[libvirt PATCH 0/7] Define and enable Snowridge CPU model
by Tim Wiederhake 08 Jan '21

08 Jan '21

This series adds and enables the Snowridge CPU model. Note that qemu currently uses the same model ID for Icelake-Server [1] and Snowridge [2]. The correct ID for Icelake is 106 [3], a mistake that has been fixed in libvirt already [4], but is still missing in qemu [5].

[libvirt PATCH 00/17] split and cleanup virStorageSource code
by Pavel Hrdina 07 Jan '21

The series is a prerequisite for implementing vhost-user-blk-pci. I wanted to use already existing code to parse and format virDomainChrSourceDefPtr as the vhostuser <disk> source similarly like we do for <interface> but it was not possible because the virStorageSource definition was living in util directory where we don't allow including anything from conf directory.
