[libvirt] [RFC PATCH 0/2] Add vmgenid XML, schema, docs
by John Ferlan 22 Mar '18

22 Mar '18

Could be a v1, but figured I'd get feedback first - I have a "working example" for QEMU (supported since 2.9.0), but it's not quite ready to be fully posted. Currently only needed for windows guests, but there is some work upstream (somewhere) to make a Linux implementation. Still have to work out all the various "combinations" of when to add the vmgenid device and I think there's one combination that's not quite possible and may require some sort of set vmgenid guid value qmp command (that's being debated on qemu upstream now). To read up on the QEMU implementation, see from the top of a QEMU source tree: docs/specs/vmgenid.txt The (ahem) Microsoft details on the device is found at: http://go.microsoft.com/fwlink/?LinkId=260709 John Ferlan (2): conf: Introduce VIR_DOMAIN_DEVICE_VMGENID conf: Add VM Generation ID device docs/formatdomain.html.in | 54 ++++++++++++++ docs/schemas/domaincommon.rng | 21 ++++++ src/conf/domain_conf.c | 120 +++++++++++++++++++++++++++++- src/conf/domain_conf.h | 12 +++ src/qemu/qemu_domain.c | 1 + src/qemu/qemu_domain_address.c | 1 + src/qemu/qemu_driver.c | 6 ++ src/qemu/qemu_hotplug.c | 1 + tests/qemuxml2argvdata/vmgenid-auto.xml | 32 ++++++++ tests/qemuxml2argvdata/vmgenid.xml | 32 ++++++++ tests/qemuxml2xmloutdata/vmgenid-auto.xml | 1 + tests/qemuxml2xmloutdata/vmgenid.xml | 1 + tests/qemuxml2xmltest.c | 3 + 13 files changed, 284 insertions(+), 1 deletion(-) create mode 100644 tests/qemuxml2argvdata/vmgenid-auto.xml create mode 100644 tests/qemuxml2argvdata/vmgenid.xml create mode 120000 tests/qemuxml2xmloutdata/vmgenid-auto.xml create mode 120000 tests/qemuxml2xmloutdata/vmgenid.xml -- 2.13.6

[libvirt] [snmp PATCH 1/2] Replace U64 with struct counter64 to fix build
by Michael Corcoran 22 Mar '18

22 Mar '18

Upstream net-snmp removed the U64 typedef in 2016 as it clashed with a name in Perl, thus all usages of U64 must be replaced by struct counter64 to compile against recent versions of net-snmp. The replacements were made by hand, while referencing diff with new source generated by the mib2c tool. net-snmp have a mib2c-update tool which supposedly assists with updating existing (modified) source code but I was unable to get it to work.

[libvirt] [PATCH] libxl: don't hardcode scheduler weight
by Jim Fehlig 21 Mar '18

21 Mar '18

Long ago in commit dfa1e1dd53 the scheduler weight was accidentally hardcoded to 1000. Weight is a setting with no unit since it is relative to the weight of other domains. If no weight is specified, libxl defaults to 256. Instead of hardcoding the weight to 1000, honor any <shares> specified in <cputune>. libvirt's notion of shares is synonomous to libxl's scheduler weight setting. If shares is unspecified, defer default weight setting to libxl. Removing the hardcoded weight required some test fixup. While at it, add an explicit test for <shares> conversion to scheduler weight. Signed-off-by: Jim Fehlig <jfehlig(a)suse.com> --- Honoring <shares> specified by the user is certainly desirable, but I'm not sure about changing the default weight. One problematic scenario that came to mind: Several domains started by pre-patch libvirtd with weight=1000, update libvirtd with patch, start more domains with weight=256. The pre-patch domains unknowingly have a weight nearly 4 times that of post-patch domains. src/libxl/libxl_conf.c | 4 +- tests/libxlxml2domconfigdata/basic-hvm.json | 2 +- tests/libxlxml2domconfigdata/basic-pv.json | 2 +- tests/libxlxml2domconfigdata/cpu-shares-hvm.json | 89 ++++++++++++++++++++++ tests/libxlxml2domconfigdata/cpu-shares-hvm.xml | 39 ++++++++++ tests/libxlxml2domconfigdata/moredevs-hvm.json | 2 +- tests/libxlxml2domconfigdata/multiple-ip.json | 2 +- .../libxlxml2domconfigdata/variable-clock-hvm.json | 2 +- tests/libxlxml2domconfigdata/vnuma-hvm.json | 2 +- tests/libxlxml2domconfigtest.c | 1 + 10 files changed, 138 insertions(+), 7 deletions(-) diff --git a/src/libxl/libxl_conf.c b/src/libxl/libxl_conf.c index dcd46873c..e40145cfa 100644 --- a/src/libxl/libxl_conf.c +++ b/src/libxl/libxl_conf.c @@ -366,7 +366,9 @@ libxlMakeDomBuildInfo(virDomainDefPtr def, } } -

So far users added manual rules for most of these uncommon devices, but recent changes made some of the callbacks mandatory for hotplug so we should take shot at implementing them as those callbacks as well as for the initial start of a guest via virt-aa-helper. *Updates since v1* - Set(Memory|Input)Label: remove seclabel check already done in reload_profile - virt-aa-helper: check pointers before accessing them - add tests for new virt-aa-helper supported xml elements - extend tests to check for expected content (new patch in series) *Updates since v2* - Restore(Memory|Input)Label: drop secdef/relabel check - Set(Memory|Input)Label: check more pointers to be valid before using them Christian Ehrhardt (5): security, apparmor: add (Set|Restore)MemoryLabel security, apparmor: add (Set|Restore)InputLabel virt-aa-helper: generate rules for passthrough input devices virt-aa-helper: generate rules for nvdimm memory virt-aa-helper: test: check for expected profile content src/security/security_apparmor.c | 94 ++++++++++++++++++++++++++++++++++++++++ src/security/virt-aa-helper.c | 16 +++++++ tests/virt-aa-helper-test | 88 ++++++++++++++++++++++--------------- 3 files changed, 164 insertions(+), 34 deletions(-) -- 2.7.4

[libvirt] [PATCH] travis: skip builds on -maint branches
by Daniel P. Berrangé 21 Mar '18

21 Mar '18

For patches pushed upstream we want builds run on master branch, but don't want them run on the -maint branches, as we are not keeping the .travis.yml file on stable branches updated wrt latest needs of travis CI platforms. We can't just whitelist 'master' though, because that will prevent developers triggering their own private travis builds. So we just blacklist *-maint, since developers will typically use named feature branches for any work. Signed-off-by: Daniel P.
