Currently users who want to use virDomainQemuMonitorCommand() API or it's virsh equivalent has to use the same protocol as libvirt uses for communication to qemu. Since the protocol is QMP with current qemu and HMP much more usable for humans, one ends up typing something like the following: virsh qemu-monitor-command DOM \ '{"execute":"human-monitor-command","arguments":{"command-line":"info kvm"}}' which is not a very convenient way of debugging qemu. This patch introduces --hmp option to qemu-monitor-command, which says that the provided command is in HMP. If libvirt uses QMP to talk with qemu, the command will automatically be converted into QMP. So the example above is simplified to just virsh qemu-monitor-command --hmp DOM "info kvm" Also the result is converted from {"return":"kvm support: enabled\r\n"} to just plain HMP: kvm support: enabled If libvirt talks to qemu in HMP, --hmp flag is obviously a noop.

Currently libvirt doesn't confirm whether the guest has responded to the disk removal request. In some cases this can leave the guest with continued access to the device while the mgmt layer believes that it has been removed. With a recent qemu monitor command[1] we can deterministically revoke a guests access to the disk (on the QEMU side) to ensure no futher access is permitted. This patch adds support for the drive_del() command and introduces it in the disk removal paths. If the guest is running in a QEMU without this command we currently explicitly check for unknown command/CommandNotFound and log the issue. If QEMU supports the command we issue the drive_del command after we attempt to remove the device. The guest may respond and remove the block device before we get to attempt to call drive_del. In that case, we explicitly check for 'Device not found' from the monitor indicating that the target drive was auto-deleted upon guest responds to the device removal notification. 1. http://thread.gmane.org/gmane.comp.emulators.qemu/84745Signed-off-by: NRyan Harper <ryanh@us.ibm.com>

This patch adds support for the drive_unplug() command and introduces it in the disk removal paths. There is some discussion to be had about how to handle the case where the guest is running in a QEMU without this command (and the fact that we currently don't have a way of detecting what monitor commands are available). Changes since v2: - use VIR_ERROR to report when unplug command not found Changes since v1: - return > 0 when command isn't present, < 0 on command failure - detect when drive_unplug command isn't present and log error instead of failing entire command Signed-off-by: NRyan Harper <ryanh@us.ibm.com>

I am replacing the last instances of close() I found with VIR_CLOSE() / VIR_FORCE_CLOSE respectively. The first part patches virsh, which I missed out on previously. The 2nd patch I had left out intentionally to look at it more carefully: The 'closed' variable could be easily removed since it wasn't used anywhere else. The possible race condition that could result from the filedescriptor being closed and not set to -1 (and possibly let us write into 'something' totally different if the fd was allocated by another thread) seems to be prevented by the qemuMonitorLock() already placed around the code that reads from or writes to the fd. So the change of this code as shown in the patch should not have any side-effects.

Using automated replacement with sed and editing I have now replaced all occurrences of close() with VIR_(FORCE_)CLOSE() except for one, of course. Some replacements were straight forward, others I needed to pay attention. I hope I payed attention in all the right places... Please have a look. This should have at least solved one more double-close error.

Implement the qemu driver's virDomainQemuMonitorCommand and hook it into the API entry point. Changes since v1: - Rename the (external) qemuMonitorCommand to qemuDomainMonitorCommand - Add virCheckFlags to qemuDomainMonitorCommand Changes since v2: - Drop ATTRIBUTE_UNUSED from the flags Changes since v3: - Add a flag to priv so we only print out monitor command warning once. Note that this has not been plumbed into qemuDomainObjPrivateXMLFormat or qemuDomainObjPrivateXMLParse, which means that if you run a monitor command, restart libvirtd, and then run another monitor command, you may get an an erroneous VIR_INFO. It's a pretty minor matter, and I didn't think it warranted the additional code. - Add BeginJob/EndJob calls around EnterMonitor/ExitMonitor Signed-off-by: NChris Lalancette <clalance@redhat.com>

Some, but not all, codepaths in the qemuMonitorOpen() method would trigger the destroy callback. The caller does not expect this to be invoked if construction fails, only during normal release of the monitor.

The patches for shared storage migration were not correctly written for json mode. Thus the 'blk' and 'inc' parameters were never being set. In addition they didn't set the QEMU_MONITOR_MIGRATE_BACKGROUND so migration was synchronous. Due to multiple bugs in QEMU's JSON impl this wasn't noticed because it treated the sync migration requst as asynchronous anyway. Finally 'background' parameter was converted to take arbitrary flags but not renamed, and not all uses were changed to unsigned int. * src/qemu/qemu_driver.c: Set QEMU_MONITOR_MIGRATE_BACKGROUND in doNativeMigrate * src/qemu/qemu_monitor_json.c: Process QEMU_MONITOR_MIGRATE_NON_SHARED_DISK and QEMU_MONITOR_MIGRATE_NON_SHARED_INC flags * src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h, src/qemu/qemu_monitor_json.h, src/qemu/qemu_monitor_text.c, src/qemu/qemu_monitor_text.h: change 'int background' to 'unsigned int flags' in migration APIs.

The current code pattern requires that callers of qemuMonitorClose check for the return value == 0, and if so, set priv->mon = NULL and release the reference held on the associated virDomainObjPtr The change d84bb6d6 violated that requirement, meaning that priv->mon never gets set to NULL, and a reference count is leaked on virDomainObjPtr. This design was a bad one, so remove the need to check the return valueof qemuMonitorClose(). Instead allow registration of a callback that's invoked just when the last reference on qemuMonitorPtr is released. Finally there was a potential reference leak in qemuConnectMonitor in the failure path. * src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h: Add a destroy callback invoked from qemuMonitorFree * src/qemu/qemu_driver.c: Use the destroy callback to release the reference on virDomainObjPtr when the monitor is freed.

When closing a monitor using qemuMonitorClose(), we are aware of the possibility the monitor is still being used somewhere: /* NB: ordinarily one might immediately set mon->watch to -1 * and mon->fd to -1, but there may be a callback active * that is still relying on these fields being valid. So * we merely close them, but not clear their values and * use this explicit 'closed' flag to track this state */ but since we call virEventAddHandle() on that monitor without increasing its ref counter, the monitor is still freed which makes possible users of it quite unhappy. The unhappiness can lead to a hang if qemuMonitorIO tries to lock mutex which no longer exists.

Support for live migration between hosts that do not share storage was added to qemu-kvm release 0.12.1. It supports two flags: -b migration without shared storage with full disk copy -i migration without shared storage with incremental copy (same base image shared between source and destination). I tested the live migration without shared storage (both flags) for native and p2p with and without tunnelling. I also verified that the fix doesn't affect normal migration with shared storage.

The save process was relying on use of the shell >> append operator to ensure the save data was placed after the libvirt header + XML. This doesn't work for block devices though. Replace this code with use of 'dd' and its 'seek' parameter. This means that we need to pad the header + XML out to a multiple of dd block size (in this case we choose 512). The qemuMonitorMigateToCommand() monitor API is used for both save/coredump, and migration via UNIX socket. We can't simply switch this to use 'dd' since this causes problems with the migration usage.

Thus to support this, we iteratively toggle the online state when the total number of vCPUs is adjusted via libvirt NB, currently untested since QEMU segvs when running this! * src/qemu/qemu_driver.c: Toggle online state for CPUs when doing hotplug * 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 monitor API for toggling a CPU's online status via 'set_cpu

When in JSON mode, QEMU requires that 'qmp_capabilities' is run as the first command in the monitor. This is a no-op when run in the text mode monitor * src/qemu/qemu_driver.c: Run capabilities negotiation when connecting to the monitor * src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h, src/qemu/qemu_monitor_json.c, src/qemu/qemu_monitor_json.h: Add support for the 'qmp_capabilities' command, no-op in text mode.
