[libvirt] virNetClientPtr leak in remote driver
by Matthias Bolte 04 Aug '11

04 Aug '11

doRemoteClose doesn't free the virNetClientPtr and this creates a 260kb leak per remote connection. This happens because virNetClientFree doesn't remove the last ref, because virNetClientNew creates the virNetClientPtr with a refcount of 2. static virNetClientPtr virNetClientNew(virNetSocketPtr sock, const char *hostname) { [...] client->refs = 1; [...] /* Set up a callback to listen on the socket data */ client->refs++; if (virNetSocketAddIOCallback(client->sock, VIR_EVENT_HANDLE_READABLE, virNetClientIncomingEvent, client, virNetClientEventFree) < 0) { client->refs--; VIR_DEBUG("Failed to add event watch, disabling events"); } [...] } virNetClientNew adds a ref before calling virNetSocketAddIOCallback but only removes it when virNetSocketAddIOCallback fails. This seems wrong too me and the ref should be removed in the success case too. The same pattern was added in 0302391ee643ad91fdc6d2ecf7e4cf0fc9724516 (Fix race in ref counting when handling RPC jobs) --- a/src/rpc/virnetserverclient.c +++ b/src/rpc/virnetserverclient.c @@ -763,10 +763,12 @@ readmore: /* Send off to for normal dispatch to workers */ if (msg) { + client->refs++; if (!client->dispatchFunc || client->dispatchFunc(client, msg, client->dispatchOpaque) < 0) { virNetMessageFree(msg); client->wantClose = true; + client->refs--; return; } } Again, this seems wrong and the ref should be removed in the success case here too. Before I spent time to figure out how the refcounting is supposed to work here I just report it and hope that Dan can easily fix this. -- Matthias Bolte http://photron.blogspot.com

[libvirt] REG: JAVA API for physical host addition
by srivatsan jagannathan 04 Aug '11

04 Aug '11

Hi Team, I working on performance measurement of various cloud management software. I am working on code such that it will calculate (cpu usage, memory usage, disk io, time of operation & network bandwidth usage) for various cloud management operation. once such operation is adding 2 or 3 physical host and obtain the above measurement. Is there is any java api that support this function. what I need is for creating instance there is method Create() in class Domain, I need same operation for physical host. Regards, Srivatsan J.

[libvirt] speeding up qemu core dumps
by Jim Fehlig 04 Aug '11

04 Aug '11

Hi All, I've had user reports of "libvirt limiting KVM core dumps". This isn't quite true since libvirt just uses the default migration speed defined in qemu's migration.c /* Migration speed throttling */ static int64_t max_throttle = (32 << 20); AFAIK, there's not much interest in changing the qemu default http://lists.nongnu.org/archive/html/qemu-devel/2011-02/msg01156.html I thought there were more discussions on the topic but can only find the above thread ATM. Do folks here have objections to increasing the migration speed prior to core dump? If not, any suggestions for a value? I set the migration speed to 1G in doCoreDump() prior to calling qemuMigrationToFile() with following improvement dumping a 4G guest 32MiB/s migration speed (qemu default): # time virsh dump --live test /tmp/dump Domain test dumped to /tmp/dump real 0m10.121s user 0m0.004s sys 0m0.004s 1GiB/s migration speed: # time virsh dump --live test /tmp/dump Domain test dumped to /tmp/dump real 0m3.745s user 0m0.004s sys 0m0.004s I suppose the same applies for save. Regards, Jim

[libvirt] [PATCH] build: update to latest gnulib
by Eric Blake 03 Aug '11

03 Aug '11

I noticed that with 0.9.4, gnulib ended up replacing pthread_sigmask on glibc, even though glibc's works perfectly fine. It turns out to have been an upstream gnulib bug. * .gnulib: Update to latest, for pthread_sigmask fix. --- This missed the 0.9.4 release; oh well. * .gnulib 41a7841...7f494c7 (18): > pthread_sigmask: Actually use results of gl_THREADLIB. > autoupdate > maint.mk: relax the default _gl_TS_function_match regexp > git-version-gen: document that EXTRA_DIST must include .version > wctype-h: Fix last change. > frexpl: Update autoconf test. > sys_utsname: Add support for Minix. > strings: Add support for Minix. > wctype-h: Add support for Minix. > * lib/xalloc.h (DEFAULT_MXFAST): Track 64-bit glibc. > stdioext: Add support for Minix. > errno: Port to Minix. > Work around declaration collisions on Minix. > Add support for Minix with ACK compiler. > Documentation about Minix. > snippet/warn-on-use: Fix indentation. > tests: test-update-copyright.sh: remove unnecessary "rm" commands > maint.mk: avoid sc_prohibit_always-defined_macros failure in coreutils .gnulib | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/.gnulib b/.gnulib index 41a7841..7f494c7 160000 --- a/.gnulib +++ b/.gnulib @@ -1 +1 @@ -Subproject commit 41a7841a82351f9df3e13b6199a134004d694131 +Subproject commit 7f494c7d725db4a7f3abdef09d4070725487da67 -- 1.7.4.4
