4.4.1. QEMU

4.4.1.1. Simulation

class simbricks.components.qemu.simulation.qemu.QemuSim(simulation: Simulation)

machine: str | None

Optionally define the machine type. The above will be passed as ‘-machine q35’ to QEMU.

If set to None, no ‘-machine’ option is passed.

accel: list[str]

Define the virtualization accelerator. Each flag will be appended with a separate -accel parameter.

The above will become ‘-accel kvm -accel tcg’.

resreq_cores() → int

Number of cores this simulator requires during execution.

This is used for scheduling multiple runs and experiments.

resreq_mem() → int

Number of memory in MB this simulator requires during execution.

This is used for scheduling multiple runs and experiments.
