Hi.
Libvirt tryes to extract kvm version from the string "QEMU PC emulator version <major>.<minor>.<micro> (kvm-<version>)..." For examle, # kvm -help | head -1 QEMU PC emulator version 0.10.0 (kvm-85), Copyright (c) 2003-2008 Fabrice Bellard
The problem occures if you are trying to run it on the devel version of kvm: # kvm -help | head -1 QEMU PC emulator version 0.10.0 (kvm-devel), Copyright (c) 2003-2008 Fabrice Bellard The virParseNumber() obvioulsy fails on the "devel" string here. I propose to setup `kvm_version' to 1000 (that's enough, I think) in that case, so all checks, such as if (kvm_version > 74) ... will pass.
Yeah, I've run into this too. The problem with just setting kvm_version to a huge number is that if you built a kvm development snapshot a long time in the past, and you run it now, then you will be turning on features your old development snapshot didn't necessarily have. On the other hand, if you are running development snapshots, you get to keep both pieces when things break. Maybe we can set the kvm_version number very high like you say, but also dump a warning message out to the logfile saying this is a development version so the poor sap who has to debug something like this has a fighting chance. Any other opinions? -- Chris Lalancette
