Update the qemuDomainMigrateBegin method so that it accepts an optional incoming XML document. This will be validated for ABI compatibility against the current domain config, and if this check passes, will be passed back out for use by the qemuDomainMigratePrepare method on the target * src/qemu/qemu_domain.c, src/qemu/qemu_domain.h, src/qemu/qemu_migration.c: Allow custom XML to be passed

Originally most of libvirt domain-specific calls were blocking during a migration. A new mechanism to allow specific calls (blkstat/blkinfo) to be executed in such condition has been implemented. In the long term it'd be desirable to get a more general solution to mark further APIs as migration safe, without needing special case code. * src/qemu/qemu_migration.c: add some additional job signal flags for doing blkstat/blkinfo during a migration * src/qemu/qemu_domain.c: add a condition variable that can be used to efficiently wait for the migration code to clear the signal flag * src/qemu/qemu_driver.c: execute blkstat/blkinfo using the job signal flags during migration

These VIR_XXXX0 APIs make us confused, use the non-0-suffix APIs instead. How do these coversions works? The magic is using the gcc extension of ##. When __VA_ARGS__ is empty, "##" will swallow the "," in "fmt," to avoid compile error. example: origin after CPP high_level_api("%d", a_int) low_level_api("%d", a_int) high_level_api("a string") low_level_api("a string") About 400 conversions. 8 special conversions: VIR_XXXX0("") -> VIR_XXXX("msg") (avoid empty format) 2 conversions VIR_XXXX0(string_literal_with_%) -> VIR_XXXX(%->%%) 0 conversions VIR_XXXX0(non_string_literal) -> VIR_XXXX("%s", non_string_literal) (for security) 6 conversions Signed-off-by: NLai Jiangshan <laijs@cn.fujitsu.com>

As well as taint warnings going to the main libvirt log, add taint warnings to the per-domain logfile Domain id=3 is tainted: high-privileges Domain id=3 is tainted: disk-probing Domain id=3 is tainted: shell-scripts Domain id=3 is tainted: custom-monitor * src/qemu/qemu_domain.c, src/qemu/qemu_domain.h: Enhance qemuDomainTaint to also log to the domain logfile * src/qemu/qemu_driver.c: Pass -1 for logFD to taint methods to auto-append to logfile * src/qemu/qemu_process.c: Pass open logFD at startup for taint methods

We already have virAsprintf, so picking a similar name helps for seeing a similar purpose. Furthermore, the prefix V before printf generally implies 'va_list', even though this variant was '...', and the old name got in the way of adding a new va_list version. global rename performed with: $ git grep -l virBufferVSprintf \ | xargs -L1 sed -i 's/virBufferVSprintf/virBufferAsprintf/g' then revert the changes in ChangeLog-old.

To cope with the QEMU binary being changed while a VM is running, it is neccessary to persist the original qemu capabilities at the time the VM is booted. * src/qemu/qemu_capabilities.c, src/qemu/qemu_capabilities.h: Add an enum for a string rep of every capability * src/qemu/qemu_domain.c, src/qemu/qemu_domain.h: Support for storing capabilities in the domain status XML * src/qemu/qemu_process.c: Populate & free QEMU capabilities at domain startup

In qemuDomainObjBeginJobWithDriver, when virCondWaitUntil timeouts, the function tries to call qemuDriverLock with virDomainObj locked, this causes the dead-lock problem. This patch fixes this.

Steps to reproduce this bug: # cat test.sh #! /bin/bash -x virsh start domain sleep 5 virsh qemu-monitor-command domain 'cpu_set 2 online' --hmp # while true; do ./test.sh ; done Then libvirtd will crash. The reason is that: we add a reference of obj when we open the monitor. We will reduce this reference when we free the monitor. If the reference of monitor is 0, we will free monitor automatically and the reference of obj is reduced. But in the function qemuDomainObjExitMonitorWithDriver(), we reduce this reference again when the reference of monitor is 0. It will cause the obj be freed in the function qemuDomainObjEndJob(). Then we start the domain again, and libvirtd will crash in the function virDomainObjListSearchName(), because we pass a null pointer(obj->def->name) to strcmp().

The introduction of the v3 migration protocol, along with support for migration cookies, will significantly expand the size of the migration code. Move it all to a separate file to make it more manageable The functions are not moved 100%. The API entry points remain in the main QEMU driver, but once the public virDomainPtr is resolved to the internal virDomainObjPtr, all following code is moved. This will allow the new v3 API entry points to call into the same shared internal migration functions * src/qemu/qemu_domain.c, src/qemu/qemu_domain.h: Add qemuDomainFormatXML helper method * src/qemu/qemu_driver.c: Remove all migration code * src/qemu/qemu_migration.c, src/qemu/qemu_migration.h: Add all migration code.
