In case qemu supports -nodefconfig, libvirt adds uses it when launching new guests. Since this option may affect CPU models supported by qemu, we need to use it when probing for available models.

We previously assumed that if the -device option existed in qemu, that -nodefconfig would also exist. It turns out that isn't the case, as demonstrated by qemu-kvm-0.12.3 in Fedora 13. */src/qemu/qemu_conf.[hc] - add a new QEMUD_CMD_FLAG, set it via the help output, and check it before adding -nodefconfig to the qemu commandline.

Currently there is no way to opt out of libvirt dropping POSIX capabilities for qemu.

This patch parses the following two XML descriptions, one for 802.1Qbg and one for 802.1Qbh, and stores the data internally. The actual triggering of the switch setup protocol has not been implemented here but the relevant code to do that should go into the functions associatePortProfileId() and disassociatePortProfileId(). <interface type='direct'> <source dev='eth0.100' mode='vepa'/> <model type='virtio'/> <virtualport type='802.1Qbg'> <parameters managerid='12' typeid='0x123456' typeidversion='1' instanceid='fa9b7fff-b0a0-4893-8e0e-beef4ff18f8f'/> </virtualport> <filterref filter='clean-traffic'/> </interface> <interface type='direct'> <source dev='eth0.100' mode='vepa'/> <model type='virtio'/> <virtualport type='802.1Qbh'> <parameters profileid='my_profile'/> </virtualport> </interface> I'd suggest to use this patch as a base for triggering the setup protocol with the 802.1Qb{g|h} switch. Several rounds of changes were made to this patch. The following is a list of these changes. - Renamed structure virVirtualPortProfileDef to virVirtualPortProfileParams as per Daniel Berrange's request - Addressing Daniel Berrange's comments: - removing macvtap.h's dependency on domain_conf.h by moving the virVirtualPortProfileDef structure into macvtap.h and not passing virtDomainNetDefPtr to any functions in macvtap.c - Addressed most of Chris Wright's comments: - indicating error in case virtualport XML node cannot be parsed properly - parsing hex and decimal numbers using virStrToLong_ui() with parameter '0' for base - tgifname (target interface name) variable wasn't necessary to pass to openMacvtapTap function anymore - assigning the virtual port data structure to the virDomainNetDef only if it was previously parsed - make sure that the error code returned by openMacvtapTap() is a negative n in case the associatePortProfileId() function failed. - renaming vsi in the XML to virtualport - replace all occurrences of vsi in the source as well - removing mode and MAC address parameters from the functions that will communicate with the hareware diretctly or indirectly - moving the associate and disassociate functions to the end of the file for subsequent patches to easier make them generally available for export - passing the macvtap interface name rather than the link device since this otherwise gives funny side effects when using netlink messages where IFLA_IFNAME and IFLA_ADDRESS are specified and the link dev all of a sudden gets the MAC address of the macvtap interface. - Removing rc = -1 error indications in the case of 802.1Qbg|h setup in case we wanted to use hook scripts for the setup and so the setup doesn't fail here. - if instance ID UUID is not supplied it will automatically be generated - adapted schema to make instance ID UUID optional - added test case - parser and XML generator have been separated into their own functions so they can be re-used elsewhere (passthrough case for example) - Adapted XML parser and generator support the above shown type (802.1Qbg, 802.1Qbh). - Adapted schema to above XML - Adapted test XML to above XML - Passing through the VM's UUID which seems to be necessary for 802.1Qbh -- sorry no host UUID - adding virtual function ID to association function, in case it's necessary to use (for SR-IOV)

Currently all host audio backends are disabled if a VM is using VNC, in favor of the QEMU VNC audio extension. Unfortunately no released VNC client supports this extension, so users have no way of getting audio to work if using VNC.

The qemu driver contains a subtle race in the logic to find next available vnc port. Currently it iterates through all available ports and returns the first for which bind(2) succeeds. However it is possible that a previously issued port has not yet been bound by qemu, resulting in the same port used for a subsequent domain. This patch addresses the race by using a simple bitmap to "reserve" the ports allocated by libvirt. V2: - Put port bitmap in struct qemud_driver - Initialize bitmap in qemudStartup V3: - Check for failure of virBitmapGetBit - Additional check for port != -1 before calling virbitmapClearBit V4: - Check for failure of virBitmap{Set,Clear}Bit

Disk devices in QEMU have two parts, the guest device and the host backend driver. Historically these two parts have had the same "unique" name. With the switch to using -device though, they now have separate names.

The current way of assigning names to the host network backend and NIC device in QEMU was over complicated, by varying naming scheme based on the NIC model and backend type. This simplifies the naming to simply be 'net0' and 'hostnet0', allowing code to easily determine the host network name and vlan based off the primary device alias name 'net0'. This in turn allows removal of alot of QEMU specific code from the XML parser, and makes it easier to assign new unique names for NICs that are hotplugged * src/conf/domain_conf.c, src/conf/domain_conf.h: Remove hostnet_name and vlan fields from virNetworkDefPtr * src/qemu/qemu_conf.c, src/qemu/qemu_conf.h, src/qemu/qemu_driver.c: Use a single network alias naming scheme regardless of NIC type or backend type.

The current QEMU code allocates PCI addresses incrementally starting at 4. This is not satisfactory because the user may have given some addresses in their XML config, which need to be skipped over when allocating addresses to remaining devices.
