Re: [libvirt] [PATCH] virt-aa-helper: allow sysfs path used for vhost-scsi

When a vhost scsi device is hotplugged virt-aa-helper is called to add the respective path. For example the config: <hostdev mode='subsystem' type='scsi_host' managed='no'> <source protocol='vhost' wwpn='naa.50014059de6fba4f'/> </hostdev> Will call it to add: /sys/kernel/config/target/vhost//naa.50014059de6fba4f But in general /sys paths are filtered in virt-aa-helper.c:valid_path To allow the path used for vhost-scsi we need to add it to the list of known and accepted overrides.
