[libvirt PATCH] qemu: Ignore missing vm.unprivileged_userfaultfd sysctl
by Jiri Denemark 09 Feb '22

09 Feb '22

Older kernels did not support this sysctl, but did not restrict userfaultfd in any way so everything worked as if vm.unprivileged_userfaultfd was set to 1. Thus we can safely ignore errors when setting the value.

[PATCH] libxl: Release auto-allocated spice ports
by Jim Fehlig 08 Feb '22

08 Feb '22

While VNC ports auto-allocated by the libxl driver are released in libxlDomainCleanup, spice ports are overlooked. Rework the existing logic to release any auto-allocated graphics ports, not just the VNC port of the first graphics device.

[libvirt][PATCH v10 0/5] Support query and use SGX
by Haibin Huang 08 Feb '22

08 Feb '22

This patch series provides support for enabling Intel's Software Guard Extensions (SGX) feature in guest VM. Giving the SGX support in QEMU had been merged. Intel SGX is a set of instructions that increases the security of application code and data, giving them more protection from disclosure or modification. Developers can partition sensitive information into enclaves, which are areas of execution in memory with more security protection. It depends on QEMU fixing[1], which will move cpu QOM object from /machine/unattached/device[nn] to /machine/cpu[nn]. It requires libvirt to change the default cpu QOM object location once QEMU patch gets accepted, but it is out of this SGX patch scope. The typical flow looks below at very high level: 1. Calls virConnectGetDomainCapabilities API to domain capabilities that includes the following SGX information. <feature> ... <sgx supported='yes'> <epc_size unit='KiB'>N</epc_size> </sgx> ... </feature> 2. User requests to start a guest calling virCreateXML() with SGX requirement. It does not support NUMA yet, since latest QEMU 6.2 release does not support NUMA. It should contain <devices> ... <memory model='sgx-epc'> <target> <size unit='KiB'>N</size> </target> </memory> ... </devices> [1]

[PATCH] libxl: Set auto-allocated graphics ports to used on reconnect
by Jim Fehlig 08 Feb '22

08 Feb '22

The libxl driver reconnects to all running VMs when libvirtd is restarted, but it failed to mark auto-allocated graphics ports as set in the port allocator. If many VMs are running that use port auto-allocation and libvirtd is restarted, the port allocator is likely to hand out a port already in use when a new VM is created that uses auto-allocation. VM creation will fail due to the port clash. When reconnecting to running VMs after a libvirtd restart, let the port allocator know about previously allocated ports.

[PATCH 0/3] Mdev test cleanup, completion and parent addr exposure
by Boris Fiuczynski 08 Feb '22

08 Feb '22

Clean up the testing json. Add a test for vfio-ccw mdev. Expose the parent address in the XML when dumping a mdev nodedev as the address is now part of the mdev nodedev name and users should not parse and manipulate the mdev nodedev name to retrieve it.
