ansible - 如何忽略ansible中的警告

Question

我在编写剧本时一直试图忽略警告，场景是我执行此 virt-host-validate qemu它会发出一个警告，如下所示。

root@n0:~/playbook_promenade# virt-host-validate 
QEMU: Checking for hardware virtualization : PASS
QEMU: Checking if device /dev/kvm exists :PASS
QEMU: Checking if device /dev/kvm is accessible : PASS
QEMU: Checking if device /dev/vhost-net exists : PASS
QEMU: Checking if device /dev/net/tun exists : PASS
QEMU: Checking for cgroup 'memory' controller support : PASS
QEMU: Checking for cgroup 'memory' controller mount-point : PASS
QEMU: Checking for cgroup 'cpu' controller support : PASS
QEMU: Checking for cgroup 'cpu' controller mount-point: PASS
QEMU: Checking for cgroup 'cpuacct' controller support : PASS
QEMU: Checking for cgroup 'cpuacct' controller mount-point : PASS
QEMU: Checking for cgroup 'devices' controller support : PASS
QEMU: Checking for cgroup 'devices' controller mount-point : PASS
QEMU: Checking for cgroup 'net_cls' controller support : PASS
QEMU: Checking for cgroup 'net_cls' controller mount-point : PASS
QEMU: Checking for cgroup 'blkio' controller support : PASS
QEMU: Checking for cgroup 'blkio' controller mount-point : PASS
QEMU: Checking for device assignment IOMMU support  : WARN (No ACPI DMAR table found, IOMMU either disabled in BIOS or not supported by this hardware platform)`

我写的剧本如下。

`- hosts: localhost
   sudo: yes
   tasks:
    - name: Check if Host supports Virtualization.
      command: virt-host-validate qemu 
      ignore_errors: yes
      failed_when: false
      changed_when: false
      register: host_status
    - debug:
       msg: "status: {{host_status.stdout}}"`

现在令人担忧的部分是，除了警告之外是否还有任何其他任务失败，因为我们正在使用 ignore_errors: yes任何人都可以请指导我如何解决它？
提前致谢。

我可以用这个解决它。

  tasks:
   - name: Check if Host supports Virtualization.
     command: virt-host-validate qemu
     register: command_result
     failed_when:
       - "'FAIL' in command_result.stderr"
