Package: libvirt-daemon Version: 1.2.9-6 Severity: important Dear Maintainer,
The intel-microcode 3.20140913.1 update disables TSX-NI (transactional memory instructions). When a server running libvirt is rebooted with this update, libvirt no longer considers the machine to have a Haswell CPU: dietrich ~ # virsh capabilities | grep -A1 '<arch>x86_64' <arch>x86_64</arch> <model>SandyBridge</model> This causes a problem as any VMs that require a Haswell CPU, which would have worked previously, now fail to start altogether. Commenting out the two cpuinfo flags relevant to TSX-NI from /usr/share/libvirt/cpu_map.xml fixes this for me: --- cpu_map.xml.orig 2014-11-24 11:47:47.000000000 +0000 +++ cpu_map.xml 2014-12-15 12:33:21.485278484 +0000 @@ -507,13 +507,13 @@ <feature name='movbe'/> <feature name='fsgsbase'/> <feature name='bmi1'/> - <feature name='hle'/> + <!--feature name='hle'/--> <feature name='avx2'/> <feature name='smep'/> <feature name='bmi2'/> <feature name='erms'/> <feature name='invpcid'/> - <feature name='rtm'/> + <!--feature name='rtm'/--> </model> <model name='Broadwell'> HTH, Chris -- System Information: Debian Release: 8.0 APT prefers testing APT policy: (990, 'testing'), (500, 'testing-updates'), (500, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 3.16.0-4-amd64 (SMP w/8 CPU cores) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages libvirt-daemon depends on: ii libapparmor1 2.9.0-2 ii libaudit1 1:2.4-1+b1 ii libavahi-client3 0.6.31-4+b2 ii libavahi-common3 0.6.31-4+b2 ii libblkid1 2.25.2-3 ii libc6 2.19-13 ii libcap-ng0 0.7.4-2 ii libdbus-1-3 1.8.12-1 ii libdevmapper1.02.1 2:1.02.90-2 ii libfuse2 2.9.3-15+b1 ii libgnutls-deb0-28 3.3.8-5 ii libnetcf1 1:0.2.3-4.1 ii libnl-3-200 3.2.24-2 ii libnl-route-3-200 3.2.24-2 ii libnuma1 2.0.10-1 ii libparted2 3.2-6 ii libpcap0.8 1.6.2-2 ii libpciaccess0 0.13.2-3+b1 ii librados2 0.80.7-1 ii librbd1 0.80.7-1 ii libsasl2-2 2.1.26.dfsg1-12 ii libselinux1 2.3-2 ii libssh2-1 1.4.3-4 ii libsystemd0 215-7 ii libudev1 215-7 ii libvirt0 1.2.9-6 ii libxen-4.4 4.4.1-5 ii libxenstore3.0 4.4.1-5 ii libxml2 2.9.1+dfsg1-4 ii libyajl2 2.1.0-2 Versions of packages libvirt-daemon recommends: ii libxml2-utils 2.9.1+dfsg1-4 ii netcat-openbsd 1.105-7 pn qemu-kvm | qemu <none> Versions of packages libvirt-daemon suggests: ii libvirt-daemon-system 1.2.9-6 -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
