Hi, the command virsh qemu-monitor-command ubuntu_vm --hmp --cmd "info tlb" fails with "error: Unable to encode message payload". I found a bugtracker entry for a similiar error [1], but I don't if this is the same error (message too large). I also don't know how large an info tlb message is. Preferably I would not have to recompile libvirt just to issue this monitor command.. Then I thought about circumventing the error by connecting directly to the qemu monitor via netcat, but I found a thread [2] that says I cannot add my own "-monitor tcp:..." to the Qemu commandline arguments. Could someone help me with this?
