If the ipv6 kernel module is not loaded, then we get this when starting
a virtual network:
libvir: Network Config error :
cannot enable /proc/sys/net/ipv6/conf/virbr0/disable_ipv6:
No such file or directory
If disable_ipv6 is not present, we should just merrily continue on our
way.
* src/network_driver.c: make networkDisableIPV6() not fail if the kernel
has no ipv6 support
If we're running qemu unprivileged, we need to chown any supplied kernel
or initrd before spawning it.
* src/qemu_driver.c: rename qemuDomainSetDiskOwnership() to
qemuDomainSetFileOwnership(), pass it a path string instead of a disk
definition and use it for chowning the kernel/initrd in
qemuDomainSetAllDeviceOwnership()
While trying to remove uses of unsafe strncpy in the tree, I came
across a couple of usages in the ESX driver. To my eyes, the snprintf
replacements do the same thing in less code, and are also safer.

Fix up qemudDomainMigratePrepare2 to use virGetHostname instead of

there was a latent bug in the handling that could cause a buffer overflow

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.
See also:
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
Currently we hardcode the QEMU machine types. We should really just
parse the output of 'qemu -M ?' so the lists don't get out of sync.
xenner doesn't support '-M ?', so we still need to hardcode that.
The horrible (const char *const *) is removed in a subsequent patch.
* src/qemu_conf.c: kill the arch_info*machines tables, retain the
hardcoded xenner machine type, add qemudProbeMachineTypes() to
run and parse 'qemu -M ?' and use it in qemudCapsInitGuest()

use 'gnu_printf' with GCC >= 4.4 to get correct compiler
checking of printf format specifiers.

If the qemu binary supports "-no-kvm" and/or "-no-kqemu", they should
always be added for plain "qemu" domains. Previously, we omitted them
whenever the host and guest architectures implied that they would be
disabled automatically, but that logic was flawed in some cases
(such as i686 and x86_64).
* src/qemu_conf.c: fix the conditions for adding "-no-kvm" and/or "-no-kqemu"

qemu network devices are hot-unplugged in two stages - first the PCI NIC
is removed using 'pci_del <pci_addr>' and then the backend is removed
using 'host_net_remove <vlan> <name>'.
In order to perform these operations we need to have retained the
PCI address, backend name and vlan number.
* src/qemu_driver.c: add qemudDomainDetachNetDevice()
When we pci_add a NIC, we need to retain the PCI address assigned by
qemu for using during detach.
* src/qemu_driver.c: use qemudParsePciAddReply() to pull the PCI
address from the pci_add reply
* src/domain_conf.c: handle storing and parsing the PCI address in the
domain state XML file
The current code for parsing pci_add replies ignores the the domain and
bus numbers. Re-write the code to rectify that.
Also, since pci_add is used for NIC hotplug as well ask disk hotplug,
re-factor the code into a separate function.
* src/qemu_driver.c: add qemudParsePciAddReply() function which can
handle parsing domain and bus numbers
If we fail to pci_add a NIC, we should remove the network backend and
leave things the way we found them. To do that, we pre-allocate a
host_net_remove monitor command and issue that if the pci_add fails.
If the remove fails, we just log a warning.
We can only do this if we have a name for the network backend and
we know the vlan number its associated with.
* src/qemu_driver.c: host_net_remove the network backend if the
pci_add fails
Implement basic NIC hotplug support using the 'host_net_add' and
'pci_add' qemu monitor commands.
For now, we don't support 'bridge' or 'network' types.
Also, if pci_add fails, we currently fail to remove the backend
which we added.
Finally, NIC hot-unplug support is missing.
* src/qemu_driver.c: add qemudDomainAttachNetDevice()
* src/qemu_conf.[ch]: export qemuBuildNicStr(), qemuBuildHostNetStr()
and qemuAssignNames()
* src/libvirt_private.syms: export virDomainNetTypeToString()
qemudDomainChangeEjectableMedia() currently extracts the qemu command
line flags, but other device attaching code might need it, so move
the qemudExtractVersionInfo() call up a frame.
* src/qemu_driver.c: move the qemudExtractVersionInfo() call from
qemudDomainChangeEjectableMedia() to qemudDomainAttachDevice()
Currently, an interface's vlan number corresponds to its index in
the table of network interfaces. That is no longer true when we
allow devices to be removed.
To fix this, we store the vlan number in the domain's state XML
so that it survives libvirtd restarts.
* src/domain_conf.h: add vlan number to virDomainNetDef
* src/domain_conf.c: store it in XML as <state vlan='N'/>, defaulting
to -1 if this is state saved by a previous version of libvirt
* src/qemu_conf.c: assign vlan numbers before starting qemu
The qemu driver needs to assign and keep track of identifiers for
network devices so that it can remove them. We need to keep this state
across libvirtd restarts, but it's not configuration that needs to
be kept across guest restarts.
* src/domain_conf.c: parse and format <state nic="foo" hostnet="bar"/>
We need these so that we can remove the devices via the monitor.
* src/domain_conf.h: add nic_name and hostnet_name to virDomainNetDef
* src/domain_conf.c: free nic_name and hostnet_name
* src/qemu_conf.c: add qemuAssignNetNames(), use it if qemu has
support for the param and pass the names on the command line
* tests/qemuxml2argv*: add a test for this
Add QEMUD_CMD_FLAG_NET_NAME to indicate that '-net ...,name=foo' is
supported and QEMUD_CMD_FLAG_HOST_NET_ADD to indicate that the
'host_net_add' monitor command is available.
Set both these flags if the qemu version is greater than 0.10.0.
Checking via the '-help' output would not work for the monitor command
and even for the command line arg, it would be quite fragile.
* src/qemu_conf.h: add new flags as aliases of QEMUD_CMD_FLAG_0_10
* src/qemu_conf.c: set QEMUD_CMD_FLAG_0_10 for versions >= 0.10.0
* tests/qemuhelptest.c: set QEMUD_CMD_FLAG_0_10 for the appropriate
qemu versions
Re-factor this code so that it can be used for NIC hotplug
too. The awkward prefix and type_sep arguments are needed to
allow us to do "host_net_add tap vlan=..."
* src/qemu_conf.c: factor the net backend string formatting
code into its own function
Re-factor this code so that it can be used for NIC hotplug
too. The awkward arguments are needed to allow use to do
"pci_add auto nic macaddr=..."
* src/qemu_conf.c: factor the nic string formatting code into
its own function
When we hot-plug a disk device into a qemu guest, we need to retain its
PCI address so that it can be removed again later. Currently, we do
retain the slot number, but not across libvirtd restarts.
Add <state devaddr="xxxx:xx:xx"/> to the disk device XML config when the
VIR_DOMAIN_XML_INTERNAL_STATUS flag is used. We still don't parse the
domain and bus number, but the format allows us to do that in future.
* src/domain_conf.h: replace slotnum with pci_addr struct, add helper
for testing whether the address is valid
* src/domain_conf.c: handle formatting and parsing the address
* src/qemu_driver.c: store the parsed slot number as a full PCI address,
and use this address with the pci_del monitor command
* src/vbox/vbox_tmpl.c: we're debug printing slotnum here even though
it can never be set, just delete it
We need to store things like device names and PCI slot numbers in the
qemu domain state file so that we don't lose that information on
libvirtd restart. Add a flag to indicate that this information should
be parsed or formatted.
Make bit 16 and above of the flags bitmask for internal use only and
consume the first bit for this new status flag.
* include/libvirt/libvirt.h: add VIR_DOMAIN_XML_FLAGS_MASK
* src/libvirt.c: reject private flags in virDomainGetXMLDesc()
* src/domain_conf.h: add VIR_DOMAIN_XML_INTERNAL_STATUS
* src/domain_conf.c: pass the flag from virDomainObjParseXML() and
virDomainSaveStatus
* src/libvirt.c: activate the interface drivers
* po/POTFILES.in: add the netcf driver as a source of localization strings

* src/libvirt_private.syms: export needed symbols internally
MAC address of a particular interface may change over time, and the
reduced virInterface object (which contains just name and mac) needs
to reflect these changes. Since we can't modify the mac address of an
existing virInterface (some other thread may currently be using it) we
just create a new virInterface, and let the old one die a dignified
death when its refct goes to 0.
* src/datatypes.c: fix the matching and lifetime of virInterface object
accordingly
* include/libvirt/virterror.h src/virterror.c: if a driver's
virInterfaceLookupByMACString() function finds more than one interface
with the desired MAC Address, this new error is raised.
* src/virsh.c: add a number of interface related commands:
iface-list, iface-name, iface-mac, iface-dumpxml, iface-define,
iface-undefine, iface-edit, iface-start and iface-destroy
Unlike the pty monitor (which we know exists since we scrape its path from
stdout), we have no way of knowing that the unix monitor socket should exist/
be initialized. As a result, some of my KVM guests randomly fail to start on
F10 host.
Try to open the unix socket in a 3 second timeout loop. Ignore EACCES (path
does not exist if a first time run) and ECONNREFUSED (leftover socket from
a previous run hasn't been removed yet). Fixes things for me.
Have storage building functions be definitions of
virStorageBackendBuildVolFrom: we will need to do this in the future anyways
if we ever support the flags attribute.
Break out separate functions for
- Determining the supported '*-img' tool,
- The tool's associated create function,
- Desired function for cloning (CreateXMLFrom).
This will be eventually used to unify cloning across all backends.
Currently, if no format is specified for a new disk volume, we pass the
invalid value "none" as the FS type to 'parted mkpart'.
There doesn't seem to be a way to have parted not format the drive, so
just default to using 'ext2' in this case: this shouldn't cause any harm,
since we are creating a new partition in the first place.

Splits up the 'call' method moving generic IO code out into
separate method to allow it to be easily reused for sending

* src/remote_internal.c: Split 'call' into two methods, the first

* src/remote_internal.c: Rename processCallRecvMsg to

The 'remote_message_header' struct has a mis-leadingly named
field 'direction'. It is really a reflection of the type of
message, and some types can be sent in either direction. Thus
the field is more accurately named 'type'. No function change.
* qemud/remote_protocol.x: Rename 'direction' to 'type' in

* qemud/remote_protocol.c, qemud/remote_protocol.h: Regenerate
* qemud/remote.c, qemud/dispatch.c, src/remote_internal.c
Update to reflect rename of 'direction' to 'type'
The naming convention for structs used in the RPC layer is for
incoming requests to be called XXXX_args, and the associated
outgoing reply to be called XXXX_ret. Asynchronously emitted
messages (eg events) are re-using the XXXX_ret naming scheme.
This patch changes that such that async messages are XXXX_msg,
and stops adding entries for them in the dispatch table, avoiding
the need for a dummy no-op implementation.
* qemud/remote.c: Remove dummy remoteDispatchDomainEvent, no

If using a custom test driver, storage pool file parsing was broken, and
storage volume parsing was never implemented. Fix these issues, and add
some examples in docs/
The storage driver arranges its parsing routines in a way that make them
difficult to use in the test driver for non-default file parsing. This
refactoring moves things to be consistent with the way domain_conf and
network_conf do things.
If specifying a custom test driver, virtual networks were not 'activated'
on driver init. This differs from the behavior of domains and storage pools,
so fix it. Also improve a couple error messages in that area.
virEnumFromString doesn't check for a NULL string, and will segfault if
passed one. Lots of calling code protects against this, but at least
/pool/@type parsing does not.
CreateXMLFrom changes accidentally caused all raw volume creation to be
fully allocated (as though allocation == capacity). Fix this.
Also force CreateXMLFrom to maintain the previous behavior: sparseness
should still be maintained since we search for holes when copying, and the
clone behavior hasn't been tested with anything but the broken behavior.
Rather than numerous instances of:
emulator = vm->def->emulator;
if (!emulator)
emulator = virDomainDefDefaultEmulator(conn, vm->def, driver->caps);
if (!emulator)
return -1;
Set this value at XML parse time in the domain config, so we can depend on
it for all future emulator accesses. There were unchecked accesses in the
qemu driver that were tripping up on this if no emulator was specified in
the XML, see:
http://www.redhat.com/archives/libvir-list/2008-October/msg00602.html
Certain drivers always need an 'emulator' specified in the XML (qemu and lxc
at least). Store this info in capabilities.
We will eventually use this to move default emulator handling out of
drivers and into domain_conf.*

The KVM version string can be one of the following:
- qemu-kvm-x.y.z in stable releases
- kvm-XX for kvm versions up to kvm-85
- qemu-kvm-devel-XX for kvm version kvm-86 and later
There are only a few of places where we need to detect
differences between KVM versions based on 0.9.1:
1) VNET_HDR introduced in kvm-74
2) -incoming tcp introduced in kvm-79
3) -incoming exec introduced in kvm-80
4) -incoming stdio in all earlier kvm versions
With qemu-kvm-0.10.x, we can now assume that (1) is available
if it's a KVM release, (2) and (3) is always available and
(4) is never available.
So, from now on we should only need to check the qemu version
number and the "is_kvm" flag for detecting feature availability.
We only need the KVM version number for older releases.
Signed-off-by: Mark McLoughlin <markmc@redhat.com>
This patch is purely re-factoring without any functional changes
to make way for the next patch.
The main thing achieved by the refactoring is that we now have
easier access to the parenthesised string that KVM folks seem
to delight in changing.

If two virtual networks have the same hardcoded bridge device (which
prevents them from being active simultaneously) we still want to define
them at daemon startup, so the user has a fighting chance of correcting
the XML error.
Add an extra flag to SetBridge to avoid reporting an error if there is
a bridge collision, and use this when loading network configs at startup.
This regressed via commit 4c3f3b4d.
Parse the command line output a bit earlier so we have a better chance
of reporting the full error output on failure.
I hit this when QEMU would try to boot an invalid kernel (virtinst bug).
There is different spacing when listing active vs. inactive networks. Ex:
Name State Autostart
-----------------------------------------
default active yes
xxxxxx inactive no

There is some funkiness here, since we are either dealing with 2 different
pools (which means validation x 2) or the same pool, where we have to be
careful not to deadlock.
The cap_lost and prop_modified callbacks could deadlock if an existing
device needed to be refreshed, since dev_create expects the driver to
be unlocked.

Improves readability, particularly wrt the pending CreateFromXML changes.
This will also help implementing File->Block volume creation in the future,
since some of this code will need to be moved to a backend agnostic file.
vol-clone is a convenience function, requiring only a volume to clone and a
new name.
vol-create-from is a direct mapping to the public API, which allows cloning
across pools, converting between formats, etc, but requires an xml file to be
passed
By checking the pid every retry period, we can quickly determine if
the process crashed at startup, rather than make the user wait for
the entire timeout (3 seconds).
virExec will write out the pid of the daemonized process only. Use this
in the QEMU driver, rather than QEMU's pidfile, so we can catch errors we
might miss if the emulator bails early.
Wraps __virExec with the VIR_EXEC_DAEMON flag. Waits on the intermediate
process to ensure we don't end up with any zombies, and differentiates between
original process errors and intermediate process errors.
