Libvirt has stopped working altogether on any VM (windows or linux) on the
qemu/kvm networt and has the following error each time I try to start something:
error: internal error: Failed to start QEMU binary /usr/bin/qemu-system-x86_64 for probing: qemu-system-x86_64: cannot create PID file: Failed to write pid file
If I try to create a new VM on the
qemu/kvm network, I'm given:
Host does not support any virtualization options
However, running and starting VM's on a
qemu/kvm user session network works fine. I have also been able to use the
qemu/kvm network before without problems for a long time, and I'm unsure what's triggered it to stop working now.
I have tried starting the
qemu-system-x86_64 binary from a terminal and that works fine too.
How can I resolve this error?
