I shared dvd burner device /dev/cd0 with the windows server 2012 guest (using passthrough) and attempted to burn dvd from the guest using InfraRecorder program. In the process sound playing on the host was cycling several times for a prolonged periods of time. After a while all of a sudden InfraRecorder said that progress is 100%. But I don't believe disk was even touched for writing. Instead host log got many error messages, and eventually /dev/cd0 disappeared (!!!). Why those error messages weren't passed to the guest program? Did anybody actually succeed in burning dvds from guests? Is this supposed to work?
