+ <h1 >macOS support</h1>
+
+ <ul id="toc"></ul>
+
+ <p>
+ Libvirt works both as client and server (for <a href="drvqemu.html">
+ "qemu" domain</a>) on macOS High Sierra (10.13) and macOS Mojave (10.14)
+ since 4.7.0. Other macOS variants likely work but we neither tested nor
+ received reports for them.
+ </p>
+
+ <p>
+ <a href="drvqemu.html">"hvf" domain type</a> adds support of <a
+ href="https://developer.apple.com/documentation/hypervisor">
+ Hypervisor.framework</a> since 4.10.0. To use "hvf" domain, QEMU must
+ be at least 2.12 and macOS must be no less than Yosemite (10.10). "hvf"
+ domain type is similar to "kvm" but it has less features.
+ </p>
+
+ <p>
+ Hypervisor.framework is available on your machine if the sysctl command
+ returns 1:
+
+ <pre>sysctl -n kern.hv_support</pre>
+ </p>
+
+ <h2><a id="installation">Installation</a></h2>
+
+ <p>
+ libvirt client (virsh), server (libvirtd) and development headers can be
+ installed from <a href="https://brew.sh">homebrew</a>:
+
+ <pre>brew install libvirt</pre>
+
+ <a href="http://virt-manager.org">virt-manager and virt-viewer</a> can be
+ installed from source via <a
+ href="https://github.com/jeffreywildman/homebrew-virt-manager">
+ Jeffrey Wildman's tap</a>:
+
+ <pre>brew tap jeffreywildman/homebrew-virt-manager
+brew install virt-manager virt-viewer</pre>
+ </p>
+
+ <h2><a id='local-libvirtd'>Running libvirtd locally</a></h2>
+
+ <p>
+ The server can be started manually:
+ <pre>libvirtd</pre>
+ or on system boot:
+ <pre>brew services start libvirt</pre>
+ </p>
+ <p>
+ Once started, you can use virsh to work with libvirtd:
+ <pre>virsh define domain.xml
+virsh start domain
+virsh shutdown domain</pre>
+
+ For more details on virsh, please see <a href="virshcmdref.html">virsh
+ command reference</a> or built-in help:
+ <pre>virsh help</pre>
+ </p>
+
+ <p>
+ Domain XML examples can be found on <a href="drvqemu.html#xmlconfig">QEMU
+ driver page</a>. Full reference is available on <a
+ href="formatdomain.html">domain XML format page</a>.
+ </p>
+
+ <p>
+ You can use virt-manager to connect to libvirtd (connection URI must be
+ specified on the first connection, then it'll be possible to omit it):
+ <pre>virt-manager -c qemu:///session</pre>
+ or, if you only need an access to the virtual display of a VM you can use
+ virt-viewer:
+ <pre>virt-viewer -c qemu:///session</pre>
+ </p>
+
+ <h2><a id="external-hypervisors">Working with external hypervisors</a></h2>
+ <p>
+ Details on the example domain XML files, capabilities and connection
+ string syntax used for connecting to external hypervisors can be found
+ online on <a href="drivers.html">hypervisor specific driver
+ pages</a>.
+ </p>
+
+ <h2><a id="tlscerts">TLS Certificates</a></h2>
+
+ <p>
+ TLS certificates must be placed in the correct locations, before you will
+ be able to connect to QEMU servers over TLS.
+ </p>
+
+ <p>
+ Information on generating TLS certificates can be found here:
+ </p>
+
+ <a href="http://wiki.libvirt.org/page/TLSSetup">http://wiki.libvirt.org/page/TLSSetup</a>
+
+ <p>
+ The Certificate Authority (CA) certificate file must be placed in:
+ </p>
+
+ <ul>
+ <li>~/.cache/libvirt/pki/CA/cacert.pem</li>
+ </ul>
+
+ <p>
+ The Client certificate file must be placed in:
+ </p>
+
+ <ul>
+ <li>~/.cache/libvirt/pki/libvirt/clientcert.pem</li>
+ </ul>
+
+ <p>
+ The Client key file must be placed in:
+ </p>
+
+ <ul>
+ <li>~/.cache/libvirt/pki/libvirt/private/clientkey.pem</li>
+ </ul>
+
+ <h2><a id="known-issues">Known issues</a></h2>
+ <p>
+ This is a list of issues that can be easily fixed and provide
+ substantial improvement of user experience:
+ </p>
+ <ul>
+ <li>
+ virt-install doesn't work unless disks are created upfront. The reason
+ is because VIR_STORAGE_VOL_CREATE_PREALLOC_METADATA sets
+ preallocate=falloc which is not supported by qemu-img on macOS.
+ </li>
+ <li>
+ "hvf" is not default domain type when virt-install connects to the
+ local libvirtd on macOS
+ </li>
+ <li>
+ QXL VGA device and SPICE display cannot be used unless QEMU is compiled
+ with SPICE server. The changes to build and run SPICE server on macOS
+ haven't been sent to upstream yet.
+ </li>
+ <li>
+ "make check" reports many failing tests on macOS. Some of the tests
+ need to be adopted to run both on Linux and macOS.
+ </li>
+ <li>
+ "make syntax-check" needs be fixed too, it depends on GNU version of
+ grep but uses system (BSD) grep.
+ </li>
+ <li>
+ QEMU from homebrew is compiled without USB redirection support.
+ </li>
+ <li>
+ CPU usage is not gathered for VMs and therefore cannot be dispalyed in
+ virt-manager.
+ </li>
+ <li>
+ libvirtd logs are noisy because some features are missing.
+ </li>
+ </ul>
+
+ <h2><a id="missing-features">Missing features</a></h2>
+ <p>
+ "hvf" is a new domain type and can't be compared to "kvm" feature-wise.
+ "kvm" domain relies on QEMU backend devices implemented in Linux kernel
+ such as para-virtualized vhost devices and PCI-passthrough with vfio.
+
+ Nonetheless, some of the features available in "kvm" domain can be
+ implemented in userspace for "hvf" domain.
+ </p>
+ <ul>
+ <li>
+ Instruction emulation in "hvf" accelerator is not mature. The bugs are
+ tracked on <a
+ href="https://bugs.launchpad.net/qemu/+bugs?field.tag=hvf">QEMU bug
+ tracker</a>.
+ </li>
+ <li>
+ Power Management notifications are not implemented, therefore guests
+ cannot respond to <a
+ href="https://developer.apple.com/library/archive/qa/qa1340/_index.html">
+ sleep events on the host</a>.
+ </li>
+ <li>
+ CPU pinning doesn't work but macOS provides <a
+ href="https://developer.apple.com/library/archive/releasenotes/Performance/RN-AffinityAPI/">
+ Thread Affinity API</a> that can be used to implement it.
+ </li>
+ <li>
+ Network management is not available but macOS has an API that is used
+ by ifconfig to create bridge and tap devices. So, it should be possible
+ to implement network management and bridged networking.
+ </li>
+ <li>
+ Filesystem pass-through is not available.
+ </li>
+ <li>
+ PCI/SCSI/USB pass-through is not available.
+ </li>
+ </ul>
