XML schema for CPU flags
Firstly, CPU topology and model with optional features have to be
advertised in host capabilities:
<host>
<cpu>
<arch>ARCHITECTURE</arch>
<features>
<!-- old-style features are here -->
</features>
<model>NAME</model>
<topology sockets="S" cores="C" threads="T"/>
<feature name="NAME"/>
</cpu>
...
</host>
Secondly, drivers which support detailed CPU specification have to
advertise
it in guest capabilities:
<guest>
...
<features>
<cpuselection/>
</features>
</guest>
And finally, CPU may be configured in domain XML configuration:
<domain>
...
<cpu match="MATCH">
<model>NAME</model>
<topology sockets="S" cores="C" threads="T"/>
<feature policy="POLICY" name="NAME"/>
</cpu>
</domain>
Where MATCH can be one of:
- 'minimum' specified CPU is the minimum requested CPU
- 'exact' disable all additional features provided by host CPU
- 'strict' fail if host CPU doesn't exactly match
POLICY can be one of:
- 'force' turn on the feature, even if host doesn't have it
- 'require' fail if host doesn't have the feature
- 'optional' match host
- 'disable' turn off the feature, even if host has it
- 'forbid' fail if host has the feature
'force' and 'disable' policies turn on/off the feature regardless of its
availability on host. 'force' is unlikely to be used but its there for
completeness since Xen and VMWare allow it.
'require' and 'forbid' policies prevent a guest from being started on a host
which doesn't/does have the feature. 'forbid' is for cases where you disable
the feature but a guest may still try to access it anyway and you don't want
it to succeed.
'optional' policy sets the feature according to its availability on host.
When a guest is booted on a host that has the feature and then migrated to
another host, the policy changes to 'require' as we can't take the feature
away from a running guest.
Default policy for features provided by host CPU but not specified in domain
configuration is set using match attribute of cpu tag. If 'minimum' match is
requested, additional features will be treated as if they were specified
with 'optional' policy. 'exact' match implies 'disable' policy and 'strict'
match stands for 'forbid' policy.
* docs/schemas/capability.rng docs/schemas/domain.rng: extend the
RelaxNG schemas to add CPU flags support
The description mismatched the actual structure since the video element
was introduced. The nvram attribute is actually called vram. Specify the
unit of the vram attribute.
The owner and group in the documentation examples were confusingly given as
'0744'. They should be numeric uid and gid. Changed the examples to use the
default uid and gid assigned to qemu in F12.
* docs/formatstorage.html.in: Change example owner and group in volume XML
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.
* docs/ChangeLog.xsl docs/newapi.xsl docs/site.xsl: change all
stylesheets to output UTF-8 HTML instead of ISO Latin 1 which was
breaking on some people names.
Introduce a new type="dir" mode for <disks> that allows use of
QEMU's virtual FAT block device driver. eg
<disk type='dir' device='floppy'>
<source dir='/tmp/test'/>
<target dev='fda' bus='fdc'/>
<readonly/>
</disk>
gets turned into
-drive file=fat:floppy:/tmp/test,if=floppy,index=0
Only read-only disks are supported with virtual FAT mode
* src/conf/domain_conf.c, src/conf/domain_conf.h: Add type="dir"
* docs/schemas/domain.rng: Document new disk type
* src/xen/xend_internal.c, src/xen/xm_internal.c: Raise error for
unsupported disk types
* tests/qemuxml2argvdata/qemuxml2argv-disk-cdrom-empty.args: Fix
empty disk file handling
* tests/qemuxml2argvdata/qemuxml2argv-disk-drive-fat.args,
tests/qemuxml2argvdata/qemuxml2argv-disk-drive-fat.xml,
tests/qemuxml2argvdata/qemuxml2argv-floppy-drive-fat.args,
tests/qemuxml2argvdata/qemuxml2argv-floppy-drive-fat.xml
tests/qemuxml2argvtest.c: Test QEMU vitual FAT driver
* src/qemu/qemu_conf.c: Support generating fat:/some/dir type
disk args
* src/security/security_selinux.c: Temporarily skip labelling
of directory based disks
0.7.3 was broken
* configure.in docs/news.html.in: release of 0.7.4
* configure.in libvirt.spec.in: require netcf >= 0.1.4
* src/Makefile.am: node_device/node_device_udev.h was missing from
NODE_DEVICE_DRIVER_UDEV_SOURCES breaking compilation on platforms with
udev
For backward compatibility we used to add the tty path as
a tty attribute on console of type pty, duplicating the value
now found in source/@path, but the Relax-NG grammar wasn't
extended for this
<console type='pty' tty='/dev/pts/8'>
<source path='/dev/pts/8'/>
<target port='0'/>
</console>
* docs/schemas/domain.rng: allow an optional tty attribute
containing a devicePath
* docs/drivers.html.in: list the ESX driver
* docs/drvesx.html.in: the new ESX driver documentation
* docs/hvsupport.html.in: add the ESX driver to the matrix
* docs/index.html.in, docs/sitemap.html.in: list the ESX driver
* src/esx/esx_driver.c: fix and cleanup some comments
Debian's /etc/xml/catalog doesn't contain system identifiers, so use
public identifiers instead.
* docs/Makefile.am: use public instead of system identifier
* docs/site.xsl: use matching public identifier
* docs/formatdomain.html.in: refactors the existing character device
documentation to make it explicit which directives configure the guest
interface, and which configure the host interface.
This patch is the result of running the following command in the docs
directory: sed -i 's/\t/ /g; s/\s*$//' *.html.in
* docs/*.html.in:convert tabs into 8 spaces and remove trailing whitespace
* src/internal.h (ATTRIBUTE_SENTINEL): New, it's a ggc feature and
protected as such
* src/util/buf.c (virBufferStrcat): Use it.
* src/util/ebtables.c (ebtablesAddRemoveRule): Use it.
* src/util/iptables.c (iptableAddRemoveRule: Use it.
* src/util/qparams.h (new_qparam_set, append_qparams): Use it.
* docs/apibuild.py: avoid breaking the API generator with that new
internal keyword macro
allows the following to be specified in a domain:
<channel type='pipe'>
<source path='/tmp/guestfwd'/>
<target type='guestfwd' address='10.0.2.1' port='4600'/>
</channel>
* proxy/Makefile.am: add network.c as dep of domain_conf.c
* docs/schemas/domain.rng src/conf/domain_conf.[ch]: extend the domain
schemas and the parsing/serialization side for the new construct
QEmu support will add the following on the qemu command line:
-chardev pipe,id=channel0,path=/tmp/guestfwd
-net user,guestfwd=tcp:10.0.2.1:4600-chardev:channel0
* src/qemu/qemu_conf.c: Add argument output for channel
* tests/qemuxml2(argv|xml)test.c: Add test for <channel> domain syntax
This patch adds an optional attribute to the <bootp> tag, that
allows to specify a TFTP server address other than the address of
the DHCP server itself.
This can be used to forward the BOOTP settings of the host down to the
guest. This is something that configurations such as Xen's default
network achieve naturally, but must be done manually for NAT.
* docs/formatnetwork.html.in: Document new attribute.
* docs/schemas/network.rng: Add it to schema.
* src/conf/network_conf.h: Add it to struct.
* src/conf/network_conf.c: Add it to parser and pretty printer.
* src/network/bridge_driver.c: Put it in the dnsmasq command line.
* tests/networkxml2xmlin/netboot-proxy-network.xml
tests/networkxml2xmlout/netboot-proxy-network.xml
tests/networkxml2xmltest.c: add new tests
* src/conf/storage_conf.c src/conf/storage_conf.h: extend the enums
and values
* docs/schemas/storagepool.rng: add to the list of storage pool type
formats
- mpath pools weren't listed
- scsi pools were missing an adapter section
- iscsi pools were missing an auth section
- Logical pools do not require a source name to be specified
The domain/os/type element may have an arch specified without having
a machine variant specified. In fact, this is what python-virtinst
does when defining a guest.
* docs/schemas/domain.rng: allow missing machine type
Removes some auto-generated files still under version control.
It also moves the rule for generating NEWS into the Makefile.am
that's in the same directory as the output file to avoid confusion
* docs/libvirt-api.xml, docs/libvirt-refs.xml, NEWS: Remove
auto-generated files from source control
* Makefile.am: Add rule for generating NEWS file
* docs/Makefile.am: Remove rule for generating NEWS file
Simplify the doTunnelMigrate() method by pulling out the code
which opens/closes the virConnectPtr object into a parent
method
* qemu/qemu_driver.c: Add doPeer2PeerMigrate which then calls
doTunnelMigrate with dconn & dom_xml
* docs/drvqemu.html.in: include documentation for AppArmor sVirt
confinement
* examples/apparmor/TEMPLATE examples/apparmor/libvirt-qemu
examples/apparmor/usr.lib.libvirt.virt-aa-helper
examples/apparmor/usr.sbin.libvirtd: example templates and
configuration files for SVirt Apparmor when using KVM/QEmu
The devhelp/ directory files depend on libvirt-api.xml being
uptodate, but automake always processes SUBDIRS before the
current directory. So devhelp would be built and then the
libvirt-api.xml re-build, invalidating the devhelp data again.
To fix this all the rules for devhelp are moved directly
into the docs/Makefile.am allowing make to see the global
dependancy chain and thus build things in the correct order
* docs/Makefile.am: Add rules for devhelp rebuild
* docs/devhelp/Makefile.am: Remove devhelp rebuild
* configure.in: Remove docs/devhelp/Makefile.am
Implementation of tunnelled migration, using a Unix Domain Socket
on the qemu backend. Note that this requires very new versions of
qemu (0.10.7 at least) in order to get the appropriate bugfixes.
Signed-off-by: Chris Lalancette <clalance@redhat.com>
* docs/schemas/domain.rng: allow one <description> tag in the top level
of the <domain> to store user information as text
* src/conf/domain_conf.c src/conf/domain_conf.h: extend the structure
to store this text, grab it at parse time and save it back when
present after <uuid>
Function comments for virStreamEvent{Add,Update,Remove}Callback() are
missing a trailing ':'. Therefore apibuild.py fails to parse the comment
and warns about the missing ':'.
* docs/libvirt-api.xml, docs/libvirt-refs.xml: updated by apibuild.py
* src/libvirt.c: add missing ':' in function comments
