Subject: libxl: fix AttachDeviceConfig on hostdev type
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=56945e1374bd254148643d76a98fba9be67fba15;p=people%2Fliuw%2Flibxenctrl-split%2Flibvirt.git

libxl: fix AttachDeviceConfig on hostdev type

After attach-device a <hostdev> with --config, new device doesn't
show up in dumpxml and in guest.

To fix that, set dev->data.hostdev = NULL after work so that the
pointer is not freed, since vmdef has the pointer and still need it.
