[libvirt] [PATCH v4 0/6] vz: add migration support
by Nikolay Shirokovskiy 04 Sep '15

04 Sep '15

NOTE that minimal command to migrate vz domain is like next: virsh -c vz:///system migrate 200 vz+ssh://shiny0/system --p2p --live --compressed --persistent --undefinesource ==Difference from v1: 1. Patch is quite different. First patchset implements migration thru managed migration scheme. This one goes thru p2p scheme. I belive this is a better approach. Vz migration is done via vz sdk and first patchset uses 5 phased migration only to get a token from destination on prepare phase which is kind a misuse. This patch just adds vz specific function to driver interface to archive the same goal. 2. Offline migration is supported as there is no more dependency on current flow of managed migration scheme. ==Difference from v2: 1. Implement thru direct migration instead of p2p. p2p is just managed 5-staged migration when managing is done on daemon side. Vz migration stages are all hidden in vz sdk and thus it would be more consistent to use direct scheme. 2. Use existing driver function for prepare migration phase to pass session uuid from destination to source instead of new one. As vz migration is direct one we will not use prepare phase function in a straight forward manner anyway. ==Difference from v3: Return back to p2p implementation. Difference from p2p implementation in v2 is that prepare phase driver function is used to pass session_uuid from destination to source instead of new ad-hoc driver function. src/vz/vz_driver.c | 342 ++++++++++++++++++++++++++++++++++++++++++++++++++++ src/vz/vz_sdk.c | 86 +++++++++++-- src/vz/vz_sdk.h | 6 + src/vz/vz_utils.h | 4 +- 4 files changed, 423 insertions(+), 15 deletions(-)

[libvirt] [RFC PATCH 0/3] Implement mockup capabilities cache in QEMU tests
by Pavel Fedin 04 Sep '15

04 Sep '15

Since commit e8d55172544c1fafe31a9e09346bdebca4f0d6f9 qemu driver checks emulator capabilities during domain XML post-parse. However, test suite does not initialize it, therefore a condition to skip all checks if there is no cache supplied was added. This is actually a hack, whose sole purpose is to make existing test suite working. Additionally, it prevents from writing new tests for this particular functionality. This series attempts to solve this problem by implementing proper cache mockup in test suite. The main idea is to create a cache in standard way and put there a pre-defined capabilities set (which tests already have). The main problem here is to know emulator binary name, which is contained in the source XML. However, we have to create our cache before reading the XML. The simplest way to resolve this is to assume particular binary name from test name. Currently tests which assume cross-architecture binary are all prefixed with the architecture name (with one exception of "keywrap" tests which all assume /usr/bin/qemu-system-s390x and do not have "s390-" prefix in their name). This scheme works fine, unless we use "native" emulator binary. Here we have a mess. Most newer tests use /usr/bin/qemu, however there is a large number of tests which use /usr/libexec/qemu-kvm or /usr/bin/kvm (i guess these are leftovers from the epoch when qemu-kvm was a separate fork of qemu). This is currently not handled in any way, and these tests may report errors due to missing binaries (because virQEMUCapsCacheLookup() attempts to populate the cache automatically by querying the binary if not already known). There are several possible ways to resolve this: a) Add all possible names as aliases for /usr/bin/qemu b) Forbid to use oldstyle names at all in these tests c) Declare some prefix like "kvm-" for those tests who want to use /usr/libexec/qemu-kvm. Again, this would ban /usr/bin/kvm and /usr/bin/qemu-kvm (if not using aliases like in (b) d) Hardcode (optional) emulator name per test. IMHO a bad idea because number of tests is huge. e) Do some preparsing of the XML and extract binary name from it. Again, i disliked it for not being simple enough. I also thought about an alternate implementation which would patch postParseCallback and insert own function there which builds a cache. At this point binary name is already known from the XML. However, such a design looks like an ugly hack by itself, so i stopped going in this direction. Comments and opinions are welcome.

[libvirt] [PATCH] libxl: report correct errno from virNetSocketNewConnectTCP on migration

saved_errno is never written to in this function after it is initialised and it is only used to log the failure from virNetSocketNewConnectTCP masking the real errno from that function.

[libvirt] [PATCH] remoteClientCloseFunc: Don't mangle connection object refcount

Well, in 8ad126e6 we tried to fix a memory corruption problem. However, the fix was not as good as it could be. I mean, the commit has one line more than it should. I've noticed this output just recently: # ./run valgrind --leak-check=full --show-reachable=yes ./tools/virsh domblklist gentoo ==17019== Memcheck, a memory error detector ==17019== Copyright (C) 2002-2013, and GNU GPL'd, by Julian Seward et al. ==17019== Using Valgrind-3.10.1 and LibVEX; rerun with -h for copyright info ==17019== Command: /home/zippy/work/libvirt/libvirt.git/tools/.libs/virsh domblklist gentoo ==17019== Target Source ------------------------------------------------ fda /var/lib/libvirt/images/fd.img vda /var/lib/libvirt/images/gentoo.qcow2 hdc /home/zippy/tmp/install-amd64-minimal-20150402.iso ==17019== Thread 2: ==17019== Invalid read of size 4 ==17019== at 0x4EFF5B4: virObjectUnref (virobject.c:258) ==17019== by 0x5038CFF: remoteClientCloseFunc (remote_driver.c:552) ==17019== by 0x5069D57: virNetClientCloseLocked (virnetclient.c:685) ==17019== by 0x506C848: virNetClientIncomingEvent (virnetclient.c:1852) ==17019== by 0x5082136: virNetSocketEventHandle (virnetsocket.c:1913) ==17019== by 0x4ECD64E: virEventPollDispatchHandles (vireventpoll.c:509) ==17019== by 0x4ECDE02: virEventPollRunOnce (vireventpoll.c:658) ==17019== by 0x4ECBF00: virEventRunDefaultImpl (virevent.c:308) ==17019== by 0x130386: vshEventLoop (vsh.c:1864) ==17019== by 0x4F1EB07: virThreadHelper (virthread.c:206) ==17019== by 0xA8462D3: start_thread (in /lib64/libpthread-2.20.so) ==17019== by 0xAB441FC: clone (in /lib64/libc-2.20.so) ==17019== Address 0x139023f4 is 4 bytes inside a block of size 240 free'd ==17019== at 0x4C2B1F0: free (in /usr/lib64/valgrind/vgpreload_memcheck-amd64-linux.so) ==17019== by 0x4EA8949: virFree (viralloc.c:582) ==17019== by 0x4EFF6D0: virObjectUnref (virobject.c:273) ==17019== by 0x4FE74D6: virConnectClose (libvirt.c:1390) ==17019== by 0x13342A: virshDeinit (virsh.c:406) ==17019== by 0x134A37: main (virsh.c:950) The problem is, when registering remoteClientCloseFunc(), it's conn->closeCallback which is ref'd. But in the function itself it's conn->closeCallback->conn what is unref'd. This is causing imbalance in reference counting. Moreover, there's no need for the remote driver to increase/decrease conn refcount since it's not used anywhere. It's just merely passed to client registered callback. And for that purpose it's correctly ref'd in virConnectRegisterCloseCallback() and then unref'd in virConnectUnregisterCloseCallback().
