[libvirt] cgroup memoryinfo handling
by Zvi Dubitzky 25 Mar '11

25 Mar '11

Hi 1) Daniel Smith of IBM wrote (2008) code for implementing 'virsh schedinfo' in src/util/cgroup.c He also added some code for cgroup memory subsystem (util/cgroup.c/ virCgroupSetMemoryHardLimit () etc.), I see also src/qemu_driver.c/qemuDomainSetMemoryParameters() But that seems not being invoked . I am looking at libvirt-0.8.8 2) Is anybody handling/completing this piece of code and are you libvirt guys interested in us completing it because we might find usage for that kind of 'virsh meminfo' command using cgroups . thanks Zvi Dubitzky Email:dubi@il.ibm.com

[libvirt] [PATCH] unlock the monitor when unwatching the monitor
by Wen Congyang 25 Mar '11

25 Mar '11

Steps to reproduce this bug: # virsh qemu-monitor-command domain 'cpu_set 2 online' --hmp The domain has 2 cpus, and we try to set the third cpu online. The qemu crashes, and this command will hang. The reason is that the refs is not 1 when we unwatch the monitor. We lock the monitor, but we do not unlock it. So virCondWait() will be blocked.

[libvirt] [PATCHv6 1/3] libvirt/qemu - support persistent modification of devices.
by KAMEZAWA Hiroyuki 24 Mar '11

24 Mar '11

Thank you for comments. This is a rebased/fixed one. = >From 5858b9d6b33a9d917576f6179be13a306272ff45 Mon Sep 17 00:00:00 2001 From: KAMEZAWA Hiroyuki <kamezawa.hiroyu(a)jp.fujitsu.com> Date: Wed, 23 Mar 2011 17:45:12 +0900 Subject: [PATCHv6 1/3] libvirt/qemu - support persistent modification of devices. Now, qemudDomainAttachDeviceFlags() and qemudDomainDetachDeviceFlags() doesn't support VIR_DOMAIN_DEVICE_MODIFY_CONFIG. By this, virsh's at(de)tatch-device --persistent cannot modify qemu config. (Xen allows it.) This patch is a base patch for adding support of devices in step by step manner. Following patches will add some device support.

[libvirt] [libvirt-snmp][PATCH v3 0/3] Add SNMP trap/notification support
by Michal Privoznik 24 Mar '11

24 Mar '11

The third version with micro-version number change. Finally, we have a proof-of-concept implementation of SNMP trap. Two new files were first generated using mib2c then edited, so be careful when re-generating them. Destination of traps is defined in snmpd.conf (trap2sink), and to receive them snmptrapd must be configured and up. The idea behind is - create a thread in which we poll for domain events. Once we receive event notification, we just fire up trap sending. Michal Privoznik (3): Add notification-type object to libvirt MIB Create functions to fill in and send notification packets. Add SNMP trap/notification support.

[libvirt] [PATCH] logging: fix off-by-one bug
by Eric Blake 24 Mar '11

24 Mar '11

Valgrind caught that our log wrap-around was going 1 past the end. Regression introduced in commit b16f47a; previously the buffer was static and size+1 bytes, but now it is dynamic and exactly size bytes. * src/util/logging.c (virLogStr): Don't write past end of log. --- An alternative would be to malloc one larger; but since the log is likely to be a page size multiple and large enough to be worth malloc using mmap, going one larger is likely to waste the bulk of a page. Also, I like always NUL-terminating the current end of the log (without including that NUL in the log length). src/util/logging.c | 4 ++-- 1 files changed, 2 insertions(+), 2 deletions(-) diff --git a/src/util/logging.c b/src/util/logging.c index b972f8a..f4910ad 100644 --- a/src/util/logging.c +++ b/src/util/logging.c @@ -326,7 +326,7 @@ static void virLogStr(const char *str, int len) { return; if (len <= 0) len = strlen(str); - if (len > virLogSize) + if (len >= virLogSize) return; virLogLock(); @@ -336,13 +336,13 @@ static void virLogStr(const char *str, int len) { if (virLogEnd + len >= virLogSize) { tmp = virLogSize - virLogEnd; memcpy(&virLogBuffer[virLogEnd], str, tmp); - virLogBuffer[virLogSize] = 0; memcpy(&virLogBuffer[0], &str[tmp], len - tmp); virLogEnd = len - tmp; } else { memcpy(&virLogBuffer[virLogEnd], str, len); virLogEnd += len; } + virLogBuffer[virLogEnd] = 0; /* * Update the log length, and if full move the start index */ -- 1.7.4
