Introduce new members in the virMacAddr 'class' - virMacAddrSet: set virMacAddr from a virMacAddr - virMacAddrSetRaw: setting virMacAddr from raw 6 byte MAC address buffer - virMacAddrGetRaw: writing virMacAddr into raw 6 byte MAC address buffer - virMacAddrCmp: comparing two virMacAddr - virMacAddrCmpRaw: comparing a virMacAddr with a raw 6 byte MAC address buffer then replace raw MAC addresses by replacing - 'unsigned char *' with virMacAddrPtr - 'unsigned char ... [VIR_MAC_BUFLEN]' with virMacAddr and introduce usage of above functions where necessary.

Right now, the only way to get at the contents of a virBuffer is to destroy it. But there are cases in my upcoming patches where peeking at the contents makes life easier.

The goal of this patch is to prepare for support for multiple IP addresses per interface in the DHCP snooping code. Move the code for the IP address map that maps interface names to IP addresses into their own file. Rename the functions on the way but otherwise leave the code as-is. Initialize this new layer separately before dependent layers (iplearning, dhcpsnooping) and shut it down after them.

When the last reference to a virConnectPtr is released by libvirtd, it was possible for a deadlock to occur in the virDomainEventState functions. The virDomainEventStatePtr holds a reference on virConnectPtr for each registered callback. When removing a callback, the virUnrefConnect function is run. If this causes the last reference on the virConnectPtr to be released, then virReleaseConnect can be run, which in turns calls qemudClose. This function has a call to virDomainEventStateDeregisterConn which is intended to remove all callbacks associated with the virConnectPtr instance. This will try to grab a lock on virDomainEventState but this lock is already held. Deadlock ensues Thread 1 (Thread 0x7fcbb526a840 (LWP 23185)): Since each callback associated with a virConnectPtr holds a reference on virConnectPtr, it is impossible for the qemudClose method to be invoked while any callbacks are still registered. Thus the call to virDomainEventStateDeregisterConn must in fact be a no-op. Thus it is possible to just remove all trace of virDomainEventStateDeregisterConn and avoid the deadlock. * src/conf/domain_event.c, src/conf/domain_event.h, src/libvirt_private.syms: Delete virDomainEventStateDeregisterConn * src/libxl/libxl_driver.c, src/lxc/lxc_driver.c, src/qemu/qemu_driver.c, src/uml/uml_driver.c: Remove calls to virDomainEventStateDeregisterConn

Though numad will manage the memory allocation of task dynamically, it wants management application (libvirt) to pre-set the memory policy according to the advisory nodeset returned from querying numad, (just like pre-bind CPU nodeset for domain process), and thus the performance could benefit much more from it. This patch introduces new XML tag 'placement', value 'auto' indicates whether to set the memory policy with the advisory nodeset from numad, and its value defaults to the value of <vcpu> placement, or 'static' if 'nodeset' is specified. Example of the new XML tag's usage: <numatune> <memory placement='auto' mode='interleave'/> </numatune> Just like what current "numatune" does, the 'auto' numa memory policy setting uses libnuma's API too. If <vcpu> "placement" is "auto", and <numatune> is not specified explicitly, a default <numatume> will be added with "placement" set as "auto", and "mode" set as "strict". The following XML can now fully drive numad: 1) <vcpu> placement is 'auto', no <numatune> is specified. <vcpu placement='auto'>10</vcpu> 2) <vcpu> placement is 'auto', no 'placement' is specified for <numatune>. <vcpu placement='auto'>10</vcpu> <numatune> <memory mode='interleave'/> </numatune> And it's also able to control the CPU placement and memory policy independently. e.g. 1) <vcpu> placement is 'auto', and <numatune> placement is 'static' <vcpu placement='auto'>10</vcpu> <numatune> <memory mode='strict' nodeset='0-10,^7'/> </numatune> 2) <vcpu> placement is 'static', and <numatune> placement is 'auto' <vcpu placement='static' cpuset='0-24,^12'>10</vcpu> <numatune> <memory mode='interleave' placement='auto'/> </numatume> A follow up patch will change the XML formatting codes to always output 'placement' for <vcpu>, even it's 'static'.

This value will be needed to set the src_pid when sending netlink messages to lldpad. It is part of the solution to: https://bugzilla.redhat.com/show_bug.cgi?id=816465 Note that libnl's port generation algorithm guarantees that the nl_socket_get_local_port() will always be > 0 (since it is "getpid() + (n << 22>" where n is always < 1024), so it is okay to cast the uint32_t to int (thus allowing us to use -1 as an error sentinel).

Note that this patch by itself breaks communication between lldpad and libvirtd, so the other 3 patches in the series must be applied at the same time as this patch.

DBus connection. The HAL device code further requires that the DBus connection is integrated with the event loop and provides such glue logic itself. The forthcoming FirewallD integration also requires a dbus connection with event loop integration. Thus we need to pull the current event loop glue out of the HAL driver. Thus we create src/util/virdbus.{c,h} files. This contains just one method virDBusGetSystemBus() which obtains a handle to the single shared system bus instance, with event glue automagically setup.

Since Xen 3.1 the clock=variable semantic is supported. In addition to qemu/kvm Xen also knows about a variant where the offset is relative to 'localtime' instead of 'utc'. Extends the libvirt structure with a flag 'basis' to specify, if the offset is relative to 'localtime' or 'utc'. Extends the libvirt structure with a flag 'reset' to force the reset behaviour of 'localtime' and 'utc'; this is needed for backward compatibility with previous versions of libvirt, since they report incorrect XML. Adapt the only user 'qemu' to the new name. Extend the RelaxNG schema accordingly. Document the new 'basis' attribute in the HTML documentation. Adapt test for the new attribute.

A few times libvirt users manually setting mac addresses have complained of a networking failure that ends up being due to a multicast mac address being used for a guest interface. This patch prevents that by logging an error and failing if a multicast mac address is encountered in each of the three following cases: 1) domain xml <interface> mac address. 2) network xml bridge mac address. 3) network xml dhcp/host mac address. There are several other places where a mac address can be input that aren't controlled in this manner because failure to do so has no consequences (e.g., if the address will be used to search through existing interfaces for a match). The RNG has been updated to add multiMacAddr and uniMacAddr along with the existing macAddr, and macAddr was switched to uniMacAddr where appropriate.

numad is an user-level daemon that monitors NUMA topology and processes resource consumption to facilitate good NUMA resource alignment of applications/virtual machines to improve performance and minimize cost of remote memory latencies. It provides a pre-placement advisory interface, so significant processes can be pre-bound to nodes with sufficient available resources. More details: http://fedoraproject.org/wiki/Features/numad "numad -w ncpus:memory_amount" is the advisory interface numad provides currently. This patch add the support by introducing a new XML attribute for <vcpu>. e.g. <vcpu placement="auto">4</vcpu> <vcpu placement="static" cpuset="1-10^6">4</vcpu> The returned advisory nodeset from numad will be printed in domain's dumped XML. e.g. <vcpu placement="auto" cpuset="1-10^6">4</vcpu> If placement is "auto", the number of vcpus and the current memory amount specified in domain XML will be used for numad command line (numad uses MB for memory amount): numad -w $num_of_vcpus:$current_memory_amount / 1024 The advisory nodeset returned from numad will be used to set domain process CPU affinity then. (e.g. qemuProcessInitCpuAffinity). If the user specifies both CPU affinity policy (e.g. (<vcpu cpuset="1-10,^7,^8">4</vcpu>) and placement == "auto" the specified CPU affinity will be overridden. Only QEMU/KVM drivers support it now. See docs update in patch for more details.
