Hi,
I've found a viable solution to this problem.
I've putted following script into /etc/pm/sleep.d:
#!/bin/bash
#
# A script to pause virtual machines before going into suspend
declare -r SAVES_DIRECTORY="/var/lib/libvirt/qemu/save"
for_each_line() {
while read -r line; do $1 "$line"; done
}
save_virtual_machine() {
TARGET_FILE="$SAVES_DIRECTORY/$1.save"
echo "Saving $1 (to $TARGET_FILE)"
virsh "connect qemu:///system;save $1 '$TARGET_FILE'"
}
virsh 'connect qemu:///system;list' | \
sed -n '/^\s\+[0-9]\+\s\+.\+\s\+running.*/p' | \
sed -e 's/^\s\+[0-9]\+\s\+\(.\+\)\s\+running.*/\1/' | \
for_each_line save_virtual_machine
This saves all running virtual machines when going to sleep.
Maybe this solution can find its way into debian? I could write
a python-script that uses the libvirt instead of this shell
script...
