@ -23,9 +23,9 @@ The ``virt`` machine supports the following devices:
* 1 generic PCIe host bridge
* The fw_cfg device that allows a guest to obtain data from QEMU
Note that the default CPU is a generic RV32GC/RV64GC. Optional extensions
can be enabled via command line parameters, e.g.: ``-cpu rv64,x-h=true``
enables the hypervisor extension for RV64.
The hypervisor extension has been enabled for the default CPU, so virtual
machines with hypervisor extension can simply be used without explicitly
declaring.
