All other stateful drivers are linked directly to libvirtd
instead of libvirt.so. Link the secret driver to libvirtd too.
* daemon/Makefile.am: link the secret driver to libvirtd
* daemon/libvirtd.c: add #ifdef WITH_SECRETS blocks
* src/Makefile.am: don't link the secret driver to libvirt.so
* src/libvirt_private.syms: remove the secretRegister symbol
If using a remote access, sometimes an RPC entry point is not
available, and currently we just end up with a raw:
error: unknown procedure: xxx
error, while this should be more cleanly reported as an unsupported
entry point like for local access
* src/remote/remote_driver.c: convert missing remote entry points into
the unsupported feature error
When querying about a domain from 0.3.3 (or RHEL 5.3) domain located
on a 0.6.3 (RHEL-5) machine, the errors are not properly reported.
This patch from Olivier Fourdan <ofourdan@redhat.com> , slightly
modified to not change the semantic when the domain os details cannot
be provided
* src/xen/proxy_internal.c src/xen/xen_hypervisor.c: add some missing
error reports
Found while trying to cross-compile libvirt on Fedora 12 for Windows.
gnulib redefines 'close' to 'close_used_without_including_unistd_h'
in sys/socket.h if winsock2.h is present and unistd.h has not been
included before sys/socket.h. Reorder some includes to fix this.
The option --with-sasl defaults to 'check', but an inverted test logic
lets the SASL check fail with an error instead of disabling SASL.
Fix the test logic so SASL support gets disabled if SASL is missing and
--with-sasl is set to check.
The testlogic for $PKG_CONFIG was inverted, checking for an empty string
before using PKG_CHECK_MODULES. Use -x instead of -z and add an else branch
to the if checking for $GNUTLS_FOUND = no to add -lgcrypt in case the
GnuTLS libraries are detected by pkg-config.
* src/qemu/qemu_conf.h: Remove QEMU_CMD_FLAG_0_12 and just leave
the lone JSON flag
* src/qemu/qemu_conf.c: Enable JSON on QEMU 0.13 or later, but
leave it disabled for now
The Xen code for making HVM VT-d PCI passthrough attach and detach
wasn't working properly:
1) In xenDaemonAttachDevice(), we were always trying to reconfigure
a PCI passthrough device, even the first time we added it. This was
because the code in virDomainXMLDevID() was not checking xenstore for
the existence of the device, and always returning 0 (meaning that
the device already existed).
2) In xenDaemonDetachDevice(), we were trying to use "device_destroy"
to detach a PCI device. While you would think that is the right
method to call, it's actually wrong for PCI devices. In particular,
in upstream Xen (and soon in RHEL-5 Xen), device_configure is actually
used to destroy a PCI device.
To fix the attach
problem I add a lookup into xenstore to see if the device we are
trying to attach already exists. To fix the detach problem I change
it so that for PCI detach (only), we use device_configure with the
appropriate sxpr to do the detachment.
* src/xen/xend_internal.c: don't use device_destroy for PCI devices
and fix the other issues.
* src/xen/xs_internal.c src/xen/xs_internal.h: add
xenStoreDomainGetPCIID()
The XML XPath for detecting JSON in the running VM statefile was
wrong causing all VMs to get JSON mode enabled at libvirtd restart.
In addition if a VM was running a JSON enabled QEMU once, and then
altered to point to a non-JSON enabled QEMU later the 'monJSON'
flag would not get reset to 0.
* src/qemu/qemu_driver.c: Fix setting/detection of JSON mode
As Paul Jenner pointed out all other statistics commands use the
singular form
* tools/virsh.c: rename dommemstats to dommemstat as well as function
name and associated structures
The code for connecting to a server tries each socket in turn
until it finds one that connects. Unfortunately for TLS sockets
if it connected, but failed TLS handshake it would treat that
as a failure to connect, and try the next socket. This is bad,
it should have reported the TLS failure immediately.
$ virsh -c qemu://somehost.com/system
error: unable to connect to libvirtd at 'somehost.com': Invalid argument
error: failed to connect to the hypervisor
$ ./tools/virsh -c qemu://somehost.com/system
error: server certificate failed validation: The certificate hasn't got a known issuer.
error: failed to connect to the hypervisor
* src/remote/remote_driver.c: Stop trying to connect if the
TLS handshake fails
Enable virDomainMemoryStats in the python API. dom.memoryStats() will return a
dictionary containing the supported statistics. A dictionary is required
because the meaining of each quantity cannot be inferred from its index in a
list.
* python/generator.py: reenable bindings for this entry point
* python/libvirt-override-api.xml python/libvirt-override.c: the
generator can't handle this new function, add the new binding,
and the XML description
Define a new command 'dommemstats' to report domain memory statistics. The
output format is inspired by 'domblkstat' and 'domifstat' and consists of
tag/value pairs, one per line. The command can complete successfully and
print no output if virDomainMemoryStats is supported by the driver, but not
the guest operating system.
Sample output:
swap_in 0
swap_out 0
major_fault 54
minor_fault 58259
unused 487680
available 502472
All stats referring to a quantity of memory (eg. all above except major and
minor faults) represent the quantity in KBytes.
* tools/virsh.c: implements the new command
Use a dynamically sized xdr_array to pass memory stats on the wire. This
supports the addition of future memory stats and reduces the message size
since only supported statistics are returned.
* src/remote/remote_protocol.x: provide defines for the new entry point
* src/remote/remote_driver.c daemon/remote.c: implement the client and
server side
* daemon/remote_dispatch_args.h daemon/remote_dispatch_prototypes.h
daemon/remote_dispatch_ret.h daemon/remote_dispatch_table.h
src/remote/remote_protocol.c src/remote/remote_protocol.h: generated
stubs
Support for memory statistics reporting is accepted for qemu inclusion.
Statistics are reported via the monitor command 'info balloon' as a comma
seprated list:
(qemu) info balloon
balloon: actual=1024,mem_swapped_in=0,mem_swapped_out=0,major_page_faults=88,minor_page_faults=105535,free_mem=1017065472,total_mem=1045229568
Libvirt, qemu, and the guest operating system may support a subset of the
statistics defined by the virtio spec. Thus, only statistics recognized by
components will be reported.
* src/qemu/qemu_driver.c src/qemu/qemu_monitor_text.[ch]: implement the
new entry point by using info balloon monitor command
Set up the types for the domainMemoryStats function and insert it into the
virDriver structure definition. Because of static initializers, update
every driver and set the new field to NULL.
* include/libvirt/libvirt.h.in: new API
* src/driver.h src/*/*_driver.c src/vbox/vbox_tmpl.c: add the new
entry to the driver structure
* python/generator.py: fix compiler errors, the actual python binding is
implemented later
If a virtual machine is destroyed on a ESX server then immediately
undefining this virtual machine on a vCenter may fail, because the
vCenter has not been informed about the status change yet. Therefore,
destroy a virtual machine on a vCenter if available, so the vCenter
is up-to-date when the virtual machine should be undefined.
Undefining a virtual machine on an ESX server leaves a orphan on the
vCenter behind. So undefine a virtual machine on a vCenter if available
to fix this problem.
If an ESX host is managed by a vCenter, it knows the IP address of the
vCenter. Setting the vCenter query parameter to * allows to connect to the
vCenter known to an ESX host without the need to specify its IP address
or hostname explicitly.
esxDomainLookupByUUID() and esxDomainIsActive() lookup a domain by asking
ESX for all known domains and searching manually for the one with the
matching UUID. This is inefficient. The VI API allows to lookup by UUID
directly: FindByUuid().
* src/esx/esx_driver.c: change esxDomainLookupByUUID() and esxDomainIsActive()
to use esxVI_LookupVirtualMachineByUuid(), also reorder some functions to
keep them in sync with the driver struct
Questions can block tasks, to handle them automatically the driver can answers
them with the default answer. The auto_answer query parameter allows to enable
this automatic question handling.
* src/esx/README: add a detailed explanation for automatic question handling
* src/esx/esx_driver.c: add automatic question handling for all task related
driver functions
* src/esx/esx_util.[ch]: add handling for the auto_answer query parameter
* src/esx/esx_vi.[ch], src/esx/esx_vi_methods.[ch], src/esx/esx_vi_types.[ch]:
add new VI API methods and types and additional helper functions for
automatic question handling
Commit 33a198c1f6 increased the gcrypt
version requirement to 1.4.2 because the GCRY_THREAD_OPTION_VERSION
define was added in this version.
The configure script doesn't check for the gcrypt version. To support
gcrypt versions < 1.4.2 change the virTLSThreadImpl initialization
to use GCRY_THREAD_OPTION_VERSION only if it's defined.
* configure.in: If you pass libraries in the LDFLAGS variable, and then
try AC_CHECK_FUNCS to find whether a function is present or not,
it'll fail badly when using the --as-needed linker flag. Instead,
pass the libraries through the LIBS library, so that they are passed
after the conftest.c source file and the tests are done properly.
* configure.in: With the previous logic, if libhal_get_all_devices
function was not found, HAVE_HAL would be defined for the preprocessor
but it wouldn't be enabled in automake conditionals, causing the final
link to fail with missing references to HAL entries.
