Subject: [PATCH] DomainCpu: check CPU model name only if model exists
For CPU modes other then "custom" there is no model so we should not
check the suffix of model name.

Subject: [PATCH] DomainCpu: fix detection of CPU security features
VM configured with mode="host-model" will have the CPU definition
expanded once the VM is started. Libvirt will try to use the closest
CPU model with some features enabled/disabled.
The issue is that there are some models that include spec-ctrl or ibpb
features and they will not appear in the explicit list of features and
virt-manager will not correctly detect if all security features are
enabled or not. As a workaround we can check the suffix of CPU model to
figure out which security features are enabled by the model itself.

Subject: [PATCH] cli: Fix pool=default when path belongs to another pool (bz
1692489)
From: Cole Robinson <crobinso@redhat.com>
Using 'virt-install --disk size=X' implicitly uses pool=default. If
a pool named 'default' exists we use that; if not, and a pool using
the default path exists under a different name, we attempt to use
that as well, and if that doesn't exist, we create pool=default
The second case is broken, so if there's no pool=default and eg.
pool=FOO points to /var/lib/libvirt/images, we still attempt to
look up pool=default which understandably fails

The 'secure' option is processed after the model is already set.
CPU security options are resolved while setting CPU model so we need
to know the 'secure' option value before we set the CPU model.

what security features are available on the host.

Subject: [PATCH] domcapabilities: introduce get_cpu_security_features
Get all CPU security features that we should enable for guests.
In order to do that we need to get CPU definition from domain
capabilities and modify the XML so it is in required format for
libvirt CPU baseline APIs. We will prefer the baselineHypervisorCPU
API because that considers what QEMU actually supports and we will
fallback to baselineCPU API if the better one is not supported by
libvirt.
This way we can figure out which of the security features are actually
available on that specific host for that specific QEMU binary.

Subject: [PATCH] domcapabilities: remove recommended CPU features from
security features
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
These features are only recommended to be enabled since they improve
performance of the VMs if security features are enabled.
pcid is a very useful perf feature, but missing in some silicon
so not portable.
pdpe1gb lets the guest use 1 GB pages which is good for perf
but again not all silicon can do it.
amd-ssbd is a security feature which fixes the same SSBD flaws as the
virt-ssbd feature does. virt-ssbd is usable across all CPU models
affected by SSBD, while amd-ssbd is only available in very new silicon.
So virt-ssbd is the bette rchoice.
amd-no-ssb just indicates that the CPU is not affected by SSBD, so not
critical to expose. I expect a future named CPU model will include that
where appropriate.

Message-Id: <c05e60de1acb174bb40257d3481267e35dc62960@dist-git>

Subject: [PATCH] virt-manager: add new checkbox to control CPU security
features
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
By default we copy CPU security features to the guest if specific CPU
model is selected. However, this may break migration and will affect
performance of the guest. This adds an option to disable this default
behavior.
The checkbox is clickable only on x86 and only on host where we can
detect any CPU security features, otherwise a tooltip is set to notify
users that there is nothing to copy.
