The new introduced optional attribute "copy_on_read</code> controls whether to copy read backing file into the image file. The value can be either "on" or "off". Copy-on-read avoids accessing the same backing file sectors repeatedly and is useful when the backing file is over a slow network. By default copy-on-read is off.

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.

Implement the parsing and formatting of the XML addition of the previous commit. The new XML doesn't affect qemu command line, so we can now test round-trip XML->memory->XML handling.

The RNG for <seclabel> was too strict - if it was present, then it had to have sub-elements, even if those didn't make sense for the given attributes. Also, we didn't have any tests of <seclabel> parsing or XML output. In this patch, I added more parsing tests than output tests (since the output populates and/or reorders fields not present in certain inputs). Making the RNG reliable is a precursor to using <seclabel> variants in more places in the XML in later patches.

Currently non-x86 guests must have <acpi/> defined in <features> to prevent libvirt from running qemu with -no-acpi. Although it works, it is a hack. Instead add a capability flag which indicates whether qemu understands the -no-acpi option. Use it to control whether libvirt emits -no-acpi. Current versions of qemu always display -no-acpi in their help output, so this patch has no effect. However the development version of qemu has been modified such that -no-acpi is only displayed when it is actually supported. Signed-off-by: NMichael Ellerman <michael@ellerman.id.au>

This improves the support for qemu rbd devices by adding support for a few key features (e.g., authentication) and cleaning up the way in which rbd configuration options are passed to qemu. An <auth> member of the disk source xml specifies how librbd should authenticate. The username attribute is the Ceph/RBD user to authenticate as. The usage or uuid attributes specify which secret to use. Usage is an arbitrary identifier local to libvirt. The old RBD support relied on setting an environment variable to communicate information to qemu/librbd. Instead, pass those options explicitly to qemu. Update the qemu argument parsing and tests accordingly. Signed-off-by: NSage Weil <sage@newdream.net> Signed-off-by: NJosh Durgin <josh.durgin@dreamhost.com>

Previously libvirt's disk device XML only had a single attribute, error_policy, to control both read and write error policy, but qemu has separate options for controlling read and write. In one case (enospc) a policy is allowed for write errors but not read errors. This patch adds a separate attribute that sets only the read error policy. If just error_policy is set, it will apply to both read and write error policy (previous behavior), but if the new rerror_policy attribute is set, it will override error_policy for read errors only. Possible values for rerror_policy are "stop", "report", and "ignore" ("report" is the qemu-controlled default for rerror_policy when error_policy isn't specified). For consistency, the value "report" has been added to the possible values for error_policy as well.

commit 12062abb set rerror=ignore when error_policy="enospace" was selected (since the rerror option in qemu doesn't accept "enospc", as the werror option does). After that patch was already pushed, Paolo Bonzini noticed it and commented that leaving rerror at the default ("report") would be a better choice. This patch corrects the problem - if error_policy = "enospace" is given, rerror is left off the qemu commandline, effectively setting it to "report". For other values, rerror is still set to match werror. Additionally, the parsing of error_policy was changed to no longer erroneously allow "default" as a choice - as with most other attributes, if you want the default setting, just don't specify an error_policy. Finally, two ommissions in the first patch were corrected - a long-dormant qemuxml2argv test for enospace was enabled, and fixed to pass, and the argv2xml parser in qemu_command.c was updated to recognize the different spelling on the qemu commandline.

The commit that prevents disk corruption on domain shutdown (96fc4784) 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 uses USB bus name "usb.0" when using the legacy -usb argument. If we want to allow USB devices to specify their addresses with legacy -usb, we should either in case of legacy bus name drop the 0 from the address bus, or just drop the 0 from device id. This patch does the later. Another solution would be to permit addressing on non-legacy USB controllers only.

In some versions of qemu, both virtio-blk-pci and virtio-net-pci devices can have an event_idx setting that determines some details of event processing. When it is enabled, it "reduces the number of interrupts and exits for the guest". qemu will automatically enable this feature when it is available, but there may be cases where this new feature could actually make performance worse (NB: no such case has been found so far). As a safety switch in case such a situation is encountered in the field, this patch adds a new attribute "event_idx" to the <driver> element of both disk and interface devices. event_idx can be set to "on" (to force event_idx on in case qemu has it disabled by default) or "off" (for force event_idx off). In the case that event_idx support isn't present in qemu, the attribute is ignored (this on the advice of the qemu developer). docs/formatdomain.html.in: document the new flag (marking it as "don't mess with this!" docs/schemas/domain.rng: add event_idx in appropriate places src/conf/domain_conf.[ch]: add event_idx to parser and formatter src/libvirt_private.syms: export virDomainVirtioEventIdx(From|To)String src/qemu/qemu_capabilities.[ch]: detect and report event_idx in disk/net src/qemu/qemu_command.c: add event_idx parameter to qemu commandline when appropriate. tests/qemuxml2argvdata/qemuxml2argv-event_idx.args, tests/qemuxml2argvdata/qemuxml2argv-event_idx.xml, tests/qemuxml2argvtest.c, tests/qemuxml2xmltest.c: test cases for event_idx.

For controlled shutdown we issue a 'system_powerdown' command to the QEMU monitor. This triggers an ACPI event which (most) guest OS wire up to a controlled shutdown. There is no equiv ACPI event to trigger a controlled reboot. This patch attempts to fake a reboot. - In qemuDomainObjPrivatePtr we have a bool fakeReboot flag. - The virDomainReboot method sets this flag and then triggers a normal 'system_powerdown'. - The QEMU process is started with '-no-shutdown' so that the guest CPUs pause when it powers off the guest - When we receive the 'POWEROFF' event from QEMU JSON monitor if fakeReboot is not set we invoke the qemuProcessKill command and shutdown continues normally - If fakeReboot was set, we spawn a background thread which issues 'system_reset' to perform a warm reboot of the guest hardware. Then it issues 'cont' to start the CPUs again * src/qemu/qemu_command.c: Add -no-shutdown flag if we have JSON support * src/qemu/qemu_domain.h: Add 'fakeReboot' flag to qemuDomainObjPrivate struct * src/qemu/qemu_driver.c: Fake reboot using the system_powerdown command if JSON support is available * src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h, src/qemu/qemu_monitor_json.c, src/qemu/qemu_monitor_json.h, src/qemu/qemu_monitor_text.c, src/qemu/qemu_monitor_text.h: Add binding for system_reset command * src/qemu/qemu_process.c: Reset the guest & start CPUs if fakeReboot is set

For virtio disks and interfaces, qemu allows users to enable or disable ioeventfd feature. This means, qemu can execute domain code, while another thread waits for I/O event. Basically, in some cases it is win, in some loss. This feature is available via 'ioeventfd' attribute in disk and interface <driver> element. It accepts 'on' and 'off'. Leaving this attribute out defaults to hypervisor decision.
