Handling I/O Bursts With QEMU 2.6

The recent release of QEMU 2.6 has support for allowing guests to do bursts of I/O for a configurable amount of time, whereby the I/O level exceeds the normally allowed limits.

Our friends at the consulting firm Igalia have written a blog post about I/O bursts with QEMU 2.6.

The post was specifically authored by Alberto Garcia and covers the new I/O burst support available in QEMU 2.6+ as well as previous QEMU I/O options. If you rely upon QEMU and normally enforce I/O limits but would be interested in supporting bursts as well for users, check out that post.
