## 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. 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 = []
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.
