Previously, an IO error presented when the following conditions were met:
* A bond had been created with two VLAN networks, one
with MTU 5000 and the other with MTU 9000
* A virtual machine was created with the above-mentioned
* The networks were deactivated on the virtual machine
* SetupNetwork was opened, and the bond was broken
Previously, when these conditions had been met, an IO error presented and supervdsm restarted.
An update to VDSM now makes sure that supervdsm is not restarted with IO errors present.
