[libvirt] Improve the reliability of pty path parsing
by Matthew Booth 14 Dec '09

14 Dec '09

The following are improve the reliability of libvirt's mapping of character devices to pty paths. When qemu starts up it will output one or more lines of the form: char device redirected to /dev/pts/5 Note that the character device this refers to is not indicated, so the only way to match this up is by knowing the order they're written in. This is not a well-defined interface, and is therefore voodoo-magic. The current code works against current versions of QEMU. However, when using the -chardev syntax of newer QEMU, the output order changes (putting chardev first). The first patch works by making all character devices use -chardev if it's available. As well as being a better syntax, this makes the output of the redirection lines again match the order they're specified on the command line. The second patch uses this ordering to parse the ptys for channel devices from the log output. The third patch (almost) obsoletes the log output parsing method. If QEMU's monitor supports 'info chardev', this gives structured information about character devices, including pty mappings. The log output parsing method is still required because QEMU may not support info chardev, and because the monitor itself can be on a pty. The danger of the third patch is that it will fix errors in the log output parsing code, which may then bitrot. Matt

[libvirt] [PATCH] Suppress cgroup error message on sucess in qemudStartVMDaemon
by Ryota Ozaki 14 Dec '09

14 Dec '09

Even if qemudStartVMDaemon suceeds, an error is logged such as 'qemuRemoveCgroup:1778 : internal error Unable to find cgroup for'. This is because qemudStartVMDaemon calls qemuRemoveCgroup to ensure that old cgroup does not remain. This workaround makes sense but leaving an error message may confuse users. This patch simply adds an option to suppress the error log if not needed. --- src/qemu/qemu_driver.c | 16 +++++++++------- 1 files changed, 9 insertions(+), 7 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index a4a87ac..84ee942 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -1763,7 +1763,8 @@ cleanup: static int qemuRemoveCgroup(virConnectPtr conn, struct qemud_driver *driver, - virDomainObjPtr vm) + virDomainObjPtr vm, + int quiet) { virCgroupPtr cgroup; int rc; @@ -1773,9 +1774,10 @@ static int qemuRemoveCgroup(virConnectPtr conn, rc = virCgroupForDomain(driver->cgroup, vm->def->name, &cgroup, 0); if (rc != 0) { - qemudReportError(conn, NULL, NULL, VIR_ERR_INTERNAL_ERROR, - _("Unable to find cgroup for %s\n"), - vm->def->name); + if (!quiet) + qemudReportError(conn, NULL, NULL, VIR_ERR_INTERNAL_ERROR, + _("Unable to find cgroup for %s\n"), + vm->def->name); return rc; } @@ -2142,7 +2144,7 @@ static int qemudStartVMDaemon(virConnectPtr conn, return -1; /* Ensure no historical cgroup for this VM is lieing around bogus settings */ - qemuRemoveCgroup(conn, driver, vm); + qemuRemoveCgroup(conn, driver, vm, 1); if ((vm->def->ngraphics == 1) && vm->def->graphics[0]->type == VIR_DOMAIN_GRAPHICS_TYPE_VNC && @@ -2327,7 +2329,7 @@ cleanup: VIR_FREE(vm->def->seclabel.label); VIR_FREE(vm->def->seclabel.imagelabel); } - qemuRemoveCgroup(conn, driver, vm); + qemuRemoveCgroup(conn, driver, vm, 0); if ((vm->def->ngraphics == 1) && vm->def->graphics[0]->type == VIR_DOMAIN_GRAPHICS_TYPE_VNC && vm->def->graphics[0]->data.vnc.autoport) @@ -2416,7 +2418,7 @@ static void qemudShutdownVMDaemon(virConnectPtr conn, qemuDomainReAttachHostDevices(conn, driver, vm->def); retry: - if ((ret = qemuRemoveCgroup(conn, driver, vm)) < 0) { + if ((ret = qemuRemoveCgroup(conn, driver, vm, 0)) < 0) { if (ret == -EBUSY && (retries++ < 5)) { usleep(200*1000); goto retry; -- 1.6.5.2

[libvirt] Having some issue with : virConnectRef
by anuj rampal 14 Dec '09

14 Dec '09

Hi, Im trying to call libvirt functions from a widows machine. The client version i'm using is 0.6.1. My application is a multi-Threaded application. This is the way my application works: 1. I connect to Libvirt using "virConnectOpen". (this done only once when my application starts). 2. For funther interaction with libvirt i just call "virConnectRef" and then i call some other function like "virNodeGetInfo". 3. Then i call "virConnectClose". Now my understanding is for every "virConnectRef" call there has to be a corrosponding "virConnectClose". In my application call to number of calls to "virConnectClose" is always equal to "virConnectRef". and "virConnectClose" corrosponding to "virConnectOpen" is called when the application is closed. So connection to libvirt should always be there till the time my application is running. But what is happening is, even if i call "virConnectRef" twice, a single call to "virConnectClose" closes the connection with libvirt. Is there anything that im doing wrong here...?? Regards Anuj

[libvirt] Toward the next 0.7.5 release
by Daniel Veillard 11 Dec '09

11 Dec '09

The last release was 0.7.4 on Nov 20, so if we try to keep with the one month release cycle, we would end up with a release on Friday 25, but I really plan on celebrating Chrismas with my familly that day instead of spending time in front of a computer (I plan to roast a pig and that requires all my attention :-) I would prefer to not wait too much, as there were some serious locking bugs in 0.7.4, and I would rather not wait until the end of the vacations either. So I'm tempted to push on Wed 23, with possibly a smaller timeframe for the bug fixes only window. We didn't (yet!) introduce major changes inside (except maybe for the VirtualBox driver and early bug have been reported) and Matthias has been debugging seriously with the TCK so things should be in relatively good shape out of git. So my plan right nw would be to enter freeze, next Friday the 18th and push the release 0f 0.7.5 on the 23rd. So send those patches along and if we forgot to ACK patches please raise our attention about them, thanks !
