Use that info to add an 'architecture' property to /cluster/resources. x86 nodes won't return a value here. Signed-off-by: Dominik Csapak --- changes from v2: * use Tools get_host_arch instead of POSIX::uname() * fix adding the arch only when it's non-x86 * rename variable and api property to 'host-arch' sending only the api patch for a v3 for now just to note, the only ui adaptations for this needed are in [05/17] ui: qemu: add architecture specific defaults and helpers namely the two occurences of: PVE.data.ResourceStore.getNodeById(nodename)?.data.architecture; need a change to PVE.data.ResourceStore.getNodeById(nodename)?.data['host-arch']; PVE/API2/Cluster.pm | 9 +++++++++ PVE/Service/pvestatd.pm | 9 +++++++++ 2 files changed, 18 insertions(+) diff --git a/PVE/API2/Cluster.pm b/PVE/API2/Cluster.pm index d6003a7d..2ee988e0 100644 --- a/PVE/API2/Cluster.pm +++ b/PVE/API2/Cluster.pm @@ -484,6 +484,12 @@ __PACKAGE__->register_method({ type => "string", optional => 1, }, + 'host-arch' => { + description => "The nodes CPU architecture.
