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.

The qemuMigrationToFile method was accidentally annotated for the 'compressor' parameter to be non-null, instead of the 'path' parameter. Thus GCC with -O2, unhelpfully deleted the entire 'if (compressor == NULL)' block of code during optimization. Thus NULL was passed to virCommandNew() with predictably bad results. * src/qemu/qemu_migration.h: Fix non-null annotation to be against path instead of compressor

Clang warned about a dead assignment. In the process, I noticed that we are only using the function for a bool value. I audited all other callers in qemu_{migration,cgroup,driver,hotplug), and all were making the call in a bool context. Also, do bounds checking on the argument. * src/qemu/qemu_cgroup.c (qemuSetupCgroup): Delete dead assignment. (qemuCgroupControllerActive): Change return type to bool. * src/qemu/qemu_cgroup.h (qemuCgroupControllerActive): Likewise.

This code has had problems historically. As originally written, in commit 6bcf2501 (Jun 08), it could call unlink on a random string, nuking an unrelated file. Then commit 182a80b9 (Sep 09), the code was rewritten to allocate tmp, with both a use-after-free bug and a chance to call unlink(NULL). Commit e206946d (Mar 11) fixed the use-after-free, but not the NULL dereference. Thanks to clang for catching this! * src/qemu/qemu_driver.c (qemudDomainMemoryPeek): Don't call unlink on NULL.

Without initializing it, we could return some an undefined value from this function. While I was at it, I made a trivial whitespace change in the same function to improve readability.

This patch adds functions for modify domain's persistent definition. To do error recovery in easy way, we use a copy of vmdef and update it. The whole sequence will be: make a copy of domain definition. if (flags & MODIFY_CONFIG) update copied domain definition if (flags & MODIF_LIVE) do hotplug. if (no error) save copied one to the file and update cached definition. else discard copied definition.

The two ends of the pipe used for feeding QEMU tunnelled migration data were interchanged, so QEMU got given the "write" end instead of the "read" end.

This patch does the following two things: 1. hold an extra reference while handling watchdog event If the domain is not persistent, and qemu quits unexpectedly before calling processWatchdogEvent(), vm will be freed and the function processWatchdogEvent() will be dangerous. 2. unlock qemu driver and vm before returning from processWatchdogEvent() When the function processWatchdogEvent() failed, we only free wdEvent, but forget to unlock qemu driver and vm, free dumpfile.

We do not lock qemu_driver when calling virThreadPoolNew(). If it failed, we will unlock qemu_driver. It is dangerous. We may use this pool during auto starting domains. So we must create it before calling qemuAutostartDomains(). Otherwise, libvirtd will crash.
