[libvirt] [PATCH v2] qemu: Report the offset from host UTC for RTC_CHANGE event
by Osier Yang 06 Jun '13

06 Jun '13

https://bugzilla.redhat.com/show_bug.cgi?id=964177 Though both libvirt and QEMU's document say RTC_CHANGE returns the offset from the host UTC, qemu actually returns the offset from the specified date instead when specific date is provided (-rtc base=$date). It's not safe for qemu to fix it in code, it worked like that for 3 years, changing it now may break other QEMU use cases. What qemu tries to do is to fix the document: http://lists.gnu.org/archive/html/qemu-devel/2013-05/msg04782.html And in libvirt side, instead of reply on the qemu, this convert the offset returned from qemu to the offset from host UTC, by: /* * a: the offset from qemu RTC_CHANGE event * b: The specified date (-rtc base=$date) * c: the host date when libvirt gets the RTC_CHANGE event * offset: What libvirt will report */ offset = a + (b - c); The specified date (-rtc base=$date) is recorded in clock's def as an internal only member (may be useful to exposed outside?). Internal only XML tag "starttime" is introduced to not lose the domain process's starttime after libvirt restarting/reloading: <clock offset='variable' adjustment='304' basis='utc' starttime='1370423588'/> --- src/conf/domain_conf.c | 27 +++++++++++++++++++++++---- src/conf/domain_conf.h | 3 +++ src/qemu/qemu_command.c | 3 +++ src/qemu/qemu_process.c | 13 +++++++++++++ 4 files changed, 42 insertions(+), 4 deletions(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index a16ebd1..7773abf 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -96,6 +96,7 @@ typedef enum { VIR_DOMAIN_XML_INTERNAL_PCI_ORIG_STATES = (1<<18), VIR_DOMAIN_XML_INTERNAL_ALLOW_ROM = (1<<19), VIR_DOMAIN_XML_INTERNAL_ALLOW_BOOT = (1<<20), + VIR_DOMAIN_XML_INTERNAL_STARTTIME = (1 << 21) } virDomainXMLInternalFlags; VIR_ENUM_IMPL(virDomainTaint, VIR_DOMAIN_TAINT_LAST, @@ -11193,6 +11194,16 @@ virDomainDefParseXML(xmlDocPtr xml, break; } + if (def->clock.offset == VIR_DOMAIN_CLOCK_OFFSET_VARIABLE && + flags & VIR_DOMAIN_XML_INTERNAL_STARTTIME) { + if (virXPathULongLong("number(./clock/@starttime)", ctxt, + &def->clock.data.variable.starttime) < 0) { + virReportError(VIR_ERR_XML_ERROR, "%s", + _("invalid starttime")); + goto error; + } + } + if ((n = virXPathNodeSet("./clock/timer", ctxt, &nodes)) < 0) goto error; @@ -15788,7 +15799,8 @@ virDomainResourceDefFormat(virBufferPtr buf, verify(((VIR_DOMAIN_XML_INTERNAL_STATUS | VIR_DOMAIN_XML_INTERNAL_ACTUAL_NET | - VIR_DOMAIN_XML_INTERNAL_PCI_ORIG_STATES) + VIR_DOMAIN_XML_INTERNAL_PCI_ORIG_STATES | + VIR_DOMAIN_XML_INTERNAL_STARTTIME) & DUMPXML_FLAGS) == 0); /* This internal version can accept VIR_DOMAIN_XML_INTERNAL_*, @@ -15810,7 +15822,8 @@ virDomainDefFormatInternal(virDomainDefPtr def, virCheckFlags(DUMPXML_FLAGS | VIR_DOMAIN_XML_INTERNAL_STATUS | VIR_DOMAIN_XML_INTERNAL_ACTUAL_NET | - VIR_DOMAIN_XML_INTERNAL_PCI_ORIG_STATES, + VIR_DOMAIN_XML_INTERNAL_PCI_ORIG_STATES | + VIR_DOMAIN_XML_INTERNAL_STARTTIME, -1); if (!(type = virDomainVirtTypeToString(def->virtType))) { @@ -16208,6 +16221,10 @@ virDomainDefFormatInternal(virDomainDefPtr def, virBufferAsprintf(buf, " adjustment='%lld' basis='%s'", def->clock.data.variable.adjustment, virDomainClockBasisTypeToString(def->clock.data.variable.basis)); + + if (flags & VIR_DOMAIN_XML_INTERNAL_STARTTIME) + virBufferAsprintf(buf, " starttime='%llu'", + def->clock.data.variable.starttime); break; case VIR_DOMAIN_CLOCK_OFFSET_TIMEZONE: virBufferEscapeString(buf, " timezone='%s'", def->clock.data.timezone); @@ -16586,7 +16603,8 @@ virDomainSaveStatus(virDomainXMLOptionPtr xmlopt, unsigned int flags = (VIR_DOMAIN_XML_SECURE | VIR_DOMAIN_XML_INTERNAL_STATUS | VIR_DOMAIN_XML_INTERNAL_ACTUAL_NET | - VIR_DOMAIN_XML_INTERNAL_PCI_ORIG_STATES); + VIR_DOMAIN_XML_INTERNAL_PCI_ORIG_STATES | + VIR_DOMAIN_XML_INTERNAL_STARTTIME); int ret = -1; char *xml; @@ -16674,7 +16692,8 @@ virDomainObjListLoadStatus(virDomainObjListPtr doms, if (!(obj = virDomainObjParseFile(statusFile, caps, xmlopt, expectedVirtTypes, VIR_DOMAIN_XML_INTERNAL_STATUS | VIR_DOMAIN_XML_INTERNAL_ACTUAL_NET | - VIR_DOMAIN_XML_INTERNAL_PCI_ORIG_STATES))) + VIR_DOMAIN_XML_INTERNAL_PCI_ORIG_STATES | + VIR_DOMAIN_XML_INTERNAL_STARTTIME))) goto error; virUUIDFormat(obj->def->uuid, uuidstr); diff --git a/src/conf/domain_conf.h b/src/conf/domain_conf.h index 3a71d6c..cca92b4 100644 --- a/src/conf/domain_conf.h +++ b/src/conf/domain_conf.h @@ -1767,6 +1767,9 @@ struct _virDomainClockDef { struct { long long adjustment; int basis; + + /* Store the start time of guest process, internal only */ + unsigned long long starttime; } variable; /* Timezone name, when diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index c4a162a..9254525 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -5518,6 +5518,9 @@ qemuBuildClockArgStr(virDomainClockDefPtr def) now += def->data.variable.adjustment; gmtime_r(&now, &nowbits); + /* Store the starttime of qemu process */ + def->data.variable.starttime = now; + virBufferAsprintf(&buf, "base=%d-%02d-%02dT%02d:%02d:%02d", nowbits.tm_year + 1900, nowbits.tm_mon + 1, diff --git a/src/qemu/qemu_process.c b/src/qemu/qemu_process.c index d4fd4fb..39c62b3 100644 --- a/src/qemu/qemu_process.c +++ b/src/qemu/qemu_process.c @@ -796,6 +796,19 @@ qemuProcessHandleRTCChange(qemuMonitorPtr mon ATTRIBUTE_UNUSED, virQEMUDriverConfigPtr cfg = virQEMUDriverGetConfig(driver); virObjectLock(vm); + + /* QEMU's RTC_CHANGE event returns the offset from the specified + * date instead of the host UTC if a specific date is provided + * (-rtc base=$date).

[libvirt] Serial port creation issue
by arvind viswanathan 05 Jun '13

05 Jun '13

Hi, I have a serial port defined in vm config file. However after I create the vm using virsh, I notice that the serial ports I have specified translate to -chardev when kvm-quemu is called. I am having trouble accessing the vm if it is configured as a chardev with isserial option. If i can directly call the qemu with -serial, I can access the vm, thanks arvind

[libvirt] [PATCH] qemu: Reformat listen address prior checking
by Michal Privoznik 05 Jun '13

05 Jun '13

Currently, a listen address for a SPICE server can be specified. Later, when the domain is migrated, we need to relocate the graphics which involves telling new destination to the SPICE server. However, we can't just assume the listen address is the new location, because the listen address can be ANYCAST (0.0.0.0 for IPv4, :: for IPv6). In which case, we want to pass the remote hostname. But there are some troubles with ANYCAST. In both IPv4 and IPv6 it has many ways for specifying such address. For instance, in IPv4: 0, 0.0, 0.0.0, 0.0.0.0. The number of variations gets bigger in IPv6 world. Hence, in order to check for ANYCAST address sanely, we should take the provided listen address, parse it and format back in it's full form. Which is exactly what this patch does. --- src/qemu/qemu_migration.c | 18 +++++++++++++++++- tests/sockettest.c | 24 ++++++++++++++++++++++++ 2 files changed, 41 insertions(+), 1 deletion(-) diff --git a/src/qemu/qemu_migration.c b/src/qemu/qemu_migration.c index 7aa0476..3ca3f32 100644 --- a/src/qemu/qemu_migration.c +++ b/src/qemu/qemu_migration.c @@ -1735,42 +1735,58 @@ static int qemuDomainMigrateGraphicsRelocate(virQEMUDriverPtr driver, virDomainObjPtr vm, qemuMigrationCookiePtr cookie) { qemuDomainObjPrivatePtr priv = vm->privateData; int ret; char *listenAddress; + virSocketAddr addr; + bool reformatted = false; if (!cookie) return 0; if (!cookie->graphics) return 0; /* QEMU doesn't support VNC relocation yet, so * skip it to avoid generating an error */ if (cookie->graphics->type != VIR_DOMAIN_GRAPHICS_TYPE_SPICE) return 0; listenAddress = cookie->graphics->listen; + + /* Okay, here's the magic: some mgmt applications set bare '0' as listen + * address.
