[libvirt] [PATCH] Fix python error reporting for some storage operations
by Cole Robinson 07 Mar '25

07 Mar '25

In the python bindings, all vir* classes expect to be passed a virConnect object when instantiated. Before the storage stuff, these classes were only instantiated in virConnect methods, so the generator is hardcoded to pass 'self' as the connection instance to these classes. Problem is there are some methods that return pool or vol instances which aren't called from virConnect: you can lookup a storage volume's associated pool, and can lookup volumes from a pool. In these cases passing 'self' doesn't give the vir* instance a connection, so when it comes time to raise an exception crap hits the fan. Rather than rework the generator to accomodate this edge case, I just fixed the init functions for virStorage* to pull the associated connection out of the passed value if it's not a virConnect instance.

[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] Segmentation fault when shutting down VMs
by Thomas Treutner 10 Dec '09

10 Dec '09

Hi, I'm facing another problem with latest git. This happens regularly when shutting down VM(s): http://pastebin.com/m4ef1d93f It doesn't depend on which or how many VM is/are shut down, or if I have a VNC connection to a VM that is shutting down. Sometimes after a segv, I get this: http://pastebin.com/m5260bf21 It seems to me that libvirt tries to query a qemu monitor that is no longer alive? kr,tom

[libvirt] [PATCH] Add virBufferFreeAndReset() and replace free()
by Matthias Bolte 09 Dec '09

09 Dec '09

Replace free(virBufferContentAndReset()) with virBufferFreeAndReset(). Update documentation and replace all remaining calls to free() with calls to VIR_FREE(). Also add missing calls to virBufferFreeAndReset() and virReportOOMError() in OOM error cases. --- HACKING | 5 ++- daemon/libvirtd.c | 6 ++-- docs/hacking.html.in | 7 ++-- src/conf/capabilities.c | 4 ++- src/conf/domain_conf.c | 11 +++--- src/conf/interface_conf.c | 5 +-- src/conf/network_conf.c | 4 +-- src/conf/node_device_conf.c | 4 +-- src/conf/secret_conf.c | 4 +-- src/conf/storage_conf.c | 8 ++--- src/esx/esx_driver.c | 3 ++ src/esx/esx_vi.c | 10 ++--- src/esx/esx_vi_methods.c | 68 +++++++++--------------------------- src/esx/esx_vmx.c | 11 +----- src/libvirt_private.syms | 1 + src/node_device/node_device_udev.c | 1 + src/opennebula/one_conf.c | 3 +- src/openvz/openvz_conf.c | 8 +++-- src/openvz/openvz_driver.c | 3 +- src/phyp/phyp_driver.c | 5 +-- src/qemu/qemu_conf.c | 39 ++++++++++++++------- src/qemu/qemu_driver.c | 5 ++- src/security/virt-aa-helper.c | 9 +++-- src/storage/storage_backend.c | 3 +- src/uml/uml_conf.c | 4 +-- src/util/buf.c | 13 +++++++ src/util/buf.h | 1 + src/util/conf.c | 5 ++- src/util/logging.c | 8 +++- src/util/qparams.c | 1 + src/xen/xend_internal.c | 14 +++++--- src/xen/xm_internal.c | 19 +++++----- tools/virsh.c | 4 +- 33 files changed, 146 insertions(+), 150 deletions(-) diff --git a/HACKING b/HACKING index 548e2a0..3fb1113 100644 --- a/HACKING +++ b/HACKING @@ -293,10 +293,11 @@ eg typical usage is as follows: ... virBufferAddLit(&buf, "</domain>\n");
