## Config KATA QEMU
After executing the above script, two files will be generated under the directory `/usr/share/kata-containers/` by default, namely `kata-flash0.img` and `kata-flash1.img`. Next we need to change the configuration file of `kata qemu`, which is in `/opt/kata/share/defaults/kata-containers/configuration-qemu.toml` by default, specify in the configuration file to use the UEFI ROM installed above. The above is an example of `kata deploy` installation. For package management installation, please use `kata-runtime env` to find the location of the configuration file. Please refer to the following configuration.
```
[hypervisor.qemu]
# -pflash can add image file to VM. The arguments of it should be in format
# of ["/path/to/flash0.img", "/path/to/flash1.img"]
pflashes = ["/usr/share/kata-containers/kata-flash0.img", "/usr/share/kata-containers/kata-flash1.img"]
```
## Run for test
Let's test if the memory hotplug is ready for Kata after install the UEFI ROM. Make sure containerd is ready to run Kata before test.
