[Bug 781936] Re: libvirtd: operation failed: failed to retrieve chardev info in qemu with 'info chardev'

[Thomas Schweikle]

I could manage to start a kvm, but for some reason I do not understand
there is no output on vnc. The only error message I receive is from kvm
trying to access a tap device I did not create before starting kvm. But
this error doesn't seem to be fatal at all. I am now sure the error is
libvirtd related.

I have used the commandline:
/usr/bin/kvm \
  -S \
  -M pc-0.12 \
  -enable-kvm \
  -m 512 \
  -smp 1,sockets=1,cores=1,threads=1 \
  -name ipcop \
  -uuid 96555d97-9a67-7f06-3a9c-b521a4e43197 \
  -nodefconfig \
  -nodefaults \
  -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/ipcop.monitor,server,nowait \
  -mon chardev=charmonitor,id=monitor,mode=readline \
