[libvirt] [PATCH 2/3] Debug: Remove unnecessary errors reported while parsing non-existent sysfs files.
Sample from current logs:
error : virFileReadAll:1290 : Failed to open file '/sys/class/net/tap3/operstate':
No such file or directory
error : virNetDevGetLinkInfo:1895 : unable to read: /sys/class/net/tap3/operstate: No such
file or directory
These have no useful data point and are redundant.
