Nm, turns out qemu-kvm needs to be started with the full path (/usr/libexec/qemu-kvm -hda....) then virsh goes past this error.

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.
