Wed, 09 Oct 2019 12:03:43 +0000 (UTC) Content-Type: text/plain; charset="utf-8" Since QEMU v4.0.0, the host's model is no longer automatically exposed to the guest via /proc/device-tree/host-model. There is now a machine option 'host-model' that allows an arbitrary string to be used as the host model [1]. This patch adds support for exposing the real host model string from /proc/cpuinfo (also found on /proc/device-tree/model) to the guest via -machine pseries,host-model=3D by setting in the domain XML file: The functionality is disabled by default to avoid leaking host information to the guest. 1 - https://git.qemu.org/?p=3Dqemu.git;a=3Dcommitdiff;h=3D0a794529bd11 Signed-off-by: Fabiano Rosas --- docs/formatdomain.html.in | 9 ++++++ docs/schemas/domaincommon.rng | 5 ++++ src/conf/domain_conf.c | 4 +++ src/conf/domain_conf.h | 1 + src/qemu/qemu_command.c | 25 ++++++++++++++-- src/qemu/qemu_domain.c | 1 + tests/qemuxml2argvdata/pseries-features.args | 3 +- tests/qemuxml2argvdata/pseries-features.xml | 1 + tests/qemuxml2argvtest.c | 30 ++++++++++++++++++- tests/qemuxml2xmloutdata/pseries-features.xml | 1 + 10 files changed, 75 insertions(+), 5 deletions(-) diff --git a/docs/formatdomain.html.in b/docs/formatdomain.html.in index 647f96f651..b613f61f23 100644 --- a/docs/formatdomain.html.in +++ b/docs/formatdomain.html.in @@ -2357,6 +2357,15 @@ will not be ignored.
