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.
