+Date: Tue, 8 May 2012 20:42:44 +0300
+Subject: [PATCH] domain_conf: add "default" to list of valid spice channels
+
+qemu's behavior in this case is to change the spice server behavior to
+require secure connection to any channel not otherwise specified as
+being in plaintext mode. libvirt doesn't currently allow requesting this
+(via plaintext-channel=<channel name>).

+From: Laine Stump <laine@laine.org>
+Date: Tue, 6 Dec 2011 12:47:28 -0500
+Subject: [PATCH] qemu: replace deprecated fedora-13 machine type with pc-0.14
+
+This addresses https://bugzilla.redhat.com/show_bug.cgi?id=754772 .
+It should only be applied to Fedora builds of libvirt, F15 and
+later, so there is no upstream equivalent patch.
+
+Background:
+
+During the lifetime of Fedora 13, some features were backported into
+the F13 build of qemu-kvm from upstream. These features were part of
+the functionality of machine type "pc-0.13" in upstream qemu-kvm, so a
+special "fedora-13" machine type was created for the F13 qemu-kvm.
+Since "fedora-13" became the new "canonical machine type", all new
+domains created with F13 libvirt tools by default contained that
+machine type in their configuration file.
+
+In Fedora 14, a patch was made to qemu to treat the fedora-13 machine
+type as equivalent to "pc-0.13". When Fedora 15 was released, this was
+inadvertently changed to make it equivalent to "pc-0.14".
+
+With the release of Fedora 16, qemu-kvm initially removed support for
+this machine type, which caused failure of many guest configurations
+to start. qemu-kvm subsequently re-added the patch to support
+fedora-13 (as equivalent to pc-0.14), but with the promise that they
+could remove it with the release of Fedora 17. (see
+https://bugzilla.redhat.com/show_bug.cgi?id=748218 ).
+
+Solution:
+
+In order to create a repeat of the recent problems, prior to F17
+existing guest configurations need to be updated to change fedora-13
+to pc-0.14 (which has been determined to be equivalent for all
+practical purposes in both F15 and F16). That's what this patch does:
+
+1) Each time libvirtd is started, it calls virDomainLoadAllConfigs()
+which calls virDomainLoadConfig(); this function has been modified to
+check for os.machine == "fedora-13", and change it to "pc-0.14" then
+write the updated config back to disk.
+
+2) Also, any other time a domain definition is parsed, the parsed
+version in memory is changed to turn "fedora-13" into "pc-0.14". This
+handles domains that had been saved to disk prior to the upgrade, and
+are subsequently restarted.
+
+3) Finally, whenever a domain definition is formatted into a string,
+any occurrence of fedora-13 is replaced with pc-0.14 *directly in the
+virDomainDef* (to avoid multiple warning messages for the same object
+when it's formatted multiple times). This should deal with those cases
+where a domain was running at the time of upgrade, and is later
+saved/snapshotted.
+
+I had considered doing this with some sed commands in the specfile,
+but that wouldn't do anything to help the xml saved in image files.
+
+(Also, one of the xml tests was using the machine type "fedora-13",
+and since that machine type is treated specially by the rest of this
+patch, it was failing. That has been changed in a separate patch,
+which must be applied with this patch, and which *is* also upstream).

+
+    Add support for shared sanlock leases
+    
+    A sanlock lease can be marked as shared (rather
+    than exclusive)  using SANLK_RES_SHARED flag. This
+    adds support for that flag and ensures that in auto
+    disk mode, any shared disks use shared leases. This
+    also makes any read-only disks be completely
+    ignored.
+    
+    These changes remove the need for the option
+    
+      ignore_readonly_and_shared_disks
+    
+    so that is removed
