Connecting a tap device to an Open vSwitch is done by adding a "port"
to the switch with the ovs-vsctl "add-port" command. The port will
have the same name as the tap device, but it is a separate entity, and
can survive beyond the destruction of the tap device (although under
normal circumstances the port will be deleted around the same time the
tap device is deleted).
This makes it possible for a port of a particular name to already
exist at the time libvirt calls ovs-vsctl to add that port. The
original commit of Open vSwitch support (commit df81004632, libvirt
0.9.10, Feb. 2012) used the "--may-exist" option to the add-port
command to indicate that a port of the desired name might already
exist, and that it was okay to simply re-use this port (rather than
failing with an error message).
Then in commit 33445ce8446d9 (libvirt 1.2.7, April 2014) the command
was changed to use "--if-exists del-port blah" instead of
"--may-exist". The reason given was that there was a bug in OVS where
a stale port would be unusable even though it still existed; the
workaround was to forcibly delete any existing port prior to adding
the new port (of the same name). This is the ovs-vsctl command still
in use by libvirt today.
It recently came up in the discussion of a bug concerning guest packet
loss during OpenStack upgrades (https://bugzilla.redhat.com/1963164)
that the bug in OVS that necessitated the del-port workaround was
fixed quite a long time ago (August 2015):
e21c6643a0
thus rendering the workaround in libvirt unnecessary. The assertion in
that discussion is that this workaround is now the cause of the packet
loss being experienced during OpenStack upgrades. I'm not convinced
this is the case, but it does appear that there is no reason to carry
this workaround in libvirt any longer, so this patch reverts the code
back to the original behavior (using "--may-exist" instead of
"--if-exists del-port").

The iscsi-direct storage pool backend works merely like this: a
connection is established to the target (usually done via
virStorageBackendISCSIDirectSetConnection()), intended action is
executed (e.g. reporting LUNs, volume wiping), and at the end the
connection is closed via virISCSIDirectDisconnect().
The problem is that virISCSIDirectDisconnect() reports its own
errors which may overwrite error that occurred during LUN
reporting, or volume wiping or whatever.
To fix this, use virErrorPreserveLast() + virErrorRestore()
combo, which either preserves previously reported error message,
or is NOP if there's no error reported.

Cloud-Hypervisor is a KVM virtualization using hypervisor. It
functions similarly to qemu and the libvirt Cloud-Hypervisor driver
uses a very similar structure to the libvirt driver.
The biggest difference from the libvirt perspective is that the
"monitor" socket is seperated into two sockets one that commands are
issued to and one that events are notified from. The current
implementation only uses the command socket (running over a REST API
with json encoded data) with future changes to add support for the
event socket (to better handle shutdowns from inside the VM).
This patch adds support for the following initial VM actions using the
Cloud-Hypervsior API:
* vm.create
* vm.delete
* vm.boot
* vm.shutdown
* vm.reboot
* vm.pause
* vm.resume
To use the Cloud-Hypervisor driver, the v15.0 release of
Cloud-Hypervisor is required to be installed.
Some additional notes:
* The curl handle is persistent but not useful to detect ch process
shutdown/crash (a future patch will address this shortcoming)
* On a 64-bit host Cloud-Hypervisor needs to support PVH and so can
emulate 32-bit mode but it isn't fully tested (a 64-bit kernel and
32-bit userspace is fine, a 32-bit kernel isn't validated)
