[libvirt] [PATCH] qemu: Default hwclock source for sPAPR to RTC
by Kothapally Madhu Pavan 13 Jul '17

13 Jul '17

QEMU fails to launch a sPAPR guest with clock sources other that RTC. Internally qemu only uses RTC timer for hwclock. This patch reports the right error message instead of qemu erroring out when any other timer other than RTC is used.

[libvirt] [PATCH] Rewrite the way mockable functions are handled.
by Daniel P. Berrange 13 Jul '17

13 Jul '17

Currently any mockable functions are marked with attributes noinline, noclone and weak. This prevents the compiler from optimizing away the impl of these functions. It has an unfortunate side effect with the libtool convenience libraries, if executables directly link to them. For example virlockd, virlogd both link to libvirt_util.la When this is done, the linker does not consider weak symbols as being undefined, so it never copies them into the final executable. In this new approach, we stop annotating the headers entirely. Instead we create a weak function alias in the source. int fooImpl(void) { ..the real code.. } int foo(void) __attribute__((noinline, noclone, weak, alias("fooImpl")) If any functions in the same file call "foo", this prevents the optimizer from inlining any part of fooImpl. When linking to the libtool convenience static library, we also get all the symbols present. Finally the test suite can just directly define a 'foo' function in its source, removing the need to use LD_PRELOAD (though removal of LD_PRELOADS is left for a future patch).

[libvirt] [PATCH] cpu_x86: Properly disable unknown CPU features
by Jiri Denemark 13 Jul '17

13 Jul '17

CPU features unknown to a hypervisor will not be present in dataDisabled even though the feature won't naturally be enabled because it is unknown. Thus any features we asked for which are not in dataEnabled should be considered disabled.

[libvirt] [PATCH] qemu: shared disks with cache=directsync should be safe for migration
by Peng Hao 13 Jul '17

13 Jul '17

From: Hao Peng <peng.hao2(a)zte.com.cn> At present shared disks can be migrated with either readonly or cache=none. But cache=directsync should be safe for migration, because both cache=directsync and cache=none don't use the host page cache, and cache=direct write through qemu block layer cache.

[libvirt] Trouble with /var/lib/libvirt/qemu/save mount
by Orion Poplawski 12 Jul '17

12 Jul '17

I'm trying to get libvirt-guests ON_SHUTDOWN=suspend to work on EL7 with a separate mount point for /var/lib/libvirt/qemu/save. It appears that during host shutdown that /var/lib/libvirt/qemu/save gets unmounted before libvirt-guests gets run, resulting in the save images running out of space on my system and being mounted over on boot. I've tried adding: RequiresMountsFor=/var/lib/libvirt/qemu/save to /usr/lib/systemd/system/libvirt-guests.service, but that does not appear to help. Any other ideas? Thanks. -- Orion Poplawski Technical Manager 720-772-5637 NWRA, Boulder/CoRA Office FAX: 303-415-9702 3380 Mitchell Lane orion(a)nwra.com Boulder, CO 80301 http://www.nwra.com

If this part is really true (can libvirt developers confirm that?), then the proposed end result makes sense (not having a default for running QEMU directly, but changing default to "q35" for people using libvirt). But I don't see why we would need a new mechanism to make QEMU recommend a machine-type for libvirt, if libvirt could simply choose its own default (or maybe also refuse to pick a default, if libvirt developers decide that's the best solution). > People not using libvirt use some or all of this > and other such functionality, > and changing the default might break things for them. -- Eduardo

[libvirt] [PATCH] Avoid hidden cgroup mount points
by Juan Hernandez 12 Jul '17

12 Jul '17

Currently the scan of the /proc/mounts file used to find cgroup mount points doesn't take into account that mount points may hidden by other mount points. For, example in certain Kubernetes environments the /proc/mounts contains the following lines: cgroup /sys/fs/cgroup/net_prio,net_cls cgroup ... tmpfs /sys/fs/cgroup tmpfs ... cgroup /sys/fs/cgroup/net_cls,net_prio cgroup ... In this particular environment the first mount point is hidden by the second one. The correct mount point is the third one, but libvirt will never process it because it only checks the first mount point for each controller (net_cls in this case). So libvirt will try to use the first mount point, which doesn't actually exist, and the complete detection process will fail. To avoid that issue this patch changes the virCgroupDetectMountsFromFile function so that when there are duplicates it takes the information from the last line in /proc/mounts. This requires removing the previous explicit condition to skip duplicates, and adding code to free the memory used by the processing of duplicated lines.

[libvirt] [PATCH] qemu: Provide non-linux stub for qemuDomainAttachDeviceMknodRecursive
by Michal Privoznik 11 Jul '17

11 Jul '17

The way we create devices under /dev is highly linux specific. For instance we do mknod(), mount(), umount(), etc. Some platforms are even missing some of these functions. Then again, as declared in qemuDomainNamespaceAvailable(): namespaces are linux only. Therefore, to avoid obfuscating the code by trying to make it compile on weird platforms, just provide a non-linux stub for qemuDomainAttachDeviceMknodRecursive(). At the same time, qemuDomainAttachDeviceMknodHelper() which actually calls the non-existent functions is moved under ifdef __linux__ block since its only caller is in that block too.

[libvirt] [PATCH] internal: don't use weak symbols for Win32 platform
by Daniel P. Berrange 11 Jul '17

11 Jul '17

The Win32 platform will fail to link if you use weak symbols because it is incompatible with exporting symbols in a DLL: Cannot export virRandomGenerateWWN: symbol wrong type (2 vs 3) We only need weak symbols for our test suite to do LD_PRELOAD and this doesn't work on Win32, so we can just drop the hack for Win32 Signed-off-by: Daniel P.

[libvirt] [PATCH] qemu: handle missing bind host/service on chardev hotplug

On domain startup, bind host or bind service can be omitted and we will format a working command line.

[libvirt] [PATCH] qemu: Fix qemuDomainGetBlockInfo allocation value setting
by John Ferlan 11 Jul '17

11 Jul '17

https://bugzilla.redhat.com/show_bug.cgi?id=1467826 Commit id 'b9b1aa639' was supposed to add logic to set the allocation for sparse files when wr_highest_offset was zero; however, an unconditional setting was done just prior. For block devices, this means allocation is always returning 0 since 'actual-size' will be zero. Remove the unconditional setting and add the note about it being possible to still be zero for block devices. As soon as the guest starts writing to the volume, the allocation value will then be obtainable from qemu via the wr_highest_offset.

[libvirt] How to make gic_version=3 as defailt to qemu on arm64
by Vishnu Pajjuri 11 Jul '17

11 Jul '17

Hi I'm running Openstack which is installed by using devstack. But it is not launching VMs. >From command line with gic_version=3 option it is running. But openstack glance doesn't have any privilege to specify gic version. On my ARM64 board gicv2 is not supported, so i want to make gicv3 as default one to pass to qemu. Kindly suggest any specific version of vibvirt or patch such that libvirt should pass gicv3 as default one. Thanks in Advance -Vishnu.
