Adds a "ram" attribute globally to the video.model element, that changes the resulting qemu command line only if video.type == "qxl". <video> <model type='qxl' ram='65536' vram='65536' heads='1'/> </video> That attribute gets a default value of 64*1024. The schema is unchanged for other video element types. The resulting qemu command line change is the addition of -global qxl-vga.ram_size=<ram>*1024 or -global qxl.ram_size=<ram>*1024 For the main and secondary qxl devices respectively. The default for the qxl ram bar is 64*1024 kilobytes (the same as the default qxl vram bar size).

The SCLP console is the native console type for s390 and is preferred over the virtio console as it doesn't require special drivers and is more efficient. Recent versions of QEMU come with SCLP support which is hereby enabled. The new target types 'sclp' and 'sclplm' can be used to specify a SCLP console.

This introduces new XML tag "sgio" for disk, its valid values are "filtered" and "unfiltered", setting it as "filtered" will set the disk's unpriv_sgio to 0, and "unfiltered" to set it as 1, which allows the unprivileged SG_IO commands.

The <hostdev> device type has long had a redundant "mode" attribute, which has always been "subsys". This finally introduces a new mode "capabilities", which will be used by the LXC driver for device assignment. Since container based virtualization uses a single kernel, the idea of assigning physical PCI devices doesn't make sense. It is still reasonable to assign USB devices, but for assigning arbitrary nodes in /dev, the new 'capabilities' mode is to be used. The first capability support is 'storage', which is for assignment of block devices. Functionally this is really pretty similar to the <disk> support. The only difference is the device node name is identical in both host and container namespaces. <hostdev mode='capabilities' type='storage'> <source> <block>/dev/sdf1</block> </source> </hostdev> The second capability support is 'misc', which is for assignment of character devices. There is no existing parallel to this. Again the device node is the same inside & outside the container. <hostdev mode='capabilities' type='misc'> <source> <char>/dev/input/event3</char> </source> </hostdev> The reason for keeping the char & storage devices separate in the domain XML, is to mirror the split in the node device XML. NB the node device XML does not yet report character devices, but that's another new patch to come Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

If there are multiple video devices primary = 'yes' marks this video device as the primary one. The rest are secondary video devices. No more than one could be mark as primary. If none of them has primary attribute, the first one will be the primary by default like what it was. The reason of this changing is that for qemu, only one primary video device is permitted which can be of any type. For secondary video devices, only qxl is allowd. Primary attribute removes the restriction that the first have to be the primary one. We always put the primary video device into the first position of video device structure array after parsing.

This is however supported only on domain interfaces with type='network'. Moreover, target network needs to have at least inbound QoS set. This is required by hierarchical traffic shaping. From now on, the required attribute for <inbound/> is either 'average' (old) or 'floor' (new). This new attribute can be used just for interfaces type of network (<interface type='network'/>) currently.

The DHCPv6 support includes IPV6 dhcp-range and dhcp-host for one IPv6 subnetwork on one interface. This support will only work if dnsmasq version >= 2.64; otherwise an error occurs if dhcp-range or dhcp-host is specified for an IPv6 address. Essentially, this change provides the same DHCP support for IPv6 that has been available for IPv4. With dnsmasq >= 2.64, support for the RA service is also now provided by dnsmasq (radvd is no longer used/started). (Although at least one version of dnsmasq prior to 2.64 "supported" IPv6 Router Advertisement, there were bugs (fixed in 2.64) that rendered it unusable.) Documentation and the network schema has been updated to reflect the new support.

This patch adds the capability for virtual guests to do IPv6 communication via a virtual network interface with no IPv6 (gateway) addresses specified. This capability has always been enabled by default for IPv4, but disabled for IPv6 for security concerns, and because it requires the ip6tables command to be operational (which isn't the case on a system with the ipv6 module completely disabled). This patch adds a new attribute "ipv6" at the toplevel of a <network> object. If ipv6='yes', the extra ip6tables rules required to permite inter-guest communications are added when the network is started. If it is 'no', or not present, those rules will not be added; thus the default behavior doesn't change, so there should be no compatibility issues with any existing installations. Note that virtual guests cannot communication with the virtualization host via this interface, because the following kernel tunable has been set: net.ipv6.conf.<bridge_interface_name>.disable_ipv6 = 1 This assures that the bridge interface will not have an IPv6 link-local (fe80::) address. To control this behavior so that it is not enabled by default, the parameter ipv6='yes' on the <network> statement has been added. Documentation related to this patch has been updated. The network schema has also been updated.

This patch introduces the RNG schema and updates necessary data strucutures to allow various hypervisors to make use of Gluster protocol as one of the supported network disk backend. Next patch will add support to make use of this feature in Qemu since it now supports Gluster protocol as one of the network based storage backend. Two new optional attributes for <host> element are introduced - 'transport' and 'socket'. Valid transport values are tcp, unix or rdma. If none specified, tcp is assumed. If transport is unix, socket specifies path to unix socket. This patch allows users to specify disks on gluster backends like this: <disk type='network' device='disk'> <driver name='qemu' type='raw'/> <source protocol='gluster' name='Volume1/image'> <host name='example.org' port='6000' transport='tcp'/> </source> <target dev='vda' bus='virtio'/> </disk> <disk type='network' device='disk'> <driver name='qemu' type='raw'/> <source protocol='gluster' name='Volume2/image'> <host transport='unix' socket='/path/to/sock'/> </source> <target dev='vdb' bus='virtio'/> </disk> Signed-off-by: NHarsh Prateek Bora <harsh@linux.vnet.ibm.com>

Each <domainsnapshot> can now contain an optional <memory> element that describes how the VM state was handled, similar to disk snapshots. The new element will always appear in output; for back-compat, an input that lacks the element will assume 'no' or 'internal' according to the domain state. Along with this change, it is now possible to pass <disks> in the XML for an offline snapshot; this also needs to be wired up in a future patch, to make it possible to choose internal vs. external on a per-disk basis for each disk in an offline domain. At that point, using the --disk-only flag for an offline domain will be able to work. For some examples below, remember that qemu supports the following snapshot actions: qemu-img: offline external and internal disk savevm: online internal VM and disk migrate: online external VM transaction: online external disk ===== <domainsnapshot> <memory snapshot='no'/> ... </domainsnapshot> implies that there is no VM state saved (mandatory for offline and disk-only snapshots, not possible otherwise); using qemu-img for offline domains and transaction for online. ===== <domainsnapshot> <memory snapshot='internal'/> ... </domainsnapshot> state is saved inside one of the disks (as in qemu's 'savevm' system checkpoint implementation). If needed in the future, we can also add an attribute pointing out _which_ disk saved the internal state; maybe disk='vda'. ===== <domainsnapshot> <memory snapshot='external' file='/path/to/state'/> ... </domainsnapshot> This is not wired up yet, but future patches will allow this to control a combination of 'virsh save /path/to/state' plus disk snapshots from the same point in time. ===== So for 1.0.1 (and later, as needed), I plan to implement this table of combinations, with '*' designating new code and '+' designating existing code reached through new combinations of xml and/or the existing DISK_ONLY flag: domain memory disk disk-only | result ----------------------------------------- offline omit omit any | memory=no disk=int, via qemu-img offline no omit any |+memory=no disk=int, via qemu-img offline omit/no no any | invalid combination (nothing to snapshot) offline omit/no int any |+memory=no disk=int, via qemu-img offline omit/no ext any |*memory=no disk=ext, via qemu-img offline int/ext any any | invalid combination (no memory to save) online omit omit off | memory=int disk=int, via savevm online omit omit on | memory=no disk=default, via transaction online omit no/ext off | unsupported for now online omit no on | invalid combination (nothing to snapshot) online omit ext on | memory=no disk=ext, via transaction online omit int off |+memory=int disk=int, via savevm online omit int on | unsupported for now online no omit any |+memory=no disk=default, via transaction online no no any | invalid combination (nothing to snapshot) online no int any | unsupported for now online no ext any |+memory=no disk=ext, via transaction online int/ext any on | invalid combination (disk-only vs. memory) online int omit off |+memory=int disk=int, via savevm online int no/ext off | unsupported for now online int int off |+memory=int disk=int, via savevm online ext omit off |*memory=ext disk=default, via migrate+trans online ext no off |+memory=ext disk=no, via migrate online ext int off | unsupported for now online ext ext off |*memory=ext disk=ext, via migrate+transaction * docs/schemas/domainsnapshot.rng (memory): New RNG element. * docs/formatsnapshot.html.in: Document it. * src/conf/snapshot_conf.h (virDomainSnapshotDef): New fields. * src/conf/domain_conf.c (virDomainSnapshotDefFree) (virDomainSnapshotDefParseString, virDomainSnapshotDefFormat): Manage new fields. * tests/domainsnapshotxml2xmltest.c: New test. * tests/domainsnapshotxml2xmlin/*.xml: Update existing tests. * tests/domainsnapshotxml2xmlout/*.xml: Likewise.

At one point, the code passed through arbitrary strings for file formats, which supposedly lets qemu handle a new file type even before libvirt has been taught to handle it. However, to properly label files, libvirt has to learn the file type anyway, so we might as well make our life easier by only accepting file types that we are prepared to handle. This patch lets the RNG validation ensure that only known strings are let through. * docs/schemas/domaincommon.rng (driverFormat): Limit to list of supported strings. * docs/schemas/domainsnapshot.rng (driver): Likewise.

The following config elements now support a <vlan> subelements: within a domain: <interface>, and the <actual> subelement of <interface> within a network: the toplevel, as well as any <portgroup> Each vlan element must have one or more <tag id='n'/> subelements. If there is more than one tag, it is assumed that vlan trunking is being requested. If trunking is required with only a single tag, the attribute "trunk='yes'" should be added to the toplevel <vlan> element. Some examples: <interface type='hostdev'/> <vlan> <tag id='42'/> </vlan> <mac address='52:54:00:12:34:56'/> ... </interface> <network> <name>vlan-net</name> <vlan trunk='yes'> <tag id='30'/> </vlan> <virtualport type='openvswitch'/> </network> <interface type='network'/> <source network='vlan-net'/> ... </interface> <network> <name>trunk-vlan</name> <vlan> <tag id='42'/> <tag id='43'/> </vlan> ... </network> <network> <name>multi</name> ... <portgroup name='production'/> <vlan> <tag id='42'/> </vlan> </portgroup> <portgroup name='test'/> <vlan> <tag id='666'/> </vlan> </portgroup> </network> <interface type='network'/> <source network='multi' portgroup='test'/> ... </interface> IMPORTANT NOTE: As of this patch there is no backend support for the vlan element for *any* network device type. When support is added in later patches, it will only be for those select network types that support setting up a vlan on the host side, without the guest's involvement. (For example, it will be possible to configure a vlan for a guest connected to an openvswitch bridge, but it won't be possible to do that for one that is connected to a standard Linux host bridge.)
