[libvirt] [PATCH] conf: fix parsing 'cmd_per_lun' and 'max_sectors'
by Wang Rui 14 Aug '14

14 Aug '14

From: Mo yuxiang <moyuxiang(a)huawei.com> commit d9504941 introduces two new attributes "cmd_per_lun" and "max_sectors" same with the names QEMU uses for virtio-scsi. But the case of parsing them is not exact. Change to parse them if controller has "driver" element.

[libvirt] [PATCH] qemu: Issue rtc_reset_reinjection command after guest-set-time
by Michal Privoznik 14 Aug '14

14 Aug '14

An advice appeared there on the qemu-devel list [1]. When a domain is suspended and then resumed guest kernel is not aware of this. So we've introduced virDomainSetTime API that resets the time within guest using qemu-ga. On the other hand, qemu itself is trying to make RTC beat faster to catch the difference. But if we don't tell qemu that guest's time was reset via the other method, both mechanisms are applied resulting in again wrong guest time. In order to avoid summing both corrections we need to tell qemu that it should not use the RTC injection if the guest time is set via guest agent. 1: http://www.mail-archive.com/qemu-devel@nongnu.org/msg236435.html Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com> --- src/qemu/qemu_driver.c | 10 ++++++++++ src/qemu/qemu_monitor.c | 33 +++++++++++++++++++++++++++++++++ src/qemu/qemu_monitor.h | 2 ++ src/qemu/qemu_monitor_json.c | 21 +++++++++++++++++++++ src/qemu/qemu_monitor_json.h | 2 ++ 5 files changed, 68 insertions(+) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index b6219ba..bdfd155 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -16879,6 +16879,16 @@ qemuDomainSetTime(virDomainPtr dom, rv = qemuAgentSetTime(priv->agent, seconds, nseconds, rtcSync); qemuDomainObjExitAgent(vm); + if (!virDomainObjIsActive(vm)) { + virReportError(VIR_ERR_OPERATION_INVALID, + "%s", _("domain is not running")); + goto endjob; + } + + qemuDomainObjEnterMonitor(driver, vm); + rv = qemuMonitorRTCResetReinjection(priv->mon); + qemuDomainObjExitMonitor(driver, vm); + if (rv < 0) goto endjob; diff --git a/src/qemu/qemu_monitor.c b/src/qemu/qemu_monitor.c index 3d9f87b..77627bc 100644 --- a/src/qemu/qemu_monitor.c +++ b/src/qemu/qemu_monitor.c @@ -4037,3 +4037,36 @@ qemuMonitorGetGuestCPU(qemuMonitorPtr mon, return qemuMonitorJSONGetGuestCPU(mon, arch, data); } + +/** + * qemuMonitorRTCResetReinjection: + * @mon: Pointer to the monitor + * + * Issue rtc-reset-reinjection command. + * This should be used in cases where guest time is restored via + * guest agent so RTC injection is not needed (in fact it will + * confuse guest's RTC). + * + * Returns 0 on success + * -1 on error. + */ +int +qemuMonitorRTCResetReinjection(qemuMonitorPtr mon) +{ + + VIR_DEBUG("mon=%p", mon); + + if (!mon) { + virReportError(VIR_ERR_INVALID_ARG, "%s", + _("monitor must not be NULL")); + return -1; + } + + if (!mon->json) { + virReportError(VIR_ERR_OPERATION_UNSUPPORTED, "%s", + _("JSON monitor is required")); + return -1; + } + + return qemuMonitorJSONRTCResetReinjection(mon); +} diff --git a/src/qemu/qemu_monitor.h b/src/qemu/qemu_monitor.h index c3695f2..4fd6f01 100644 --- a/src/qemu/qemu_monitor.h +++ b/src/qemu/qemu_monitor.h @@ -790,6 +790,8 @@ int qemuMonitorGetGuestCPU(qemuMonitorPtr mon, virArch arch, virCPUDataPtr *data); +int qemuMonitorRTCResetReinjection(qemuMonitorPtr mon); + /** * When running two dd process and using <> redirection, we need a * shell that will not truncate files.

[libvirt] [PATCH] Always add 'console' matching the 'serial' device
by Ján Tomko 13 Aug '14

13 Aug '14

We have been formatting the first serial device also as a console device, but only if there were no other consoles. If there is a <serial> device present in the XML, but no serial <console>, or if there isn't any <console> at all but the domain definition hasn't gone through a parse->format->parse round-trip, the <console> device would not be formatted. Change the code to always add the stub device for the first serial device.

We're using sasl+gssapi+kerberos to do authentication for libvirt, including from hypervisor to hypervisor.
