Since the deallocator is passed into the constructor of
a hash table it is not desirable to pass it into each
function again. Remove it from all functions, but provide
a virHashSteal to allow a item to be removed from a hash
table without deleteing it.
* src/util/hash.c, src/util/hash.h: Remove deallocator
param from all functions. Add virHashSteal
* src/libvirt_private.syms: Add virHashSteal
* src/conf/domain_conf.c, src/conf/nwfilter_params.c,
src/nwfilter/nwfilter_learnipaddr.c,
src/qemu/qemu_command.c, src/xen/xm_internal.c: Update
for changed hash API
Done mechanically with:
$ git grep -l '\bDEBUG0\? *(' | xargs -L1 sed -i 's/\bDEBUG0\? *(/VIR_&/'
followed by manual deletion of qemudDebug in daemon/libvirtd.c, along
with a single 'make syntax-check' fallout in the same file, and the
actual deletion in src/util/logging.h.
* src/util/logging.h (DEBUG, DEBUG0): Delete.
* daemon/libvirtd.h (qemudDebug): Likewise.
* global: Change remaining clients over to VIR_DEBUG counterpart.
Use it in all places where a memory or storage request size is converted
to a larger granularity. This avoids requesting too small memory or storage
sizes that could result from the truncation done by a simple division.
This extends the round up fix in 6002e0406c
to the whole codebase.
Instead of reporting errors for odd values in the VMX code round them up.
Update the QEMU Argv tests accordingly as the original memory size 219200
isn't a even multiple of 1024 and is rounded up to 215 megabyte now. Change
it to 219100 and 219136. Use two different values intentionally to make
sure that rounding up works.
Update virsh.pod accordingly, as rounding down and rejecting are replaced
by rounding up.
I broke 'make check' with commit 04197350 by unconditionally
emitting 'hap=' in xen xm driver. Only emit 'hap=' if
xendConfigVersion >= 3. I've tested sending 'hap=' to a Xen 3.2
machine without support for hap setting and verified that xend
silently drops the unrecognized setting.
xen-unstable c/s 16931 introduced a per-domain setting for hvm
guests to enable/disable hardware assisted paging. If disabled,
software techniques such as shadow page tables are used. If enabled,
and the feature exists in underlying hardware, hardware support for
paging is used.
This provides implementation for mapping HAP setting to/from
domxml/native formats in xen drivers.
This extends the XML syntax for <graphics> to allow a password

eg
<graphics type='vnc' port='5900' autoport='yes' keymap='en-us' passwd='12345' passwdValidTo='2010-04-09T15:51:00'/>
The timestamp is in UTC.

Although this patch adds a distinction between maximum vcpus and
current vcpus in the XML, the values should be identical for all

a distinction be made.
In general, virDomainGetInfo should prefer the current vcpus.

Adding parsing code for memory tunables in the domain xml file

Adds a new specific test
The xm internal xen driver only supports disk and network devices to be
added to a guest. On an attempt to attach any other device the xm driver
used VIR_ERR_XML_ERROR which resulted in a completely bogus error
message:
error: Failed to attach device from pci.xml
error: XML description for unknown device is not well formed or invalid
Xen supports on_crash actions coredump-{destroy,restart}. libvirt
cannot parse config returned by xend that contains either of these
actions
xen52 # xm li -l test | grep on_crash
(on_crash coredump-restart)
xen52 # virsh dumpxml test
error: internal error unknown lifecycle type coredump-restart
This patch adds a new virDomainLifecycleCrash enum and appends
the new options to existing destroy, restart, preserve, and
rename-restart options.
According to <xen-3.4.3/tools/python/xen/xm/create.py:158>
gopts.var('bootargs', val='NAME',
fn=set_value, default=None,
use="Arguments to pass to boot loader")
the "bootloader_args" parameter needs to be translated into "bootargs"
when using "virsh domxml-to-native xen-xm".
The reverse direction (domxml-from-native) is already okay.
This patch fixes domxml-to-native and adds two test files to catch this
problem.

All <console> devices now export a <target> type attribute. QEMU defaults
to 'serial', UML defaults to 'uml, xen can be either 'serial' or 'xen'
depending on fullvirt. Understandably there is lots of test fallout.
This will be used to differentiate between a serial vs. virtio console for
QEMU.

There is actually a difference between the character device type (serial,
parallel, channel, ...) and the target type (virtio, guestfwd). Currently
they are awkwardly conflated.
Start to pull them apart by renaming targetType -> deviceType. This is
an entirely mechanical change.

To allow the new virDomainUpdateDeviceFlags() API to be universally
used with all drivers, this patch adds an impl to all the current
drivers which support CDROM or Floppy disk media change via the
current virDomainAttachDeviceFlags API
* src/qemu/qemu_driver.c, src/vbox/vbox_tmpl.c,
src/xen/proxy_internal.c, src/xen/xen_driver.c,
src/xen/xend_internal.c: Implement media change via the
virDomainUpdateDeviceFlags API
* src/xen/xen_driver.h, src/xen/xen_hypervisor.c,
src/xen/xen_inotify.c, src/xen/xm_internal.c,
src/xen/xs_internal.c: Stubs for Xen driver entry points
A few more non-literal format strings in error log messages have crept
in. Fix them in the standard way - turn the format string into "%s"
with the original string as the arg.
This extends the XML to allow for
<clock offset='timezone' timezone='Europe/Paris'/>
This is useful if the admin has not configured any timezone on the
host OS, but still wants to synchronize a guest to a specific one.
* src/conf/domain_conf.h, src/conf/domain_conf.c: Support extra
'timezone' attribute on clock configuration
* docs/schemas/domain.rng: Add 'timezone' attribute
* src/xen/xend_internal.c, src/xen/xm_internal.c: Reject configs
with a configurable timezone
The XML will soon be extended to allow more than just a simple
localtime/utc boolean flag. This change replaces the plain
'int localtime' with a separate struct to prepare for future
extension
* src/conf/domain_conf.c, src/conf/domain_conf.h: Add a new
virDomainClockDef structure
* src/libvirt_private.syms: Export virDomainClockOffsetTypeToString
and virDomainClockOffsetTypeFromString
* src/qemu/qemu_conf.c, src/vbox/vbox_tmpl.c, src/xen/xend_internal.c,
src/xen/xm_internal.c: Updated to use new structure for localtime
* src/xen/xm_internal.c (xenXMConfigGetULong): Remove useless and
misleading test (always false) for val->str == NULL before code that
always dereferences val->str. "val" comes from virConfGetValue, and
at that point, val->str is guaranteed to be non-NULL.
(xenXMConfigGetBool): Likewise.
* src/util/conf.c (virConfSetValue): Ensure that vir->str is never NULL,
not even if someone tries to set such a value via virConfSetValue.
Replace free(virBufferContentAndReset()) with virBufferFreeAndReset().
Update documentation and replace all remaining calls to free() with
calls to VIR_FREE(). Also add missing calls to virBufferFreeAndReset()
and virReportOOMError() in OOM error cases.
Xen HVM guests with PV drivers end up with two network interfaces for
each configured interface. One of them being emulated by qemu and the
other one paravirtual. As this might not be desirable, the attached
patch provides a way for users to specify that only paravirtual network
interface should be presented to the guest.
The configuration was inspired by qemu/kvm driver, for which users can
specify model='virtio' to use paravirtual network interface.
The patch adds support for model='netfront' which results in
type=netfront instead of type=ioemu (or nothing for newer xen versions)
in guests native configuration. Xen's qemu ignores interfaces with
type != ioemu and only paravirtual network device will be seen in the
guest.
Four possible configuration scenarios follow:
- no model specified in domain's XML
- libvirt will behave like before this change; it will set
type=ioemu for HVM guests on xen host which is not newer than
XEND_CONFIG_MAX_VERS_NET_TYPE_IOEMU
- covered by existing tests
- PV guest, any model
- no functional change, model is passed as is (and ignored by the
hypervisor)
- covered by existing tests (e.g., *-net-e1000.*)
- HVM guest, model=netfront
- type is set to "netfront", model is not specified
- covered by new *-net-netfront.* tests
- HVM guest, model != netfront
- type is set to "ioemu", model is passed as is
- covered by new *-net-ioemu.* tests
The fourth scenario feels like a regression for xen newer than
XEND_CONFIG_MAX_VERS_NET_TYPE_IOEMU as users who had a model specified
in their guest's configuration won't see a paravirtual interface in
their guests any more. On the other hand, the reason for specifying a
model is most likely the fact that they want to use such model which
implies emulated interface. Users of older xen won't be affected at all
as their xen provides paravirtual interface regardless of the type used.
- src/xen/xend_internal.c: add netfront support for the xend backend
- src/xen/xm_internal.c: add netfront support for the XM serialization too
Introduce a new type="dir" mode for <disks> that allows use of
QEMU's virtual FAT block device driver. eg

<readonly/>
</disk>
gets turned into
-drive file=fat:floppy:/tmp/test,if=floppy,index=0

A character device's target (it's interface in the guest) had only a
single property: port. This patch is in preparation for adding targets
which require other properties.
Since this changes the conf type for character devices this affects
a number of drivers:
* src/conf/domain_conf.[ch] src/esx/esx_vmx.c src/qemu/qemu_conf.c
src/qemu/qemu_driver.c src/uml/uml_conf.c src/uml/uml_driver.c
src/vbox/vbox_tmpl.c src/xen/xend_internal.c src/xen/xm_internal.c:
target properties are moved into a union in virDomainChrDef, and a
targetType field is added to identify which union member should be
used. All current code which touches a virDomainChrDef is updated both
to use the new union field, and to populate targetType if necessary.
