If this enviroment variable is set, the virTestCompareToFile helper
will overwrite the file content we are comparing against, if the
file doesn't exist or it doesn't match the expected input.
This is useful when adding new test cases, or making changes that
generate a lot of output churn.
Fedora doesn't ship OVMF/AAVMF builds in its repos due to licensing
issues, so the recommended way to consume these bits is via Gerd's
nightly repo: https://www.kraxel.org/repos
Let's teach fedora builds about the loader/nvram pairs these packages
installed, so users don't need to edit qemu.conf to get virt-manager
UEFI support.
- Remove all qemu emulators
- Restart libvirtd
- Install qemu emulators
- Call 'virsh version' -> errors
The only thing that will force the qemu driver to refresh it's cached
capablities info is an explict API call to GetCapabilities.
However in the case when the initial caps lookup at driver connect didn't
find a single qemu emulator to poll, the driver is effectively useless
and really can't do anything until it's populated some qemu capabilities
info.
With the above steps, the user would have to either know about the
magic refresh capabilities call, or restart libvirtd to pick up the
changes.
Instead, this patch changes things so that every time a part of th
driver requests access to capabilities info, check to see if
we've previously seen any emulators. If not, force a refresh.
In the case of 'still no emulators found', this is still very quick, so
I can't think of a downside.

This needs to specified in way too many places for a simple validation
check. The ostype/arch/virttype validation checks later in
DomainDefParseXML should catch most of the cases that this was covering.
This revealed that GuestDefaultEmulator was a bit buggy, capable
of returning an emulator that didn't match the passed domain type. Fix
up the test suite input to continue to pass.
This is a helper function to look up all capabilities data for all
the OS bits that are relevant to <domain>. This is
- os type
- arch
- domain type
- emulator
- machine type
This will be used to replace several functions in later commits.
But the internal API stays the same, and we just convert the value as
needed. Not useful yet, but this is the beginning step of using an enum
for ostype throughout the code.
When parsing XML, we validate the passed ostype + arch combo against
the detected hypervisor capabilities. This has led to the following
problem:
- Define x86 qemu guest
- qemu is inadvertently removed from the host
- libvirtd is restarted. fails to parse VM config since arch is removed
- 'virsh list --all' is now empty, user is wondering where their VMs went
Add a new internal flag VIR_DOMAIN_DEF_PARSE_SKIP_OSTYPE_CHECKS. Use
it when loading VM and snapshot configs from disk.
https://bugzilla.redhat.com/show_bug.cgi?id=1043572
If no <os><type> was specified:
before: unknown OS type no OS type
after : xml error: an os <type> must be specified
If an <os><type> is specified that's not in our capabiliities data:
before: unknown OS type: $type
after : unsupported configuration: no support found for os <type> '$type'
VIR_ERR_OS_TYPE is now unused (as it should be frankly) so drop its strings
as well to save our translators some effort.
$ sudo virsh change-media f19 hdc /mnt/data/devel/media/Fedora-16-x86_64-Live-KDE.iso

Right now when building the qemu command line, we try to do various
unconditional validations of the guest CPU against the host CPU. However
this checks are overly applied. The only time we should use the checks
are:
- The user requests host-model/host-passthrough, or
- When KVM is requsted. CPU features requested in TCG mode are always
emulated by qemu and are independent of the host CPU, so no host CPU
checks should be performed.
Right now if trying to specify a CPU for arm on an x86 host, it attempts
to do non-sensical validation and falls over.
Switch all the test cases that were intending to test CPU validation to
use KVM, so they continue to test the intended code.
Amend some aarch64 XML tests with a CPU model, to ensure things work
correctly.
The check for ISCSI devices was missing a check of subsys type, which
meant we could skip labelling of other host devices as well. This fixes
USB hotplug on F21

If you trigger bug 1033369, we get the error message:
error from service: Invalid argument
Which is a bit too generic to pinpoint what is actually failing. This
changes it to:
error from service: CreateMachine: Invalid argument
Acked-by: Eric Blake <eblake@redhat.com>
This is the only callsite.
We drop use of localerror.name here, because it's not actually useful
to us: rather than the parameter name which received an invalid value
(which was assumed), it's actually the the dbus errno equivalent.
Just use the error string.
Acked-by: Eric Blake <eblake@redhat.com>
Currently VolOpen notifies the user of a potentially non-fatal failure by
returning -2 and logging a VIR_WARN or VIR_INFO. Unfortunately most
callers treat -2 as fatal but don't actually report any message with
the error APIs.
Rename the VOL_OPEN_ERROR flag to VOL_OPEN_NOERROR. If NOERROR is specified,
we preserve the current behavior of returning -2 (there's only one caller
that wants this).
However in the default case, only return -1, and actually use the error
APIs. Fix up a couple callers as a result.
Right now we are parsing the XML as though it's live, which for example
will choke on hardcoded XML like:
<seclabel type='dynamic' model='selinux' relabel='yes'/>
Erroring with:
$ sudo virsh domxml-to-native qemu-argv f
error: XML error: security label is missing
All drivers are fixed, but only qemu was tested.
We were unconditionally removing the device from the host list, when it
should only be done on error.
This fixes USB collision detection when hotplugging the same device to
two guests.
If we hit a collision, we free the USB device while it is still part
of our temporary USBDeviceList. When the list is unref'd, the device
is free'd again.
Make the initial device freeing dependent on whether it is present
in the temporary list or not.
Similar to what Jiri did for cgroup setup/teardown in 05e149f94, push
it all into the device handler functions so we can do the necessary prep
work before claiming the device.
This also fixes hotplugging USB devices by product/vendor (virt-manager's
default behavior):

Restarting an active libvirt-guests.service is the equivalent of
doing:
/usr/libexec/libvirt-guests.sh stop
/usr/libexec/libvirt-guests.sh start
Which in a default configuration will managedsave every running VM,
and then restore them. Certainly not something we should do every
time the libvirt-client RPM is updated.
Just drop the try-restart attempt, I don't know what purpose it
serves anyways.

The following XML is the recommended default clock configuration for
qemu:
<clock offset='utc'>
<timer name='rtc' tickpolicy='catchup'/>
<timer name='pit' tickpolicy='delay'/>
<timer name='hpet' present='no'/>
</clock>
However we weren't testing any of those timer elements.
Again stolen from qemu_driver.c, but dropping all the unneeded bits.
This aims to copy all the current qemu validation checks since that's
the most commonly used real driver, but some of the checks are
completely artificial in the test driver.
This only supports creation of internal snapshots for initial
simplicity.
- Move COPYING* to libvirt-client, so every package pulls them in
- Move AUTHORS ChangeLog.gz NEWS README TODO from -daemon to -docs
- Drop duplicate distribution of docs in -python

When passing in custom driver XML, allow a block like
<domain xmlns:test='http://libvirt.org/schemas/domain/test/1.0'>
...
<test:runstate>5</test:runstate>
</domain>
This is only read at initial driver start time, and sets the initial
run state of the object. This is handy for UI testing.
It's only wired up for domains, since that's the only conf/
infrastructure that supports namespaces at the moment.
Starting with qemu 1.6, the qemu-system-arm vexpress-a9 model has a
hardcoded virtio-mmio transport which enables attaching all virtio
devices.
On the command line, we have to use virtio-XXX-device rather than
virtio-XXX-pci, thankfully s390 already set the precedent here so
it's fairly straight forward.
At the XML level, this adds a new device address type virtio-mmio.
The controller and addressing don't have any subelements at the
moment because we they aren't needed for this usecase, but could
be added later if needed.
Add a test case for an ARM guest with one of every virtio device
enabled.
Similar to the chardev bit, ARM boards depend on the old style '-net nic'
for actually instantiating net devices. But we can't block out
-netdev altogether since it's needed for upcoming virtio support.
And add tests for working ARM XML with console, disk, and networking.
This corresponds to '-sd' and '-drive if=sd' on the qemu command line.
Needed for many ARM boards which don't provide any other way to
pass in storage.
QEMU ARM boards don't give us any way to explicitly wire in
a -chardev, so use the old style -serial options.
Unfortunately this isn't as simple as just turning off the CHARDEV flag
for qemu-system-arm, as upcoming virtio support _will_ use device/chardev.
On my machine, a guest fails to boot if it has a sound card, but not
graphical device/display is configured, because pulseaudio fails to
initialize since it can't access $HOME.
A workaround is removing the audio device, however on ARM boards there
isn't any option to do that, so -nographic always fails.
Set QEMU_AUDIO_DRV=none if no <graphics> are configured. Unfortunately
this has massive test suite fallout.
Add a qemu.conf parameter nographics_allow_host_audio, that if enabled
will pass through QEMU_AUDIO_DRV from sysconfig (similar to
vnc_allow_host_audio)
vhost only works in KVM mode at the moment, and is infact compiled
out if the emulator is built for non-native architecture. While it
may work at some point in the future for plain qemu, for now it's
just noise on the command line (and which contributes to arm cli
breakage).
The function that parses custom driver XML was getting pretty unruly,
split the object parsing into their own functions. Rename some variables
to be consistent across each function. This should be functionally
identical.
File hasn't been really touched for 7 years. And with recent rawhide
changes it contributed to an RPM build failure. Let's drop it.
This also removes installation of a libvirt-python doc dir, so drop
handling of it from the RPM spec.
Because it's a valid combination. p2p still uses a separate channel
for qemu migration, so there's value in letting the user specify a manual
migrate URI for overriding auto-port, or libvirt's FQDN lookup.
What _isn't_ allowed is --migrateuri and TUNNELLED, since there is
no separate migration channel. Disallow that instead
If we are just ejecting media, ret == -1 even after the retry loop
determines that the tray is open, as requested. This means media
disconnect always report's error.
Fix it, and fix some other mini issues:
- Don't overwrite the 'eject' error message if the retry loop fails
- Move the retries decrement inside the loop, otherwise the final loop
might succeed, yet retries == 0 and we will raise error
- Setting ret = -1 in the disk->src check is unneeded
- Fix comment typos

There's been a few bugs about an expected error from polkit:
https://bugzilla.redhat.com/show_bug.cgi?id=873799https://bugzilla.redhat.com/show_bug.cgi?id=872166
The error is:
Authorization requires authentication but no agent is available.
The error means that polkit needs a password, but there is no polkit
agent registered in your session. Polkit agents are the bit of UI that
pop up and actually ask for your password.
Preface the error with the string 'polkit:' so folks can hopefully
make more sense of it.
Most of this deals with moving the libvirt-guests.sh script which
does all the work to /usr/libexec, so it can be shared by both
systemd and traditional init. Previously systemd depended on
the script being in /etc/init.d
Required to fix https://bugzilla.redhat.com/show_bug.cgi?id=789747
Things are supposed to look like:
<machine canonical='pc-0.12'>pc</machine>
But are currently swapped. This can cause many VMs to revert to having
machine type='pc' which will affect save/restore across qemu upgrades.
This commit changes the behavior of LIBVIRT_DEBUG=1 libvirtd:
$ git show 7022b09111
commit 7022b09111
Author: Daniel P. Berrange <berrange@redhat.com>
Date: Thu Sep 27 13:13:09 2012 +0100
Automatically enable systemd journal logging
Probe to see if the systemd journal is accessible, and if
so enable logging to the journal by default, rather than
stderr (current default under systemd).
Previously 'LIBVIRT_DEBUG=1 /usr/sbin/libvirtd' would show all debug
output to stderr, now it send debug output to the journal.
Only use the journal by default if running in daemon mode, or
if stdin is _not_ a tty. This should make libvirtd launched from
systemd use the journal, but preserve the old behavior in most
situations.
When restoring selinux labels after a VM is stopped, any non-standard
path that doesn't have a default selinux label causes the process
to stop and exit early. This isn't really an error condition IMO.
Of course the selinux API could be erroring for some other reason
but hopefully that's rare enough to not need explicit handling.
Common example here is storing disk images in a non-standard location
like under /mnt.
virStorageVolLookupByPath is an API call that virt-manager uses
quite a bit when dealing with storage. This call use BackendStablePath
which has several usleep() heuristics that can be tripped up
and hang virt-manager for a while.
Current example: an empty mpath pool pointing to /dev/mapper makes
_any_ calls to virStorageVolLookupByPath take 5 seconds.
The sleep heuristics are actually only needed in certain cases
when we are waiting for new storage to appear, so let's skip the
timeout steps when calling from LookupByPath.
