[libvirt] [v6 00/10] Support cache tune in libvirt
by Eli Qiao 15 Feb '17

15 Feb '17

Addressed comment from v6 -> v5 Marcelo: * Support other APPs to operate /sys/fs/resctrl at same time Libvirt will scan /sys/fs/resctrl again before doing cache allocation. patch 10 will address this. Addressed comment from v4 -> v5: Marcelo: * Several typos * Use flock instead of virFileLock Addressed comment from v3 -> v4: Daniel & Marcelo: * Added concurrence support Addressed comment from v2 -> v3: Daniel: * Fixed coding style, passed `make check` and `make syntax-check` * Variables renaming and move from header file to c file. * For locking/mutex support, no progress. There are some discussion from mailing list, but I can not find a better way to add locking support without performance impact. I'll explain the process and please help to advice what shoud we do. VM create: 1) Get the cache left value on each bank of the host. This should be shared amount all VMs. 2) Calculate the schemata on the bank based on all created resctrl domain's schemata 3) Calculate the default schemata by scaning all domain's schemata. 4) Flush default schemata to /sys/fs/resctrl/schemata VM destroy: 1) Remove the resctrl domain of that VM 2) Recalculate default schemata 3) Flush default schemata to /sys/fs/resctrl/schemata The key point is that all VMs shares /sys/fs/resctrl/schemata, and when a VM create a resctrl domain, the schemata of that VM depends on the default schemata and all other exsited schematas. So a global mutex is reqired. Before calculate a schemata or update default schemata, libvirt should gain this global mutex. I will try to think more about how to support this gracefully in next patch set. Marcelo: * Added vcpu support for cachetune, this will allow user to define which vcpu using which cache allocation bank. <cachetune id='0' host_id=0 size='3072' unit='KiB' vcpus='0,1'/> vcpus is a cpumap, the vcpu pids will be added to tasks file * Added cdp compatible, user can specify l3 cache even host enable cdp. See patch 8. On a cdp enabled host, specify l3code/l3data by <cachetune id='0' host_id='0' type='l3' size='3072' unit='KiB'/> This will create a schemata like: L3data:0=0xff00;... L3code:0=0xff00;... * Would you please help to test if the functions work. Martin: * Xml test case, I have no time to work on this yet, would you please show me an example, would like to amend it later. This series patches are for supportting CAT featues, which also called cache tune in libvirt. First to expose cache information which could be tuned in capabilites XML. Then add new domain xml element support to add cacahe bank which will apply on this libvirt domain. This series patches add a util file `resctrl.c/h`, an interface to talk with linux kernel's system fs. There are still one TODO left: 1. Expose a new public interface to get free cache information. 2. Expose a new public interface to set cachetune lively. Some discussion about this feature support can be found from: https://www.redhat.com/archives/libvir-list/2017-January/msg00644.html Eli Qiao (10): Resctrl: Add some utils functions Resctrl: expose cache information to capabilities Resctrl: Add new xml element to support cache tune Resctrl: Add private interface to set cachebanks Qemu: Set cache banks Resctrl: enable l3code/l3data Resctrl: Make sure l3data/l3code are pairs Resctrl: Compatible mode for cdp enabled Resctrl: concurrence support Resctrl: Scan resctrl before doing cache allocation docs/schemas/domaincommon.rng | 46 ++ include/libvirt/virterror.h | 1 + po/POTFILES.in | 1 + src/Makefile.am | 1 + src/conf/capabilities.c | 56 ++ src/conf/capabilities.h | 23 + src/conf/domain_conf.c | 182 +++++++ src/conf/domain_conf.h | 19 + src/libvirt_private.syms | 11 + src/nodeinfo.c | 64 +++ src/nodeinfo.h | 1 + src/qemu/qemu_capabilities.c | 8 + src/qemu/qemu_driver.c | 6 + src/qemu/qemu_process.c | 53 ++ src/util/virerror.c | 1 + src/util/virresctrl.c | 1208 +++++++++++++++++++++++++++++++++++++++++ src/util/virresctrl.h | 88 +++ 17 files changed, 1769 insertions(+) create mode 100644 src/util/virresctrl.c create mode 100644 src/util/virresctrl.h -- 1.9.1

[libvirt] [RFC PATCH 00/16] Introduce vGPU mdev framework to libvirt
by Erik Skultety 15 Feb '17

15 Feb '17

Finally. It's here. This is the initial suggestion on how libvirt might interract with the mdev framework, currently only focussing on the non-managed devices, i.e. those pre-created by the user, since that will be revisited once we all settled on how the XML should look like, given we might not want to use the sysfs path directly as an attribute in the domain XML. My proposal on the XML is the following: <hostdev mode='subsystem' type='mdev'> <source>  <address domain='0x0000' bus='0x00' slot='0x00' function='0x00'> <uuid>vGPU_UUID<uuid> <source>  </hostdev> So the mediated device is identified by the physical parent device visible on the host and a UUID which allows us to construct the sysfs path by ourselves, which we then put on the QEMU's command line. A few remarks if you actually happen to have a machine to test this on: - right now the mediated devices are one-time use only, i.e. they have to be recreated before every machine boot - I wouldn't recommend assigning multiple vGPUs to a single domain Once this series is sorted out, we can then continue with 'managed=yes' where as Laine pointed out [1], we need to figure out how exactly should the management layer hint libvirt which vGPU type should be used for device instantiation.

Patch1 is a small improvement. Patch2 fixes a bug that is triggered when the apparmor security driver is enabled and domain config specifies a different security driver. E.g. # virsh dumpxml test | grep seclabel <seclabel type='none' model='none'/> # virsh start test error: Failed to start domain test error: An error occurred, but the cause is unknown Jim Fehlig (2): apparmor: don't overwrite error from reload_profile apparmor: don't fail on non-apparmor <seclabel> src/security/security_apparmor.c | 72 ++++++++++------------------------------ 1 file changed, 18 insertions(+), 54 deletions(-) -- 2.9.2

[libvirt] [PATCH 00/33] qemu: Detect host CPU model by asking QEMU on x86_64
by Jiri Denemark 15 Feb '17

15 Feb '17

Until now host-model CPU mode tried to enable all CPU features supported by the host CPU even if QEMU/KVM did not support them. This caused a number of issues and made host-model quite unreliable. Asking QEMU for the CPU it can provide and the current host makes host-model much more robust. This series fixes the following bugs: https://bugzilla.redhat.com/show_bug.cgi?id=1018251 https://bugzilla.redhat.com/show_bug.cgi?id=1371617 https://bugzilla.redhat.com/show_bug.cgi?id=1372581 https://bugzilla.redhat.com/show_bug.cgi?id=1404627 https://bugzilla.redhat.com/show_bug.cgi?id=870071 In addition to that, the following bug should be mostly limited to cases when an unsupported feature is explicitly requested: https://bugzilla.redhat.com/show_bug.cgi?id=1335534 The series relies on features which are not in QEMU yet, but should be hopefully close enough to be pushed in 2.9.0. In the meantime, Eduardo's work/x86-query-cpu-expansion-full branch can be used to play with them.

[libvirt] [PATCH] qemu_conf: Check for namespaces availability more wisely
by Michal Privoznik 15 Feb '17

15 Feb '17

The bare fact that mnt namespace is available is not enough for us to allow/enable qemu namespaces feature. There are other requirements: we must copy all the ACL & SELinux labels otherwise we might grant access that is administratively forbidden or vice versa. At the same time, the check for namespace prerequisites is moved from domain startup time to qemu.conf parser as it doesn't make much sense to allow users to start misconfigured libvirt just to find out they can't start a single domain.

[libvirt] [v4 0/9] Support cache tune in libvirt
by Eli Qiao 15 Feb '17

15 Feb '17

Addressed comment from v3 -> v4: Daniel & Marcelo: * Added concurrence support Addressed comment from v2 -> v3: Daniel: * Fixed coding style, passed `make check` and `make syntax-check` * Variables renaming and move from header file to c file. * For locking/mutex support, no progress. There are some discussion from mailing list, but I can not find a better way to add locking support without performance impact. I'll explain the process and please help to advice what shoud we do. VM create: 1) Get the cache left value on each bank of the host. This should be shared amount all VMs. 2) Calculate the schemata on the bank based on all created resctrl domain's schemata 3) Calculate the default schemata by scaning all domain's schemata. 4) Flush default schemata to /sys/fs/resctrl/schemata VM destroy: 1) Remove the resctrl domain of that VM 2) Recalculate default schemata 3) Flush default schemata to /sys/fs/resctrl/schemata The key point is that all VMs shares /sys/fs/resctrl/schemata, and when a VM create a resctrl domain, the schemata of that VM depends on the default schemata and all other exsited schematas. So a global mutex is reqired. Before calculate a schemata or update default schemata, libvirt should gain this global mutex. I will try to think more about how to support this gracefully in next patch set. Marcelo: * Added vcpu support for cachetune, this will allow user to define which vcpu using which cache allocation bank. <cachetune id='0' host_id=0 size='3072' unit='KiB' vcpus='0,1'/> vcpus is a cpumap, the vcpu pids will be added to tasks file * Added cdp compatible, user can specify l3 cache even host enable cdp. See patch 8. On a cdp enabled host, specify l3code/l3data by <cachetune id='0' host_id='0' type='l3' size='3072' unit='KiB'/> This will create a schemata like: L3data:0=0xff00;... L3code:0=0xff00;... * Would you please help to test if the functions work. Martin: * Xml test case, I have no time to work on this yet, would you please show me an example, would like to amend it later. This series patches are for supportting CAT featues, which also called cache tune in libvirt. First to expose cache information which could be tuned in capabilites XML. Then add new domain xml element support to add cacahe bank which will apply on this libvirt domain. This series patches add a util file `resctrl.c/h`, an interface to talk with linux kernel's system fs. There are still one TODO left: 1. Expose a new public interface to get free cache information. Some discussion about this feature support can be found from: https://www.redhat.com/archives/libvir-list/2017-January/msg00644.html Eli Qiao (9): Resctrl: Add some utils functions Resctrl: expose cache information to capabilities Resctrl: Add new xml element to support cache tune Resctrl: Add private interface to set cachebanks Qemu: Set cache banks Resctrl: enable l3code/l3data Resctrl: Make sure l3data/l3code are pairs Resctrl: Compatible mode for cdp enabled Resctrl: concurrence support docs/schemas/domaincommon.rng | 46 ++ include/libvirt/virterror.h | 1 + po/POTFILES.in | 1 + src/Makefile.am | 1 + src/conf/capabilities.c | 56 ++ src/conf/capabilities.h | 23 + src/conf/domain_conf.c | 182 +++++++ src/conf/domain_conf.h | 19 + src/libvirt_private.syms | 11 + src/nodeinfo.c | 64 +++ src/nodeinfo.h | 1 + src/qemu/qemu_capabilities.c | 8 + src/qemu/qemu_driver.c | 6 + src/qemu/qemu_process.c | 53 ++ src/util/virerror.c | 1 + src/util/virresctrl.c | 1156 +++++++++++++++++++++++++++++++++++++++++ src/util/virresctrl.h | 88 ++++ 17 files changed, 1717 insertions(+) create mode 100644 src/util/virresctrl.c create mode 100644 src/util/virresctrl.h -- 1.9.1

[libvirt] [PATCH go v2] domain.go: construct cpumaps correctly for CPU pinning verbs
by Leonid Podolny 15 Feb '17

15 Feb '17

In PinEmulator() and PinIOThread() there is an identical code that converts []bool into a bitmask. It calculates the location in the bitmask and then sets it always to 1, instead of looking at the actual bool value. --- domain.go | 16 ++++++++++------ 1 file changed, 10 insertions(+), 6 deletions(-) diff --git a/domain.go b/domain.go index 5482f1a..9ee908b 100644 --- a/domain.go +++ b/domain.go @@ -3967,10 +3967,12 @@ func (d *Domain) PinEmulator(cpumap []bool, flags DomainModificationImpact) erro maplen := (len(cpumap) + 7) / 8 ccpumaps := make([]C.uchar, maplen) for i := 0; i < len(cpumap); i++ { - byte := i / 8 - bit := i % 8 + if cpumap[i] { + byte := i / 8 + bit := i % 8 - ccpumaps[byte] |= (1 << uint(bit)) + ccpumaps[byte] |= (1 << uint(bit)) + } } ret := C.virDomainPinEmulator(d.ptr, &ccpumaps[0], C.int(maplen), C.uint(flags)) @@ -3989,10 +3991,12 @@ func (d *Domain) PinIOThread(iothreadid uint, cpumap []bool, flags DomainModific maplen := (len(cpumap) + 7) / 8 ccpumaps := make([]C.uchar, maplen) for i := 0; i < len(cpumap); i++ { - byte := i / 8 - bit := i % 8 + if cpumap[i] { + byte := i / 8 + bit := i % 8 - ccpumaps[byte] |= (1 << uint(bit)) + ccpumaps[byte] |= (1 << uint(bit)) + } } ret := C.virDomainPinIOThreadCompat(d.ptr, C.uint(iothreadid), &ccpumaps[0], C.int(maplen), C.uint(flags)) -- 2.11.0
