[libvirt] Python setInterfaceParameters function broken
by Brian Rak 18 Mar '14

18 Mar '14

I've been trying to use domain.setInterfaceParameters, and I'm finding it's throwing the mysterious error: libvirt.libvirtError: argument unsupported: parameter '' not supported Enabling debug mode in libvirt reveals this: 2014-03-17 18:41:33.780+0000: 16927: debug : virDomainSetInterfaceParameters:8001 : dom=0x7f2ecc0009b0, (VM: name=SRVID8736, uuid=5121c1d6-19aa-4494-b6a7-09af270f24da), device=vnet0, params=0x7f2ecc0011f0, nparams=6, flags=0 2014-03-17 18:41:33.780+0000: 16927: debug : virDomainSetInterfaceParameters:8002 : params[""]=(uint)0 2014-03-17 18:41:33.780+0000: 16927: debug : virDomainSetInterfaceParameters:8002 : params[""]=(uint)64000 2014-03-17 18:41:33.780+0000: 16927: debug : virDomainSetInterfaceParameters:8002 : params[""]=(uint)10 2014-03-17 18:41:33.780+0000: 16927: debug : virDomainSetInterfaceParameters:8002 : params[""]=(uint)64000 2014-03-17 18:41:33.780+0000: 16927: debug : virDomainSetInterfaceParameters:8002 : params[""]=(uint)0 2014-03-17 18:41:33.780+0000: 16927: debug : virDomainSetInterfaceParameters:8002 : params[""]=(uint)0 (irreverent lines trimmed) Which ultimately led me to setPyVirTypedParameter lines 200-202. These don't seem to work properly. I added some debugging: strncpy(temp->field, keystr, sizeof(*temp->field) - 1); temp->field[sizeof(*temp->field) - 1] = '\0'; DEBUG("current key name in: %s, out: %s field size: %i\n", keystr, temp->field, sizeof(*temp->field) - 1); temp->type = params[i].type; which was displaying: current key name in: outbound.peak, out: field size: 0 current key name in: inbound.peak, out: field size: 0 current key name in: inbound.burst, out: field size: 0 current key name in: inbound.average, out: field size: 0 current key name in: outbound.average, out: field size: 0 current key name in: outbound.burst, out: field size: 0 I am not good enough in C to determine what exactly the correct fix is here. It seems like nothing that used this function could have ever worked. My trivial patch was: --- a/python27-libvirt/libvirt-python-1.2.2/libvirt-override.c +++ b/python27-libvirt/libvirt-python-1.2.2/libvirt-override.c @@ -197,8 +197,8 @@ setPyVirTypedParameter(PyObject *info, goto cleanup; } - strncpy(temp->field, keystr, sizeof(*temp->field) - 1); - temp->field[sizeof(*temp->field) - 1] = '\0'; + strncpy(temp->field, keystr, VIR_TYPED_PARAM_FIELD_LENGTH - 1); + temp->field[VIR_TYPED_PARAM_FIELD_LENGTH - 1] = '\0'; temp->type = params[i].type; VIR_FREE(keystr); I am not sure if this is the best approach here. This change definitely fixes the issue, and allows setInterfaceParameters to actually execute successfully. I am not comfortable enough with my understanding of the issue to actually submit this as a patch though. Is this something that someone else can take a look at or fix? My trivial test script that was showing the issue: import libvirt conn = libvirt.open(None) if conn == None: print 'Failed to connect'; sys.exit(1) for id in conn.listDomainsID(): dom = conn.lookupByID(id) if dom == None: continue params = dom.interfaceParameters('vnet0', 0) print params dom.setInterfaceParameters('vnet0', params, 0)

[libvirt] [PATCH 0/7] POC: Saner firewall integration
by Daniel P. Berrange 17 Mar '14

17 Mar '14

We currently have three areas of code which deal with firewall changes. The bridge driver's iptables usage, the QEMU driver's ebtables usage for mac filters and the nwfilter code. These all directly invoke the iptables/ebtables commands or in the case of nwfilter invoke horrible generated shell scripts. The latter in particular has always been an unpleasant design choice, but it has been made much worse by support for firewalld. We are now invoking firewall-cmd just in order to make a DBus method call to firewalld which then invokes the real *tables commands. This has a notable performance impact. This proof of concept series introduces a new virFirewallPtr object for encapsulating all firewall changes. It provides a transactional API for making firewall changes, so the caller can define a set of rules which must either all succeed or all fail, along with a set of rules to perform rollback upon fail. It will either execute *tables commands directly or will call the DBus method for firewalld directly. The upshot is that it will become possible to unit test all the firewall code much more easily, instead of having to rely on integration testing that we currently have for nwfilter. We will also have much improved performance by avoiding the firewall-cmd tool and easier to understand code too. In this series I've only done the core infrastructure and the conversion of viriptables + virebtables source files. The work on nwfilter is a bigger job that I'm still working on. Daniel P. Berrange (7): Introduce a new set of helper macros for mocking symbols Create a re-usable DBus LD_PRELOAD mock library Switch systemd test to use generic dbus mock Add ability to register callback for virCommand dry run Introduce an object for managing firewall rulesets Convert bridge driver over to use new firewall APIs Convert ebtables code over to use firewall APIs include/libvirt/virterror.h | 1 + po/POTFILES.in | 1 + src/Makefile.am | 2 + src/libvirt_private.syms | 13 + src/network/bridge_driver_linux.c | 669 ++++++++++++++++---------------------- src/util/vircommand.c | 47 ++- src/util/vircommand.h | 12 +- src/util/virebtables.c | 187 +++-------- src/util/virerror.c | 1 + src/util/virfirewall.c | 653 +++++++++++++++++++++++++++++++++++++ src/util/virfirewall.h | 93 ++++++ src/util/virfirewallpriv.h | 45 +++ src/util/viriptables.c | 634 ++++++++++++++++-------------------- src/util/viriptables.h | 114 ++++--- tests/Makefile.am | 30 +- tests/testutils.c | 18 +- tests/virfirewalltest.c | 619 +++++++++++++++++++++++++++++++++++ tests/virkmodtest.c | 8 +- tests/virmock.h | 298 +++++++++++++++++ tests/virmockdbus.c | 64 ++++ tests/virnetdevbandwidthtest.c | 3 +- tests/virsystemdmock.c | 139 -------- tests/virsystemdtest.c | 89 ++++- 23 files changed, 2626 insertions(+), 1114 deletions(-) create mode 100644 src/util/virfirewall.c create mode 100644 src/util/virfirewall.h create mode 100644 src/util/virfirewallpriv.h create mode 100644 tests/virfirewalltest.c create mode 100644 tests/virmock.h create mode 100644 tests/virmockdbus.c delete mode 100644 tests/virsystemdmock.c -- 1.8.5.3

[libvirt] [PATCH 0/7 v2] Remove overhead of disabled logging calls
by Daniel P. Berrange 17 Mar '14

17 Mar '14

A v2 of https://www.redhat.com/archives/libvir-list/2014-March/msg00124.html Looking at the performance of the libvirtd event loop when used with libvirt sandbox and apps which do lots of I/O I discovered that a huge amount of time was being spent in our logging APIs making the event loop quite poor at dealing with frequently firing poll events for small data sizes. To track this down I created the following short demo program which simulates a libvirtd event loop thread, watching 500 FDs (eg 500 QEMU or LXC console or monitor FDs). In the test no logging outputs are enabled, so ideally the log overhead would be near zero. Running the demo for 51200 iterations initially took 1 minute 40 seconds. oprofile traces show that in this test run the logging APIs were totally dominant in CPU time, over the work done in the event loop. Note the demo program's FD handler doesn't actually do any work, so this is showing the worst case behaviour, but it is none-the-less a good illustration of the loggin overhead. After refactoring the logging code, the overhead of logging calls when no outputs are enabled is reduced to a single function call which does 2 integer comparisons without any mutex locks. The demo program now completes in 3.3 seconds. IOW, 97% of the original CPU time for the demo was consumed by the logging APIs ! The main feature we loose in this series is the global logging buffer. This ring buffer currently collects all log mesages regardless of log filter settings, and dumps them to stderr upon crash of libvirtd. As the amount of logging code in libvirt has grown, the signal/noise ratio of data in the global log buffer has gone down significantly. Whenever libvirtd crashes, my first reaction to ask the reporter to reproduce with a specifically tailored set of log filters set. Thus, IMHO, the global log buffer is no longer a compelling enough feature to justify its significant performance overhead. Rather than remove it entirely though, I've changed it in two parts. The first patch removes the overhead of it, but leaves a more tailored verson of it still present. This removes the contribution it makes to performance overheads. The last patch, which is not performance relevant, simply deletes the rest of the global log buffer entirely. I'm mostly ambivalent on whether to apply patch 7 or not. IMHO the global log buffer is mostly useless once patch 1 is applied, but if people think it is worth keeping it, patch 7 can be dropped and I won't mind. The demo program used is $ cat demo.c #include <libvirt/libvirt.h> #include <unistd.h> #include <stdio.h> static void ignore(int handle, int fd, int events, void *opaque) { // nada } #define STEPS (1024 * 5) #define ITERATIONS (STEPS * 10) #define NFILES 500 int main(int argc, char **argv) { int fds[NFILES][2]; int i; virEventRegisterDefaultImpl(); for (i = 0 ; i < NFILES ; i++) { char c = '0'; if (pipe(fds[i]) < 0) { perror("pipe"); return -1; } if (write(fds[i][1], &c, 1) < 0) return -1; virEventAddHandle(fds[i][0], VIR_EVENT_HANDLE_READABLE, ignore, NULL, NULL); } for (i = 0 ; i < ITERATIONS ; i++) { if (!(i % STEPS)) fprintf(stderr, "."); virEventRunDefaultImpl(); } return 0; } Simply compile & run it with no args $ gcc -Wall `pkg-config --cflags --libs libvirt` -o demo demo.c $ time ./demo .......... real 1m39.981s user 1m34.894s sys 0m4.851s Now make it use the newly compiled libvirt version $ export LD_LIBRARY_PATH=`pwd`/src/.libs $ time ./demo .......... real 0m3.316s user 0m2.896s sys 0m0.412s 97% execution time removed ! Daniel P. Berrange (7): Reduce performance overhead of the global log buffer Refactor code that skips logging of error messages Move dtrace probe macros into separate header file Turn virLogSource into a struct instead of an enum Add virLogSource variables to all source files Switch to filtering based on log source name instead of filename Remove global log buffer feature entirely cfg.mk | 3 + daemon/libvirtd-config.c | 5 +- daemon/libvirtd-config.h | 1 -

[libvirt] [PATCH] bhyve: add console support through nmdm device
by Roman Bogorodskiy 17 Mar '14

17 Mar '14

Some additional info on nmdm devices that probably doesn't fit commit message. Man page: http://www.freebsd.org/cgi/man.cgi?query=nmdm&sektion=4 To use this device, we pass device name like '/dev/nmdmNA' to bhyve. Device is created automatically when bhyve accesses it. The pair device name is always '/dev/nmdmNB' which is used to provide console support. Even though this patch doesn't directly depend on virFDStreamOpenPTY() addition patch: https://www.redhat.com/archives/libvir-list/2014-March/msg00582.html it's not much useful without it because of mangled console output.
