSLX GmbH +# +# This program/file is free software distributed under the GPL version 2. +# See http://openslx.org/COPYING +# +# If you have any feedback please consult http://openslx.org/feedback and +# send your feedback to feedback@openslx.org +# +# General information about OpenSLX can be found at http://openslx.org +# ----------------------------------------------------------------------------- +# run-virt.include +# - Include script for running Xen on an OpenSLX client via the run-virt.sh +# or run-vmgrid.sh +################################################################################ + +################################################################################ +### Include general configuration +################################################################################ +if [ -f ${OPENSLX_DEFAULT_CONFDIR}/plugins/${self}/${self}.conf ]; then + . ${OPENSLX_DEFAULT_CONFDIR}/plugins/${self}/${self}.conf +else + writelog "Problems reading config file of ${self} plugin" + exit 1 +fi + +################################################################################ +### Declaration of default variables +################################################################################ + +PLUGINCONFXEN="${PLUGINCONFROOT}/${self}" +# create TMPDIR for all users +mkdir -m 1777 /tmp/${self} 2>/dev/null +# dir for configs +confdir="/tmp/${self}/${USER}/${VM_ID}" +# use vm_shortname for VM name since vm_name can be very long +# add id so we can start more tahn one of the same image +vm_name="${vm_shortname}-${VM_ID}" +conffile=${confdir}/${vm_name} +# define dirs and files which can be removed after exit, be carefull! +rm -rf ${confdir} 2>/dev/null +mkdir -p ${confdir} 2>/dev/null + +xen_kernel=${kernel:-"/boot/vmlinuz-xen"} +xen_ramdisk=${initramfs:-"/boot/initrd-xen"} +xen_extra="xencons=tty 3" +[ -n "${imgname}" ] && xen_disk="disk = [ 'file:${vmpath},hda1,r' ]" + +writelog "Directories:" +writelog "\tConfig dir:\t\t$confdir" + +################################################################################ +### Hardware checks +################################################################################ + +# memory part equal to vmware plugin +# percentage of memory to use for virtualbox in standard case +if [ -n "${forcemem}" ]; then + mem="${forcemem}" +else + permem=30 + if [ "${totalmem}" -ge "1600" ]; then + permem=40 + fi + # check if /tmp is on harddisk + if grep -qe "/dev/.* /tmp " /proc/mounts ; then + permem=60 + id44="1" + # Hack, if more than 2,5G RAM use 40% of Ram and write vmem into Ram as well + # (40% vmware | 40% confdir(vmem...) | 20% host + # VMplayer 2+ issue + # TODO: makes this sense for vbox?
