Subject: [PATCH v8 12/15] libxl: set correct nic type depending on the guest
Date: Wed, 4 Jul 2012 12:59:33 +0100	[thread overview]
Message-ID: <1341403176-50715-13-git-send-email-roger.pau@citrix.com> (raw)
In-Reply-To: <1341403176-50715-1-git-send-email-roger.pau@citrix.com>

Fix the use of nic type, which results in the following for each type
of domain:

 * HVM: let the user choose, if none specified use VIF_IOEMU.
 * HVM with stubdom: use VIF always.
 * PV: use VIF always.
