Before this patch, the translation function still needs a second ugly
helper function to actually format the command line for qemu. But if we
do the right stuff in the translation function, we don't have to bother
with the second function any more.
This patch removes the messy qemuBuildVolumeString function and changes
qemuTranslateDiskSourcePool to set stuff up correctly so that the
regular code paths meant for volumes can be used to format the command
line correctly.
For this purpose a new helper "qemuDiskGetActualType()" is introduced to
return the type of the volume in a pool.
As a part of the refactor the qemuTranslateDiskSourcePool function is
fixed to do decisions based on the pool type instead of the volume type.
This allows to separate pool-type-specific stuff more clearly and will
ease addition of other pool types that will require certain other
operations to get the correct pool source.
The previously fixed tests should make sure that we don't break stuff
that was working before.
In the 'directory' and 'netfs' storage pools, a user can see
both 'file' and 'dir' storage volume types, to know when they
can descend into a subdirectory. But in a network-based storage
pool, such as the upcoming 'gluster' pool, we use 'network'
instead of 'file', and did not have any counterpart for a
directory until this patch. Adding a new volume type
'network-dir' is better than reusing 'dir', because it makes
it clear that the only way to access 'network' volumes within
that container is through the network mounting (leaving 'dir'
for something accessible in the local file system).

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)

Both virStoragePoolFree and virStorageVolFree reset the last error,
which might lead to the cryptic message:
An error occurred, but the cause is unknown
When the volume wasn't found, virStorageVolFree was called with NULL,
leading to an error:

This patch changes it to:
Storage volume not found: no storage vol with matching name 'tomato'
During qemuTranslateDiskSourcePool() execution, if the srcpool has been
defined with authentication information, then for iSCSI pools copy the
authentication and host information to virDomainDiskDef.
The difference with already supported pool types (dir, fs, block)
is: there are two modes for iscsi pool (or network pools in future),
one can specify it either to use the volume target path (the path
showed up on host) with mode='host', or to use the remote URI qemu
supports (e.g. file=iscsi://example.org:6000/iqn.1992-01.com.example/1)
with mode='direct'.
For 'host' mode, it copies the volume target path into disk->src. For
'direct' mode, the corresponding info in the *one* pool source host def
is copied to disk->hosts[0].

This changes the helpers qemu{Add,Remove}SharedDisk into
qemu{Add,Remove}SharedDevice, as most of the code in the helpers
can be reused for scsi host device.
To track the shared scsi host device, first it finds out the
device path (e.g. /dev/s[dr]*) which is mapped to the sg device,
and use device ID of the found device path (/dev/s[dr]*) as the
hash key. This is because of the device ID is not unique between
between /dev/s[dr]* and /dev/sg*, e.g.
% sg_map
/dev/sg0 /dev/sda
/dev/sg1 /dev/sr0
% ls -l /dev/sda
brw-rw----. 1 root disk 8, 0 May 2 19:26 /dev/sda
%ls -l /dev/sg0
crw-rw----. 1 root disk 21, 0 May 2 19:26 /dev/sg0
"Shared disk" is not only the thing we should care about after "scsi
hostdev" is introduced. A same scsi device can be used as "disk" for
one domain, and as "scsi hostdev" for another domain at the same time.
That's why this patch renames qemu_driver->sharedDisks. Related functions
and structs are also renamed.
Adding a VNC WebSocket support for QEMU driver. This functionality is
in upstream qemu from commit described as v1.3.0-982-g7536ee4, so the
capability is being recognized based on QEMU version for now.
The source code base needs to be adapted as well. Some files
include virutil.h just for the string related functions (here,
the include is substituted to match the new file), some include
virutil.h without any need (here, the include is removed), and
some require both.
After 78d7c3c5 we are strdup()-ing path to qemu-bridge-helper.
However, the check for its return value is missing. So it is
possible we've ignored the OOM error silently.
To support "shareable" for volume type disk, we have to translate
the source before trying to add the shared disk entry. To achieve
the goal, this moves the helper qemuTranslateDiskSourcePool into
src/qemu/qemu_conf.c, and introduce an internal only member (voltype)
for struct _virDomainDiskSourcePoolDef, to record the underlying
volume type for use when building the drive string.
Later patch will support "shareable" volume type disk.
Currently when getting an instance of virCgroupPtr we will
create the path in all cgroup controllers. Only at the virt
driver layer are we attempting to filter controllers. This
is bad because the mere act of creating the dirs in the
controllers can have a functional impact on the kernel,
particularly for performance.
Update the virCgroupForDriver() method to accept a bitmask
of controllers to use. Only create dirs in the controllers
that are requested. When creating cgroups for domains,
respect the active controller list from the parent cgroup

Use the qemu specific callback to fill this data in the qemu driver as
it's the only place where it was used and fix tests as the qemu test
capability object didn't configure the defaults for the tests.
This patch removes the defaultDiskDriverName from the virCaps
structure. This particular default value is used only in the qemu driver
so this patch uses the recently added callback to fill the driver name
if it's needed instead of propagating it through virCaps.
This patch implements the devices post parse callback and uses it to fill
the default qemu network card model into the XML if none is specified.
Libvirt assumes that the network card model for qemu is the "rtl8139".
Record this in the XML using the new callback to avoid user
confusion.
This patch adds instrumentation that will allow hypervisor drivers to
fill and validate domain and device definitions after parsed by the XML
parser.
With this patch, after the XML is parsed, a callback to the driver is
issued requesting to fill and validate driver specific details of the
configuration. This allows to use sensible defaults and checks on a per
driver basis at the time the XML is parsed.
Two callback pointers are stored in the new virDomainXMLConf object:
* virDomainDeviceDefPostParseCallback (devicesPostParseCallback)
- called for a single device parsed and for every single device in a
domain config. A virDomainDeviceDefPtr is passed along with the
domain definition and virCaps.
* virDomainDefPostParseCallback, (domainPostParseCallback)
- A callback that is meant to process the domain config after it's
parsed. A virDomainDefPtr is passed along with virCaps.
Both types of callbacks support arbitrary opaque data passed for the
callback functions.
Errors may be reported in those callbacks resulting in a XML parsing
failure.
This patch is the result of running:
for i in $(git ls-files | grep -v html | grep -v \.po$ ); do
sed -i -e "s/virDomainXMLConf/virDomainXMLOption/g" -e "s/xmlconf/xmlopt/g" $i
done
and a few manual tweaks.
The virCaps structure gathered a ton of irrelevant data over time that.
The original reason is that it was propagated to the XML parser
functions.
This patch aims to create a new data structure virDomainXMLConf that
will contain immutable data that are used by the XML parser. This will
allow two things we need:
1) Get rid of the stuff from virCaps
2) Allow us to add callbacks to check and add driver specific stuff
after domain XML is parsed.
This first attempt removes pointers to private data allocation functions
to this new structure and update all callers and function that require
them.
At least one caller may call qemuSharedDiskEntryFree with NULL as the
first argument. Let's make the function similar to other *Free functions
and do nothing in such case.
Commit f506a4c1 changed virSetUIDGID() to be a noop
when uid/gid are -1, while it used to be a noop when
they are <= 0.
The changes in this commit broke creating new VMs in GNOME Boxes
as qemuDomainCheckDiskPresence gets called during domain creation/startup,
which in turn calls virFileAccessibleAs which fails after calling
virSetUIDGID(0, 0) (Boxes uses session libvirtd). virSetUIDGID is called with
(0, 0) as these are the default user/group values in virQEMUDriverConfig
for session libvirtd.
This commit changes virQEMUDriverConfigNew to use -1 as the unpriviledged
uid/gid. I've also looked at the various places where cfg->user is used,
and they all seem to handle -1 correctly.
There is a lock ordering problem in the QEMU close callback
APIs.
When starting a guest we have a lock on the VM. We then
set a autodestroy callback, which acquires a lock on the
close callbacks.
When running auto-destroy, we obtain a lock on the close
callbacks, then run each callbacks - which obtains a lock
on the VM.
This causes deadlock if anyone tries to start a VM, while
autodestroy is taking place.
The fix is to do autodestroy in 2 phases. First obtain
all the callbacks and remove them from the list under
the close callback lock. Then invoke each callback
from outside the close callback lock.

qemu: Avoid deadlock in autodestroy
Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
To avoid having to hold the qemu driver lock while iterating through
close callbacks and calling them. This fixes a real deadlock when a
domain which is being migrated from another host gets autodestoyed as a
result of broken connection to the other host.
The hash entry is changed from "ref" to {ref, @domains}. With this, the
caller can simply call qemuRemoveSharedDisk, without afraid of removing
the entry belongs to other domains. qemuProcessStart will obviously
benifit from it on error codepath (which calls qemuProcessStop to do
the cleanup).
Based on moving various checking into qemuAddSharedDisk, this
avoids the caller using it in wrong ways. Also this adds two
new checking for qemuCheckSharedDisk (disk device not 'lun'
and kernel doesn't support unpriv_sgio simply returns 0).
With the majority of fields in the virQEMUDriverPtr struct
now immutable or self-locking, there is no need for practically
any methods to be using the QEMU driver lock. Only a handful
of helper APIs in qemu_conf.c now need it
Currently the APIs for managing the shared disk list take
a virHashTablePtr as the primary argument. This is bad
because it requires the caller to deal with locking of
the QEMU driver. Switch the APIs to take the full
virQEMUDriverPtr instance

Currently the virQEMUDriverPtr struct contains an wide variety
of data with varying access needs. Move all the static config
data into a dedicated virQEMUDriverConfigPtr object. The only
locking requirement is to hold the driver lock, while obtaining
an instance of virQEMUDriverConfigPtr. Once a reference is held
on the config object, it can be used completely lockless since
it is immutable.
NB, not all APIs correctly hold the driver lock while getting
a reference to the config object in this patch. This is safe
for now since the config is never updated on the fly. Later
patches will address this fully.

The autodestroy callback code has the following function
called from a hash iterator
qemuDriverCloseCallbackRun(void *payload,
const void *name,
void *opaque)

...
char *uuidstr = name
...
dom = closeDef->cb(data->driver, dom, data->conn);
if (dom)
virObjectUnlock(dom);
virHashRemoveEntry(data->driver->closeCallbacks, uuidstr);
}
The closeDef->cb function may well cause the current callback
to be removed, if it shuts down 'dom'. As such the use of
'uuidstr' in virHashRemoveEntry is accessing free'd memory.
We must make a copy of the uuid str before invoking the
callback to be safe.

Curently security labels can be of type 'dynamic' or 'static'.
If no security label is given, then 'dynamic' is assumed. The
current code takes advantage of this default, and avoids even
saving <seclabel> elements with type='dynamic' to disk. This
means if you temporarily change security driver, the guests
can all still start.
With the introduction of sVirt to LXC though, there needs to be
a new default of 'none' to allow unconfined LXC containers.
This patch introduces two new security label types
- default: the host configuration decides whether to run the
guest with type 'none' or 'dynamic' at guest start
- none: the guest will run unconfined by security policy
The 'none' label type will obviously be undesirable for some
deployments, so a new qemu.conf option allows a host admin to
mandate confined guests. It is also possible to turn off default
confinement
