investigation of openvswitch code showed, that early versions

|| '_' || '-' || '.'. If the string that ovs-vsctl wants to
output contains any other character it is escaped. You want to be
looking at ovsdb_atom_to_string() which handles outputting of a
single string and calls string_needs_quotes() and possibly
json_serialize_string() in openvswitch code base.
Since the interfaces are usually named "vhost-userN" we are
facing a problem where with one version we get the name in double
quotes and with another we get plain name without funny business.
Because of json involved I thought, let's make ovs-vsctl output

ovs-vsctl ignores --format=json. But with a little help of

1) virNetDevGenerateName() can be called with a name already filled
in, and in that case it is an effective NOP.
2) because virNetDevGenerate() will always find an unused name, there
is no need to retry device creation in a loop - if it fails the
first time, it would fail any subsequent time as well.
that, combined with the aforementioned parser change allow us to
simplify virNetDevMacVLanCreateWithVPortProfile() - we no longer need
any extra code to determine if a template "AutoName" was requested,
and don't need a separate code path for creating the device in the

would if no name was given.

lxc: don't try to reserve macvtap name for LXC domains
Commit 729a06c41 added code to the LXC driver (patterned after similar
code in the QEMU driver) that called
virNetDevMacVlanReserveName(net->ifname) for all type='direct'
interfaces during a libvirtd restart, to prevent other domains from
attempting to use a macvtap device name that was already in use by a
domain.
But, unlike a QEMU domain, when an LXC domain creates a macvtap
device, that device is almost immediately moved into the namespace of
the container (and it's then renamed, but that part isn't
important). Because of this, the LXC driver doesn't keep track (in
net->ifname) of the name used to create the device (as the QEMU driver
does).
The result of this is that if libvirtd is restarted while there is an
active LXC domain that has <interface type='direct'>, libvirtd will
segfault (since virNetDevMacVLanReserveName() doesn't check for a NULL
pointer).
The fix is to just not call that function in the case of the LXC
driver, since it is pointless anyway.

Previously there was no way to differentiate between this function 1)
encountering an error while reading the pci config, and 2) determining
that the device in question is a conventional PCI device, and so has
no Express Capabilities.
The difference between these two conditions is important, because an
unprivileged libvirtd will be unable to read all of the pci config (it
can only read the first 64 bytes, and will get ENOENT when it tries to
seek past that limit) even though the device is in fact a PCIe device.
This patch changes virPCIDeviceFindCapabilityOffset() to put the
determined offset into an argument of the function (rather than
sending it back as the return value), and to return the standard "0 on
success, -1 on failure". Failure is determined by checking the value
of errno after each attemptd read of the config file (which can only
work reliably if errno is reset to 0 before each read, and after
virPCIDeviceFindCapabilityOffset() has finished examining it).
(NB: if the config file is read successfully, but no Express
Capabilities are found, then the function returns success, but the
returned offset will be 0 (which is an impossible offset for Express
Capabilities, and so easily recognizeable).

return 0 or 1. Change the function itself to return a bool, and the
caller to just directly set the flag in the virPCIDevice.

qemu: use g_autoptr for a virPCIDevice
The one instance of a virPCIDevice in
qemuDomainDeviceCalculatePCIConnectFlags() needs to be converted to
use g_autoptr as a prerequisite for a bugfix. It's in this patch by
itself (rather than in a patch converting all virPCIDevice usages to
g_autoptr) to simplify any backport of said bugfix.

Nwfilter can be edited by the user and we don't want to overwrite the editings.
Also the filters in %{datadir} does not have UUIDs and these are generated on
libvirtd start. Thus this patch also fixes regeneration of UUIDs on libvirtd
update.
