Subject: [Qemu-devel] [PATCH] xen nic: check tx queue after connect.
Date: Mon,  8 Jun 2009 14:33:26 +0200	[thread overview]
Message-ID: <1244464407-3727-2-git-send-email-kraxel@redhat.com> (raw)
In-Reply-To: <1244464407-3727-1-git-send-email-kraxel@redhat.com>

Needed for savevm/loadvm + migration: In that case the queue might
already have packets on (re-)connect.  The guest wouldn't notify us
because notifications are only sent when stuffing a packet into an
empty queue.
