Description of problem: when changing interface parameters with 'inbound' or 'outbound' option on first time, libvirtd will be crashed. Version-Release number of selected component (if applicable): # rpm -q libvirt libvirt-0.9.9-1.el6.x86_64 How reproducible: always Steps to Reproduce: # virsh start foo Domain demo started # virsh domiftune foo vnet0 inbound.average: 0 inbound.peak : 0 inbound.burst : 0 outbound.average: 0 outbound.peak : 0 outbound.burst : 0 # virsh domiftune foo vnet0 --inbound 10000 error: Unable to set interface parameters error: End of file while reading data: Input/output error or # virsh domiftune demo vnet0 --outbound 10000 # service libvirtd status libvirtd dead but pid file exists Note, it's okay if I change them together on the first time then do separated change for inbound or outbound: # virsh domiftune foo vnet0 --inbound 10000 --outbound 20000 # virsh domiftune foo vnet0 inbound.average: 10000 inbound.peak : 0 inbound.burst : 0 outbound.average: 20000 outbound.peak : 0 outbound.burst : 0 # virsh domiftune foo vnet0 --inbound 30000 # virsh domiftune foo vnet0 inbound.average: 30000 inbound.peak : 0 inbound.burst : 0 outbound.average: 20000 outbound.peak : 0 outbound.burst : 0 Actual results: # service libvirtd status libvirtd dead but pid file exists Expected results: can separately change inbound or outbound for interface device. Additional info: it should be the same issue with bug 771562.
The above comments exist copy-paste error, s/demo/foo/, I verified this issue on different guests(demo and foo) then cross to paste them :(
