Peter Krempa 7200212536 qemu: Extract more information about qemu drives
Extract whether a given drive has a tray and whether there is no image

Negative logic for the image insertion is chosen so that the flag is set

Peter Krempa f6721a3d9a qemu: process: Refresh ejectable media tray state on VM start
Empty floppy drives start with tray in "open" state and libvirt did not
refresh it after startup. The code that inserts media into the tray then
waited until the tray was open before inserting the media and thus
floppies could not be inserted.

Fritz Elfert 89f7475da7 util: Remove disabling of autologin for iscsi-targets
https://bugzilla.redhat.com/show_bug.cgi?id=1331552

Instead of disabling auto-login of all scsi targets (even those
that do not "belong" to libvirt), use iscsiadm's "--op nonpersistent"
during discovery of iSCSI targets (e.g. "iscsiadm --mode discovery
--type sendtargets") in order to avoid the node database being altered
which led to the need for the "large hammer" approach taken by
commit id '3c12b654'.

This commit removes the virISCSITargetAutologin adjustment (eg. the setting
of node.startup to "manual"). The iscsiadm command has supported this mode
of operation as of commit id 'ad873767' to open-iscsi.

John Ferlan da72346486 iscsi: Add exit status checking for virISCSIGetSession
Utilize the exit status parameter for virCommandRunRegex in order to
check the return error from the 'iscsiadm --mode session' command.
Without this enabled, if there are no sessions running then virCommandRun
would have displayed an error such as:

    2016-05-13 15:17:15.165+0000: 10920: error : virCommandWait:2553 :
               internal error: Child process (iscsiadm --mode session)
               unexpected exit status 21: iscsiadm: No active sessions.

It is possible that for certain paths (when probe is true) we only care
whether it's running or not to make certain decisions.  Spitting out
the error for those paths is unnecessary.

If we do have a situation where probe = false and there's an error,
then display the error from iscsiadm if it's there.

Jim Fehlig 2d302d7902 xlconfigtests: use qemu-xen in all test data files
Some of the test configuration files in tests/xlconfigdata
use the old qemu-dm as the emulator. Many of the configuration
features tested (spice, rbd, multi-usb) are not even usable with
the old qemu. Change these files to use the new qemu-xen (also
known as qemu upstream) emulator.

Note: This change fixes xlconfigtest failures when the old
qemu is actually installed on the system. During device post
parse, the libxl driver attempts to invoke the emulator to
determine if it is the old or new qemu so it can properly set
video RAM defaults. With the old qemu installed, the default
video RAM was set differently than the expected value.
Changing all the test data files to use qemu-xen ensures
predictable results wrt default video RAM size.

Jim Fehlig 50b9de5b03 libxl: don't attempt to probe a non-existent emulator
When probing the <emulator> with '-help' to determine if
it is the old qemu, errors are reported if the emulator
doesn't exist

libvirt:  error : internal error: Child process
(/usr/lib/xen/bin/qemu-dm -help) unexpected exit status 127:
libvirt:  error : cannot execute binary /usr/lib/xen/bin/qemu-dm:
No such file or directory

Avoid the probe if the specified emulator doesn't exist,
squelching the error. There is no behavior change since
libxlDomainGetEmulatorType() would return
LIBXL_DEVICE_MODEL_VERSION_QEMU_XEN if the probe failed
via virCommandRun().

Ján Tomko 41d837ae89 Call per-device post-parse callback even on implicit video
Commit 6879be48 moved adding of an implicit video device after XML
parsing. As a result, libxlDomainDeviceDefPostParse() is no longer
called to set the default vram when adding an implicit device.
Commit 6879be48 assumes virDomainVideoDefaultRAM() will set the
default vram, but it returns 0 if the domain virtType is
VIR_DOMAIN_VIRT_XEN. Attempting to start an HVM domain with vram=0
results in

error: unsupported configuration: videoram must be at least 4MB for CIRRUS

The default vram setting for Xen HVM domains depends on the device
model used (qemu-xen vs qemu-traditional), hence setting the
default is deferred to libxlDomainDeviceDefPostParse().

Call the device post-parse callback even for implicit video,
to fill out the default vram even for VIR_DOMAIN_VIRT_XEN.

Daniel P. Berrange b4d8e5d331 libvirt.spec: remove duplicate files from -docs package

Shivaprasad G Bhat 6bc1f546de send default USB controller in xml to destination during migration
The default USB controller is not sent to destination as the older versions
of libvirt(0.9.4 or earlier as I see in commit log of 409b5f54) didn't
support them. For some archs where the support started much later can
safely send the USB controllers without this worry. So, send the controller
to destination for all archs except x86. Moreover this is not very applicable
to x86 as the USB controller has model ich9_ehci1 on q35 and for pc-i440fx,
there cant be any slots before USB as it is fixed on slot 1.

The patch fixes a bug that, if the USB controller happens to occupy
a slot after disks/interfaces and one of them is hot-unplugged, then
the default USB controller added on destination takes the smallest slot
number and that would lead to savestate mismatch and migration
failure. Seen and verified on PPC64.

Martin Kletzander 082deb52ac qemu: Regenerate VNC socket paths
Similarly to what commit 7140807917 did with some internal paths,
clear vnc socket paths that were generated by us.  Having such path in
the definition can cause trouble when restoring the domain.  The path is
generated to the per-domain directory that contains the domain ID.
However, that ID will be different upon restoration, so qemu won't be
able to create that socket because the directory will not be prepared.

To be able to migrate to older libvirt, skip formatting the socket path
in migratable XML if it was autogenerated.  And mark it as autogenerated
if it already exists and we're parsing live XML.

Best viewed with '-C'.

Laine Stump 46fdaf5d9a qemu: fix error log in qemuAssignPCIAddresses()
This error message was too specific, based on the incorrect assumption
that any error was cause by auto-added bridges:

  failed to create PCI bridge on bus 2: too many devices
  with fixed addresses

In practice you can't know if a bridge with an index <= the bus it's
connecting to was added automatically, or if it was a mistake in
explicit config, and the auto-add problem is going to be dealt with in
a different way in an upcoming patch. The new message is this:

  PCI Controller at index 1 (0x01) has "
  bus='0x02', but bus must be <= index

(note that index is given in both decimal and hex because it is
formatted as decimal in the XML, but bus is formatted as hex, and
displaying the hex value of index makes it easier to see the problem
when index > 9 (which will often be the case with PCIe, since most
controllers only have a single port, not 32 slots as with standard
PCI)).

The values are currently limited to LLONG_MAX which causes some
problems.  QEMU conveniently changed their maximum to 1e15 (1 PB) which
is enough for some time and we need to adapt to that so that we don't
throw "Unknown error" messages.  Strictly limiting these values actually
fixes some corner case values (off-by-one checks in QEMU probably).

Since values out of the new specified range do not overflow anything,
change the type of error as well.

Laine Stump 8ceb0feae3 network: fix DHCPv6 on networks with prefix != 64
According to the dnsmasq manpage, the netmask for IPv4 address ranges
will be auto-deteremined from the interface dnsmasq is listening on,
but it can't do this for IPv6 for some reason - it instead assumes a
network prefix of 64 for all IPv6 address ranges. If this is
incorrect, dnsmasq will refuse to give out an address to clients,
instead logging this message:

 dnsmasq-dhcp[2380]: no address range available for DHCPv6 request via virbr0

This reverts commit 1e9808d3a1.

We shouldn't advertise libvirtd.socket activation, since currently
it means VM/network/... autostart won't work as expected.

We tried to find a middle ground by installing the config file without
an [Install] section, since systemd won't allow .socket to be enabled
without one... or at least it did do that; presently on f24 it allows
activating the socket quite happily. This also caused user confusion[1]

Just remove the socket file. I've filed a new RFE to track coming up
with a solution to the autostart problem[2], we can point users at that

Many had IQN's of just 'iqn.1992-01.com.example' for one disk while using
'iqn.1992-01.com.example/1' for the second disk (same for hostdevs - guess
how they were copied/generated).

Typically (and documented this way), IQN's would include be of the form
'iqn.1992-01.com.example:storage/1' indicating an IQN using "storage" for
naming authority specific string and "/1" for the iSCSI LUN.

So modify the input XML's to use the more proper format - this of course
has a ripple effect on the output XML and the args.

Also note that the "%3A" is generated by the virURIFormat/xmlSaveUri
to represent the colon.

Jason J. Herne 791c90cb8d Libvirt: virTypedParamsValidate: Fix detection of multiple parameters
virTypedParamsValidate currently uses an index based check to find
duplicate parameters. This check does not work. Consider the following
simple example:

We have only 2 keys
A  (multiples allowed)
B  (multiples NOT allowed)

We are given the following list of parameters to check:
A
A
B

If you work through the validation loop you will see that our last iteration
through the loop has i=2 and j=1. In this case, i > j and keys[j].value.i will
indicate that multiples are not allowed. Both conditionals are satisfied so
an incorrect error will be given: "parameter '%s' occurs multiple times"

This patch replaces the index based check with code that remembers
the name of the last parameter seen and only triggers the error case if
the current parameter name equals the last one. This works because the
list is sorted and duplicate parameters will be grouped together.

In reality, we hit this bug while using selective block migration to migrate
a guest with 5 disks. 5 was apparently just the right number to push i > j
and hit this bug.

virsh migrate --live guestname --copy-storage-all
              --migrate-disks vdb,vdc,vdd,vde,vdf
              qemu+ssh://dsthost/system

John Ferlan 58650d53c7 Resolve a couple of memory leaks
Commit id '4b75237f' seems to have triggered Coverity into finding
at least one memory leak in xen_xl.c for error path for cleanup where
the listenAddr would be leaked. Reviewing other callers, it seems that
qemu_parse_command.c would have the same issue, so just it too.

Jim Fehlig 06791c14f7 libxl: use LIBXL_API_VERSION 0x040200
To ensure the libvirt libxl driver will build with future versions
of Xen where the libxl API may change in incompatible ways,
explicitly use LIBXL_API_VERSION 0x040200. The libxl driver
does use new libxl APIs that have been added since Xen 4.2, but
currently it does not make use of any changes made to existing
APIs such as libxl_domain_create_restore or libxl_set_vcpuaffinity.
The version can be bumped if/when the libxl driver consumes the
changed APIs.

Further details can be found in the following discussion thread

Richard W.M. Jones 843ffe8abd Add functions for handling exponential backoff loops.
In a few places in libvirt we busy-wait for events, for example qemu
creating a monitor socket.  This is problematic because:

 - We need to choose a sufficiently small polling period so that
   libvirt doesn't add unnecessary delays.

 - We need to choose a sufficiently large polling period so that
   the effect of busy-waiting doesn't affect the system.

The solution to this conflict is to use an exponential backoff.

This patch adds two functions to hide the details, and modifies a few
places where we currently busy-wait.

Move some API specific documentation out of -docs package and into
-devel, and some end user docs out of -devel and into -docs, then
drop the -devel dep on -docs. This is more in line with the suggested
Fedora guidelines.

Cole Robinson a0a1f39adf util: Add virGettextInitialize, convert the code
Take setlocale/gettext error handling pattern from tools/virsh-*
and use it for all standalone binaries via a new shared
virGettextInitialize routine. The virsh* pattern differed slightly
from other callers. All users now consistently:

* Ignore setlocale errors. virsh has done this forever, presumably for
  good reason. This has been partially responsible for some bug reports:
