Implementations

impl PostinstallKernelChecks

pub fn new(host_executor: HostNamespaceExecutor) -> Self

pub async fn run_all(&self) -> CheckGroupResult

Run all the checkers asynchronously, then join and collect the results.

pub async fn version_is_good(&self) -> CheckResult

Checks that the running kernel is at least version 5.15.0.

Manual equivalent:

uname -r  # must be >= 5.15.0

pub async fn has_modules(&self) -> CheckResult

Checks that all required Xen and networking modules are available as built-in, currently loaded, or loadable (present in modules.dep) for the running kernel.

Manual equivalent:

KV=$(uname -r)
for mod in nf_tables xen_evtchn xen-privcmd xen-netback xen-pciback xen-blkback xen-gntdev xen-gntalloc; do
  grep -q "$mod" /lib/modules/$KV/modules.builtin \
    || grep -q "^${mod} " /proc/modules \
    || grep -q "$mod" /lib/modules/$KV/modules.dep \
    && echo "$mod: OK" || echo "$mod: MISSING"
done
