How to access the Monitor Console in QEMU?
You can access the monitor console only if you started the virtual machine directly with the qemu-system- ARCH command and are viewing its graphical output in a native QEMU window.
Can a QEMU monitor manage Virtual Machine snapshots?
Managing snapshots in QEMU monitor is not officially supported by SUSE yet. The information found in this section may be helpful in specific cases. Virtual Machine snapshots are snapshots of the complete virtual machine including the state of CPU, RAM, and the content of all writable disks.
How to start a virtual machine with QEMU-KVM?
Following is an example of a working qemu-kvm command line: Disables ACPI support. Try to use it if VM Guest reports problems with ACPI interface. QEMU starts with CPU stopped. To start CPU, enter c in QEMU monitor. For more information, see Chapter 16, Administrating Virtual Machines with QEMU Monitor .
Where does QEMU store its process identification number?
Stores the QEMU’s process identification number (PID) in a file. This is useful if you run QEMU from a script. By default QEMU creates basic virtual devices even if you do not specify them on the command line.
Is the socket file always empty in QEMU?
QEMU also permits -qmp in place of -monitor, providing a JSON-based interface; that might be more robust for programmatic control, but I never tried it. A socket file on disk is always empty. It doesn’t store data; it’s just an arbitrary handle for programs to open communications.
How to redirect QEMU monitor to telnet?
There are a couple options for redirecting the QEMU monitor. One way is to have QEMU offer access to its monitor via telnet: Then, QEMU can be scripted by piping commands to telnet. This is fine as long as the output of commands can be discarded since the telnet session will probably close too quickly for visual feedback:
How to get device index numbers from QEMU monitor?
Move the active mouse pointer to the specified coordinates dx, dy with the optional scroll axis dz. Change the state of the mouse buttons (1=left, 2=middle, 4=right). Set which mouse device receives events. Device index numbers can be obtained with the info mice command.
