Hi, I am using "qemu-attach" in virsh to attach to an existing qemu process so I can send monitor commands to it. the VM is started using qemu-kvm -net none -hda ./out.img -m 4G -nographic The VM gets started and the OS boots fine. Then, I start virsh and do a "qemu-attach 44273" which is the PID of the qemu process. virsh # qemu-attach 44273 error: Failed to attach to pid 44273 error: Cannot check QEMU binary qemu-kvm: No such file or directory qemu-kvm is in /usr/libexec. There is a symlink to it from /usr/bin and /bin. The virsh command "create" (for a different VM) works fine. What could be missing? Are there any debug/log messages/config files that can shed some light. Thanks.
