Sorry this didn't receive a response until now... but this change is definitely not acceptable as is. It forces -no-kvm for all qemu-system-* binaries, which is not correct: KVM should be usable with many qemu-system binaries like arm, aarch64, ppc64, etc Given the age of this bug, closing as deferred. But if you can still reproduce with modern libvirt and qemu, please provide - The error you were receiving that you were trying to fix - The XML of a VM you were trying to run |
Created attachment 670773 [details] fix Description of problem: Libvirt is unable to run software qemu emulation (domain type="qemu") if kvm is not present, because qemu monitor is not working and libvirt probing kvm executables without -no-kvm module, so every call ended with "no kvm module" and libvirt unable to find qemu support. This bug has a known workaround: create a shell script that will add cmd arg params can call qemu. Version-Release number of selected component (if applicable): 1.0.0 and higher How reproducible: always Steps to Reproduce: 1. install qemu without monitor (non tested with monitor support) on a system that lacks kvm module. 2. run libvirt 3. run virsh capabilities | grep hvm Actual results: nothing is found Expected results: there should be results for software hvm emulation Additional info: I'm attaching a patch, that fixes situation assuming that qemu-system-* executable is no hvm.
