[PATCH 1/7] conf: Add NFS disk protocol
by Ryan Gahagan
Per Issue 90, Libvirt does not support attaching an NFS disk even though
QEMU has added support for it. This series of patches seeks to implement
this support in Libvirt and begins by adding in flags for an NFS disk.

[PATCH RFC v4 00/15] Add riscv kvm accel support
by Yifei Jiang
This series adds both riscv32 and riscv64 kvm support, and implements
migration based on riscv. It is based on temporarily unaccepted kvm:
https://github.com/kvm-riscv/linux (lastest version v15).
This series depends on above pending changes which haven't yet been
accepted, so this QEMU patch series is treated as RFC patches until
that dependency has been dealt with.
Compared to RFC v3, the time scaling is supported in this series. The
new feature also requires the following patches:
[1] Bugfix in kvm v15
https://lkml.org/lkml/2020/11/30/245
[2] kvm patches:
[PATCH RFC 0/3] Implement guest time scaling in RISC-V KVM
Several steps to use this:
1. Build emulation
$ ./configure --target-list=riscv64-softmmu
$ make -j$(nproc)
2. Build kernel
https://github.com/kvm-riscv/linux
3. Build QEMU VM
Cross built in riscv toolchain.
$ PKG_CONFIG_LIBDIR=<toolchain pkgconfig path>
$ export PKG_CONFIG_SYSROOT_DIR=<toolchain sysroot path>
$ ./configure --target-list=riscv64-softmmu --enable-kvm \
--cross-prefix=riscv64-linux-gnu- --disable-libiscsi --disable-glusterfs \
--disable-libusb --disable-usb-redir --audio-drv-list= --disable-opengl \
--disable-libxml2
$ make -j$(nproc)
4. Start emulation
$ ./qemu-system-riscv64 -M virt -m 4096M -cpu rv64,x-h=true -nographic \
-name guest=riscv-hyp,debug-threads=on \
-smp 4 \
-bios ./fw_jump.bin \
-kernel ./Image \
-drive file=./hyp.img,format=raw,id=hd0 \
-device virtio-blk-device,drive=hd0 \
-append "root=/dev/vda rw console=ttyS0 earlycon=sbi"
5. Start kvm-acceled QEMU VM in emulation
$ ./qemu-system-riscv64 -M virt,accel=kvm -m 1024M -cpu host -nographic \
-name guest=riscv-guset \
-smp 2 \
-bios none \
-kernel ./Image \
-drive file=./guest.img,format=raw,id=hd0 \
-device virtio-blk-device,drive=hd0 \
-append "root=/dev/vda rw console=ttyS0 earlycon=sbi"
Changes since RFC v3
- Rebase on QEMU v5.2.0-rc2 and kvm-riscv linux v15.
- Add time scaling support(New patches 13, 14 and 15).
- Fix the bug that guest vm can't reboot.
Changes since RFC v2
- Fix checkpatch error at target/riscv/sbi_ecall_interface.h.
- Add riscv migration support.
Changes since RFC v1
- Add separate SBI ecall interface header.
- Add riscv32 kvm accel support.
Yifei Jiang (15):
linux-header: Update linux/kvm.h
target/riscv: Add target/riscv/kvm.c to place the public kvm interface
target/riscv: Implement function kvm_arch_init_vcpu
target/riscv: Implement kvm_arch_get_registers

[PATCH 00/10] Fix NSS plugin and net-dhcp-get-leases wrt to infinite leases
by Michal Privoznik
Some things are broken when using leases that don't expire. We don't
store "expiry-time" in corresponding $brname.status file which sets off
a spiral and we get errors from other places which expect it to be there
always. These patches make sure that the attribute is always there. I've
also implemented another approach, which puts "expiry-time" into the
file only if not infinite and fixed the other places which expect it:
https://gitlab.com/MichalPrivoznik/libvirt/-/commits/leases_docs/
but I like this version more.

[libvirt PATCH v2 0/5] vmx: Don't error out on missing filename for cdrom
by Martin Kletzander
This is perfectly valid in VMWare and the VM just boots with an empty drive. We
used to just skip the whole drive before, but since we changed how we parse
empty cdrom drives this now results in an error and the user not being able to
even dump the XML. Instead of erroring out, just keep the drive empty.
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1903953

- Do not report and reset an error, but handle it more nicely.

Release of libvirt-6.5.0
by Daniel Veillard
Half a day late, but I pushed the 6.5.0 release out, it is as usual
available as a signed tarball and source rpms from the server:
https://libvirt.org/sources/
I also tagged and pushed the 6.5.0 python bindings that one can find at
https://libvirt.org/sources/python/
This release includes a number of new features and some improvement,
as well as a crash which had made its way in 6.4.0.
It will also be my last release of libvirt after close to 15 years,
so expect new releases to be signed by Jiri Denemark from now on.
* New Features:
- Allow firmware blobs configuration
QEMU offers a way to tweak how firmware configures itself
and/or provide new configuration blobs. New ``<sysinfo/>``
type is introduced that will hold these new blobs.
It's possible to either specify new value as a string or
provide a filename which contents then serve as the value.
- nodedev: Add ability to create mediated devices
Mediated devices can now be created with ``virNodeDeviceCreateXML()``. This
functionality requires the ``mdevctl`` utility to be installed. The XML
schema for node devices was expanded to support attributes for mediated
devices.
- QEMU: add TPM Proxy device support
libvirt can now create guests using a new device type called
"TPM Proxy". The TPM Proxy connects to a TPM Resource Manager
present in the host, enabling the guest to run in secure virtual
machine mode with the help of an Ultravisor. Adding a TPM Proxy to
a pSeries guest brings no security benefits unless the guest is
running on a PPC64 host that has Ultravisor and TPM Resource Manager
support. Only one TPM Proxy is allowed per guest. A guest using
a TPM Proxy device can instantiate another TPM device at the same
time. This device is supported only for pSeries guests via the new
'spapr-tpm-proxy' model of the TPM 'passthrough' backend.
- virhook: Support hooks placed in several files
Running all scripts from directory /etc/libvirt/hooks/<driver>.d in
alphabetical order. Hook script in old place will be executed
as first for backward compatibility.
- qemu: Add support for migratable host-passthrough CPU
QEMU 2.12 made it possible for guests to use a migration-friendly
version of the host-passthrough CPU. This feature is now exposed by
libvirt.
* Improvements:
- network: Support NAT with IPv6
It's now possible to use ``<nat ipv6="yes"/>`` in a libvirt network.
- qemu: Auto-fill NUMA information for incomplete topologies
If the NUMA topology is not fully described in the guest XML, libvirt
will complete it by putting all unspecified CPUs in the first NUMA node.
This is only done in the QEMU binary itself supports disjointed CPU
ranges for NUMA nodes.
- qemu: Assign hostdev-backed interfaces to PCIe slots
All SR-IOV capable devices are PCIe, so when their VFs are assigned to
guests they should end up in PCIe slots rather than conventional PCI ones.
* Bug fixes:
- qemu: fixed crash in ``qemuDomainBlockCommit``
This release fixes a regression which was introduced in libvirt v6.4.0
where libvirtd always crashes when a block commit of a disk is requested.
- qemu: fixed zPCI address auto generation on s390
Removes the correlation between the zPCI address attributes uid and fid.
Fixes the validation and autogeneration of zPCI address attributes.
- qemu: Skip pre-creation of NVMe disks during migration
libvirt has no way to create NVMe devices on the target host, so it now
just makes sure they exist and let the migration proceed in that case.
Thanks everybody for the help on putting this release out, and
the gazillion ones before :-)
Enjoy and stay safe !
Daniel
