[libvirt] [PATCHv2 00/16] Introduce hvf domain type for Hypevisor.framework
by Roman Bolshakov
Hypervisor.framework provides a lightweight interface to run a virtual
cpu on macOS without the need to install third-party kernel
extensions (KEXTs).
It's supported since macOS 10.10 on machines with Intel VT-x feature
set that includes Extended Page Tables (EPT) and Unrestricted Mode.
QEMU supports Hypervisor.framework since 2.12.
The patch series adds "hvf" domain that uses Hypevisor.framework.
v1: https://www.redhat.com/archives/libvir-list/2018-October/msg01090.html
Changes since v1:
- [x] Fixed unconditional addition of KVM CPU models into capabilities cache.
That fixed a "make check" issue in qemucapabilitiestest on Linux.
- [x] Fixed missing brace in virQEMUCapsFormatCPUModels in PATCH 6
- [x] Squashed patch 12 into the first patch (second one in the patch series)
- [x] Added hvf domain definition to docs/formatdomain.html.in into the first
patch (second in the patch series)
- [x] Removed redundant argument in virQEMUCapsProbeHVF (patch 3)
- [x] Added separate virQEMUCapsProbeHVF for non-apple platforms (patch 3)
- [x] Added macOS support page
- [x] Marked HVF support for all working domain elements
I wasn't able to resolve the issues below, but I think they should go
into separate patches/patch series:
- [ ] To make qemucapabilitiestests work regardless of OS, accelerator probing
should be done via QMP command.
So, there's a need to add a new generic
command to QEMU "query-accelerator accel=NAME"
- [ ] VIRT_TEST_PRELOAD doesn't work on macOS. There are a few
reasons:
* DYLD_INSERT_LIBRARIES should be used instead of LD_PRELOAD
*
-module flag shouldn't be added to LDFLAGS in tests/Makefile.am.
The flag instructs libtool to creates bundles (MH_BUNDLE) instead of
dynamic libraries (MH_DYLIB) and unlike dylibs they cannot be preloaded.
* Either symbol interposing or flat namespaces should be used to perform
overrides of the calls to the mocks.
I've tried both but neither worked for me, need to make a minimal
example.
I haven't completed the investigation as it looks like a separate work item.
- [ ] Can't retrieve qemucapsprobe replies for macOS because qemucapsprobemock
is not getting injected because of the issue with VIRT_TEST_PRELOAD
- [ ] Can't add to tests/qemuxml2argvtest.c to illustrate the hvf example
because qemucapsprobe doesn't work yet.

[libvirt] [PATCH v3] qemu: Add check for whether KVM nesting is enabled
by John Ferlan
Support for nested KVM is handled via a kernel module configuration
parameters values for kvm_intel, kvm_amd, kvm_hv (PPC), or kvm (s390).
While it's possible to fetch the kmod config values via virKModConfig,
unfortunately that is the static value and we need to get the
current/dynamic value from the kernel file system.
So this patch adds a new API virHostKVMSupportsNesting that will
search the 3 kernel modules to get the nesting value and check if
it is 'Y' (or 'y' just in case) or '1' to return a true/false whether
the KVM kernel supports nesting.
We need to do this in order to handle cases where adjustments to
the value are made after libvirtd is started to force a refetch of
the latest QEMU capabilities since the correct CPU settings need
to be made for a guest to add the "vmx=on" to/for the guest config.

Changes from code review...
- Rename variables/API's to KVMSupportsNested
- Movement of logic to check/set the 'nested' to inside locations that
ensure KVM was enabled (via capability).
- Change of logic to not use virKModConfig and instead look at the
running kernel value for /sys/module/*/parameters/nested where *
is kvm_intel, kvm_amd, kvm_hv, or kvm

[libvirt] [PATCH v3 0/2] lxc: Fix a bug related to IPv{4, 6} gateway persistent setting.
by Julio Faracco
This serie fixes a bug related to IPv{4,6} gateway settings when it is
defined and used with multiple network definitions. Basically, this data
is being carried on to the next network settings because the pointer is
not being cleaned up/initialized properly. The idea behind the fix was
create a new way to initialize the data without knowing the structure
attributes. The old way has a high probability to cause new bugs.
This serie add a new test case to cover this scenario too. It will be so
important to network index implemented on LXC 3.X.
v1-v2: Fixing tabs inside the code.

[libvirt] [PATCH] qemu: Don't use -mem-prealloc among with .prealloc=yes
by Michal Privoznik
https://bugzilla.redhat.com/show_bug.cgi?id=1624223
There are two ways to request memory preallocation on cmd line:
-mem-prealloc and .prealloc attribute to memory-backend-file.
However, as it turns out it's not safe to use both at the same
time. Prefer -mem-prealloc as it is more backward compatible
compared to switching to "-numa node,memdev= + -object
memory-backend-file".

[libvirt] [PATCH] qemu: Qemu process unexpectedly killed in repeated reboot
by Wang King
The issue occurs when I make repeated calls to virDomainReboot with
VIR_DOMAIN_REBOOT_DEFAULT flag. In the first call to reboot domain,
the qemu driver chose ACPI path, and set priv->fakeReboot to true.
Then in a second call, qemu driver chose agent to reboot which set
fakeReboot to false. But because the guest already responded to ACPI
shut down, libvirtd daemon will process a SHUTDOWN event in
qemuProcessShutdownOrReboot and checks priv->fakeReboot. Since the
fakeReboot flag is now false, qemu process is unexpectedly killed.
I have no idea how to fix it.
