The option *IO Thread* can only be used when using a disk with the *VirtIO*
controller, or with the *SCSI* controller, when the emulated controller type is
*VirtIO SCSI single*. With *IO Thread* enabled, QEMU creates one I/O thread per
-storage controller, rather than handling all I/O in the main event loop or vCPU
+storage controller rather than handling all I/O in the main event loop or vCPU
threads. One benefit is better work distribution and utilization of the
underlying storage. Another benefit is reduced latency (hangs) in the guest for
very I/O-intensive host workloads, since neither the main thread nor a vCPU
standard setups.
Some operating systems (such as Windows 11) may require use of an UEFI
-compatible implementation instead. In such cases, you must rather use *OVMF*,
+compatible implementation. In such cases, you must use *OVMF* instead,
which is an open-source UEFI implementation. footnote:[See the OVMF Project https://github.com/tianocore/tianocore.github.io/wiki/OVMF]
There are other scenarios in which the SeaBIOS may not be the ideal firmware to
