by Pavel Hrdina 21 Jun '18

21 Jun '18

I'm happy to announce the release of libvirt-dbus 1.1.0. libvirt-dbus wraps libvirt API to provide high-level object-oriented API better suited for dbus-based applications. You can download it here: https://libvirt.org/sources/dbus/libvirt-dbus-1.1.0.tar.gz * New features - Support for all relevant nwfilter APIs up to libvirt 3.0.0 - Support for all relevant storage volume APIs up to libvirt 3.0.0 - Support for all relevant node device APIs up to libvirt 3.0.0 * Bug fixes - Don't report error for GetAll on properties if some property is not accessible Thanks everybody who contributed!

[libvirt] [PATCH] cpu: add 'amd-ssbd' and 'amd-no-ssb' CPU features (CVE-2018-3639)
by Daniel P. Berrangé 21 Jun '18

21 Jun '18

AMD x86 CPUs have two separate ways to mitigate the Speculative Store Bypass hardware flaw. In current processors only non-architectural MSRs are available, and so hypervisors must expose a virtualized MSR and CPU flag "virt-ssbd" (CPUID Function 8000_0008, EBX[25]=1). In future processors AMD will provide an architectural MSR, indicated by existance of the CPUID Function 8000_0008, EBX[24]=1, to which QEMU has given the name "amd-ssbd". The "amd-ssbd" flag should be used in preference to "virt-ssbd", if it is available, since it provides improved performance. For virtual machine configuration, both should be exposed when available, to allow for maximal guest OS compatibility as not all guests yet support both. If future processes are not vulnerable to the flaw, this will be indicated by the existance of CPUID Function 8000_0008, EBX[26]=1, to which QEMU has given the name "amd-no-ssb". See also 124441_AMD64_SpeculativeStoreBypassDisable_Whitepaper_final.pdf from: https://bugzilla.kernel.org/show_bug.cgi?id=199889 Note that neither amd-ssbd or amd-no-ssb will be reported by the kernel in /proc/cpuinfo. It knows about these CPUID bits and does the right thing, but doesn't report their existance as distinct flags in /proc/cpuinfo. Signed-off-by: Daniel P.

[libvirt] [PATCH] schema: allow a <rule> element with no subelements in a nwfilter
by Laine Stump 21 Jun '18

21 Jun '18

This is a regression in behavior caused by commit 37359814. It was intended to limit the schema to allow only a single subelement of <rule>, but it is also acceptable for <rule> to have no subelement at all. To prevent the same error from reoccurring in the future, the examples/xml/nwfilter directory was added to the list of nwfilter schema test directories.

That said, can we deprecate this feature in libvirt, encourage applications to always specify an explicit machine-type, thus making it possible to deprecate the i440fx machine-types one day? -- Eduardo
