* autobuild.sh, mingw32-libvirt.spec.in: Enable esx on mingw32
* src/esx/esx_driver.c: Define AI_ADDRCONFIG if not set
* src/esx/esx_util.c, src/esx/esx_vi_types.c: Always use
%lld & friends, since gnulib guarentees we have these
and not the target's own variants
If the bridge device is configured to have IPv6 address and
accept router advertisments, then a malicious guest can send
out bogus advertisments and hijack/DOS host IPv6 connectivity
* src/network_driver.c: Set accept_ra=0, disable_ipv6=1, autoconf=0
for IPv6 sysctl on virual network bridge devices
PCIe DevCap register is actually 32 bits, not 16 bits. Since FLR is
bit 28, we clearly are failing to detect FLR support.
Known to fix device reset with some SR-IOV devices.
* src/pci.c: fix pciDetectFunctionLevelReset()
* src/util.c: Don't drop capabilities until after the PID file has
been written. Kill off child if writing the PID file fails
* src/qemu_driver.c: Remove bogus trailing '/' in state dir
* esx/esx_driver.c: add some documentation about the CPU scheduler
parameters and remove some old, unnecessary compensation code, since
virsh uses the proposed parameter types now.
* src/qemu_driver.c: fix qemudOpenMonitorUnix() to retry on ENOENT
instead of EACCES which is the error one receive when the socket
error hasn't shown up yet
polkit was disabled by default for a reason - because we selectively
enable it on newer fedoras rather than disable it on older fedoras
Same fix needed for netcf
It's not needed at build time
Removed in Fedora by:
* Fri Jun 5 2009 Mark McLoughlin <markmc@redhat.com> - 0.6.4-2.fc12
- Remove the qemu BuildRequires
Disabled on < f12 for now until netcf is in Fedora updates
BuildRequires netcf if enabled, pass --without-netcf if its disabled
* libvirt.spec.in: enabled netcf by default
In order to hotplug a network/bridge backed NIC, we need to first create
the tap file descriptor, add the tap interface to the bridge and then
pass the file descriptor to the qemu process using the 'getfd' monitor
command.
Once the tapfd has been accepted, we create the network backend using
host_net_add, supplying the name assigned to the tapfd. If this fails,
we need to close the tapfd in qemu using the 'closefd' monitor command.
If the version of qemu does not support the getfd/closefd monitor
commands we detect "unknown command" in the getfd reply and fail the
attach operation.
* src/qemu_driver.c: add support for tapfd based hotplug in
qemudDomainAttachNetDevice()
Add qemudMonitorCommandWithFd() which allows a file descriptor to be
sent to qemu over a unix monitor socket using SCM_RIGHTS. See the
unix(7) and cmsg(3) man pages.
* src/qemu_conf.c: add a scm_fd param to qemudMonitorCommandExtra(),
add qemudMonitorCommandWithFd(), implement SCM_RIGHTS support in
qemudMonitorSendUnix()
Switch from using write() to using sendmsg() on QEMU's monitor socket
so that we can add support for SCM_RIGHTS.
* src/qemu_driver.c: add sendmsg() based qemudMonitorSendUnix() and use
it when the monitor fd is a unix socket
Add a little helper function to write the monitor command followed by
carriage return in a single write.
This doesn't make any real difference, but allows us to more easily
switch to using sendmsg() when using the monitor over a unix socket.
* src/qemu_conf.c: split qemudMonitorSend() out
In subsequent patches we're going to have a file descriptor to close
too, so centralize the error handling cleanups to make things easier.
* src/qemu_conf.c: in qemudDomainAttachNetDevice() consolidate the
error handling cleanups together
With hotplug, we're going to want to pass a tapfd name rather than an
actual file descriptor, so prepare the way by passing a string tapfd to
qemuBuildHostNetStr().
* src/qemu_conf.h: qemuBuildHostNetStr() takes a string tapfd now
* src/qemu_conf.c: pass qemuBuildHostNetStr() a string rather than an
actual file descriptor
* src/qemu_driver.c: update qemudDomainAttachNetDevice() for change
* src/qemu_conf.h: export qemudNetworkIfaceConnect()
* src/qemu_conf.c: move vnet_hdr logic into qemudNetworkIfaceConnect()
since we need it for hotplug too
By probing for qemu machine types, we increased the time of a
GetCapabilities call from 100us to a whopping 60ms.
This patch takes the approach of only probing for machine types
when the mtime of the emulator binary changed since the last time
the capabilities were generated.
* src/capabilities.h: cache the emulator binary mtime
* src/qemu_conf.c: add qemudGetOldMachines() to copy the machine
types from the old caps struct if the mtime for the binary hasn't
changed
* src/qemu_conf.h, src/qemu_driver.c: pass the old caps pointer to
qemudCapsInit()
e.g. <machine canonical='pc'>pc-0.11</machine>
* src/capabilities.c: output the canonical machine names in the
capabilities output, if available
* docs/schemas/capabilities.rng: add the new attribute
Not all possible emulators are actually in the capabilities, so if we
don't find the supplied emulator we should probe it directly for machine
types.
* src/qemu_driver.c: add qemudCanonicalizeMachineDirect() to directly
probe an emulator for the canonical machine type
In qemu-0.11 there is a 'pc-0.10' machine type which allows you to run
guests with a machine which is compatible with the pc machine in
qemu-0.10 - e.g. using the original PCI class for virtio-blk and
virtio-console and disabling MSI support in virtio-net. The idea here
is that we don't want to suprise guests by changing the hardware when
qemu is updated.
I've just posted some patches for qemu-0.11 which allows libvirt to
canonicalize the 'pc' machine alias to the latest machine version.
This patches makes us use that so that when a guest is configured to
use the 'pc' machine type, we resolve that to 'pc-0.11' machine and
save that in the guest XML.

https://fedoraproject.org/wiki/Features/KVM_Stable_Guest_ABI
* src/qemu_conf.c: add qemudCanonicalizeMachine() to canonicalize
the machine type according to the machine aliases in capabilities
* src/qemu_driver.c: parse aliases in qemudParseMachineTypesStr()
A subsequent commit will add a "canonical" field to this structure,
this patch basically just prepares the way for that.
The new type is added, along with virCapabilitiesAlloc/FreeMachines()
helpers and a whole bunch of code to make the transition.
One quirk is that virCapabilitiesAddGuestDomain() and
virCapabilitiesAddGuest() take ownership of the machine list rather
than duping it. This makes sense to avoid needless copying.
* src/capabilities.h: add the virCapsGuestMachine struct and use it
in virCapsGuestDomainInfo, add prototypes for new functions and
update the AddGuest() prototypes
* src/capabilities.c: add code for allocating and freeing the new
type, change the machines parameter to AddGuest() etc.
* src/libvirt_private.syms: export the new helpers
* src/qemu_conf.c: update all the machine type code to use the new
struct
* src/xen_internal.c: ditto
* tests/testutilsqemu.c: ditto
