qemuctl
qemuctl(1) qemuctl(1)
NAME
qemuctl - Graphical control for qemu
SYNTAX
qemuctl [-suspend-dir <dir>] [-suspend-file <filename>] [-qemu <qemu>] [-nowakeup] qemu-options
DESCRIPTION
qemuctl is a gui that controls a qemu process with the built-in monitor of qemu. So you can change devices, suspend machines, save screen-
shots, ...
If you suspend a machine it will do the following macro:
stop
screendump "suspend-dir/suspend-file.ppm"
savevm "suspend-dir/suspend-file.vm"
commit
quit
You can afterwards resume the machine with:
qemuctl -suspend-dir suspend-dir -suspend-file suspend-file your_qemu_options
the suspend-files will then be deleted
or
qemuctl -loadvm suspend-dir/suspend-file.vm your_qemu_options
Be aware that you can't use the "-monitor" option with qemuctl, because it needs the control over the monitor. The option "-serial stdio"
can't be used, too.
OPTIONS
-suspend-file <filename>
This option is normaly used by qemuctl to support suspend and wakeup. qemuctl can then find the vm-state-file in its folders and
wakeup the virtual machine. If the file is there the qemuctl waes up the virtual machine and deletes the file afterwards. On suspend
the vm-state-file is then stored as the <filename> with the .vm ending and the screenshot is stored as the <filename> with the .ppm
ending.
Default filename is "suspend".
-suspend-dir <dir>
This is the dir where the suspend files would be stored or expected.
Default is current dir.
-nowakeup
Don't wake up even if the vm-file is there. Suspend still works.
Default is to wake up using the vm-file if it is there.
-qemu <qemu>
The qemu variation to use. It can be qemu or kvm.
Default is qemu.
qemu-options
Use qemu-options for the launch of qemu. See qemu(1) for further details.
FILES
none
ENVIRONMENT VARIABLES
none
EXAMPLES
To use the suspend file 'Debian 3.1' and store/search it in the '/qemu' dir:
qemuctl -suspend-file "Debian 3.1" -suspend-dir "/qemu" -boot c -hda hda.raw
Alternativly you can run it with default suspend filenames:
qemuctl -boot c -hda hda.raw
