@ -595,6 +595,34 @@ traffic increases. We recommend to set this option only when the VM has to
process a great number of incoming connections, such as when the VM is running
as a router, reverse proxy or a busy HTTP server doing long polling.

QEMU can virtualize a few types of VGA hardware. Some examples are:
* *std*, the default, emulates a card with Bochs VBE extensions.
* *vmware*, is a VMWare SVGA-II compatible adapter.
* *qxl*, is the QXL paravirtualized graphics card. Selecting this also
enables SPICE for the VM.
You can edit the amount of memory given to the virtual GPU, by setting
the *memory* option. This can enable higher resolutions inside the VM,
especially with SPICE/QXL.
Selecting Multi-Monitor mode for SPICE (e.g., qxl2 for dual monitors) has
some implications:
* Windows needs a device for each monitor, so if your ostype is some
version of windows, {pve} gives the VM an extra device per monitor.
Each device gets the specified amount of memory.
* Linux VMs, can always enable more virtual monitors, but selecting
a Multi-Monitor mode multiplies the memory given to the device with
the number of monitors.
Selecting *serialX* as display disables the VGA output, and redirects
the Web Console to the selected serial port. A configured memory setting
will be ignored in that case.
