qemu: require qmp on new enough qemu The qemu developers have made it clear that modern qemu will no longer guarantee human monitor command stability; furthermore, some features, such as async events, are only supported via qmp. If we are compiled without support for handling JSON, we cannot expect to sanely interact with modern qemu. However, things must continue to build on RHEL 5, where qemu is stuck at 0.10, and where yajl is not available. Another benefit of this patch: future additions of new monitor commands need only focus on qemu_monitor_json.c, instead of also wasting time with qemu_monitor_text.c. * src/qemu/qemu_capabilities.c (qemuCapsComputeCmdFlags): Report error if yajl is missing but qemu requires qmp.

The affected versions of QEMU do not quit on SIGTERM if started with -no-shutdown, which we use to implement fake reboot. Since -no-shutdown tells QEMU not to quit automatically on guest shutdown, domains started using the affected QEMU cannot be shutdown properly and stay in a paused state. This patch disables fake reboot feature on such QEMU by not using -no-shutdown, which makes shutdown work as expected. However, virDomainReboot will not work in this case and it will report "Requested operation is not valid: Reboot is not supported with this QEMU binary".

qemu: Fix shutdown regression with buggy qemu The commit that prevents disk corruption on domain shutdown (96fc4784177ecb70357518fa863442455e45ad0e) causes regression with QEMU 0.14.* and 0.15.* because of a regression bug in QEMU that was fixed only recently in QEMU git. The affected versions of QEMU do not quit on SIGTERM if started with -no-shutdown, which we use to implement fake reboot. Since -no-shutdown tells QEMU not to quit automatically on guest shutdown, domains started using the affected QEMU cannot be shutdown properly and stay in a paused state. This patch disables fake reboot feature on such QEMU by not using -no-shutdown, which makes shutdown work as expected. However, virDomainReboot will not work in this case and it will report "Requested operation is not valid: Reboot is not supported with this QEMU binary".

QEMU_CAPS_DRIVE_AIO,
qemu: add ability to set PCI device "rombar" on or off This patch was made in response to: https://bugzilla.redhat.com/show_bug.cgi?id=738095 In short, qemu's default for the rombar setting (which makes the firmware ROM of a PCI device visible/not on the guest) was previously 0 (not visible), but they recently changed the default to 1 (visible). Unfortunately, there are some PCI devices that fail in the guest when rombar is 1, so the setting must be exposed in libvirt to prevent a regression in behavior (it will still require explicitly setting <rom bar='off'/> in the guest XML). rombar is forced on/off by adding: <rom bar='on|off'/> inside a <hostdev> element that defines a PCI device. It is currently ignored for all other types of devices. At the moment there is no clean method to determine whether or not the rombar option is supported by QEMU - this patch uses the advice of a QEMU developer to assume support for qemu-0.12+. There is currently a patch in the works to put this information in the output of "qemu-kvm -device pci-assign,?", but of course if we switch to keying off that, we would lose support for setting rombar on all the versions of qemu between 0.12 and whatever version gets that patch.

QEMU_CAPS_PCI_ROMBAR,
qemu: add new disk device='lun' for bus='virtio' & type='block' In the past, generic SCSI commands issued from a guest to a virtio disk were always passed through to the underlying disk by qemu, and the kernel would also pass them on. As a result of CVE-2011-4127 (see: http://seclists.org/oss-sec/2011/q4/536), qemu now honors its scsi=on|off device option for virtio-blk-pci (which enables/disables passthrough of generic SCSI commands), and the kernel will only allow the commands for physical devices (not for partitions or logical volumes). The default behavior of qemu is still to allow sending generic SCSI commands to physical disks that are presented to a guest as virtio-blk-pci devices, but libvirt prefers to disable those commands in the standard virtio block devices, enabling it only when specifically requested (hopefully indicating that the requester understands what they're asking for). For this purpose, a new libvirt disk device type (device='lun') has been created. device='lun' is identical to the default device='disk', except that: 1) It is only allowed if bus='virtio', type='block', and the qemu version is "new enough" to support it ("new enough" == qemu 0.11 or better), otherwise the domain will fail to start and a CONFIG_UNSUPPORTED error will be logged). 2) The option "scsi=on" will be added to the -device arg to allow SG_IO commands (if device !='lun', "scsi=off" will be added to the -device arg so that SG_IO commands are specifically forbidden). Guests which continue to use disk device='disk' (the default) will no longer be able to use SG_IO commands on the disk; those that have their disk device changed to device='lun' will still be able to use SG_IO commands. *docs/formatdomain.html.in - document the new device attribute value. *docs/schemas/domaincommon.rng - allow it in the RNG *tests/* - update the args of several existing tests to add scsi=off, and add one new test that will test scsi=on. *src/conf/domain_conf.c - update domain XML parser and formatter *src/qemu/qemu_(command|driver|hotplug).c - treat VIR_DOMAIN_DISK_DEVICE_LUN *almost* identically to VIR_DOMAIN_DISK_DEVICE_DISK, except as indicated above. Note that no support for this new device value was added to any hypervisor drivers other than qemu, because it's unclear what it might mean (if anything) to those drivers.

Unfortunately, there are some PCI devices that fail in the guest when rombar is 1, so the setting must be exposed in libvirt to prevent a regression in behavior (it will still require explicitly setting <rom bar='off'/> in the guest XML). rombar is forced on/off by adding: <rom bar='on|off'/> inside a <hostdev> element that defines a PCI device. It is currently ignored for all other types of devices. At the moment there is no clean method to determine whether or not the rombar option is supported by QEMU - this patch uses the advice of a QEMU developer to assume support for qemu-0.12+. There is currently a patch in the works to put this information in the output of "qemu-kvm -device pci-assign,?", but of course if we switch to keying off that, we would lose support for setting rombar on all the versions of qemu between 0.12 and whatever version gets that patch.

qemu: add new disk device='lun' for bus='virtio' & type='block' In the past, generic SCSI commands issued from a guest to a virtio disk were always passed through to the underlying disk by qemu, and the kernel would also pass them on. As a result of CVE-2011-4127 (see: http://seclists.org/oss-sec/2011/q4/536), qemu now honors its scsi=on|off device option for virtio-blk-pci (which enables/disables passthrough of generic SCSI commands), and the kernel will only allow the commands for physical devices (not for partitions or logical volumes). The default behavior of qemu is still to allow sending generic SCSI commands to physical disks that are presented to a guest as virtio-blk-pci devices, but libvirt prefers to disable those commands in the standard virtio block devices, enabling it only when specifically requested (hopefully indicating that the requester understands what they're asking for). For this purpose, a new libvirt disk device type (device='lun') has been created. device='lun' is identical to the default device='disk', except that: 1) It is only allowed if bus='virtio', type='block', and the qemu version is "new enough" to support it ("new enough" == qemu 0.11 or better), otherwise the domain will fail to start and a CONFIG_UNSUPPORTED error will be logged). 2) The option "scsi=on" will be added to the -device arg to allow SG_IO commands (if device !='lun', "scsi=off" will be added to the -device arg so that SG_IO commands are specifically forbidden). Guests which continue to use disk device='disk' (the default) will no longer be able to use SG_IO commands on the disk; those that have their disk device changed to device='lun' will still be able to use SG_IO commands. *docs/formatdomain.html.in - document the new device attribute value. *docs/schemas/domaincommon.rng - allow it in the RNG *tests/* - update the args of several existing tests to add scsi=off, and add one new test that will test scsi=on. *src/conf/domain_conf.c - update domain XML parser and formatter *src/qemu/qemu_(command|driver|hotplug).c - treat VIR_DOMAIN_DISK_DEVICE_LUN *almost* identically to VIR_DOMAIN_DISK_DEVICE_DISK, except as indicated above. Note that no support for this new device value was added to any hypervisor drivers other than qemu, because it's unclear what it might mean (if anything) to those drivers.

qemu: Fix shutdown regression with buggy qemu The commit that prevents disk corruption on domain shutdown (96fc4784177ecb70357518fa863442455e45ad0e) causes regression with QEMU 0.14.* and 0.15.* because of a regression bug in QEMU that was fixed only recently in QEMU git. The affected versions of QEMU do not quit on SIGTERM if started with -no-shutdown, which we use to implement fake reboot. Since -no-shutdown tells QEMU not to quit automatically on guest shutdown, domains started using the affected QEMU cannot be shutdown properly and stay in a paused state. This patch disables fake reboot feature on such QEMU by not using -no-shutdown, which makes shutdown work as expected. However, virDomainReboot will not work in this case and it will report "Requested operation is not valid: Reboot is not supported with this QEMU binary".

"-global" is the only way to define vram_size for the primary qxl device, regardless of how qemu names it, (It's not good a good way, as original idea of "-global" is to set a global default for a driver property, but to specify vram for first qxl device, we have to use it). For other qxl devices, as they are represented by "-device", could specify it directly and seperately for each, and it overrides the default set by "-global" if specified. v1 - v2: * modify "virDomainVideoDefaultRAM" so that it returns 16M as the default vram_size for qxl device. * vram_size * 1024 (qemu accepts bytes for vram_size). * apply default vram_size for qxl device for which vram_size is not specified. * modify "graphics-spice" tests (more sensiable vram_size) * Add an argument of virDomainDefPtr type for qemuBuildVideoDevStr, to use virDomainVideoDefaultRAM in qemuBuildVideoDevStr). v2 - v3: * Modify default video memory size for qxl device from 16M to 24M * Update codes to be consistent with changes on qemu_capabilities.*

The default behavior of qemu is still to allow sending generic SCSI commands to physical disks that are presented to a guest as virtio-blk-pci devices, but libvirt prefers to disable those commands in the standard virtio block devices, enabling it only when specifically requested (hopefully indicating that the requester understands what they're asking for). For this purpose, a new libvirt disk device type (device='lun') has been created. device='lun' is identical to the default device='disk', except that: 1) It is only allowed if bus='virtio', type='block', and the qemu version is "new enough" to support it ("new enough" == qemu 0.11 or better), otherwise the domain will fail to start and a CONFIG_UNSUPPORTED error will be logged). 2) The option "scsi=on" will be added to the -device arg to allow SG_IO commands (if device !='lun', "scsi=off" will be added to the -device arg so that SG_IO commands are specifically forbidden). Guests which continue to use disk device='disk' (the default) will no longer be able to use SG_IO commands on the disk; those that have their disk device changed to device='lun' will still be able to use SG_IO commands. *docs/formatdomain.html.in - document the new device attribute value. *docs/schemas/domaincommon.rng - allow it in the RNG *tests/* - update the args of several existing tests to add scsi=off, and add one new test that will test scsi=on. *src/conf/domain_conf.c - update domain XML parser and formatter *src/qemu/qemu_(command|driver|hotplug).c - treat VIR_DOMAIN_DISK_DEVICE_LUN *almost* identically to VIR_DOMAIN_DISK_DEVICE_DISK, except as indicated above. Note that no support for this new device value was added to any hypervisor drivers other than qemu, because it's unclear what it might mean (if anything) to those drivers.

qemu: Support for Block Device IO Limits. Implementation of iolimits for the qemu driver with capability probing for block size attribute and command line generation for block sizes. Including testcase for qemuxml2argvtest. Signed-off-by: Viktor Mihajlovski <mihajlov@linux.vnet.ibm.com>

QEMU_CAPS_VIRTIO_SCSI_PCI,
Rename iolimit to blockio. After discussion with DB we decided to rename the new iolimit element as it creates the impression it would be there to limit (i.e. throttle) I/O instead of specifying immutable characteristics of a block device. This is also backed by the fact that the term I/O Limits has vanished from newer storage admin documentation. Signed-off-by: Viktor Mihajlovski <mihajlov@linux.vnet.ibm.com>
